struts终极解决方案

1.在struts2-core-2.3.14.jar包中路径为struts2-core-2.3.16\org\apache \struts2
有一个default.properties 文件,把struts.i18n.encoding=UTF-8改为

struts.i18n.encoding=GBK

2.或者在struts.xml文件内添加常量:

<constantname="struts.i18n.encoding" value="GBK"/>

我当然是用的第二种方法，简单方便．

<?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>
<constant name="struts.i18n.encoding" value="GBK"/>
<package name="com" extends="struts-default">
<action name="test" class="com.TestAction" method="test">
<result>/ok.jsp</result>
</action>
</package>
</struts>

3.以上方法不行可以选择spring过滤器 jar 包 spring-core-3.0.5.RELEASE   ，spring-web-3.0.5.RELEASE，spring-beans-3.0.5.RELEASE

web.xml配置如下

<filter>
<filter-name>encodingFilter </filter-name>
<filter-class>
org.springframework.web.filter.CharacterEncodingFilter
</filter-class>
<init-param>
<param-name>encoding </param-name>
<param-value>UTF-8 </param-value>
</init-param>
<init-param>
<param-name>forceEncoding </param-name>
<param-value>true </param-value>
</init-param>
</filter>

并将对应的后缀加入filter-mapping,例如
<filter-mapping>
<filter-name>encodingFilter </filter-name>
<url-pattern>*.do </url-pattern>
</filter-mapping>

千万要注意他们了的先后顺序，顺序颠倒了就不管用了哦
