解決了，return SUCCESS;相當于return “success”;
struts.xml改成<result name="success">/index.jsp</result>
HelloAction.java
package action;
import com.opensymphony.xwork2.ActionSupport;
public class HelloAction extends ActionSupport {
/**
*?
*/
private static final long serialVersionUID = 1L;
@Override
public String execute() throws Exception {
System.out.println("執行Action");
return SUCCESS;
}
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">
