我可以在没有orm.xml文件的情况下使用Spring Data JPA Auditing(使用JavaConfig代替)吗?
我正在尝试让Spring Data Auditing在我的Spring 3.2.8 / Spring Data 1.5 / Hibernate 4项目中运行。
I'm trying to get Spring Data Auditing to work in my Spring 3.2.8 / Spring Data 1.5 / Hibernate 4 project.
根据 Spring Data Auditing docs ,我已经将 @CreatedBy
等注释添加到我的实体,由 AuditorAware
实现创建,并从内部实例化我的JavaConfig。然而,它似乎永远不会发生。
As per the Spring Data Auditing docs, I've added the @CreatedBy
, etc annotations to my entities, created by AuditorAware
implementation, and instantiated it from within my JavaConfig. However, it never seems to fire.
我发现文档有点令人困惑。似乎JavaConfig条目替换了xml条目,但我不确定。
I find the docs a little confusing. It appears that the JavaConfig entry replaces the xml entry, but I am not sure.
我目前没有任何 orm.xml
我的申请中的文件。说实话,我甚至不确定在哪里/如何配置它,或者为什么我需要它。我的所有实体都在使用注释。我已经尝试将@EntityListeners(AuditingEntityListener.class)添加到实体,但这没有帮助。
I don't currently have any orm.xml
file in my application. To be entirely honest, I'm not even sure where/how to configure it, or why I need it. All my entities are using annotations. I have tried adding @EntityListeners(AuditingEntityListener.class) to the entity, but that has not helped.
我的当前实体管理器是在没有persistence.xml文件的情况下定义的:
My current entity manager is defined without a persistence.xml file:
<!-- entity manager -->
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter"/>
<property name="packagesToScan" value="com.ia.domain"/>
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
<prop key="hibernate.query.substitutions">true '1', false '0'</prop>
<prop key="hibernate.generate_statistics">true</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop>
<prop key="hibernate.connection.charSet">UTF-8</prop>
</props>
</property>
</bean>
JavaConfig:
JavaConfig:
@Configuration
@EnableJpaAuditing
public class AuditConfig {
@Bean
public AuditorAware<User> auditorProvider(){
return new SpringSecurityAuditorAware();
}
}
实体:
@EntityListeners({AuditingEntityListener.class})
@Entity
public class User
{
@TableGenerator(name="UUIDGenerator", pkColumnValue="user_id", table="uuid_generator", allocationSize=1)
@Id
@GeneratedValue(strategy=GenerationType.TABLE, generator="UUIDGenerator")
@Column(name="id")
private Long id;
@NotNull
private String username;
@CreatedDate
@NotNull
@Temporal(TemporalType.TIMESTAMP)
@Column(name="created_date", nullable=false)
private Date createdDate;
@LastModifiedDate
@NotNull
@Temporal(TemporalType.TIMESTAMP)
@Column(name="last_modified_date", nullable=false)
private Date lastModifiedDate;
@CreatedBy
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="created_by")
private User createdBy;
@LastModifiedBy
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="last_modified_by")
private User lastModifiedBy;
private String password;
private Boolean enabled;
...
}
I我已经在我的 SpringSecurityAuditorAware
类中设置了一个断点但它永远不会被击中。
I've put a breakpoint in my SpringSecurityAuditorAware
class but it is never being hit.
我还需要一个orm吗? .xml文件?如何/在哪里引用EntityManager?
Do I still need an orm.xml file? How/where is this referenced from the EntityManager?
使用Stephan的答案, https://stackoverflow.com/a/26240077/715640 ,
Using Stephan's answer, https://stackoverflow.com/a/26240077/715640,
我使用自定义监听器工作了。
I got this working using a custom listener.
@Configurable
public class TimestampedEntityAuditListener {
@PrePersist
public void touchForCreate(AbstractTimestampedEntity target) {
Date now = new Date();
target.setCreated(now);
target.setUpdated(now);
}
@PreUpdate
public void touchForUpdate(AbstractTimestampedEntity target) {
target.setUpdated(new Date());
}
}
然后在我的基类中引用它:
And then referencing it in my base class:
@MappedSuperclass
@EntityListeners({TimestampedEntityAuditListener.class})
public abstract class AbstractTimestampedEntity implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE)
private Long id;
@Temporal(TemporalType.TIMESTAMP)
private Date created;
@Temporal(TemporalType.TIMESTAMP)
private Date updated;
public Date getCreated() {
return created;
}
public void setCreated(Date created) {
this.created = created;
}
public Date getUpdated() {
return updated;
}
public void setUpdated(Date updated) {
this.updated = updated;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
FWIW,我在春天使用它 - 启动项目,没有orm.xml文件。
FWIW, I'm using this in a spring-boot project, without an orm.xml file.
