如何在ajax中调用Struts2 Action方法？

public class MyAction extends ActionSupport {
    public String execute() {
        // 执行逻辑
        return SUCCESS;
    }
}

<struts>
   <package name="example" extends="struts-default">
       <action name="myAction" class="com.example.MyAction">
           <result>/success.jsp</result>
        </action>
    </package>
</struts>

$.ajax({
    url: 'myAction.action',
    type: 'POST',
    dataType: 'json',
    success: function(response) {
        // 处理响应数据
    },
    error: function(xhr, textStatus, errorThrown) {
        // 处理错误
    }
});

success: function(response) {
    var jsonData = $.parseJSON(response);
    // 处理响应数据
}
