具体错误原因是org.springframework.boot.configurationprocessor.json.JSONException这个类找不到了。经过一个多小时的排查发现此博客。
https://github.com/spring-projects/spring-boot/issues/24244
https://github.com/spring-projects/spring-boot/issues/22036
原因是项目pom使用了这个依赖，并且代码中使用了此依赖的类
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
import org.springframework.boot.configurationprocessor.json.JSONException;
import org.springframework.boot.configurationprocessor.json.JSONObject;
注意它是带有<optional>true</optional>可选标记的，编译打包时不会打包进去，导致打包后启动报错
解决方案
修改代码中的引用，JSON使用fastJason而不是spring-boot-configuration-processor中的JSON
