Hibernate/Oracle/Spring：java.sql.SQLException：协议冲突

Question

您能帮帮我吗，当我尝试使用 Hibernate/Oracle 10.2 执行更新 hql 时，出现以下错误：

我使用的是 Java 1.6。

在我的 Maven 中：

<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.4.0</version>
</dependency>
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
</dependency>

例外：

Caused by: org.springframework.transaction.TransactionSystemException: Could not roll back JPA transaction;
Caused by: org.hibernate.TransactionException: rollback failed
Caused by: org.hibernate.TransactionException: unable to rollback against JDBC connection
Caused by: java.sql.SQLException: Protocol violation

谢谢。

我找到了解决方案。 我已经更改了我的代码，只是删除了级​​联属性：

@OneToMany(fetch = FetchType.LAZY, mappedBy = "scheduleRequest", cascade = CascadeType.ALL)
public Set<AdhocDetail> getAdhocDetails() {
return this.adhocDetails;
}

到：

@OneToMany(fetch = FetchType.LAZY, mappedBy = "scheduleRequest")
public Set<AdhocDetail> getAdhocDetails() {
return this.adhocDetails;
}

谢谢。
