<!--xml文件-->

<?xml version="1.0" encoding="UTF-8"?>

<actions>

<action path="/chen" class="com.demo.testCHEN">

<forward name="success" url="xiao-chen"/>

<forward name="fail" url="da-chen"/>

</action>

<action path="/bei" class="com.demo.testBEI">

<forward name="success" url="xiao-bei"/>

<forward name="fail" url="da-bei"/>

</action>

</actions>

运行结果：

action.path--->/chen

action.class--->com.demo.testCHEN

forward.name--->success

forward.url--->xiao-chen

forward.name--->fail

forward.url--->da-chen

action.path--->/bei

action.class--->com.demo.testBEI

forward.name--->success

forward.url--->xiao-bei

forward.name--->fail

forward.url--->da-bei
