springboot 整合jdbcTemplate
〇、搭建springboot环境(包括数据库的依赖)
一、添加依赖
如果导入了jpa的依赖,就不用导入jdbctemplete的依赖了jpa的依赖:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
如果没有导入jpa的包则要导入jdbcTemplete的包:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
二、配置文件
########################################################
###datasource
########################################################
spring.datasource.url = jdbc:mysql://localhost:3306/mine
spring.datasource.username = root
spring.datasource.password = root
spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.datasource.max-active=20
spring.datasource.max-idle=8
spring.datasource.min-idle=8
spring.datasource.initial-size=10
三、持久层
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;
import com.xujie.pojo.User;
@Repository
public class UserDao {
@Autowired
private JdbcTemplate jdbcTemplate;
public void save(User user) {
String sql = "insert into user (uname) values (‘"+user.getUname()+"‘)";
this.jdbcTemplate.update(sql);
}
}
四、service
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.xujie.dao.UserDao;
import com.xujie.pojo.User;
import com.xujie.service.UserService;
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public void save(User user) {
this.userDao.save(user);
}
}
五、Controller
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import com.xujie.pojo.User;
import com.xujie.service.UserService;
@RestController
public class UserController {
@Autowired
private UserService userService;
@GetMapping("/save")
public void save() {
User user = new User();
user.setUname("yuanxiliu");
this.userService.save(user);
}
}
