eclipse整合spring+springMVC+Mybatis
一、新建Maven项目
点击菜单栏File项,选择New-》Project,选中Maven Project,如下图:
二、配置pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.newProject.framework</groupId> <artifactId>CreateFramework</artifactId> <version>1.0-SNAPSHOT</version> <properties> <!-- spring版本号 --> <spring.version>4.2.6.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.4.0</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.7.7</slf4j.version> <log4j.version>1.2.17</log4j.version> <!--jackson版本号--> <jackson.version>2.7.1</jackson.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <!-- 表示开发的时候引入,发布的时候不会加载此包 --> <!--<scope>test</scope>--> </dependency> <!-- spring核心包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.0</version> </dependency> <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4</version> </dependency> <!-- 导入Mysql数据库链接jar包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc14</artifactId> <version>10.2.0.2</version> </dependency> <!-- 导入dbcp的jar包,用来在applicationContext.xml中配置数据库 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <!-- JSTL标签类 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <!-- 格式化对象,方便输出日志 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!-- 映入JSON --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>${jackson.version}</version> </dependency> </dependencies> </project>
三、配置springMVC
在resources文件夹下建立spring-mvc.xml,如下图
具体内部配置如下:
<?xml version="1.0" encoding="UTF-8" ?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描该包,使用SpringMVC认为包下用了@Controller注解的类是控制器,避免扫描@Service导致事务不能使用 --> <context:component-scan base-package = "fv"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/> </context:component-scan> <!--避免IE执行AJAX时,返回JSON出现下载文件 --> <bean id = "mappingJacksonHttpMessageConverter" class = "org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name = "supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动SpringMVC的注解功能,完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="order" value="1"/> <property name="defaultViews"> <list> <!-- JSON View --> <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"> </bean> </list> </property> </bean> <!-- 定义跳转的文件的前后缀 ,视图模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 自动给后面action的方法return的字符串加上前缀和后缀,变成一个 可用的url地址 --> <property name="prefix" value="/WEB-INF/page/" /> <property name="suffix" value=".jsp" /> <!-- <property name="viewClass" value="org.springframework.web.servlet.view.InternalResourceView"/> --> </bean> <!-- 文件上传 --> <!-- <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize" value="102400000"></property> </bean> --> <!-- <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/mvc/**"/> <bean class="test.SpringMVC.Interceptor.MyInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> --> <!-- 添加后可以显示welcome-file界面 --> <mvc:default-servlet-handler/> <!-- 启动注解 --> <mvc:annotation-driven /> </beans>
四、整合mybatis
在resource文件夹下建立spring-mybatis.xml文件夹,配置内容如下:
<?xml version="1.0" encoding="UTF-8" ?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 自动扫描 --> <context:component-scan base-package="fv"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 引入数据库配置文件 --> <bean id = "propertyConfigurer" class = "org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer"> <property name = "location" value="classpath:jdbc.properties" /> </bean> <!-- 连接池 --> <bean id = "dataSource" class = "org.apache.commons.dbcp.BasicDataSource" destroy-method = "close"> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="${jdbc.initialSize}" /> <!-- 连接池最大数量 --> <property name="maxActive" value="${jdbc.maxActive}"/> <!-- 连接池最大空闲 --> <property name="maxIdle" value="${jdbc.maxIdle}" /> <!-- 连接池最小空闲 --> <property name="minIdle" value="${jdbc.minIdle}" /> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="${jdbc.maxWait}" /> </bean> <!-- 结合Spring和Mybatis --> <bean id = "sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name = "mapperLocations" value="classpath:fv/mapping/*.xml" /> </bean> <!-- DAO接口所在包名,Spring会自动查找其下的类 --> <bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name = "basePackage" value="fv.dao" /> <property name = "sqlSessionFactoryBeanName" value = "sqlSessionFactory" /> </bean> <!-- 定义事务 --> <bean id = "transactionManager" class = "org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name = "dataSource" ref = "dataSource" /> </bean> <!-- 使用注解定义事务 --> <tx:annotation-driven transaction-manager = "transactionManager" /> </beans>
五、配置属性文件
在此总共有两个属性文件,一个是log4j.properties,另一哥是数据库连接文件jdbc.properties;
log4j.properties文件内容如下:
#定义LOG输出级别 log4j.rootLogger=INFO,Console,File #定义日志输出目的地为控制台 log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.Target=System.out #可以灵活地指定日志输出格式,下面一行是指定具体的格式 log4j.appender.Console.layout = org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n #文件大小到达指定尺寸的时候产生一个新的文件 log4j.appender.File = org.apache.log4j.RollingFileAppender #指定输出目录 log4j.appender.File.File = logs/ssm.log #定义文件最大大小 log4j.appender.File.MaxFileSize = 10MB # 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志 log4j.appender.File.Threshold = ALL log4j.appender.File.layout = org.apache.log4j.PatternLayout log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
