struts2的Action接收参数乱码问题

Question

Action接到值为乱码， 而Action执行页面显示正常，该如解决此问题？ 页面是UTF-8格式，工程数据库都是此格式
我下面Action的println为：=============================================С??
如正常打印语句为：=============================================小白
页面传值；
<td><s:url id="topageEditAction"
action="topageEditAction.action">
<s:param name="name" value="%{name}" />
</s:url> <s:a href="%{topageEditAction}">修改学生信息</s:a>
Action：
package action.student;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;import org.apache.struts2.ServletActionContext;import model.Student;import com.opensymphony.xwork2.ActionSupport;
import common.Base;
public class TopageEditAction extends ActionSupport {
public String name;
        ...... public String getName() {
return name;
} public void setName(String name) {
this.name = name;
}
        ......

@Override
public String execute() throws Exception {
System.out.println("============================================="+name);
// 创建空BASE
Base b = new Base();
// 通过username得到相应实例
Student student = b.getStudent().get(name); email = student.getEmail();
                ......
return "topageEdit";
}}

Answer 1

name1=name.getBytes("iso-8859-1"),"utf-8";System.out.println("============================================="+name1); 

Answer 2

用经典编码过滤器吧
org.springframework.web.filter.CharacterEncodingFilter

Answer 3

使用spring的前提下在web.xml中配置
<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>
