stacktrace告诉您出了什么问题：CongressBean.java类的第534行（在initCongressBean方法中）有一个nullpointerexception。您需要确定该行中的哪个引用为null及其原因。您的源代码可能与已部署的二进制文件不同步，因为该行无法抛出NPE：
languageConverter = new LanguageConverter();
请发布
initCongressBean534 languageConverter=new languageConverter（）公共语言转换器（）{map=new HashMap（）；}languageConverter = new LanguageConverter();
