我试图使用EntityGraph
获取一些Lazy集合在我的实体上
@Entity
@Table
......
@NamedEntityGraph(name = "getDetails", attributeNodes = { @NamedAttributeNode(value = "prices") })
@NamedNativeQuery(name = "MyTable.getData", query = "SELECT * FROM MyTable", resultClass = MyTable.class)
存储库
@Query(nativeQuery = true)
@EntityGraph(value = "getDetails", type = EntityGraphType.FETCH)
MyTable findData();
使用本机查询时,我得到了下一个异常
java.lang.ClassCastException:org.hibernate.internal.SQLQueryImpl无法强制转换为org.hibernate.internal.QueryImpl 在org.hibernate.jpa.internal.QueryImpl.list(QueryImpl.java:604) 在org.hibernate.jpa.internal.QueryImpl.getSingleResult(QueryImpl.java:529) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) 在org.springframework.orm.jpa.SharedEntityManagerCreator $ DeferredQueryInvocationHandler.invoke(SharedEntityManagerCreator.java:372) at com.sun.proxy。$ Proxy276.getSingleResult(Unknown Source) 在org.springframework.data.jpa.repository.query.JpaQueryExecution $ SingleEntityExecution.doExecute(JpaQueryExecution.java:206) 在org.springframework.data.jpa.repository.query.JpaQueryExecution.execute(JpaQueryExecution.java:78) 在org.springframework.data.jpa.repository.query.AbstractJpaQuery.doExecute(AbstractJpaQuery.java:102) 在org.springframework.data.jpa.repository.query.AbstractJpaQuery.execute(AbstractJpaQuery.java:92) at org.springframework.data.repository.core.support.RepositoryFactorySupport $ QueryExecutorMethodInterceptor.doInvoke(RepositoryFactorySupport.java:482) at org.springframework.data.repository.core.support.RepositoryFactorySupport $ QueryExecutorMethodInterceptor.invoke(RepositoryFactorySupport.java:460) 在org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) 在org.springframework.data.projection.DefaultMethodInvokingMethodInterceptor.invoke(DefaultMethodInvokingMethodInterceptor.java:61) 在org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) 在 ................................................. .... at org.apache.tomcat.util.threads.TaskThread $ WrappingRunnable.run(TaskThread.java:61) 在java.lang.Thread.run(Thread.java:745)
使用JPQL查询时一切正常。但我有一个很大的原生查询,这是非常痛苦的转换为JPQL。在这种情况下有谁知道解决方法?将不胜感激任何帮助。
