我有以下测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
    "classpath:ApplicationContext.xml",
    "classpath:SecurityContext.xml"
})
public class CompoundServiceSecurityTest {

    @Autowired
    @Qualifier("testCompoundService")
    private TestCompoundService testCompoundService;

    //...
}

在这个类中， testCompoundService 被正确地自动装配并工作（如果实际问题是“禁用”的）。安全上下文包含以下自定义类：

<bean id="testCompoundPermission"
      class="myPackage.TestCompoundPermission">
</bean>

并且该类包含自动装配的 testCompoundService：

public class TestCompoundPermission extends AbstractPermission {

    @Autowired
    @Qualifier("testCompoundService")
    private TestCompoundService testCompoundService;

    //...
}

问题是 @Autowired testCompoundService因依赖 testCompoundService 本身而TestCompoundPermission失败。依赖于 StructureService，后者依赖于 StructureRepository（由 Spring Data 生成）。例外是：NoSuchBeanDefinitionExceptionTestCompoundService

NoSuchBeanDefinitionException: No matching bean of type myApp.repository.StructureRepository found

如果我@Autowired在TestCompoundPermission应用程序上下文中正确加载评论（当然，一些测试会因 NullPointerException 而失败，因为 testCompoundService 为空）。

这很奇怪，因为显然在测试类上加载完全正常的 bean 工作得非常好。为了完整起见，我还尝试使用构造函数参数并删除了@Autowired。结果相同。对我来说，看起来 2 个上下文是完全分离的，因此安全上下文无法从应用程序上下文访问 bean。我该如何解决这个问题？

发现这个：

http://forum.springsource.org/showthread.php?113720-No-matching-bean-when-using-custom-PermissionEvaluator-and-Spring-Data-JPA

这正是我遇到的问题。但是，解决方法不起作用，因为<jpa:repository />它不再是有效元素。

加载配置文件不是问题

这是您在 xml 文件中定义的bean 及其属性的问题。

检查.xml 文件是否提供了正确的 bean 引用及其在测试类中使用的属性引用。

例如。）

testCompoundService Bean必须在您调用的任何 .XML 中定义

事实证明，这是 Spring 数据的普遍问题。
