jsp/servlet乱码解决

1 解决方法 <% @ page contentType = " text/html;charset=utf-8 "  %>

2 response.setCharacterEncoding("utf-8");//响应编码类型response.setContentType("text/html;charset=utf-8");//设置文档类型request.setCharacterEncoding("utf-8");//请求编码类型

3 new String(request.getParameter("name").getBytes("ISO8859_1"),"utf-8");

4 修改tomcat的server.xml

<Connector port="8080" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" URIEncoding="utf-8"

/>

5过滤器配置web.xml

<filter>

<filter-name>w1</filter-name>Set Character Encoding

<filter-class>com.hw.controller.ErrorFilter</filter-class>SetCharacterEncodingFilter

</filter>

<filter-mapping>

<filter-name>w1</filter-name>Set Character Encoding

<url-pattern>/*</url-pattern>

</filter-mapping>
