Spring 启动失败 Java 14

Question

我试图在 spring 引导中构建示例 java 14 程序，它构建成功但部署失败。我正在使用 H2 数据库来存储详细信息，实体 bean 不是从不同的 java 模块加载的。

请在此处查找代码库https://github.com/rjvharidas/spring-boot-java14-module

错误：

Answer 1

Not a managed type 当实体 class 不在 @EntityScan

下的包中时抛出异常

正如我在您的代码中看到的那样，您已经导入了 ServiceConfiguration，它具有

@EntityScan("com.rjv.bootcamp.javamodules.domain.*")

问题是指定的包格式错误，以 .* 结尾。可能，您应该将其替换为

@EntityScan("com.rjv.bootcamp.javamodules.domain")
