JS 中对应的代码如下

 layui.config({
        //base: '../../../../static/plugins/layui/extend/'
        base: '[[@{/static/plugins/layui/extend/}]]'
    }).extend({
        treetable: 'treetable-lay/treetable'
    }).use(['layer', 'table', 'treetable'], function () {
        var $ = layui.jquery;
        var table = layui.table;
        var layer = layui.layer;
        var treetable = layui.treetable;
        // 渲染表格
        var renderTable = function () {
            layer.load(2);
            treetable.render({
                treeColIndex: 1,
                treeSpid: -1,
                treeIdName: 'id',
                treePidName: 'pid',
                treeDefaultClose: true,
                treeLinkage: false,
                elem: '#table1',
                url: '[[@{/static/data.json}]]',
                page: false,
                cols: [[
                    {type: 'numbers'},
                    {field: 'name', title: 'name'},
                    {field: 'id', title: 'id'},
                    {field: 'sex', title: 'sex'},
                    {field: 'pid', title: 'pid'}
                	]],
                done: function () {
                    layer.closeAll('loading');
                }
            });
        };
       renderTable();
    });
​

解决方式

1.也就是把 cols 后的[[ ]]变为

[

    [
		//TODO
    ]

]
​

因为[[…]]之间的表达式在 thymeleaf 被认为是内联表达式,所以渲染错误

2.或者在 <script type="text/javascript"> 加上 th:inline="none"

<script type="text/javascript"  th:inline="none">
​

但是这样的话，前面在 base 中使用 [[@{}]] 的标签也不能解析了，所以还是使用第一种方案，以后可以根据情况来解决。
