struts2 action中获得属性为乱码问题解决方案

1、在struts.xml中添加：

<constant name="struts.i18n.encoding" value="utf-8" />

2、使用filter

package com.uu.filter;

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;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

* @author Administrator 下午11:10:28

*/

public class EncodingFilter implements Filter {

/*

* (non-Javadoc)

*

* @see javax.servlet.Filter#destroy()

*/

@Override

public void destroy() {

// TODO Auto-generated method stub

}

/*

* (non-Javadoc)

*

* @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest,

* javax.servlet.ServletResponse, javax.servlet.FilterChain)

*/

@Override

public void doFilter(ServletRequest arg0, ServletResponse arg1,

FilterChain arg2) throws IOException, ServletException {

HttpServletRequest request = (HttpServletRequest) arg0;

request.setCharacterEncoding("UTF-8");

HttpServletResponse response = (HttpServletResponse) arg1;

arg2.doFilter(request, response);

}

/*

* (non-Javadoc)

*

* @see javax.servlet.Filter#init(javax.servlet.FilterConfig)

*/

@Override

public void init(FilterConfig arg0) throws ServletException {

// TODO Auto-generated method stub

}

}

配置 web.xml:

<!-- encodingFilter -->

<filter>

<filter-name>Encoding</filter-name>

<filter-class>com.uu.filter.EncodingFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>Encoding</filter-name>

<url-pattern>*.do</url-pattern>

</filter-mapping>

搞定！！！
