配置spring data jpa的 Auditor审计功能

配置hibernate Auditor审计； 在实体中通过添加注解，自动获取当前修改，添加人员信息；

在spring boot的入口处开启审计功能 @EnableJpaAuditing(auditorAwareRef = "auditorAware")

UserAuditorAware.java
content_copyfile_download
import org.springframework.context.annotation.Configuration;
import org.springframework.data.domain.AuditorAware;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;

import java.util.Optional;

@Configuration
public class UserAuditorAware implements AuditorAware<String> {

    @Override
    public Optional<String> getCurrentAuditor() {
        SecurityContext ctx = SecurityContextHolder.getContext();
        if (ctx == null) {
            return Optional.empty();
        }
        if (ctx.getAuthentication() == null) {
            return Optional.empty();
        }
        if (ctx.getAuthentication().getPrincipal() == null) {
            return Optional.empty();
        }
        Object principal = ctx.getAuthentication().getPrincipal();
        if (principal.getClass().isAssignableFrom(User.class)) {
            return Optional.of(((User) principal).getUsername());
        } else {
            return Optional.empty();
        }
    }
}
Model.java
content_copyfile_download
@Entity
@EntityListeners(AuditingEntityListener.class)
@JsonInclude( JsonInclude.Include.NON_NULL)
@JsonIgnoreProperties(value = { "hibernateLazyInitializer", "handler" })
public class Model implements Serializable{

	@Id
	@Column(unique = true, nullable = false,columnDefinition = "bigint")
	@GeneratedValue(strategy= GenerationType.IDENTITY)
