我掙扎了2天，試圖解決這個問題，我不知道我還能做什麼。我的系統工作得很好，直到我將@Audit包含在實體中。當然，我在.pom文件中包含了Hibernate Envers。審計+ spring-boot-data-jpa + Hibernate + JPA 2事務性異常
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-envers</artifactId>
</dependency>
我已經嘗試過這些帖子：
Hibernare envers Audit with Spring data JPA and Spring Boot
Hibernate-envers throwing exception when Deleting entity with a collection using CrudRepository
但遺憾的是沒有成功可言:(
我檢查我的maven repository，我注意到它使用hibernate-版本的hibernate-core，hibernate-entitymanager和hibernate-envers，無論我在.pom文件中設置了什麼版本。
這裏是我的.pom文件的依賴關係：

這Listener類
public class BRAuditEnversListener implements RevisionListener {
protected static final Logger log = Logger.getLogger("com.zerofila.web");
@Autowired
private UserService service;
@Override
public void newRevision(Object revisionEntity) {
BRAuditRevisionEntity customRevisionEntity = (BRAuditRevisionEntity) revisionEntity;
customRevisionEntity.setUsername(service.getAuthenticatedUser().getEmail());
}
}
Revinfo類：
@Entity
@Table(name = "revinfo")
@RevisionEntity(BRAuditEnversListener.class)
public class BRAuditRevisionEntity implements Serializable {
private static final long serialVersionUID = 1L;
@RevisionNumber
private int id;
@RevisionTimestamp
private long timestamp;
private String username;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@Transient
public Date getRevisionDate() {
return new Date(timestamp);
}
public long getTimestamp() {
return timestamp;
}
public void setTimestamp(long timestamp) {
this.timestamp = timestamp;
}
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (!(o instanceof DefaultRevisionEntity)) {
return false;
}
DefaultRevisionEntity that = (DefaultRevisionEntity) o;
if (id != that.getId()) {
return false;
}
if (timestamp != that.getTimestamp()) {
return false;
}
return true;
}
@Override
public int hashCode() {
int result;
result = id;
result = 31 * result + (int) (timestamp^(timestamp >>> 32));
return result;
}
@Override
public String toString() {
return "DefaultRevisionEntity(id = " + id + ", revisionDate = " + DateFormat.getDateTimeInstance().format(getRevisionDate()) + ")";
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
Web服務端點它調用插件的方法：
@Override
@RequestMapping(value = "/create", method = RequestMethod.POST)
public ResponseEntity<Local> create(@ApiParam(value = "Local json stream resource", required = true) @Valid @RequestBody Local local) {
Local created = service.insert(local);
if (null == created)
return new ResponseEntity<>(HttpStatus.NOT_MODIFIED);
return new ResponseEntity<Local>(created, HttpStatus.CREATED);
}
這是拋出了異常的方法：
@Transactional
@Override
public Local insert(Local local) {
return repository.save(local);
}
最後，異常（很短，順便說一句）：
2017-08-26 20:18:52.006 ERROR 2784 --- [nio-8080-exec-4] org.hibernate.AssertionFailure : HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): java.lang.NullPointerException
2017-08-26 20:18:52.009 WARN 2784 --- [nio-8080-exec-4] .m.m.a.ExceptionHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Error while committing the transaction
我需要配置一些特別的東西？也許添加一些註釋？任何關於我能做什麼的想法？
如何保存的實例還不清楚'Local'觸發審計事件（然後導致所述例外）。另外，對於正確的Spring Boot項目，POM文件太複雜了（例如，爲什麼包含啓動數據JPA和JPA API;它們已經由Spring Boot啓動器導入）。您應該先嚐試使用Spring Boot項目（在http://start.spring.io上創建一個）進行審計，而不引入任何與審計無關的依賴關係。當事情奏效時，逐漸添加其他作品。 – manish
謝謝@manish，我會檢查所有這些。奇怪的是（正如我所說）「我的系統工作得很好，直到我將@Audit包含在實體中。」和hibernate-envers當然是依賴關係。底線，你是否建議我排除我的.pom文件中的這些條目：' spring-boot-starter-data-jpa '和' hibernate-jpa-2.1-api '？ 順便說一下，我添加了在問題中調用插入的方法。 謝謝 –
我建議用'spring-boot-starter'和'hibernate-envers'依賴關係創建一個示例項目，並用它來測試審計需求。 – manish
