我正在处理一个简单的场景,我正在启动一个spring Boot 应用程序,在此之前,我正在剥离mysql容器。我正在使用docker-compose,但我得到了no main manifest attribute
错误。以下是我的pom.xml

下面是docker-compose文件。
version: '3'
services:
app:
container_name: spring_boot_app
build: ./
ports:
- "8080:8080"
depends_on:
- mysql
environment:
SPRING_DATASOURCE_URL: jdbc:mysql://localhost:3306/user_management
mysql:
image: mysql:8.1.0
ports:
- "3307:3036"
environment:
MYSQL_ROOT_USER: root
MYSQL_ROOT_PASSWORD: password
我在谷歌上搜索并对pom.xml进行了调整,但仍然不起作用。
如果我单独启动spring Boot 应用程序,那么它工作正常,但只在docker-compose中出错。
有没有想过这里缺少了什么?

1.你是否在某个地方有一个注解为
@SpringBootApplication
的类给出了main方法?1.此外,我不知道这是否有区别,但我以这种方式调用插件,并向其添加
executable = true
配置:
