struts1.x数据从前台jsp到后台actionform中文乱码

struct1.x

数据从前台jsp到后台ActionForm中文乱码,把所有出现字符编码的都换成了UTF-8编码，最后还在Action操作加上request.setCharacterEncoding("UTF-8")；输出ActionForm获得的表单仍然是乱码。




struct2，听说request.setCharacterEncoding("UTF-8")；可以，我没有试过。

最后只能加上过滤器了，所幸

终于



成功

了啦！

代码如下：

EncodingFilter.java

package com.xxx.xxx;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class EncodingFilter implements Filter {

@Override
public void destroy() {
// TODO Auto-generated method stub

}

@Override
public void doFilter(ServletRequest arg0, ServletResponse arg1,
FilterChain arg2) throws IOException, ServletException {
// TODO Auto-generated method stub
arg0.setCharacterEncoding("UTF-8");
arg2.doFilter(arg0, arg1);
}

@Override
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub

}

}

web.xml:
<filter>
<filter-name>encoding</filter-name>
<filter-class>com.xxx.xxx.EncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
