当我在生产环境中以Windows服务的形式运行Sping Boot 服务时，出现以下错误。服务exe由Jar2exe创建。

奇怪的是，当我在生产机器上通过Intellij Idea运行它时，它能正常运行。Intellij Idea中的服务exe和代码在我的开发机器上都能正常工作。以下是我的build.gradle文件：

您的mindBodyClientServiceImpl正在使用（间接）的类是org.springframework.boot.configurationprocessor.json.JSONException。
这是你的体型造成的

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是在运行时使用的，所以在打包Jar2exe时会导致应用失败。解决方案可能是包含整个依赖项，如下所示：

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

这只是一个盲目的猜测，但您的应用程序可能会再次失败，但这一次至少您可以看到JSONException并修复底层问题。

从SpringBoot 2.4开始，依赖项

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

不再包含在生成的fat-jar中（Sping Boot 2.4发行说明）。
Jar优化
当生成可运行的Sping Boot jar时，空的启动器依赖项现在将被自动删除。由于大多数启动器只提供可传递的依赖项，因此将它们打包到最终的jar中没有什么意义。
Sping Boot 注解处理器也被删除了，因为它们只在构建过程中有用。它们是spring-boot-autoconfigure-processor和spring-boot-configuration-processor。
如果异常是在您自己的代码中引发的，请检查您没有使用

org.springframework.boot.configurationprocessor.json.JSONException
org.springframework.boot.configurationprocessor.json.JSONObject

如果您正在使用它们，请更换它们，例如：

org.json.JSONException
org.json.JSONObject

您可能需要包含相关的dependency：

<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20220924</version>
</dependency>
