针对springboot 使用dwr出现ContainerConfigurationException IllegalArgumentException: name异常的解决方案

针对springboot 使用dwr出现ContainerConfigurationException IllegalArgumentException: name异常的解决方案

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：

	

id: 如果id为空 即赋值name,
name: 查询、传递后台参数
dicCode: 字典CODE
defaultValue: 默认选择值
must: true/false 是否必选
blank: 未选提示信息



 单选项字典列表查询
@if(isEmpty(user)) {
	
@}else {
	
@}

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
    dwr
    3.0.3-SNAPSHOT
    system
    ${project.basedir}/src/main/resources/libraries/dwr-3.0.3-SNAPSHOT.jar




​​​​​​​
    org.springframework.boot
    spring-boot-maven-plugin
    
        true
    

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！！