jdbc.properties文件如下:
jdbc.driver=oracle.jdbc.driver.OracleDriver jdbc.url=jdbc:oracle:thin:@192.168.1.213:1521:orcl jdbc.username=KYYS jdbc.password=kyys #定义初始连接数 jdbc.initialSize=0 #定义最大连接数 jdbc.maxActive=20 #定义最大空闲 jdbc.maxIdle=20 #定义最小空闲 jdbc.minIdle=1 #定义最长等待时间 jdbc.maxWait=60000
在webapp/WEB-INF/下web.xml文件内容如下:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>Archetype Created Web Application</display-name> <!-- Spring和Mybatis的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- configure the HiddenHttpMethodFilter,convert the post method to put or delete --> <!-- <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> --> <!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring MVC servlet --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <!-- 容器在启动时就加载这个servlet --> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 设置默认首页 --> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
六、程序内容
程序目录结构如下如:
index.jsp页面内容:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> 测试框架<a href="test/index" method ="POST">登录</a> <form action= "test/indexPost" method ="POST"> <input type= "submit" value ="测试登录"/> </form > <form action= "home/gohome" > <input type= "text" id="id" name="id" value ="0"/> <input type= "submit" value ="测试登录"/> </form > <form action= "home/index" > <input type= "submit" value ="测试登录"/> </form > </body> </html>
Controller控制器
package fv.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; @Controller @RequestMapping(value = "/home") public class HomeController { @RequestMapping(value = "/gohome", method = RequestMethod.GET) @ResponseBody public String goToHome(@RequestParam("id") String id) { return "this is my home";//Integer.parseInt(id) } @RequestMapping(value = "/index",method = RequestMethod.GET) public String index() { return "/admin"; } }
package fv.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import fv.Service.TestService; @Controller @RequestMapping("/test") public class TestController { //@Autowired private TestService testServiceImp;// @RequestMapping(value = "/get", method = RequestMethod.GET) @ResponseBody public String getTestByName(@RequestParam("id") String id) { return testServiceImp.getByName(0L);//Integer.parseInt(id) } @RequestMapping(value = "/hello", method = RequestMethod.GET) @ResponseBody public String HellowWorld(@RequestParam("id") String id) { return "Hello World";//Integer.parseInt(id) } @RequestMapping(value = "/index",method = RequestMethod.GET) public String index() { return "/admin"; } @RequestMapping(value = "/indexPost") public String indexPost() { return "/admin"; } }
dao层Mapper接口:
package fv.dao; public interface HomeMapper { String getByName(Long id); }
package fv.dao; public interface TestMapper { String getByName(Long id); }
mapping文件xml
<?xml version="1.0" encoding="UTF-8"?> <!-- <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-.dtd"> --> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="fv.dao.HomeMapper"> <!-- <resultMap id="BaseResultMap" type="fv.pojo.Test"> <id column="id" property="id" jdbcType="INTEGER" /> <result column="test1" property="test1" jdbcType="INTEGER" /> <result column="test2" property="test2" jdbcType="VARCHAR" /> </resultMap> --> <!-- <select id="getByName" parameterType="Long" resultType="String"> <![CDATA[ SELECT NAME FROM TM_SYS_EMPLOYEE WHERE ID=#{id} ]]> </select> --> <select id="getByName" resultType="java.lang.String"> SELECT NAME FROM TM_SYS_EMPLOYEE WHERE ID=#{id} </select> </mapper>
<?xml version="1.0" encoding="UTF-8"?> <!-- <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-.dtd"> --> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="fv.dao.TestMapper"> <!-- <resultMap id="BaseResultMap" type="fv.pojo.Test"> <id column="id" property="id" jdbcType="INTEGER" /> <result column="test1" property="test1" jdbcType="INTEGER" /> <result column="test2" property="test2" jdbcType="VARCHAR" /> </resultMap> --> <!-- <select id="getByName" parameterType="Long" resultType="String"> <![CDATA[ SELECT NAME FROM TM_SYS_EMPLOYEE WHERE ID=#{id} ]]> </select> --> <select id="getByName" resultType="java.lang.String"> SELECT NAME FROM TM_SYS_EMPLOYEE WHERE ID=#{id} </select> </mapper>
服务层
package fv.Service; public interface HomeService { String getByName(Long id); }
package fv.Service; import org.springframework.beans.factory.annotation.Autowired; import fv.dao.HomeMapper; public class HomeServiceImp { @Autowired(required = false) private HomeMapper testMapper=null; public String getByName(Long id) { return testMapper.getByName(id); } }
package fv.Service; public interface TestService { String getByName(Long id); }
package fv.Service; import org.springframework.beans.factory.annotation.Autowired; import fv.dao.TestMapper; public class TestServiceImp implements TestService { @Autowired(required = false) private TestMapper testMapper=null; public String getByName(Long id) { return testMapper.getByName(id); } }
类目录如下图:
admin.jsp页面如下:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> 登录成功!<a href="../test/hello?id=0">测试方法</a><%-- ${dynamicURL} --%> <a href="../home/gohome?id=0">测试重定向</a> </body> </html>
