当前最火热的SSM框架整合教程，超级详细版

直接到正题，利用了最新稳定的框架

需要自己在Maven下搭建web工程

提示：实体类和mapping文件是通过MybatisGeneraor生成，详情百度，Service层只是简单的调用mapper

UserServiceImpl.java

packageper.ssm.service.impl;importjavax.annotation.Resource;importorg.springframework.stereotype.Service;importper.ssm.mapper.UserMapper;importper.ssm.service.UserService;@ServicepublicclassUserServiceImplimplementsUserService{@ResourceprivateUserMapperuserMapper;@OverridepublicStringgetUserById(StringuserId){returnuserMapper.getName(userId);}}

UserController.java

packageper.ssm.controller;importjavax.servlet.http.HttpServletRequest;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.stereotype.Controller;importorg.springframework.ui.Model;importorg.springframework.web.bind.annotation.RequestMapping;importper.ssm.service.UserService;@Controller@RequestMapping("/user")publicclassUserController{@AutowiredprivateUserServiceuserService;@RequestMapping("/showUser")publicStringtoIndex(HttpServletRequestrequest,Modelmodel){Stringusername=userService.getUserById("1");model.addAttribute("username",username);return"showUser";}}

这是所需要的所有的配置文件，配置完成后，测试配置是否成功，

数据库里面先存了一条数据

index.jsp页面：

<html><body><h3>MainPage</h3><formaction="user/showUser"><inputtype="submit"value="user/showUser"/></form></body></html>

showUser.jsp页面(页面在WEB-INF/views下面)

<%@pagelanguage="java"contentType="text/html;charset=UTF-8"pageEncoding="UTF-8"%><!DOCTYPEhtmlPUBLIC"-//W3C//DTDHTML4.01Transitional//EN""http://www.w3.org/TR/html4/loose.dtd"><html><head><metahttp-equiv="Content-Type"content="text/html;charset=UTF-8"><title>showUsere</title></head><body>用户名：${username}</body></html>

点击提交显示数据库中的数据则成功。
