js、URL传递含有中文参数时的乱码问题解决

1、使用代码完成字符集修改

方法（一）：
html页面：

function testOne() {

   var url =  "testOne_test.do?expr="+你好;

   location  = encodeURI(url);

}

 

后台java代码：

String expr = new String(request.getParameter("expr").getBytes("ISO-8859-1"),"UTF-8"); 

方法（二）：

html页面：

function testOne() {
   var url =  "testOne_test.do?expr="+你好;
   location = encodeURI(encodeURI(url));
}

 

后台java代码：
String expr = java.net.URLDecoder.decode(lrequest.getParameter("expr") , "UTF-8");

2、修改tomcat中的配置参数

在tomcat下面找到server.xml
<Connector port="8080" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" URIEncoding="GBK">
根据需要修改为UTF-8等字符集。

3、在web工程中添加spring.jar，使用spring的CharacterEncodingFilter

<filter> <filter-name>encoding</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>encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> 
 
org.springframework.web.filter.CharacterEncodingFilter 中的转码部分：

protected void doFilterInternal( HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException { if (this.encoding != null && (this.forceEncoding || request.getCharacterEncoding() == null)) { request.setCharacterEncoding(this.encoding); if (this.forceEncoding && responseSetCharacterEncodingAvailable) { response.setCharacterEncoding(this.encoding); } } filterChain.doFilter(request, response); }
