如果你有我感兴趣的想法。

Answer 1

java.lang.NoSuchMethodError: fr.la.juserright.metier.Ressource.(ILjava/lang/String;Ljava/lang/String;Ljava/lang/String;I)V

这意味着 fr.la.juserright.metier.Ressource 的以下构造函数当前运行时类路径中根本不存在该类。

public Ressource(int arg1, String arg2, String arg3, String arg4, int arg5) {}

但是到目前为止给出的代码似乎没有在任何地方使用该构造函数。两个new Resource()调用 ResourceDAO类使用 Ressource或 List<Ressource>作为第 5 个参数。

显然运行时类路径是脏的，你正在运行一个过时的版本 RessourceDAO一直，而 Ressource类已在运行时类路径中正确更新。

清理、重建、重新部署和重启。

请注意，此问题与 JSF 无关。底层异常不是来自 javax.faces包，但仅来自 java.lang包，这基本上表示基本的 Java 语言/运行时问题。
