/project
三、 配置web.xml 由于这里有两个 spring的配置文件一个是Springmvc的配置文件一个是spring的配置文件所以 配置时将其改成了spring*.xml !DOCTYPE web-app PUBLIC-//Sun Microsystems, Inc.//DTD Web Application 2.3//ENhttp://java.sun.com/dtd/web-app_2_3.dtd web-appdisplay-nameArchetype Created Web Application/display-nameservletservlet-namespringmvc/servlet-nameservlet-classorg.springframework.web.servlet.DispatcherServlet/servlet-classinit-paramparam-namecontextConfigLocation/param-name!-- 这里 因为有两个spring的配置文件一个是springmvc的一个是 spring的所以在这里 写成了这样的。--param-valueclasspath:/spring*.xml/param-value/init-paramload-on-startup1/load-on-startup/servletservlet-mappingservlet-namespringmvc/servlet-nameurl-pattern//url-pattern/servlet-mapping
/web-app
四、 配置springMVC.xml
?xml version1.0 encodingUTF-8?
beans xmlnshttp://www.springframework.org/schema/beansxmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexmlns:contexthttp://www.springframework.org/schema/contextxmlns:mvchttp://www.springframework.org/schema/mvcxsi:schemaLocationhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd!-- 开启包扫描--context:component-scan base-packagecom.atguigu/context:component-scan!--开启springmvc的注解驱动--mvc:annotation-driven/!--开启静态资源拦截--mvc:default-servlet-handler/
/beans
五、 配置 spring.xml
?xml version1.0 encodingUTF-8?
beans xmlnshttp://www.springframework.org/schema/beansxmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexmlns:contexthttp://www.springframework.org/schema/contextxmlns:mvchttp://www.springframework.org/schema/mvc xmlns:txhttp://www.springframework.org/schema/txxsi:schemaLocationhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd!-- 加载配置文件--context:property-placeholder locationclasspath:jdbc.properties/context:property-placeholder!-- 开启数据源连接--bean iddataSource classcom.alibaba.druid.pool.DruidDataSourceproperty namedriverClassName value${jdbc.driver}/propertyproperty nameurl value${jdbc.url}/propertyproperty nameusername value${jdbc.username}/propertyproperty namepassword value${jdbc.password}/property/bean!--3.配置事务管理器--bean idtransactionManager classorg.springframework.jdbc.datasource.DataSourceTransactionManagerproperty namedataSource refdataSource//bean!--4.开启事务注解--tx:annotation-driven/!--5.Spring整合Mybatis--bean idsqlSessionFactory classorg.mybatis.spring.SqlSessionFactoryBean!--引入数据源--property namedataSource refdataSource/!--配置别名包--property nametypeAliasesPackage valuecom.atguigu.pojo/!--引入mybatis配置文件--property nameconfigLocation valueclasspath:/mybatis-config.xml/!--引入映射文件--property namemapperLocations valueclasspath:/mapper/*.xml/property/bean!--6.让spring为mapper接口创建代理对象 --bean idmapperScannerConfigurer classorg.mybatis.spring.mapper.MapperScannerConfigurerproperty namebasePackage valuecom.atguigu.mapper//bean/beans
六、 通过Mybatis逆向工程生成持久层代码
找到当前项目的 maven 插件 中的 Plugins 中的 mybatis-generator 进行双击
当运行成功之后会生成 三个文件夹和类 七、 编写业务代码。
