在JUnit Jupiter中使用自定义组合注释时，为@Autowired bean获取NPE

Question

TransactionalIntegrationTest.java

    <configuration>
      <system.webServer>

            </rule>

            <!-- All other URLs are mapped to the node.js site entry point -->
            <rule name="DynamicContent">

          </rules>
        </rewrite>

        <!-- 'bin' directory has no special meaning in node.js and apps can be placed in it -->
        <security>
          <requestFiltering>
            <hiddenSegments>
              <remove segment="bin"/>
            </hiddenSegments>

MyTestTest .java

@TestMethodOrder(OrderAnnotation.class)
@SpringJUnitWebConfig(locations = { "classpath:service.xml","classpath:data.xml" })
@Tag("1")
public @interface TransactionalIntegrationTest {}

在@TransactionalIntegrationTest public class MyTestTest { @Autowired protected CreateUser createUser; @BeforeEach public void setUp() throws Exception { createUser.createTimesheetUser(...)} --> NPE } 上获取NullPointerException。

如果我不使用元注释，那么它将正常工作。

MyTestTest.java

createUser

Answer 1

您可能会缺少@Retention声明，该声明允许诸如Spring和JUnit之类的框架在运行时查看注释。

按如下所示声明组成的注解应该起作用。

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@TestMethodOrder(OrderAnnotation.class)
@SpringJUnitWebConfig(locations = { "classpath:service.xml", "classpath:data.xml" })
@Tag("1")
public @interface TransactionalIntegrationTest {
}
