SpringBoot整合SpringDataJPA
1. 添加依赖
2. 添加配置文件
代码语言：javascript
复制# jdbc 的相关信息
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/logistics?characterEncoding=utf-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=123456
# 配置连接池信息
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
# 配置jpa的相关参数
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
3. 创建POJO
代码语言：javascript
复制package com.bobo.pojo;
import javax.persistence.*;
import java.io.Serializable;
@Table(name = "t_user")
@Entity
public class Users implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="user_id")
private Integer userId;
@Column(name="user_name")
private String usreName;
@Column(name="real_name")
private String realName;
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getUsreName() {
return usreName;
}
public void setUsreName(String usreName) {
this.usreName = usreName;
}
public String getRealName() {
return realName;
}
public void setRealName(String realName) {
this.realName = realName;
}
}
4. 创建接口
代码语言：javascript
复制package com.bobo.dao;
import com.bobo.pojo.Users;
import org.springframework.data.jpa.repository.JpaRepository;
public interface UsersRepository extends JpaRepository<Users,Integer> {
}
5. 测试
代码语言：javascript
复制package com.bobo;
import com.bobo.dao.UsersRepository;
import com.bobo.pojo.Users;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class SpringdatajpaSpringbootApplicationTests {
@Autowired
private UsersRepository dao;
@Test
void contextLoads() {
Users users = new Users();
users.setUsreName("test1");
users.setRealName("测试数据");
dao.save(users);
}
}
