我正在运行WebSphere v8,并在Java EE 6环境中使用JPA持久性。
当我尝试运行处理特定实体的代码时,我遇到了这个异常:
javax.ejb.EJBTransactionRolledbackException:嵌套异常是:javax.ejb.EJBTransactionRolledbackException:嵌套异常是:javax.ejb.EJBException:参见嵌套异常;嵌套异常是:org.apache.openjpa.persistence.ArgumentException:“class au.com.combined.domain.changeroutine.ChangeRoutineConsumedPK”类型尚未得到增强。
但是,this article表示我的类应该已经在运行时得到增强。 ChangeRoutineConsumedPK是一个可嵌入的类。有人可以看看我的班级并告诉我我做错了什么吗?谢谢。
ChangeRoutineConsumed:
@Entity
@Table(name = ChangeRoutineConsumed.TABLE_NAME)
public class ChangeRoutineConsumed extends BaseBusinessObject {
public static final String TABLE_NAME = "COCHANGEROUTINECONSUMED";
@EmbeddedId
private ChangeRoutineConsumedPK id;
protected ChangeRoutineConsumed() {
super();
}
public ChangeRoutineConsumed(@Min(1) long changeRoutineId, @NotNull String consumedBy){
this(new ChangeRoutineConsumedPK(changeRoutineId, consumedBy));
}
public ChangeRoutineConsumed(@NotNull ChangeRoutineConsumedPK id){
super();
setId(id);
}
...
public int hashCode(){...};
public boolean equals(Object obj){...}
}
ChangeRoutineConsumedPK:
@Embeddable
public class ChangeRoutineConsumedPK {
@Column
private long changeRoutineId;
@Column
private String consumedBy;
public ChangeRoutineConsumedPK(){}
public ChangeRoutineConsumedPK(long changeRoutineId, String consumedBy) {
setChangeRoutineId(changeRoutineId);
setConsumedBy(consumedBy);
}
...
public int hashCode() {...}
public boolean equals(Object obj) {...}
}

ChangeRoutineConsumedPK类未添加到persistence.xml中,我已关闭自动类扫描。
将类添加到persistence.xml修复了问题
<persistence-unit ...>
...
<class>au.com.combined.domain.changeroutine.ChangeRoutineConsumedPK</class>
...
</persistence-unit>

如果你在执行中从主类传递下面的参数执行 java -javaagent:/openjpa.jar com.xyz.Main
如果在运行配置&gt;中使用eclipse给出上述值参数&gt; VM参数。
