我正在尝试结合使用eclipselink(2.4.0)和spring-data-jpa(1.1.0.RELEASE)来实现一个解决方案。但是,每次部署解决方案(Tomcat 7)时,都会出现以下异常:
Caused by: java.lang.IllegalArgumentException: No [ManagedType] was found for
the key class [com.acme.domain.entities.User] in the Metamodel - please
verify that the [Managed] class was referenced in persistence.xml using a
specific <class>com.acme.domain.entities.User</class> property or a global
<exclude-unlisted-classes>false</exclude-unlisted-classes> element.
当存储库 Autowiring 发生时,它似乎发生了(下面的代码示例):
服务等级
@Component
public class UserDataService {
@Autowired
private UserRepository userRepository;
...
}
实体类
package com.acme.domain.entities;
...
@Entity
@Table(name = "users")
public class User implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "user_id")
private Integer id;
...
}
persistence.xml
<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.acme.domain.entities.User</class>
...
</persistence-unit>
这可能是由于spring和eclipselink之间的某些冲突造成的吗?

最佳答案
我能够解决我的问题,但这是上面的另一种设置,我只添加了偶然发现的几件事,直到能够在我的SE环境中解决它:
<exclude-unlisted-classes>false</exclude-unlisted-classes>
最后,当涉及到我的设置时(Spring-Standalone Application,没有persistence.xml,而是大量的Spring配置,因为使用了自定义公司Framework),这表明我只是忘了添加自定义Framework-Core的实体包当我想在本地项目中运行其服务实现之一(Spring-Bean实现)而不是从JAR依赖项获得其服务实现时。因此,请确保已为EntityManagerFactory列出了所有必需的实体包:
<bean id="customEntityManagerFactory" parent="abstractEntityManagerFactory">
<property name="dataSource" ref="dataSource"/>
<!-- Packages of EntityClasses -->
<property name="packagesToScan">
<list merge="true">
<value>ch.company.div1.foo.bar.model</value>
<value>ch.company.div1.foo.barnicle.model</value>
<value>ch.company.div2.we.help.model</value>
</list>
</property>
<property name="jpaProperties">
<props merge="true">
<prop key="eclipselink.target-database">org.eclipse.persistence.platform.database.SQLServerPlatform
</prop>
<prop key="javax.persistence.transactionType">RESOURCE_LOCAL</prop>
</props>
</property>
</bean>
在我的情况下,我忘记将模型封装与我们公司的另一个部门(写自定义框架核心)的使用过的实体一起添加。
祝你好运,那个错误是野兽:/
