Question

我有Maven Spring Boot项目，我配置为在Tomcat 8.5服务器上运行。我在Eclipse Java EE IDE中运行并开发它。

pom.xml是：

df.createOrReplaceTempView("position_table")

spark.sql("""
    select id, concat_ws(',', position.coordinates) as position_coordinates
    from position_table
  """).
  show(false)
//+-----+--------------------+
//|id   |position_coordinates|
//+-----+--------------------+
//|11700|48.597315,-43.206085|
//|11800|49.611254,-43.90223 |
//+-----+--------------------+

application.properties是（用*****替换敏感数据）：

Tomcat设置是：

静态Web内容位置是：

我无法做的是： 1.每次更改静态资源时停止重新部署整个项目（包括Java和DB部分）; 2.查看日志控制台我可以看到Spring Boot启动了两次，所以我希望它只启动一次。

Answer 1

试图关注此网站：https://www.logicbig.com/tutorials/spring-framework/spring-boot/restart-exclude.html

我以为我的问题找到了答案，但由于某种原因，我的系统会忽略application.properties spring.devtools.restart.exclude setup。

所以解决问题的方法就是我将我的Web App HTML / CSS / JS内容从\ src \ main \ resources \ static移到了\ src \ main \ webapp文件夹。

但是“Spring Boot开始两次”的问题仍然存在。任何帮助对我都有好处。

如何在每次更改静态资源时停止在Tomcat服务器上运行的Spring Boot项目重新部署它？
