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

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

view plaincopy to clipboardprint?

     
     encoding 
     org.springframework.web.filter.CharacterEncodingFilter 
      
      encoding 
      UTF-8 
    
 
   
 
     
     encoding 
     /* 
   
 



org.springframework.web.filter.CharacterEncodingFilter 中的转码部分:

view plaincopy to clipboardprint?

    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); 
    }
