Answer 1

You are most likely trying to past argument as a String somewhere where it should not be accepting String as a parameter or could be not accepting any parameters at all.

As one of the comment said, can you post your codes here? The logs are not telling as well which of your specific class is having an exception.

Answer 2

I suspect you have some Spring MVC controllers and expect that Spring matches controller method arguments and request parameters by name automatically.

According to this article enter link description here this only works if your code has been compiled with debugging information (javac -g options).

I've also a hard time with this issue. It worked in my IDE, but not when deploying an ant build to a tomcat. When I tried to remote debug the tomcat and therefore added the javac debug options, it suddenly worked. However, i did not see the relation of the debug option and the issue I was looking for ;-)

Answer 3

实际上，这里 String 类型不可用，这意味着如果我们提供参数：@Requestparam(value = "myString") String myString 如果我们像 @Requestparam String myString 这样提供它，很可能会得到该错误。

Answer 4

We faced the same error when the method missed to add @RequestParam annotation against the string. The error is generated when we started to use the Ant Build through Jenkins. When export WAR file through Eclipse IDE, it will not arise.
