1.实体类

package com.tiger.jpatest.entity;import jakarta.persistence.*;
import lombok.Data;
import org.springframework.data.annotation.CreatedBy;
import org.springframework.data.annotation.CreatedDate;
import org.springframework.data.annotation.LastModifiedBy;
import org.springframework.data.annotation.LastModifiedDate;
import org.springframework.data.jpa.domain.support.AuditingEntityListener;import java.util.Date;@Entity
@Table(name = "teacher")
@EntityListeners({AuditingEntityListener.class})
@Data
public class Teacher {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long id;private String name;@CreatedByprivate String createUserId;@LastModifiedByprivate String updateUserId;@CreatedDateprivate Date createTime;@LastModifiedDateprivate Date updateTime;}

2.审计配置类

package com.tiger.jpatest.config;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.domain.AuditorAware;
import org.springframework.data.jpa.repository.config.EnableJpaAuditing;import java.util.Optional;@EnableJpaAuditing
@Configuration(proxyBeanMethods = false)
public class TeacherAuditor {@Beanpublic AuditorAware<String> auditorProvider() {// TODO 获取当前主体 do something...return () -> Optional.of("123456");}}

3.执行repository方法

package com.tiger.jpatest.repository;import com.tiger.jpatest.entity.Teacher;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class TeacherDaoTest {@AutowiredTeacherDao teacherDao;@Testvoid name() {Teacher teacher1 = teacherDao.findById(2L).orElse(null);teacher1.setName("asd");teacherDao.save(teacher1);}
}

4.第二种配置

public class CustomEntityAuditingListener {@PrePersistprivate void prePersist(BaseEntity entity) {// 获取当前用户，具体获取逻辑请自行实现SysUser current = new SysUser();entity.setCreatorId(current.getId());entity.setCreator(current.getUsername());entity.setLastModifierId(current.getId());entity.setLastModifier(current.getUsername());}@PreUpdateprivate void preUpdate(BaseEntity entity) {// 获取当前用户，具体获取逻辑请自行实现SysUser current = new SysUser();entity.setLastModifierId(current.getId());entity.setLastModifier(current.getUsername());}
}

@Getter
@Setter
@Entity
@EntityListeners({AuditingEntityListener.class, CustomEntityAuditingListener.class})
public class SysUser implements Serializable {/*** ID，唯一标识列，使用主键自增策略*/@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long id;/*** 创建时间*/@CreatedDateprivate LocalDateTime createdTime;/*** 最后修改时间*/@LastModifiedDateprivate LocalDateTime lastModifiedTime;/*** 创建人ID*/@CreatedByprivate Long creatorId;/*** 创建人用户名*/private String creator;/*** 最后修改人ID*/@LastModifiedByprivate Long lastModifierId;  /*** 最后修改人用户名*/  private Long lastModifier;  /*** 用户名*/@Column(unique = true)private String username;/*** 密码*/private String password;/*** 电话*/private String phone;
}
