数据库连接mysql和Spring框架

我想用数据库名称：myschema，table：user（带有3列 - > id，用户名，密码）获取数据。但未能加载。数据库连接mysql和Spring框架

我的项目结构：

控制器：

package com.project.pr.controller; 

import java.util.List; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.http.HttpStatus; 
import org.springframework.web.bind.annotation.GetMapping; 
import org.springframework.web.bind.annotation.ResponseStatus; 
import org.springframework.web.bind.annotation.RestController; 

import com.project.pr.entity.User; 
import com.project.pr.service.ProjectService; 

@RestController 
public class ProjectController { 

    @Autowired 
    private ProjectService projectService; 

    @GetMapping(name="user") 
    @ResponseStatus(HttpStatus.OK) 
    public List<User> getUser(){ 
     return projectService.getUser(); 
    } 

}

服务：

package com.project.pr.service; 

import java.util.List; 

import javax.transaction.Transactional; 

import org.hibernate.SessionFactory; 
import org.hibernate.transform.Transformers; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Repository; 

import com.project.pr.entity.User; 

@Repository 
public class ProjectService { 

    @Autowired 
    private SessionFactory sessionFactory; 

    @Transactional 
    public List<User> getUser() { 
     String sql = "SELECT * FROM USER"; 
     List result = this.sessionFactory.getCurrentSession().createSQLQuery(sql).setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP).list(); 
     return result; 
    } 

}

实体：

package com.project.pr.entity; 

import java.io.Serializable; 

import javax.persistence.Column; 
import javax.persistence.Entity; 
import javax.persistence.Id; 
import javax.persistence.Table; 

@Entity 
@Table(name="USER") 
public class User implements Serializable { 

    @Id 
    @Column(name="id") 
    private String id; 

    @Column(name="username") 
    private String username; 

    @Column(name="password") 
    private String password; 

    public String getId() { 
     return id; 
    } 

    public void setId(String id) { 
     this.id = id; 
    } 

    public String getUsername() { 
     return username; 
    } 

    public void setUsername(String username) { 
     this.username = username; 
    } 

    public String getPassword() { 
     return password; 
    } 

    public void setPassword(String password) { 
     this.password = password; 
    } 

}
