SpringBoot+SpringDataJPA+SpringBoot单元测试
- 没写页面,controller层通过rest进行测试
1.新建SpringBoot项目

2.添加依赖
<!--配置springbootJPA-->

3.编辑application.properties文件
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql://localhost:3307/jpadatabase?useSSL=false&serverTimezone=UTC&characterEncoding=utf-8
# jpa connect mysql
spring.jpa.database=mysql
# jpa show sql
spring.jpa.show-sql=true
# jap format sql 格式化SQL语句
spring.jpa.properties.hibernate.format_sql=true
# create-drop create update validate
spring.jpa.hibernate.ddl-auto=update
4.pojo层User.java
package com.ym.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import javax.persistence.*;
@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(name = "users") //数据库自定生成的表名
public class Users {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY) //设置自增
@Column(name = "uid")
private int uid;
@Column(name = "user_name",length = 25,unique = true,nullable = false)
private String userName; //字段名user_name,长度25,唯一,非空
@Column(name = "password",length = 25,unique = true,nullable = false)
private String password;
}
5.dao层IUserDao.java
package com.ym.dao;
import com.ym.pojo.Users;
import org.springframework.data.jpa.repository.JpaRepository;
import java.util.List;
public interface IUserDao extends JpaRepository<Users,Integer> {
//自定义除了自身集成以外的其他方法
List<Users> findByUserName(String userName);
List<Users> findByPassword(String password);
}
6.service层的接口
package com.ym.service;
import com.ym.pojo.Users;
import java.util.List;
public interface IUserService {
List<Users> getAllUser();
void saveUsers(Users users);
List<Users> getUserByUserName(String userName);
List<Users> getUserByPassword(String password);
}
7.service层实现类
package com.ym.service.impl;
import com.ym.dao.IUserDao;
import com.ym.pojo.Users;
import com.ym.service.IUserService;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.List;
@Service
public class UserService implements IUserService {
@Resource
private IUserDao userDao;
@Override
public List<Users> getAllUser() {
return userDao.findAll();
}
@Override
public void saveUsers(Users users) {
userDao.save(users);
}
@Override
public List<Users> getUserByUserName(String userName) {
return userDao.findByUserName(userName);
}
@Override
public List<Users> getUserByPassword(String password) {
return userDao.findByPassword(password);
}
}
8.service层的单元测试(SpringBoot)
package com.ym.service;
import com.ym.pojo.Users;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import javax.annotation.Resource;
import java.util.List;
@RunWith( SpringRunner.class ) //不加此注解会报错
@SpringBootTest
public class UserServiceTest {
@Resource
private IUserService userService;
@Test
public void saveUser(){
userService.saveUsers(new Users(1,"root","root"));
}
@Test
public void getAllUser(){
List<Users> users = userService.getAllUser();
for (Users user : users) {
System.out.println(user);
}
}
@Test
public void getUserByName(){
List<Users> users = userService.getUserByUserName("root");
for (Users user : users) {
System.out.println(user);
}
}
@Test
public void getUserByPassword(){
List<Users> users = userService.getUserByPassword("root");
for (Users user : users) {
System.out.println(user);
}
}
}
9.controller层UserController.java
package com.ym.controller;
import com.ym.pojo.Users;
import com.ym.service.IUserService;
import org.junit.Test;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;
import java.util.List;
@RestController
public class UserController {
@Resource
private IUserService userService;
@GetMapping("/allUser")
public List<Users> getAllUser(){
List<Users> users = userService.getAllUser();
return users;
}
@GetMapping("/UserByName")
public List<Users> getUserByName(String userName){
List<Users> users = userService.getUserByUserName(userName);
return users;
}
@GetMapping("/UserByPassword")
public List<Users> getUserByPassword(String password){
List<Users> users = userService.getUserByPassword(password);
return users;
}
}
