@Path("/auth")
@Stateless
public class RestWs {

    @EJB 
    private UserService userService;

    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public void registerRest(Users u){
        Users users = new Users();
        users.setUsername(u.getUsername());
        users.setEmail(u.getEmail());
        users.setPassword(u.getUsername());
        userService.registerService(u);
    }

}

@Override
    public Users register(Users users) {
        em.persist(users);
        return users;
    }

@Entity
public class Users implements Serializable{

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)

    private Long id;
    private String username;
    private String email;
    private String password;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public String toString() {
        return "Users{" + "id=" + id + ", username=" + username + ", email=" + email + ", password=" + password + '}';
    }


}

我不知道为什么我不能为注册用户发布数据，我需要一些其他的东西，比如解析或者....请帮助我，谢谢

只是我需要添加交叉过滤器和所有工作很好

@Provider
public class CORSFilter implements ContainerResponseFilter{

    @Override
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext response) throws IOException {
        response.getHeaders().add("Access-Control-Allow-Origin", "*");
        response.getHeaders().add("Access-Control-Allow-Headers",
                      "origin, content-type, accept, authorization");
        response.getHeaders().add("Access-Control-Allow-Credentials", "true");
        response.getHeaders().add("Access-Control-Allow-Methods",
                      "GET, POST, PUT, DELETE, OPTIONS, HEAD");
    }

}

并且在web.xml中

<init-param>
          <param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
          <param-value>com.ress.CORSFilter</param-value>
        </init-param>

仅此而已
