struts2引文配置Action及拦截器几种不同方式写法对应的路径指向

struts2注解配置Action及拦截器几种不同方式写法对应的路径指向

本工程中：

Action类的类路径：com.xxx.xxx.main.action.LotteryAction 需要拦截器检查是否登录

??????????????????????????? com.xxx.xxx.main.action.ActivityAction 不需要拦截器

相关页面路径：WebRoot/page/lottery???? 和 WebRoot/page/activity

Struts.xml:

拦截器配置方式：（此部分讲拦截器配置，不用看Action方法注解上的value与results，这些在下面讲Action配置时会讲到，因为Action类声明上的注解与方法上的注解搭配不同，可以导致Action方法注解上的value与results中路径写法不同）

第一种方式，不按包拦截，拦截器配置到全局根包路径下，以具体的Action方式中引用为准

? ? ? <package name="crud-default" extends="convention-default">
??????? <interceptors>
??????????? <interceptor name="checkLogin" extends="crud-default">
??????? 
??????????? <!--<interceptor name="checkLogin" extends="convention-default">
??????? <!--<interceptors>
??????????? <interceptor name="checkLogin" extends="crud-default" namespace="/activity">
??????? <interceptors>
??????????? <interceptor name="checkLogin" extends="convention-default">
??????? <interceptors>
??????????? <interceptor name="checkLogin" extends="crud-default" namespace="/activity">
??????? <!--<interceptors>
??????????? <interceptor name="checkLogin" value="/"/>决定了convention插件去的起始寻找地址，这里配置的/即指向WebRoot，再加上解析出来的Namespace为lottery，所以去WebRoot/lottery/下去寻找页面，如果<constant name="struts.convention.result.path" value="/page"/>,则convention插件去的起始寻找地址为/WebRoot/page/再加上解析出来的Namespace为lottery，就会去WebRoot/page/lottery/去寻找页面，这样的话，location = "lotteryinfo.ftl"即可)

第二种方式：Action类声明中注解指定Namespace

A、action名中带/

@Controller("lotteryAction")
@Namespace("/lottery")
public class LotteryAction extends AbstratcBusiAction {

????? @org.apache.struts2.convention.annotation.Action(
??????????? value = "/showLotteryInfo",? 带/
??????????? results = {
??????????????????? @Result(name = "success", type = "freemarker", location = "/page/lottery/lotteryinfo.ftl"),
??????????????????? @Result(name = "fail", type = "freemarker", location = "/page/lottery/failedmessage.ftl")

??????????? })
??? public String showLotteryInfo() {...}

}

? 此种方式中value = "/showLotteryInfo"，location=的值将会以简单的字符串拼接形式组成，(除非location="/"开头的绝对地址)

????? location = "../page/lottery/lotteryinfo.ftl"，去向的地址将会是：WebRoot/lottery/../page/lottery/lotteryinfo.ftl，这是错误的（这是convention插件根据@Namespace("/lottery")解析出来的寻找页面起始为"WebRoot/lottery/"+"../page/lottery/lotteryinfo.ftl"）拼接而成。

????? location = "/page/lottery/lotteryinfo.ftl"，去向的地址将会是：WebRoot/page/lottery/lotteryinfo.ftl，这是正确的（因为location=/开头，表始绝对地址WebRoot，无论<constant name="struts.convention.result.path" value="/"/>还是<constant name="struts.convention.result.path" value="/page"/>,这个以/开头的 location = "/page/lottery/lotteryinfo.ftl"始终是指向WebRoot/page/lottery/lotteryinfo.ftl的）

总结： value = "/showLotteryInfo"这种action名中带/的方式，不会对location指向的一个由./或../开头的相对地址进行解析的，对location指向由/开头的，无论<constant name="struts.convention.result.path" value="？"/>，始终将/解析成WebRoot.

B、action名中不带/

@Controller("lotteryAction")
@Namespace("/lottery")
public class LotteryAction extends AbstratcBusiAction {

????? @org.apache.struts2.convention.annotation.Action(
??????????? value = "showLotteryInfo",? 不带/
??????????? results = {
??????????????????? @Result(name = "success", type = "freemarker", location = "/page/lottery/lotteryinfo.ftl"),
??????????????????? @Result(name = "fail", type = "freemarker", location = "/page/lottery/failedmessage.ftl")

??????????? })
??? public String showLotteryInfo() {...}

}

location = "../page/lottery/lotteryinfo.ftl"，去向的地址将会是：WebRoot/page/lottery/lotteryinfo.ftl，这是正确的（这是convention插件根据@Namespace("/lottery")解析出来的寻找页面起始为"WebRoot/lottery/"

这个地址的../也就是上一级目录下的page/lottery/lotteryinfo.ftl，此时的<constant name="struts.convention.result.path" value="/"/>；

如果此时的<constant name="struts.convention.result.path" value="/page"/>，则解析出来的寻找页面起始为WebRoot/page/lottery/,?? location = "../page/lottery/lotteryinfo.ftl"就会变成WebRoot/page/page/lottery/lotteryinfo.ftl，这是错误的，应同步修正成location = "lotteryinfo.ftl"即可，不能是location = "/lotteryinfo.ftl"（带上/就变成了WebRoot/lotteryinfo.ftl这个地址了）

总结：value = "showLotteryInfo"这种action名中不带/的方式，将会对location指向的一个由./或../开头的相对地址进行解析的，对location指向由/开头的，无论<constant name="struts.convention.result.path" value="？"/>，始终将/解析成WebRoot.
