java - struts2约定插件在EAR中不起作用，但在WAR中可以正常工作

当我部署WAR文件时，约定插件能够使用注释找到动作类，但是无法在EAR中找到动作。


glassfish- v2.1.1
struts2-convention-plugin-2.3.15.3


struts.xml文件的内容：

<struts>
    <constant name="struts.devMode" value="true" />
    <constant name="struts.convention.action.mapAllMatches" value="true"/>
    <constant name="struts.convention.package.locators" value="webservice"/>
    <constant name="struts.convention.action.suffix" value="Controller"/>
    <constant name="struts.convention.default.parent.package" value="rest-default"/>

    <constant name="struts.convention.exclude.parentClassLoader" value="true" />
    <constant name="struts.convention.action.fileProtocols" value="jar,zip" />

    <constant name="struts.convention.action.includeJars" value=".*?/*.*?jar(!/)?"/>

动作类：

package com.kw.service.webservice;

import java.util.Collection;

import org.apache.struts2.rest.DefaultHttpHeaders;
import org.apache.struts2.rest.HttpHeaders;
import org.apache.struts2.convention.annotation.Results;
import org.apache.struts2.convention.annotation.Result;

import com.opensymphony.xwork2.ModelDriven;
import com.opensymphony.xwork2.Validateable;
import com.opensymphony.xwork2.ValidationAwareSupport;
import org.apache.struts2.convention.annotation.Namespace;

@Results({
    @Result(name="success", type="redirectAction", params = {"actionName" , "orders"})
})
public class OrdersController extends ValidationAwareSupport implements ModelDriven<Object>,  Validateable{

private Order model = new Order();
private String id;
private Collection<Order> list;
private OrdersService ordersService = new OrdersService();

// GET /orders/1
public HttpHeaders show() {
    return new DefaultHttpHeaders("show");
}

// GET /orders
public HttpHeaders index() {
    list = ordersService.getAll();
    return new DefaultHttpHeaders("index")
        .disableCaching();
}
}

最佳答案

我必须将以下字段显式设置为false。

  <constant name="struts.convention.exclude.parentClassLoader" value="false" />
