JBoss 7.1 上的 Rest 项目运行出错

Question

我在 JBoss 7.1 上创建了一个 REST 项目。我给你需要的类:

User.java

@XmlRootElement(name = "user")
public class User implements Serializable {
   private static final long serialVersionUID = 1L;
   private int id;
   private String name;
   private String profession;

   public User(){}

   public User(int id, String name, String profession){
        this.id = id;
    this.name = name;
    this.profession = profession;
   }

   public int getId() {
      return id;
   }
   @XmlElement
   public void setId(int id) {
      this.id = id;
   }
   public String getName() {
      return name;
   }
   @XmlElement
      public void setName(String name) {
      this.name = name;
   }
   public String getProfession() {
      return profession;
   }
   @XmlElement
   public void setProfession(String profession) {
      this.profession = profession;
   }
}

ListBean.java

@ManagedBean
@ViewScoped
public class ListBean {
    private static Client client;
    private static String REST_SERVICE_URL = "http://localhost:8080/UserManagement/rest/UserService/users";
    private static final String SUCCESS_RESULT="<result>success</result>";
    private static final String PASS = "pass";
    private static final String FAIL = "fail";
        private List<User> users;
    private transient DataModel<User> model;
    private User user;
    private int id;
    private String name;
    private String profession;

        private void init(){ 
           this.client = ClientBuilder.newClient();
        }

    @PostConstruct
    public void initialize()
    {
            ListBean tester = new ListBean();
        tester.init();
        GenericType<List<User>> list = new GenericType<List<User>>() {};
            users = client.target(REST_SERVICE_URL)
                  .request(MediaType.APPLICATION_XML)
                  .get(list);
            String result = PASS;
        if(users.isEmpty()){   
           result = FAIL;
        }
        List<User> lus = new ArrayList<User>();
        for(User u : users){   
           lus.add(u);
        }
    user = new User();
    }
 }

UserService.java

@Path("/UserService")
public class UserService
{   
   UserDao userDao = new UserDao();
   private static final String SUCCESS_RESULT="<result>success</result>";
   private static final String FAILURE_RESULT="<result>failure</result>";

   @GET
   @Path("/users")
   @Produces(MediaType.APPLICATION_XML)
   public List<User> getUsers(){
      return userDao.getAllUsers();
   }
 }

在运行之后，出现如下异常：

这个项目在 Tomcat6 和 7 上运行良好，但是 JBoss7.1 有问题。

Answer 1

所以相关的异常是这样的：

JBAS011232: Only one JAX-RS Application Class allowed

感谢：

@eis 的帮助通过展示这个激励 link Deploying a Jersey webapp on Jboss AS 7
线程Deploying a Jersey webapp on Jboss AS 7，此异常已解决。

然后，我遇到了这个问题：

java.lang.NoSuchMethodError: javax.ws.rs.core.MultivaluedMap.addAll(Ljava/lang/Object;[Ljava/lang/Object;)V

解决：

我做了一些类implements Serializable.
我在 META-INF 下添加了文件 jboss-deployment-structure.xml:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <!-- Exclude RestEasy conflict -->
            <module name="javaee.api" />
            <module name="javax.ws.rs.api"/>
            <module name="org.jboss.resteasy.resteasy-jaxrs" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

因此，我的项目也能正常工作。
