问题

启动SpringBoot项目后，直接退出，无报错信息。

2021-09-05 17:27:43.656  INFO 7336 --- [           main] cn.hsp.blog.BlogApplication              : Starting BlogApplication using Java 16.0.1 on jerrydeMacBook-Pro.local with PID 7336 (/Users/jerry/Downloads/blog/target/classes started by jerry in /Users/jerry/Downloads/blog)

进程已结束，退出代码为 0

解决方案

在pom.xml中添加依赖

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-web</artifactId>
</dependency>

完整pom.xml文件样例：

<?xml version="1.0" encoding="UTF-8"?>
