如果我不添加以下注释行，我有以下 jax-rs Restful API 可以正常工作

@RolesAllowed("AdminRole")

以上 GET 注解

package service;

import entities.Booking;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.ws.rs.Consumes;
import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.annotation.security.PermitAll;
import javax.annotation.security.RolesAllowed;
import javax.annotation.security.DeclareRoles;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;


@PermitAll
@Stateless
@Path("entities.booking")
public class BookingFacadeREST extends AbstractFacade<Booking> {
    @PersistenceContext(unitName = "ofserverDBPU")

    private EntityManager em;

    public BookingFacadeREST() {
        super(Booking.class);
    }

    @POST
    @Override
    @Consumes({"application/xml", "application/json"})
    public void create(Booking entity) {
        super.create(entity);
    }

    @PUT
    @Override
    @Consumes({"application/xml", "application/json"})
    public void edit(Booking entity) {
        super.edit(entity);
    }

    @DELETE
    @Path("{id}")
    public void remove(@PathParam("id") Integer id) {
        super.remove(super.find(id));
    }

    @GET
    @Path("{id}")
    @Produces({"application/xml", "application/json"})
    public Booking find(@PathParam("id") Integer id) {
        return super.find(id);
    }

    @RolesAllowed("AdminRole")
    @GET
    @Override
    @Produces({"application/xml", "application/json"})        
    public List<Booking> findAll() {
        return super.findAll();
    }

    @GET
    @Path("{from}/{to}")
    @Produces({"application/xml", "application/json"})
    public List<Booking> findRange(@PathParam("from") Integer from, @PathParam("to") Integer to) {
        return super.findRange(new int[]{from, to});
    }

    @GET
    @Path("count")
    @Produces("text/plain")
    public String countREST() {
        return String.valueOf(super.count());
    }

    @Override
    protected EntityManager getEntityManager() {
        return em;
    }

}

通过放置上面的注释给出以下错误。

HTTP Status 500 - Internal Server Error

type Exception report

我在哪里做错了？

它有点老了，但我仍然有同样的问题（注意我也有一个自定义的SecurityContext. 徘徊了一段时间后，我终于通过编写自己的“@RolesAllowed注释”来实现它。

这是我如何进行的：

首先，新建一个注解：

@NameBinding
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE})
public @interface Secured {
    String role() default "all";
}

然后，在身份验证阶段使用ContainerRequestFilter运行并检查权限：

@Provider
@Priority(Priorities.AUTHENTICATION)
public class SecurityFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

     @Override
     public void filter(ContainerRequestContext crc) throws IOException {
         // get annotation (only for secured method)
        Secured security = resourceInfo.getResourceMethod().getAnnotation(Secured.class);
        if(security == null){
            // no security on method: check the class 
            security = resourceInfo.getResourceClass().getAnnotation(Secured.class);
            if(security == null) return;
        }

        // check the security, for example through the header:
        //   crc.getHeaderString("token") 
        // You can also inject a PersistenceContext and query your db

        // if the security check fails, use crc.abort() method
        // else, set the security context
        crc.setSecurityContext(new AppSecurityContext(userId, security.role()));
     }
 }

此过滤器必须通过web.xml或使用构造函数中的register方法注册Application。

对于AppSecurityContext，看看这个教程。稍后可以通过以下方式在您的服务中访问它：

@Context
SecurityContext sctx;

最后，使用 . 注释您的类或方法（或两者）@Secure(role = "somerole")。
