Js与java内置json与字符串转换函数

JS

js对象转json字符串

params = {}
params.attachmentIds = uploadAttachmentIds.join(",");

writeCookie("Imges", JSON.stringify(params), 1);

json字符串转js对象

var imgs = JSON.parse(readCookie("Imges"));

Java 传递json字符串并解析

前台

​
			var dataArr = new Array();
			var Row = _self.getSelectRows();
			for(var i=0;i<Row.length;i++)
			{
				var iceData = new Object(); 
				iceData.adviceFlowId = Row[i].iceFlowId;
				iceData.companyId = Row[i].comId;
				dataArr.push(iceData);
			}
			var checkUrl = CONTEXT_PATH +"/ice/beforeDel"
			var param ={
					"JsonArray":$.toJSON(dataArr)
			}
			var retData  = $.getData(checkUrl,param);

​

后台接收json字符串

	import com.alibaba.fastjson.JSON;
        @RequestMapping("/ice/beforeDel")
	@ResponseBody
	public AssembleJSON beforedeleteAdvice(String JsonArray,HttpServletRequest request)
	{	 
		String localOrgId = user.getOrgId();
		HashMap<String,Object> hashMap = new HashMap<String,Object>();
		List<String> ids = new ArrayList<>();
		String companyId = "";
		List<ice> iceList = JSON.parseArray(JsonArray, ice.class);
		for(ice ice:iceList) {
			String iceFlowId =ice.getIceFlowId();
			 comId = ice.getComId();
			AdviceFLowNodeVO upFLowNodeVO = new AdviceFLowNodeVO();
			upFLowNodeVO.setAdviceFlowId(iceFlowId);
			upFLowNodeVO.setCompanyId(comId);
			AdviceFLowNodeVO adviceFLowNodeVO = new AdviceFLowNodeVO();
			adviceFLowNodeVO = adviceFlowNodeService.getUpAdvice(upFLowNodeVO);	
}

Java的Json字符串转string

	public static String transJsonToString(String json)
	{
		String s = json.replaceAll("\\{\"","{'") // {"  --> {'
	            .replaceAll("\":\"", "':'")     // ":" --> ':'
	            .replaceAll("\",\"", "','")     // "," --> ','
	            .replaceAll("\":", "':")        // ":  --> ':
	            .replaceAll(",\"", ",'")        // ,"  --> ,'
	            .replaceAll("\"\\}", "'}")      // "}  --> '}
	            .replaceAll("\"", "")           // "   --> 空，以去掉字符串中间的引号
	            .replaceAll("'", "\"")          // '   --> "，所有的单引号替换回双引号
	            .replaceAll("<br />", "")       // 去掉字符串中的<br />
	            .replaceAll("\\\\", "?");       // 字符串中含\也会导致解析失败
		
		return s;
		
	}
