1.首先创建index.jsp,主体一行代

<a href="${pageContext.request.contextPath}/hello">第一次使用strut2</a>

2.创建HelloAction

创建方法say,返回String

public String say(){
return "good";
}

3.配置web.xml,屏蔽所有请求

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

4.配置struts.文件xml

<package name="default" namespace="/" extends="struts-default">
    <action name="hello" class="cn.itcast.action.HelloAction"
            method="say">
        <result name="good">/hello.jsp</result>
    </action>
</package>

5.创建hello.jsp

<h1>hello struts</h1>

maven默认不编译src下面的 .xml文件，需要在pom.xml里面加上

<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
            </includes>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>
