IDE maven 创建spring boot 用hibernate 实现连接数据库

package com.jm.Model;

import javax.persistence.Entity;

@Entity

public class UserDB {

private int userid ;

private String username;

private String userno ;

public int getUserid() {

return userid;

}

public String getUsername() {

return username;

}

public String getUserno() {

return userno;

}

public void setUserid(int userid) {

this.userid = userid;

}

public void setUsername(String username) {

this.username = username;

}

public void setUserno(String userno) {

this.userno = userno;

}

}

package com.jm.controller;

import com.jm.Model.UserDB;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.GetMapping;

import java.util.List;

@Controller

public class UserController {

@Autowired

private UserDBRepository userdb;

/**查询所有用户列表*/

@GetMapping(value = "/users")

private List<UserDB> userList(){

System.out.println(userdb.findAll());

return userdb.findAll();

}

// /**添加一个女生*/

// @PostMapping(value="/users")

// public Girl girlAdd(@RequestParam("cupSize") String cupSize,

// @RequestParam("age") Integer age){

// Girl girl=new Girl();

// girl.setCupSize(cupSize);

// girl.setAge(age);

// return girlRepository.save(girl);

// }

// //查询一个女生

// @GetMapping(value = "/girls/{id}")

// public Girl girlFindOne(@PathVariable("id")Integer id){

// //更新

// girl.setAge(age);

// return girlRepository.save(girl);

// }

// //删除

// @DeleteMapping(value="/girls/{id}")

// public void girlDelete(@PathVariable("id") Integer id){

// girlRepository.delete(id);

// }

//

// //通过年龄查询女生列表

// @GetMapping(value = "/girls/age/{age}")

ERROR 1384 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

Process finished with exit code 0

原因是：springboot启动时会自动注入数据源和配置jpa

解决：在@SpringBootApplication中排除其注入

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})

加了之后，又报错
