java.lang.NoSuchMethodException: No such accessible method: addForwardConfig() o

 

经常有人在配置Struts1.2的struts-config.xml配置文件时，配置错误，

 

错误的配置方式：

<!-- HelloWolrdAction配置 -->
<action path="/helloWorldAction" name="HelloWorldTestAction" className="pack.java.action.HelloWorldAction" input="/error.jsp" scope="request" parameter="p" >
<forward name="success" path="/main.jsp"></forward>
<forward name="failure" path="/index.jsp" redirect="true"></forward>
</action>

 

 

正确的配置方式:

 

 

<!-- HelloWolrdAction配置 -->
<action path="/helloWorldAction" name="HelloWorldTestAction" type="pack.java.action.HelloWorldAction" input="/error.jsp" scope="request" parameter="p" >
<forward name="success" path="/main.jsp"></forward>
<forward name="failure" path="/index.jsp" redirect="true"></forward>
</action>

 

 

注意className和type的区别。

 

错误信息：
