我有一个用JDK8开发的SpringBoot应用程序，现在已移植到JDK11。启动时出现以下异常：
ERROR SpringApplication: Application run failed

我尝试了从2.1.8到2.2.1的SpringWebStarter，但我总是遇到相同的错误。
我无法再次使用JDK8，因为该计算机已从Windows 7更新到Windows 10，而且我不愿意在Oracle注册以下载JDK8;）
有人遇到了这个问题吗？有人知道如何解决吗？

您的错误与Java模块系统有关：
java.lang.reflect.InaccessibleObjectException：无法访问jdk.internal.loader.ClassLoaders $ AppClassLoader（jdk.internal.loader.ClassLoaders $ PlatformClassLoader，jdk.internal.loader.URLClassPath）：模块java.base无法使用“打开jdk.internal.loader”到未命名的模块@ 2e3967ea
从堆栈跟踪来看，这是由Groovy引起的，因此您使用的是不支持JDK 9的Groovy旧版本，或者正在运行导入jdk.internal.loader的代码而未声明对Java模块的正确访问。
首先要检查您是否具有最近的Groovy依赖关系，但是一种快速的解决方法是使用以下命令运行JVM：
--add-opens java.base/jdk.internal.loader=ALL-UNNAMED

groovy 自动配置中出现异常，因此您可以在配置中禁用它：
@SpringBootApplication(exclude = {
GroovyTemplateAutoConfiguration.class})
或在属性文件中：
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.groovy.template.GroovyTemplateAutoConfiguration
在我的情况下，下一个属性也解决了这个问题：
spring.groovy.template.enabled=false
spring.groovy.template.check-template-location=false
