我有一个包含三个模块的项目:A、B 和 COMMON。我想将通用逻辑放入 COMMON 模块(例如模型)中,然后放入依赖于它的其他两个模块。
两个模块(A、B)将分别构建以创建两个不同的 jar。
我正在测试它,尝试将日志依赖项放入 COMMON 模块中,然后构建 A 项目。它将正确构建,但如果我尝试使用“java -jar a.jar”运行 jar,则会失败并显示 NoClassDefFound:

但是我遇到了一个名为spring-boot-maven-plugin 的插件,其文档说明它的用途是打包可执行的 jar 或 war 档案并就地运行应用程序。
我的疑问是为什么我们需要这个?
如果我的打包可以告诉我要创建什么然后可以部署它运行,那么这个插件有什么用。
我正在尝试理解一个新项目,所以想确保每一行都有意义
我之前可以在 Spring Boot Version 2 中使用 Prometheus,没有任何问题。将 Spring Boot 版本更新到 2.1.1 后。发布我遇到以下错误。
我将 Prometheus 版本从 0.2.0 升级到 0.6.0 但仍然遇到相同的错误。
您认为 prometheus 与 Spring Boot Version 2 不兼容吗?
