Struts2 java.lang.NoSuchMethodException_问答_开发者

I have a problem with Struts2, in my ActionClass I declared an:

private Integer table; + setter and getter methods

then I have a form in my .jsp:

<s:form action="add-note" theme="simple">

            <s:select name="table" list="tablesList.{tableNr}" cssClass="tables" headerValue="-- Select table --" headerKey="-1"/>

</s:form>

But when I try to submit this form, I am getting a very strange exception:

Sorry for the stack trace;

I posted this same answer to another question earlier, but it could be relevant to this question also:

The NoSuchMethodException ... ([Ljava.lang.String;)] problem can be caused by having multiple attributes with the same name in the HTTP request.

If the case with multiple attributes with the same name is legitimate, you can handle multiple id values by changing setId(int id) to setId(String[] idArray) and parsing each array member string as an integer.

Make sure there is only one setId method (setId(String[] idArray)) in the action class. It seems some versions of struts/ognl (ognl 3.0.4?) can get confused if there are multiple methods with same name but different parameter types.

For example:

public void setId(String[] idArray) {
    for (String idString : idArray) {
       int id = Integer.parseInt(idString);
       ... handle different id values somehow ...
    }
}

<select> returns string value and you are trying to assign that value to an Integer variable table

Declare table as String (with getter/setter) and if you want to use its integer value then use the parseInt()method
