JUINT 测试给出错误 java.lang.reflect.InaccessibleObjectException: Unable to make protected void java.lang.Object.finalize()

问题描述 投票：0回答：4

在运行测试时出现错误，我无法理解为什么会出现此错误，此代码在 Java 8 中运行良好，而在 Java 17 中运行时出现错误。用谷歌搜索这个错误，但没有发现任何有用的东西。请帮助我理解这个错误。 提前致谢:)

@RunWith(PowerMockRunner.class)
@PrepareForTest({PopulatedAuthorizedUser.class})
@SpringBootTest(classes = MockServletContext.class)
@PowerMockIgnore({"javax.management.*", "javax.net.ssl.*", 
"jdk.internal.reflect.*"})
public class ProjectUserControllerTest {

private ProjectUserController controller;

private UUID projectId = UUID.randomUUID();
private UUID groupId = UUID.randomUUID();
private String email = "[email protected]";

@Mock
private ProjectUserService projectUserService;

private ObjectMapper objectMapper = new ObjectMapper();

@Mock
protected AuthorizedUser au;

@Before
public void setUp() throws Exception {
    controller = new ProjectUserController();
    FieldUtils.writeField(controller, "projectUserService", projectUserService, true);
    FieldUtils.writeField(controller, "objectMapper", objectMapper, true);
    PowerMockito.mockStatic(PopulatedAuthorizedUser.class);
    Mockito.when(PopulatedAuthorizedUser.get()).thenReturn(mockAuthorizedUser());
}

@Test
public void testGetProjectUsers() {
    Mockito.doReturn(Arrays.asList(mockProjectUser())).when(projectUserService)
            .findProjectUsersByProjectId(projectId);
    Mockito.doNothing().when(projectUserService).enrichUserDetails(any(ProjectUserDto.class));
    ResponseEntity<List<ProjectUserDto>> response=controller.getProjectUsers(projectId);
    assertNotNull(response);
    ProjectUserDto projectUserDto = response.getBody().get(0);
    assertEquals(groupId, projectUserDto.getGroupId());
    assertEquals(email, projectUserDto.getUsername());
    assertTrue(projectUserDto.getEmailNotification());
    assertEquals(ProjectUserRole.OWNER.toString(), projectUserDto.getRole());
   }

 }

在 Java 9 及更高版本中，模块系统可能会导致这些错误。我在 JUnit 5 本身也有同样的问题，因为我从我的测试类和方法中省略了

public
。

这是我的 POM 中用来解决这个问题的内容：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <!-- Allow JUnit to access the test classes -->
    <argLine>--add-opens <my-module>/<my-package>=ALL-UNNAMED</argLine>
  </configuration>
</plugin>

在你的情况下你可能需要使用

java.base/java.lang=ALL_UNNAMED
.

按如下方式启动 JVM：

# --add-opens has the following syntax: {A}/{package}={B}
java --add-opens java.base/java.lang=ALL-UNNAMED

How to solve InaccessibleObjectException ("Unable to make {member} accessible: module {A} does not 'opens {package}' to {B}") on Java 9?

卸载 openjdk 19 为我解决了这个错误。

$ brew uninstall maven openjdk@19
$ brew install --ignore-dependencies maven

在 IntelliJ 中，我转到“编辑配置”以打开运行/调试配置，在那里我明确指定“Java8”作为我的版本。
