org.thymeleaf.exceptions.TemplateProcessingException: Could not parse as expression: "{.....}"异常的解决

页面由JSP改造成thymeleaf,系统没有报页面有错误，于是启动，访问对应页面时，报出一长串异常，核心是org.thymeleaf.exceptions.TemplateProcessingException: Could not parse as expression: "{.......}"，刚开始遇到这个异常，也是一时手足无措，前后台各种找BUG，还是老样子，最后上网搜索，才知道，一些有JSP页面的写法，在thymeleaf是行不通的，按JSP的写法，thymeleaf渲染错误，下面是我原来的写法：

		columns:[[{
				field: "examTime",
				title: "检测时间",
				width: 140,
				align: "center",
				formatter: function(val){
					if(val){
 						return val.substring(0,19);
					}
					return val;
 				}
			}, {
				field: "tempC",
				title: "体温",
				width: 140,
				align: "center"
 			}, {
 			    
				field: "descript",
				title: "风险描述",
				width: 250,
				align: "center",
				 formatter: function(val, row, idx){
					if(val && row.level>0){
						return "<label title=\"" + val + "\" style=\"color: #FF0000;\">" + 
                    val + "</label>";
					}
					return "";
				} 
			
          }]]
			

因为[[…]]之间的表达式在thymeleaf被认为是内联表达式,所以无法正常渲染，页面也就访问不了了，正确的写法是把columns后面的[分行写，不要写在一行里，如下：

	columns:[
			 [
			  {
				field: "examTime",
				title: "检测时间",
				width: 140,
				align: "center",
				formatter: function(val){
					if(val){
 						return val.substring(0,19);
					}
					return val;
 				}
			}, {
				field: "tempC",
				title: "体温",
				width: 140,
				align: "center"
 			}, {
 			    
				field: "descript",
				title: "风险描述",
				width: 250,
				align: "center",
				 formatter: function(val, row, idx){
					if(val && row.level>0){
						return "<label title=\"" + val + "\" style=\"color: #FF0000;\">" 
                   + val + "</label>";
					}
					return "";
				} 
			}
		   ]
		 ]
