为什么JSON数据POST没有解析。我认为JSON格式是错误的。
请帮帮我。

为什么不接受json作为服务方法的字符串输入,然后使用Jackson或Gson将它们解析为java对象(在您的例子中是
PermissionGroupRequestCriteria
),这样,当错误的json被传递到服务时,您就能够处理这种情况。

json格式是可以的。您缺少的是TnPermission*类上的一组注释,这些注释将告诉您正在使用的JAX-RS实现(Jersey?)如何从JSON解析和分配数据。引发异常的行是:grp=userDelegate.addPermissionGroup(grp)?你能给我们完整的stacktrace吗?现在,你可以在问题中看到完整的stacktrace是stacktrace中的这一行(在com.*.ejb.UserManagerEJB.addPermissionGroup(UserManagerEJB.java:521))等于代码片段中的这一行(grp=userDelegate.addPermissionGroup(grp);)?我想,你是对的,两者都是相等的。
