spring boot(二): spring boot+jdbctemplate+sql server

2653885

前言
　　小项目或者做demo时可以使用jdbc+sql server解决即可，这篇就基于spring boot环境使用jdbc连接sql server数据库，和spring mvc系列保持一致。 在spring boot中使用jdbc 连接sql server数据只需要引入两个jar：spring-boot-starter-jdbc、spring-boot-starter-data-jpa

项目结构
　　和上篇spring boot入门保持相同

pom.xml

Application.java、Dao、Service、model
　　1、Application.java



@SpringBootApplication(scanBasePackages = "com.autohome")
public class Application extends SpringBootServletInitializer{
public static void main(String[] args){
System.out.println("server is running at 8080....");
SpringApplication.run(Application.class,args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
}
　　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\"}";
}
}

}
