在myeclipse上整合ssm框架

1、所有需要的JAR包都引入以后，首先进行Spring与MyBatis的整合，然后再进行JUnit测试，先看一个项目结构图：

2、建立spring-mybatis.xml配置文件烂瘀佐栾这个文件就是用来完成spring和mybatis的整合的。这里诹鬃蛭镲面也没多少行配置，主要的就是自动扫描，自动注入，配置数据库。注释也很详细，大家看看就明白了。spring-mybatis.xml<?xmlversion="1.0"encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.1.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.1.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><context:component-scanbase-package="com.cn.hnust"/><beanid="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><propertyname="location"value="classpath:jdbc.properties"/></bean><beanid="dataSource"class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close"><propertyname="driverClassName"value="${driver}"/><propertyname="url"value="${url}"/><propertyname="username"value="${username}"/><propertyname="password"value="${password}"/><propertyname="initialSize"value="${initialSize}"></property><propertyname="maxActive"value="${maxActive}"></property><propertyname="maxIdle"value="${maxIdle}"></property><propertyname="minIdle"value="${minIdle}"></property><propertyname="maxWait"value="${maxWait}"></property></bean><beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean"><propertyname="dataSource"ref="dataSource"/><propertyname="mapperLocations"value="classpath:com/cn/hnust/mapping/*.xml"></property></bean><beanclass="org.mybatis.spring.mapper.MapperScannerConfigurer"><propertyname="basePackage"value="com.cn.hnust.dao"/><propertyname="sqlSessionFactoryBeanName"value="sqlSessionFactory"></property></bean><beanid="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><propertyname="dataSource"ref="dataSource"/></bean></beans>

3、利用MyBatis Generator自动创建代码这个可根据表自动创建实体类、MyBatis映射文件以及DAO接口，当然，我习惯将生成的接口名改为IUserDao，而不是直接用它生成的UserMapper。如果不想麻烦就可以不改。完成后将文件复制到工程中。如图：

4、配置spring-mvc.xml配置里面的注释也很详细，在此就不说了，主要是自动扫描控制器，砷啼硎实视图模式，注解的启动这三个。<?xmlversion="1.0"encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.1.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.1.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><context:component-scanbase-package="com.cn.hnust.controller"/><beanid="mappingJacksonHttpMessageConverter"class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"><propertyname="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value></list></property></bean><beanclass="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"><propertyname="messageConverters"><list><refbean="mappingJacksonHttpMessageConverter"/></list></property></bean><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><propertyname="prefix"value="/WEB-INF/jsp/"/><propertyname="suffix"value=".jsp"/></bean><beanid="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><propertyname="defaultEncoding"value="utf-8"/><propertyname="maxUploadSize"value="10485760000"/><propertyname="maxInMemorySize"value="40960"/></bean></beans>

5、配置web.xml文件这里面对spring-mybatis.xml的引入以及配置的spring-mvc的Servlet就是为了完成SSM整合，之前2框架整合不需要在此处进行任何配置。配置一样有详细注释，不多解释了。<?xmlversion="1.0"encoding="UTF-8"?><web-appxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"version="3.0"><display-name>ArchetypeCreatedWebApplication</display-name><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mybatis.xml</param-value></context-param><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><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><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><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><welcome-file-list><welcome-file>/index.jsp</welcome-file></welcome-file-list></web-app>
