起初我使用layui做的后台项目，发现数据表格好像不支持数据字典的转换功能，网上搜了一大堆，终于找到dwr可以实现此功能：layui表格数据字典转换实现DWR_wuyue521_2008的专栏-CSDN博客
最后实现起来了，确实很好使，数据表格根据字典查询显示出来了，给大家分享一下我的数据字典在layui应用的笔记：
js 模板添加字典查询：
{field:'islink',title: '是否跳转', width:100, align:'center',
templet:function(d){ return getDictionaryValue('common_boolean',d.islink)}}
标签字典列表查询：
字典类型：
可当我兴冲冲的将项目打包成.jar，部署到公司线上服务器上时，却发现只要用到数据字典的列表通通不能用了，我当时懵了，明明在本地能使用，为啥部署到线上出问题了？
我查了一下控制台报错信息，如下：

翻阅了好多资料，最终确定是导入了dwr-3.0.2-RELEASE.jar有问题，类加载器没有在内嵌tomcat处理好。
于是我就翻翻他们在github开源的dwr issues，还真找到了，哈哈
原贴问题在这里：SpringBoot Issue - LaunchedURLClassLoader throws java.lang.IllegalArgumentException · Issue #2 · directwebremoting/dwr · GitHub
已经有人将这个问题解决并编译过了，下载dwr-3.0.3-SNAPSHOT即可
maven就添加本地的吧：
org.directwebremoting dwr3.0.3-SNAPSHOT system ${project.basedir}/src/main/resources/libraries/dwr-3.0.3-SNAPSHOT.jar org.springframework.boot spring-boot-maven-plugintrue
重新打包上传线上~启动~
如果哪位大佬有更好的方式解决方法，小弟受教！！
