与PrettyFaces复制的映射ID [英] Duplicated mapping id with PrettyFaces

问题描述

我在 Spring Security 3 中使用了 PrettyFaces 3.3.0 我有两个 UserBean 豆，它们被映射为投放到页面(用户，添加) 和 LoginBean 来提供登录页面

i am using PrettyFaces 3.3.0 with Spring Security 3 i have two beans UserBean which is mapped to serve to pages (users,add) and LoginBean to serve the login page

我的映射如下:

1- UserBean:

1- UserBean:

@Component("user")
@Scope("request")
@URLMappings(mappings = {
        @URLMapping(id = "users", pattern = "/users", viewId = "/faces/users.xhtml"),
        @URLMapping(id = "add", pattern = "/add", viewId = "/faces/add.xhtml") })
public class UserBean {

2- LoginBean:

2- LoginBean:

@Component("login")
@Scope("request")
@URLMapping(id = "login", pattern = "/login", viewId = "/faces/login.xhtml")
public class LoginBean {

但是当我尝试运行该应用程序时 我收到以下异常(我在异常前后添加了一些调试):

but when i try to run the application i am getting the following exception (i added some debugs before and after the exception):

DEBUG [main] (FacesConfigBeanNameResolver.java:110) - Found 0 bean names in faces configuration.

DEBUG [main] (AbstractClassFinder.java:200) - Bytecode filter recommends to scan class: myapp.LoginBean

此行对LoginBean重复两次，这是问题吗?

this line is repeated twice for LoginBean, is it the problem ?

字节码过滤器建议扫描类LoginBean

请告知.

推荐答案

请确保您的IDE/构建工具未将重复的类文件放入Web应用程序输出目录中.这很可能是原因.我还相信，这个问题已经在PrettyFaces类扫描器中得到了解决，但是问题出在构建中.

Please make sure that your IDE/build tool is not putting duplicated class files into your web application output directory. This is most likely the cause. I also believe this issue has been addressed in the PrettyFaces class scanner, but the fault is in the build.
