SSM框架结合html和jsp实现简单的查询功能

package com.mwc.test.controller; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import com.mwc.test.entity.User; import com.mwc.test.service.UserService; @Controller public class UserController { @Autowired UserService userservice; /** * 登录页面（html页面） * @return */ @RequestMapping("login") public String login(){ return "login"; } /** * 登录页面的确定调用的方法（html使用的方法） * @param id * @return */ @RequestMapping(value="/showall",method=RequestMethod.POST) @ResponseBody public User showall(String id){ Long userId = Long.parseLong(id); User user = this.userservice.getUserById(userId); return user; } /** * 显示的方法(jsp页面，这边直接把id跟在后面来进行一个显示) * @param request * @param model * @return */ @RequestMapping("/showUser") public String toIndex(HttpServletRequest request,Model model){ Long userId = Long.parseLong(request.getParameter("id")); User user = this.userservice.getUserById(userId); model.addAttribute("user", user); return "showUser"; } }
