我正在使用 PrettyFaces 3.3.0 与 Spring Security 3 我有两个bean UserBean ,它被映射为服务于页面(用户,添加) 和 LoginBean 来提供登录页面
我的映射如下:
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:
@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 我得到以下异常(我在异常之前和之后添加了一些调试):
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
对于LoginBean,此行重复两次,这是问题吗?
字节码过滤器建议扫描类LoginBean
请告知。
答案 0 :(得分:1)
请确保您的IDE /构建工具没有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。我也相信这个问题已在PrettyFaces类扫描程序中得到解决,但错误在构建中。
