2, the relevant code

struts.xml relevant code portion

<package name="default" namespace="/" extends="struts-default">
        <action name="helloworld_*" method="{1}" class="com.icheny.action.HelloWorldAction">
            <result>/result.jsp</result>
            <result name="add">/{1}.jsp</result>
            <result name="update">/{1}.jsp</result>
        </action>
</package>

HelloWorldAction.java relevant code portion

    public String add()
    {
        return "add";
    }

    public String update()
    {
        return "update";
    }

 

3 reasons

　　Since struts2 2.5 version of safety to the next level, prohibit the use of wildcards, all unsecured access must be allowed to be declared in struts.xml. I use the 2.5.16 version of the struts, and therefore the emergence of this mistake.

 

4. Solution

　　Add attributes in the package: strict-method-invocation = "false"

　　struts.xml package part of the code after modification of:

<package name="default" namespace="/" extends="struts-default" strict-method-invocation="false">
        <action name="helloworld_*" method="{1}" class="com.icheny.action.HelloWorldAction">
            <result>/result.jsp</result>
            <result name="add">/{1}.jsp</result>
            <result name="update">/{1}.jsp</result>
        </action>
</package>
