一、用户查询
1、创建UserController
package com.itzheng.ssm.controller;
import com.itzheng.ssm.domain.UserInfo;
import com.itzheng.ssm.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userService;
@RequestMapping("/findAll.do")
public ModelAndView findAll() throws Exception{
ModelAndView mv = new ModelAndView();
List<UserInfo> userList = userService.findAll();
return mv;
}
}
2、在业务层当中
（1）完善IUserService
（2）完善UserServiceImpl
@Override
public List<UserInfo> findAll() throws Exception {
return userDao.findAll();
}
（3）在IUserDao当中创建findAll()
@Select("select * from users")
List<UserInfo> findAll() throws Exception;
（4）完善UserController当中的findAll方法
添加数据以及设置跳转页面
package com.itzheng.ssm.controller;
import com.itzheng.ssm.domain.UserInfo;
import com.itzheng.ssm.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userService;
@RequestMapping("/findAll.do")
public ModelAndView findAll() throws Exception{
ModelAndView mv = new ModelAndView();
List<UserInfo> userList = userService.findAll();
mv.addObject("userList",userList);
mv.setViewName("user-list");
return mv;
}
}
（5）创建user-list.jsp
