为应用指定多个struts配置文件

在大部分应用里,随着应用规模的增加,系统中Action的数量也会大量增加,导致struts.xml配置文件变得非常臃肿。为了避免struts.xml文件过于庞大、臃肿,提高struts.xml文件的可读性,我们可以将一个struts.xml配置文件分解成多个配置文件,然后在struts.xml文件中包含其他配置文件。下面的struts.xml通过<include>元素指定多个配置文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<include file="struts-user.xml"/>
<include file="struts-order.xml"/>
</struts>

通过这种方式,我们就可以将Struts 2的Action按模块添加在多个配置文件中。

例如:

struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<include file="user.xml"/>
<include file="employee.xml"/>
</struts>

user.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="itcast" namespace="/test" extends="struts-default">
<action name="helloworld" class="com.liyong.action.UserAction" method="execute" >
<result name="success">/WEB-INF/page/hello.jsp</result>
<!-- 访问路径 http://localhost:8080/Structs2/test/helloworld -->
</action>
</package>
</struts>

employee.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="itcast" namespace="/test" extends="struts-default">
<action name="helloworld" class="com.liyong.action.EmployeeAction" method="execute" >
<result name="success">/WEB-INF/page/hello.jsp</result>
<!-- 访问路径 http://localhost:8080/Structs2/test/helloworld -->
</action>
</package>
</struts>
