I use Struts 2.3.32 and this is the code.
methodPrefix.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<s:textfield name="name"/>
<br><br>
<s:submit value="Create Person"/>
<s:submit name="method:cancel" value="Cancel"/>
</s:form>
</body>
</html>
MethodPrefixAction.java
public class MethodPrefixAction
{
private String name;
private String message;
public String execute() throws Exception
{
message = name + " create";
return "success";
}
public String cancel() throws Exception
{
message = "cancel";
return "success";
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">

when I push Cancel button, It do not call cancel() method, just call execute() method.
I don't know why method: prefix not work.
I searched a lot, and I know method: prefix configuration is false by default in Struts 2.3.32, so I used a constant..... but it did not work
This constant
works only for
action:prefix, not amethod:prefix. So you should use theactionattribute to submit tag.Note: If you have DMI turned off the
action:prefix is still available.
