2、Dao
package com.autohome.dao; import com.autohome.model.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.jdbc.core.JdbcTemplate; import org.springframework.jdbc.core.PreparedStatementSetter; import org.springframework.stereotype.Repository; import java.sql.PreparedStatement; import java.sql.SQLException; import java.sql.Types; import java.util.List; @Repository public class UserDao { @Autowired JdbcTemplate jdbcTemplate; public List<User> listAllUser() { List<User> list = jdbcTemplate.query("select * from t_userinfo",new User()); return list; } public int insertUser(final User user) { int result = jdbcTemplate.update("insert into t_userinfo (name,address) VALUES (?,?)", new PreparedStatementSetter() { public void setValues(PreparedStatement ps) throws SQLException { ps.setString(1,user.getName()); ps.setString(2,user.getAddress()); } }); return result; } public int updateUser(final User user) { int result = jdbcTemplate.update("UPDATE t_userinfo set name=?,address=? where id=?", new PreparedStatementSetter() { public void setValues(PreparedStatement ps) throws SQLException { ps.setString(1,user.getName()); ps.setString(2,user.getAddress()); ps.setInt(3,user.getId()); } }); return result; } public int deleteUser(int id) { int result = jdbcTemplate.update("delete from t_userinfo where id=?",new Object[]{id},new int[]{Types.INTEGER}); return result; } }
3、Service
package com.autohome.service; import com.autohome.dao.UserDao; import com.autohome.model.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service public class UserService { @Autowired UserDao userDao; public List<User> listAllUser(){ return userDao.listAllUser(); } public int insertUser(User user){ return userDao.insertUser(user); } public int updateUser(User user){ return userDao.updateUser(user); } public int deleteUser(int id){ return userDao.deleteUser(id); } }
4、Controller
package com.autohome.controller; import com.autohome.model.User; import com.autohome.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import java.util.List; /** * Created by zhangfei on 2017/6/22. */ @Controller @RequestMapping("/user") public class UserController { @ResponseBody @RequestMapping("/detail") public User detail(Integer id){ User user=new User(); user.setId(id); user.setName("zhangsan"); user.setAddress("china"); return user; } @Autowired UserService userService; @ResponseBody @RequestMapping("/list") public List<User> list(){ List<User> list = userService.listAllUser(); System.out.println("size:"+list.size()); return list; } @RequestMapping(value="/insert",method = RequestMethod.POST) public String insertUser(String name,String address){ User user =new User(); user.setName(name); user.setAddress(address); int result = userService.insertUser(user); if(result>0){ return "{\"returncode\":0,\"message\":\"success\"}"; }else{ return "{\"returncode\":0,\"message\":\"error\"}"; } } }
