Spring @RequestParam乱码问题

在网上找了很多资料才找到解决的方法,通过URL传递命名参数,后台接收的却是乱码解决方法如下:

方法一:将接收的参数重新编码

@RequestMapping(value="/handle")
public String handle81(@RequestParam("userName") String userName){        	
    userName=new String(userName.getBytes("ISO-8859-1"), "UTF-8")
    modelMap.put("userName", userName);
    return "/user/showUser";
}

方法二:在web.xml里面配置

        <!-- 字符过滤器 -->  
	<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>
	</filter>

	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping> 

方法三:修改tomcat的server.xml(在conf文件下),找到下面代码添加URIEncoding编码。 

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8"/>

 最终我的解决方法时方法二和方法三同时用,没用方法一才解决@RequestParam乱码问题。 

 

另外表单提交时出现乱码解决方法如下:

一、首先将Eclipse文件编码是UTF-8:Windows——Preference——General——Workspace——Text file encoding改为UTF-8.

二、设置页面编码

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"
    contentType="text/html; charset=utf-8"%>

<%
    request.setCharacterEncoding("utf-8");
%>

三、将form表单提交方式变为post方式,即添加method="post"

四、在action类中,添加3句话

        request.setCharacterEncoding("UTF-8");
        response.setContentType("text/html;charset=utf-8");
        response.setCharacterEncoding("UTF-8");

五、将接收到的数据转码

String  name = new String(request.getParameter(“name”).getBytes("ISO-8859-1"),"utf-8");

 六、post提交方式下可进行URL编码:

String info=java.net.URLEncoder.encode("你好吗.jpg","utf-8");

http://localhost:8080/webTest/index.jsp?name=<%=URLEncoder.encode("张三","UTF-8")%>

String myname=URLDecoder.decode(name,"UTF-8");
