struts彻底解决中文乱码问题的过滤器

package filter;

import java.io.UnsupportedEncodingException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.RequestProcessor;

public class CharFilter extends RequestProcessor {

@Override
protected boolean processPreprocess(HttpServletRequest request, HttpServletResponse response) {
// TODO Auto-generated method stub
try {
request.setCharacterEncoding("gbk");
response.setCharacterEncoding("gbk");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return true;

}

}

在struts-config.xml中的配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>
<data-sources />
<form-beans>
<form-bean name="UserForm" type="com.inspur.view.UserForm"></form-bean>
</form-beans>
<global-exceptions />
<global-forwards />
<action-mappings>
<action path="/login" name="UserForm" type="com.inspur.controll.UserAction" input="/login.jsp" validate="true">
<forward name="success" path="/success.jsp"></forward>
<forward name="fail" path="/error.jsp"></forward>
</action>
<action path="/regist" name="UserForm" type="com.inspur.controll.RegistAction" input="/regist.jsp" validate="true">
<forward name="registSuccess" path="/registSuccess.jsp"></forward>
<forward name="registFail" path="/registFail.jsp"></forward>
</action>

</action-mappings>

<controller processorClass="filter.CharFilter">
</controller>
<message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>

主要添加的元素师<controller>添加的属性是processorClass值为过滤器的类路径。
