我有一个方法，如果此人具有特定的角色，并且他们与JIRA中的特定组相关联，则可以调用该方法。由于JIRA中的组是动态的，所以我不能为每个JIRA组分配一个角色。

@DeclareRoles({
  FileServerRoles.FILE_ADDER,
  FileServerRoles.FILE_ADDER_ALL,
  FileServerRoles.FILE_VIEWER,
  FileServerRoles.FILE_VIEWER_ALL})
public final class FileServerRoles {

  /**
   * A user that can add files to the system.
   */
  public static final String FILE_ADDER = "file-adder";
  /**
   * A user that can add any files to the system.
   */
  public static final String FILE_ADDER_ALL = "file-adder-all";
  /**
   * A user that can view files in the system.
   */
  public static final String FILE_VIEWER = "file-viewer";
  /**
   * A user that can view all files in the system.
   */
  public static final String FILE_VIEWER_ALL = "file-viewer-all";
}

我使用@DeclareRoles声明所有的角色。

@Decorator
public class FileServerServiceProjectAuthorizationDecorator implements FileServerService {

  private static Logger LOGGER = LoggerFactory.getLogger(FileServerServiceProjectAuthorizationDecorator.class);
  @Inject
  @Delegate
  @Any
  FileServerService delagate;
  @Inject
  @CurrentUser
  Set<JiraProjectReference> currentUserProjectReferences;
  @Resource
  SessionContext sessionContext;

  void verifyProjectKey(final String projectKey) {
    for (final JiraProjectReference projectReference : currentUserProjectReferences) {
      if (projectReference.getKey().equalsIgnoreCase(projectKey)) {
        return;
      }
    }
    throw new IllegalArgumentException("user not in the project");
  }

  @RolesAllowed({FileServerRoles.FILE_ADDER, FileServerRoles.FILE_ADDER_ALL})
  @Override
  public FileAddStatus addFileToRepository(final String projectKey, final String issueKey, final String fileName, final String mimeType, final File file) {
    if (!sessionContext.isCallerInRole(FileServerRoles.FILE_ADDER_ALL)) {
      verifyProjectKey(projectKey);
    }
    return delagate.addFileToRepository(projectKey, issueKey, fileName, mimeType, file);
  }

  @RolesAllowed({FileServerRoles.FILE_VIEWER, FileServerRoles.FILE_VIEWER_ALL})
  @Override
  public FileDescriptor retrieveFileFromRepository(final String projectKey, final String issueKey, final UUID uuid, final String fileName) {
    if (!sessionContext.isCallerInRole(FileServerRoles.FILE_VIEWER_ALL)) {
      verifyProjectKey(projectKey);
    }

    return delagate.retrieveFileFromRepository(projectKey, issueKey, uuid, fileName);
  }
}

!sessionContext.isCallerInRole(FileServerRoles.FILE_VIEWER_ALL)总是抛出IllegalStateException

Caused by: java.lang.IllegalStateException: No mapping available for role reference file-viewer-all
        at com.sun.ejb.containers.EJBContextImpl.isCallerInRole(EJBContextImpl.java:458)
        at edu.wvu.esd.swordfish.web.service.FileServerServiceProjectAuthorizationDecorator.retrieveFileFromRepository(FileServerServiceProjectAuthorizationDecorator.java:59)
        ... 89 more

当在@RolesAllowed中引用角色时，我对任何角色都没有任何问题。我还尝试将角色声明移动到web.xml中。在谷歌上没有太多关于这个错误的参考资料。

有没有人看过这个？您的解决方案是什么？

在EJB3.1中调用GlassFish中的isCallerInRole(roleName)方法时，我收到了相同的"No mapping available for role reference“错误。修复它的方法是向我的EJB添加适当的@DeclareRoles注释。如果传递给isCallerInRole的角色名不在@DeclareRoles中，则会抛出IllegalStateException。我不确定装饰器中的安全性是如何工作的，但@DeclareRoles对我来说是关键。

下面是一个简单的例子：

@Stateless
@LocalBean
@DeclareRoles({"user", "admin"})
public class ExampleEJB {
    @Resource
    private SessionContext sessionContext;

    public boolean isUserInRole(String roleName) {
        return sessionContext.isCallerInRole(roleName);
    }
}
