TemplateProcessingException Could not parse as expression
出现异常：
org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: “class path resource
Caused by: org.thymeleaf.exceptions.TemplateProcessingException: Could not parse as expression: "
{type: ‘checkbox’, fixed: ‘left’},
{field:‘xx’, fixed: ‘left’, width:80, title: ‘ID’, sort: true},
{field:‘xx’, title: ‘xxx’},
{field:‘xxx’, title: ‘xxx’},
{field:‘xxxx’, title: ‘xxx’},
{field:‘xxx’, title: ‘xxxx’},
" (template: “page/xxx” - line 43, col 26)
原因：
在page/xxx页面”
{type: ‘checkbox’, fixed: ‘left’},
{field:‘xx’, fixed: ‘left’, width:80, title: ‘ID’, sort: true},
{field:‘xx’, title: ‘xxx’},
{field:‘xxx’, title: ‘xxx’},
{field:‘xxxx’, title: ‘xxx’},
{field:‘xxx’, title: ‘xxxx’},
" 不能作为表达式，原因，在这字符串两边多了两对中括号，原来是layui的表格列的格式，但thymeleaf解析时将以上字符串当成表达式解析，所以出现此异常。
解决方案：
将[[
{type: ‘checkbox’, fixed: ‘left’},
{field:‘xx’, fixed: ‘left’, width:80, title: ‘ID’, sort: true},
{field:‘xx’, title: ‘xxx’},
{field:‘xxx’, title: ‘xxx’},
{field:‘xxxx’, title: ‘xxx’},
{field:‘xxx’, title: ‘xxxx’}
]]改为[
[
{type: ‘checkbox’, fixed: ‘left’},
{field:‘xx’, fixed: ‘left’, width:80, title: ‘ID’, sort: true},
{field:‘xx’, title: ‘xxx’},
{field:‘xxx’, title: ‘xxx’},
{field:‘xxxx’, title: ‘xxx’},
{field:‘xxx’, title: ‘xxxx’}
]
]，两对中括号中间加空格或者换行都行
