Spring3新特性：graalvm打包Springboot+Mybatis

问题1

org.apache.catalina.LifecycleException: An invalid Lifecycle transition was attempted ([before_stop]) for component
用不了反射，所以需要这个文件去

在这里插入图片描述

问题2

无法读取外部 DTD ‘mybatis-3-mapper.dtd’, 因为 accessExternalDTD 属性设置的限制导致不允许 ‘http’ 访问。

允许对 ‘http’ 的访问：
如果你确定从 ‘http’ 地址下载 DTD 文件是安全的，可以配置解析器以允许对 ‘http’ 的访问。在 Java 中，可以使用以下代码：

System.setProperty("javax.xml.accessExternalDTD", "all");
