struts使用json返回类型是报找不到action的错
struts配置文件：
<package name="resourse" extends="json-default" >
<action name="addResourse" class="uploadResourseAction">
<result type="json">
</result>

</action>
</package>
action类：
@Component("uploadResourseAction")@Scope("prototype")
public class UploadResourseAction extends ActionSupport implements SessionAware {
private UploadResourseService uploadResourseService;
private List<ResourseCategory> resourseCategories;
private List<ResourseForum> resourseForums;
private List<ResourseType> resourseTypes;
private ResourseCategory resourseCategory;
private ResourseList resourseList;
//获取资源类型,所属分类
public String showResourseAllType(){
resourseCategories = uploadResourseService.getResourseCategories();
resourseForums = uploadResourseService.getResourseForums(resourseCategory);
resourseTypes = uploadResourseService.getResourseTypes();
return "success";
}


jsp页面：
function upRecource(){
document.getElementById("fistNumFrom").action="addResourse!showResourseAllType";document.getElementById("fistNumFrom").submit();
}

运行报的错误信息：
Struts has detected an unhandled exception:

Messages: There is no Action mapped for namespace [/] and action name [addResourse] associated with context path [/ipfcs].

<constant name="struts.enable.DynamicMethodInvocation" value="false" />
这句你把false改成true试试看，你把动态方法调用关了用addResourse!showResourseAllType貌似不行
