struts2相关设置
1、复制commons-fileupload-1.2.1.jar,commons-io-1.3.2.jar,commons-logging-1.0.4.jar,freemarker-2.3.13.jar,ognl-2.6.11.jar,struts2-core-2.1.6.jar,xwork-2.1.2.jar到/WEB-INF/lib目录下。
2、在web.xml中添加
2、在web.xml中添加
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
3、在src目录中新建struts.xml文件,内容示例如下:
<?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="struts2" extends="struts-default">
<action name="login" class="com.test.action.LoginAction">
<result name="input">/login2.jsp</result>
<result name="success">/result.jsp</result>
</action>
</package>
</struts>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="struts2" extends="struts-default">
<action name="login" class="com.test.action.LoginAction">
<result name="input">/login2.jsp</result>
<result name="success">/result.jsp</result>
</action>
</package>
</struts>
4、标签库设置
在jsp文件前面加上<%@ taglib prefix="s" uri="/struts-tags"%>
5、XML校验设置
在需要校验的Action同目录中增加 Action名-validation.xml,如Action名为RegisterAction,则校验文件名为RegisterAction-validation.xml,示例如下
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
<field name="username">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
</field>
<field name="password">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
</field>
</validators>
"-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
<field name="username">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
</field>
<field name="password">
<field-validator type="requiredstring">
<message key="requiredstring"/>
</field-validator>
</field>
</validators>
