我正在尝试使用Enverse在我保存,更新或删除数据库中的条目时审核表。
Envers配置如下:
的pom.xml
<!-- Spring -->
<org.springframework-version>4.1.6.RELEASE</org.springframework-version>
<!-- Hibernate -->
<hibernate.version>4.3.5.Final</hibernate.version>
[...]

</dependency>

我的每个域类都有@Audited
注释,但在DB中,这些字段始终为null
。
我不明白什么是错的,有什么建议吗?
修改
对评论的回应:每个实体类都扩展了一个实现Auditable方式的抽象域。请遵循以下代码:
@SuppressWarnings("serial")
@MappedSuperclass
@Audited
public abstract class AbstractDomain implements Auditable<String, Long>, Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
@Version
private int version;
@JsonIgnore
@Column(updatable=false)
private String createdBy;
@Type(type="org.jadira.usertype.dateandtime.joda.PersistentDateTime")
@DateTimeFormat(iso=ISO.DATE_TIME)
@JsonIgnore
@Column(updatable=false)
private DateTime createdDate;
@JsonIgnore
private String lastModifiedBy;
@Type(type="org.jadira.usertype.dateandtime.joda.PersistentDateTime")
@DateTimeFormat(iso=ISO.DATE_TIME)
@JsonIgnore
private DateTime lastModifiedDate;
修改的唯一字段是版本,其他字段将被忽略。
答案 0 :(得分:2)
从我所看到的你实际上根本不需要envers
。 Envers更多的是存储revisions
您的数据( 当然可以用于审核目的)但如果您想要这些createdBy
,createdDate
,lastModifiedBy
,lastModifiedDate
字段有一个更简单的方法。
由于您已经在使用spring-data-jpa
,我建议您使用JPA auditing
注释启用@EnableJpaAuditing
。
然后,您可以从@Audited
类中删除AbstractDomain
并添加@EntityListeners(AuditingEntityListener.class)
,这将强制hibernate在每次实体持久保存时保存审核信息。
最后但并非最不重要的事情是定义AuditorAware
bean。它将告诉每个时刻谁正在操纵给定实体,因此审计监听器将知道应该将哪些数据设置为createdBy
和lastModifiedBy
字段。
这很简单,这是一个例子:
@Bean
AuditorAware auditor() {
// return () -> "system"; // Fixed principal
// and for spring-security
return () -> {
Authentication authentication = SecurityContextHolder.getContext()
.getAuthentication();
if (authentication == null || !authentication.isAuthenticated()) {
return null;
}
return authentication.getPrincipal().toString();
}
}
就是这样。
以下是一个完整的例子:
@SpringBootApplication
@EnableJpaAuditing
public class So45347635Application {
public static void main(String[] args) { SpringApplication.run(So45347635Application.class, args); }
@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public static abstract class AbstractDomain extends AbstractPersistable<Long> implements Auditable<String, Long> {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Version
private int version;
@Column(updatable = false)
private String createdBy;
@Temporal(TemporalType.TIMESTAMP)
@Column(updatable = false)
private Date createdDate;
private String lastModifiedBy;
@Temporal(TemporalType.TIMESTAMP)
@Column(insertable = false)
private Date lastModifiedDate;
@Override
public String getCreatedBy() {
return this.createdBy;
}
@Override
public void setCreatedBy(String createdBy) {
this.createdBy = createdBy;
}
@Override
public DateTime getCreatedDate() {
return null == this.createdDate ? null : new DateTime(this.createdDate);
}
@Override
public void setCreatedDate(DateTime createdDate) {
this.createdDate = createdDate.toDate();
}
@Override
public String getLastModifiedBy() {
return this.lastModifiedBy;
}
@Override
public void setLastModifiedBy(String lastModifiedBy) {
this.lastModifiedBy = lastModifiedBy;
}
@Override
public DateTime getLastModifiedDate() {
return null == this.lastModifiedDate ? null : new DateTime(this.lastModifiedDate);
}
@Override
public void setLastModifiedDate(DateTime lastModifiedDate) {
this.lastModifiedDate = lastModifiedDate.toDate();
}
}
@Entity
@Table(name = "users")
public static class User extends AbstractDomain {
private String username = "anonymous";
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@Override
public String toString() {
return String.format("User{id=%d, createdBy='%s', createdDate=%s, lastModifiedBy='%s', lastModifiedDate=%s, username='%s'}",
getId(), getCreatedBy(), getCreatedDate(), getLastModifiedBy(), getLastModifiedDate(), username);
}
}
@Bean
AuditorAware auditor() { return () -> "system"; }
@Bean
CommandLineRunner start(UserRepository userRepository, TransactionTemplate tx) {
return args -> tx.execute(ctx -> {
final User user = userRepository.save(new User());
user.setUsername("admin");
System.out.println(">>>> " + userRepository.save(user));
return null;
});
}
}
interface UserRepository extends CrudRepository<So45347635Application.User, Long> {
}
输出:
create table users (id bigint generated by default as identity, created_by varchar(255), created_date timestamp, last_modified_by varchar(255), last_modified_date timestamp, version integer not null, username varchar(255), primary key (id));
insert into users (id, created_by, created_date, last_modified_by, version, username) values (null, 'system', '28-Jul-17', 'system', 0, 'anonymous');
update users set last_modified_by='system', last_modified_date='28-Jul-17', version=1, username='admin' where id=1 and version=0;
