创建了两个JHipster项目，即帐户服务和api-gateway . 还从https://github.com/jhipster/jhipster-registry下载了JHipster Registry项目 . 并在Eclipse中导入了每个maven / gradle项目 .
我是Spring Cloud Config的新手，所以想要从JHipster测试当前生成的源代码，而无需修改任何源代码 . 但由于错误而无法执行微服务项目 .
首先我启动了Jhipster Registry，它在8761启动并运行 . 接下来我启动了api-gateway，它也在8765端口，并且能够看到在Jhipster Registry UI中注册的实例中列出的相同内容 .
之后我尝试在端口8081启动帐户服务，但由于错误无法进一步测试 .
不确定，如果我需要对这些生成的源进行任何更改，让它们开始工作，比如某些配置或yml更改......
发生以下错误，当我尝试启动微服务时： -
