这篇文章主要介绍了基于Spring Data的AuditorAware审计功能的示例代码，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
Spring Data提供支持审计功能：即由谁在什么时候创建或修改实体。Spring Data提供了在实体类的属性上增加@CreatedBy，@LastModifiedBy，@CreatedDate，@LastModifiedDate注解，并配置相应的配置项，即可实现审计功能，有系统自动记录 createdBy CreatedDate lastModifiedBy lastModifiedDate 四个属性的值，下面为具体的配置项。
示例
package com.hfcsbc.infrastructureservice.domain; import com.hfcsbc.repository.support.domain.AbstractAuditingEntity; 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 javax.persistence.*; import java.util.Date; /** * Create by pengchao on 2018/3/7 */ @Entity @Data @EntityListeners({AuditingEntityListener.class}) public class Person { @Id @GeneratedValue private Long id; private String name; private Integer age; @CreatedBy @Column( name = "created_by", nullable = false, length = 50, updatable = false ) private String createdBy; @CreatedDate @Column( name = "created_date", nullable = false, updatable = false ) private Date createdDate = new Date(); @LastModifiedBy @Column( name = "last_modified_by", length = 50 ) private String lastModifiedBy; @LastModifiedDate @Column( name = "last_modified_date" ) private Date lastModifiedDate = new Date(); }
创建相应的Repository
package com.hfcsbc.repository; import com.hfcsbc.domain.Person; import org.springframework.data.jpa.repository.JpaRepository; /** * Create by pengchao on 2018/3/7 */ public interface PersonRepository extends JpaRepository { }
package com.hfcsbc.infrastructureservice.config; import org.springframework.data.domain.AuditorAware; import org.springframework.security.core.Authentication; import org.springframework.security.core.context.SecurityContextHolder; import org.springframework.stereotype.Component; import java.util.Optional; /** * Create by pengchao on 2018/3/7 */ @Component("auditorAware") public class AuditorAwareImpl implements AuditorAware { @Override public Optional getCurrentAuditor() { Authentication authentication = SecurityContextHolder.getContext().getAuthentication(); return Optional.of(authentication.getPrincipal().toString()); } }
在Spring Boot入口类开启审计功能
package com.hfcsbc.infrastructureservice; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.data.jpa.repository.config.EnableJpaAuditing; import org.springframework.scheduling.annotation.EnableAsync; @SpringBootApplication @EnableJpaAuditing(auditorAwareRef = "auditorAware") @EnableAsync public class PersonApplication { public static void main(String[] args) { SpringApplication.run(PersonApplication.class, args); } }
即完成配置，在使用 repository 保存对象时， createdBy CreatedDate lastModifiedBy lastModifiedDate 有审计功能自动插入
由于在异步方法中使用repository保存对象，获取不到用户用户信息，需增加如下配置项，即可在Authentication获取用户的信息
package com.hfcsbc.config; import org.springframework.beans.factory.config.MethodInvokingfactorybean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.core.context.SecurityContextHolder; /** * Create by pengchao on 2018/3/7 */ @Configuration public class AuditorAwareConfig { @Bean public MethodInvokingfactorybean methodInvokingfactorybean() { MethodInvokingfactorybean methodInvokingfactorybean = new MethodInvokingfactorybean(); methodInvokingfactorybean.setTargetClass(SecurityContextHolder.class); methodInvokingfactorybean.setTargetmethod("setStrategyName"); methodInvokingfactorybean.setArguments(new String[]{SecurityContextHolder.MODE_INHERITABLETHREADLOCAL}); return methodInvokingfactorybean; } }
SecurityContextHolder的主要功能是将当前执行的进程和SecurityContext关联起来。
SecurityContextHolder.MODE_INHERITABLETHREADLOCAL ：用于线程有父子关系的情景中，子线程集成父线程的SecurityContextHolder；
SecurityContextHolder.MODE_INHERITABLETHREADLOCAL ：全局共用SecurityContextHolder。
