生成xml:
<?xml version="1.0" encoding="UTF-8"?>
<actions><action path="/test" class="com.mystruts.demo.LoginAction"><forward name="success" url="hello.jsp"/><forward name="fail" url="fail.jsp"/></action><action path="/user" class="com.mystruts.demo.UserAction"><forward name="success" url="list.jsp"/><forward name="fail" url="fail.jsp"/></action></actions>
