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
创建一个实体类
- 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();
- }
复制代码
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<Person, Long> {
- }
复制代码
配置获取用户信息的bean
- 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<String> {
- @Override
- public Optional<String> getCurrentAuditor() {
- Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
- return Optional.of(authentication.getPrincipal().toString());
- }
- }
复制代码
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);
- }
- }
复制代码
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
注:在异步方法中如何获取用户信息
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;
- }
- }
复制代码
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。
