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();
}
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> {
}
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());
}
}
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
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;
}
}
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。
