确保 spring.factories 文件正确配置并位于 src/main/resources/META-INF 目录下：

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  com.example.threadpoolstarter.ThreadPoolAutoConfiguration

打包和安装到本地仓库

mvn clean install

测试 MyTestAppApplication

在另一个 Spring Boot 应用中使用你的自定义 Starter，在pom.xml 中添加依赖项：

<dependency>
    <groupId>com.example</groupId>
    <artifactId>my-thread-pool-starter</artifactId>
    <version>1.0.0</version>
</dependency>

然后在该应用的 application.properties 或 application.yml 文件中配置你的线程池属性：

threadpool.enabled=true
threadpool.corePoolSize=10
threadpool.maxPoolSize=50
threadpool.queueCapacity=100
threadpool.threadNamePrefix=CustomThreadPool-
