Answer 1

您最有可能尝试将参数作为字符串传递给某个地方，在该地方，该参数不应接受字符串作为参数，也可能根本不接受任何参数。

正如评论之一所说，您可以在此处发布代码吗？日志也无法告诉您哪个特定班级有例外。

Answer 2

我怀疑您有一些Spring MVC控制器，希望Spring会自动匹配控制器方法参数并按名称请求参数。

根据本文enter link description here，仅当您的代码已使用调试信息（javac -g选项）进行编译时，此方法才有效。

我在这个问题上也很难受。它在我的IDE中有效，但在将ant构建部署到tomcat时无效。当我尝试远程调试tomcat并因此添加javac调试选项时，它突然工作了。但是，我没有看到调试选项与我正在寻找的问题的关系;-）

Answer 3

实际上，这里的String类型不可用，这意味着就像我们提供参数一样： @Requestparam（value =“ myString”）字符串myString 如果我们给它类似@Requestparam String myString，则很可能会收到该错误。

Answer 4

当该方法未针对字符串添加@RequestParam批注时，我们遇到了相同的错误。当我们开始通过Jenkins使用Ant Build时，会生成该错误。通过Eclipse IDE导出WAR文件时，不会出现。
