java后端接收汉字参数乱码问题处理(get请求)

方案一：java中将字符串转码

前端js

window.location.href=context +"/service/expertRecommend/addExpertAssess?note=测试汉字乱码";

后端

 @RequestMapping("/addExpertAssess")
    public String addExpertAssess(@RequestParam Map<String, Object> parameters) throws UnsupportedEncodingException {
    	
    	//解决汉字乱码问题
    	String note=new String(((String) parameters.get("note")).trim().getBytes("ISO-8859-1"), "UTF-8");
    	parameters.put("note", note);

方案二：前端编码+后端解码

通过encodeURI(encodeURI(checkText))提交，java代码中用URLDecoder.decode解码：

前端

<script>
function download(documentPath){
  var url = "<c:url value='/product/download.action?documentPath='/>"+documentPath;
  url = encodeURI(encodeURI(url));
  window.location.href=url;
}

后端

java代码中取中文：
String documentPath = (String) request.getParameter('documentPath');
documentPath = URLDecoder.decode(documentPath,"utf-8");

方案三：改为form表单提交

方案四：修改Tomcat编码

修改tomcat的server.xml中的connector，添加URLEncoding="UTF-8"
