定义filter，此处加载struts2过滤器。
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
定义web服务器通知项，即，符合“/*”的URL请求都交给命名为“struts2”的过滤器(即，org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter)处理。
<filter-mapping>
<filter-name>struts2</filter-name>

@Action/@Result：
@Action指定一个类为action，对应配置文件中的<action>....</action>标签，其中可以配置如下属性
1.results：配置返回的结果集属性，相当于struts2中的<result>列表，可以在{}中配置属性
2.value：配置action的名字，相当于<action>中的name属性
3.interceptorRefs：配置拦截器
@Action可以定义在类上，也可以定义在方法上
@Action(value = "testAction",results = {@Result(name="success",location="/success.jsp")})
public class testAction extends ActionSupport {
@Override
public String execute() throws Exception {
return SUCCESS;
}
}
public class AccidentSaleAction extends BaseAction {
@Action(value = "accidentPage", results = {
@Result(name = "paypage", location = "toPayPage", type = "chain"),
@Result(name = "accident/main", location = "accident/main.jsp") ,
@Result(name = "accident/quote", location = "accident/quote.jsp") ,
@Result(name = "accident/fillin", location = "accident/fillin.jsp"),
@Result(name = "accident/confirm", location = "accident/confirm.jsp"),
@Result(name = "fromError", location = "common/page/fromError.jsp")}
)
public String accidentPage() throws Exception {
// TODO 关闭核心接口 用于开发
if (!CommonConstant.isCoreServiceFunctional) {
logger.warn("警告：检测到已关闭核心接口调用，核心返回数据将采用随机生成策略！");
}
}
}
@Result实现跳转到另一个action
@ParentPackage(value="struts-default") @Action(value="studentAdd",results={ @Result(name="success",type="chain",location="studentList"), @Result(name="error",location="/usererror.jsp") })
chain 用于把相关的几个action连接起来，共同完成一个功能。处于chain中的action属于同一个http请求，共享一个ActionContext
另外补充：同一个action中 一个方法跳转至另一个方法 "user" 为该action的命名
@Result(name = "success", location = "user", type = "chain", params = { "method", "index" })
@Result/@Results：
@Result配置具体返回结果，在results中使用，也可以单独在类上使用，有如下属性
- name：对应<result>中的name属性
- location：对应<result></result>间的地址
- type：对应<result>的type属性
@Result可以在类上声明，也可以和Action配置声明，如果在类上声明，那么就是全局的结果，如下
@Result(name="delete",location = "/delete.jsp") public class testAction extends ActionSupport { @Action(value = "add", results = { @Result(name = "add", location = "/add.jsp") }) public String add() throws Exception { return "add"; } @Action(value = "delete") public String delete() throws Exception { return "delete"; } }
虽然delete方法没有指定返回delete时要跳转到哪个页面页面，但是在类上用@Result声明了，那么就会找到类上面的这个@Result，然后跳转到delete.jsp页面
@Results是用来声明多个结果集，用法和@Actions类似
