如何修复 java.lang.ClassNotFoundException: org.springframework.boot.configurationprocessor.json.JSONException 错误？

Question

当我在生产中将 Spring Boot 服务作为 Windows 服务运行时，出现以下错误。 服务 exe 由Jar2exe创建。

Answer 1

您的 mindBodyClientServiceImpl 正在（间接）使用的类是 org.springframework.boot.configurationprocessor.json.JSONException。

这来自您的 build.gradle：

annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'

由于您已在此处声明为 compileOnly：

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

但显然 JSONException 在运行时使用，它会使您的应用程序在使用 Jar2exe 打包时失败。 对此的解决方案可能是像这样包含整个依赖项：

implementation 'org.springframework.boot:spring-boot-configuration-processor'

只是一个盲目的猜测，但您的应用程序可能会再次失败，但这次至少您可以看到 JSONException 并修复潜在问题。
