Spring boot spring boot发生非法的反射访问操作

您好，我无法运行我的

spring boot+H2 DB

应用程序，因此发生了一个非法的反射访问操作。我的Java版本是

jdk

10

并添加了依赖项

问题标题中的警告与您遇到的异常无关

该警告涉及Tomcat Catalina内部所做的一些事情，而这不是应该做的。但是，他们不打算解决这个问题，请参见

---

但是，例外情况是，您正在插入另一个id为1的Employee对象，而您已经有了一个。这似乎来自文件系统中的脚本，位于

C:/Users/subhashis/git/MicroservicesCloudBoot/currency exchange service/target/classes/data.sql

。您的脚本可能准备了一些数据，但第二次运行时失败了，因为您已经有了这些数据。

您的错误是将主键冲突视为语句（插入到employee（id，name）值（1，'a'））显示您的表中已经有id 1，并且希望再次将1添加到导致此问题的id字段中。与非法访问警告相关，您可以检查并报告org.apache.catalina.loader.WebappClassLoaderBase的维护人员以修复此问题。但是是的，这不是目前应用程序失败的原因。
