java.lang.NoSuchMethodError : org. springframework.util.ReflectionUtils.accessibleConstructor

Question

我将此[可扩展性场景 352] ( https://extensibilityexplorer.cfapps.eu10.hana.ondemand.com/ExtensibilityExplorer/#/ExtScenario/352 )、[第二个应用程序] ( https://help.sap.com/viewer/4316f97a90ff48948fb7f212ecabf964/SHIP/en-US/413ac667f3dc4cab844d21d088171854.html ) 作为 Backbone 。然后，我更改了 POM 文件以迁移到 SDK v03。 通过这样做，我成功地构建了我的项目，但我在 Neo 部署方面遇到了问题。

备注:我不得不使用原样 POM，但我没有找到构建自定义 VDM 的方法。

我的 POM 文件:

你能告诉我我忘记了哪个依赖项吗？

彼得罗

Answer 1

org.springframework.util.ReflectionUtils.accessibleConstructor方法仅在最近可用 spring-core依赖版本。因为在你的 pom 文件中， spring-core依赖版本解析为 4.3.9.RELEASE ，这会导致问题。

快速解决方法是更新您的父项 spring-boot-starter-parent至版本2.2.4.RELEASE而不是1.5.4.RELEASE 。 这会自动更新 spring-core依赖版本也是如此。

希望这有帮助。
