问题：

为什么对@RequiresUser的请求没有重定向到登录页面？

别兴国
2023-03-14

设置如下：嵌入式Jetty 9.3.0.M0运行一个GuiceServlet 3.0，它反过来使用Jersey 1.18.1进行映射和它可以做的所有其他漂亮的事情。Shiro 1.2.3被添加到此设置中以提供安全性。在一般情况下配置Shiro和ShiroWebModule中的FilterChain时，设置工作正常。

当使用Shiro的AOP特性用Shiro的注释来注释我的方法时，对被注释方法的URL的请求不会被重定向到登录页面。相反，Jersey的ContainerResponse会抛出org . Apache . Shiro . authz . un authenticated exception异常:

ERROR com.sun.jersey.spi.container.ContainerResponse -

浏览器显示一个＜code＞javax.servlet。ServletException:筛选的请求失败。。

然而，实现并绑定了相应的Jersey ExceptionMapper：

/* other imports omitted for readability */
import org.apache.shiro.authz.UnauthenticatedException;

public  class UnauthenticatedExceptionHandler
                implements ExceptionMapper<UnauthenticatedException>{

  public Response toResponse(UnauthenticatedException exception) {      
    return Response.status(Status.FORBIDDEN).type(MediaType.TEXT_PLAIN)
            .entity("Authorization required").build();
  }
}

因此，即使Shiro没有将请求重定向到登录页面，ExceptionMapper也应该触发，但它没有。< code>NotFoundException等工作的绑定异常映射。

必要的MethodInterceptors在一个模块中定义和绑定，该模块安装在我的“主”模块中:

/* imports ommitted for readability */
public class ShiroMethodInterceptorModule extends AbstractModule {

@Override
protected void configure() {
    bindInterceptor(Matchers.any(), Matchers.annotatedWith(RequiresRoles.class),
            new ShiroMethodInterceptor(new RoleAnnotationMethodInterceptor()));
    bindInterceptor(Matchers.any(), Matchers.annotatedWith(RequiresUser.class),
            new ShiroMethodInterceptor(new UserAnnotationMethodInterceptor()));
    bindInterceptor(Matchers.any(), Matchers.annotatedWith(RequiresPermissions.class),
            new ShiroMethodInterceptor(new PermissionAnnotationMethodInterceptor()));
    bindInterceptor(Matchers.any(), Matchers.annotatedWith(RequiresGuest.class),
            new ShiroMethodInterceptor(new GuestAnnotationMethodInterceptor()));
    bindInterceptor(Matchers.any(), Matchers.annotatedWith(RequiresAuthentication.class),
            new ShiroMethodInterceptor(new AuthenticatedAnnotationMethodInterceptor()));
  }

}

ShiroMethodInterceptor（无耻地抄袭@pabiagioli的“shiro guice jersey bootstrap”项目）的实现如下：

public class ShiroMethodInterceptor implements MethodInterceptor{

static final Logger logger = Logger.getLogger(ShiroMethodInterceptor.class.getName());

private org.apache.shiro.aop.MethodInterceptor methodInterceptor;

public ShiroMethodInterceptor(org.apache.shiro.aop.MethodInterceptor methodInterceptor) {
    this.methodInterceptor = methodInterceptor;
}


  public Object invoke(MethodInvocation methodInvocation) throws Throwable {
    return methodInterceptor.invoke(new ShiroMethodInvocation(methodInvocation));
  }

  private static class ShiroMethodInvocation implements org.apache.shiro.aop.MethodInvocation {

    private final MethodInvocation methodInvocation;

    public ShiroMethodInvocation(MethodInvocation methodInvocation) {
        this.methodInvocation = methodInvocation;
    }

    public Object proceed() throws Throwable {
        return methodInvocation.proceed();
    }

    public Method getMethod() {
        return methodInvocation.getMethod();
    }

    public Object[] getArguments() {
        return methodInvocation.getArguments();
    }

    public Object getThis() {
        return methodInvocation.getThis();
    }
  }
}

该项目是使用 maven 构建的，定义的相关依赖项包括：

  • 球衣-吉斯 1.18.1
    • guice 3.0
    • guice-servlet 3.0
    • 球衣-servlet 1.18.1

    编辑：为了完整：Realm是由相应的提供商创建的，ShiroWebModule的配置方法如下所示：

    protected void configureShiroWeb() {

    bindConstant().annotatedWith(Names.named("shiro.loginUrl"))
            .to("/login");

    addFilterChain("/", ANON);

    addFilterChain("/login", AUTHC);
    addFilterChain("/logout", LOGOUT);

    /* The following rule is activated when not using AOP
     * annotations
     * addFilterChain("/**", AUTHC);
     */

}

    我真的非常感谢任何指点。请不要犹豫，询问更多信息。

    编辑2:这可能是不相关的，但我在这里添加它是为了完整。进一步研究这个问题，我注意到，如果给出了错误的或空的凭证，即使我在ShiroWebModule中完全配置了Shiro并完全禁用了annotations和AOP，就我所见，会抛出一个运行时异常Exception，它由jersey捕获并打包到WebApplicationException中:

基于注释的授权断言逻辑当前不是 Web 感知的。您有 2 种选择：

  1. 配置您选择的web框架，以便在异常冒泡时捕获异常并按预期重定向，或
  2. 使用Shiro的基于servlet过滤器的断言框架（如您所配置的）

为了使这种工作体验更加“开箱即用”,需要修改Shiro servlet过滤器实现，以便在已知的Shiro异常出现时捕捉它们，并将最终用户重定向到一个已知的位置——请打开一个吉拉问题来捕获这项工作。HTH！

这实际上是authc过滤器的一个常见错误。它需要被配置为过滤你所有的网址，否则他们就无法使用。试试这个:
