public class EncodeFilter implements Filter {
@Override
public void destroy() {
// TODO Auto-generated method stub
}
@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub
//从浏览器中的到的二进制数据用utf-8编码
request.setCharacterEncoding("UTF-8");
chain.doFilter(request, response);
}
在web.xml文件中配置filter：
<filter>
<filter-name>encoding</filter-name>
<filter-class>cn.itcase.strutsdemo.user.domain.EncodeFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<servlet-name>action</servlet-name>
</filter-mapping>
②. 提供自定义的 ActionServlet
public class MyActionServlet extends ActionServlet {
private static final long serialVersionUID = 5165092497954010055L;
@Override
protected void process(HttpServletRequest request,
HttpServletResponse response) throws IOException, ServletException {
request.setCharacterEncoding("UTF-8");
super.process(request, response);
}
}
web.xml 文件中
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
改为
<servlet-class>cn.itcast.struts.servlet.MyActionServlet</servlet-class>
③. 提供自定义的 RequestProcessor
public class MyRequestProcessor extends RequestProcessor {
@Override
public void process(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
request.setCharacterEncoding("UTF-8");
super.process(request, response);
}
}
在 struts-config.xml 文件中加入如下内容:
<controller processorClass="cn.itcast.struts.servlet.MyRequestProcessor"/>
@Override
public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
} |
