How to prevent auto start of tomcat/jetty in Spring Boot when I only want to use RestTemplate
提问by datree
I want to use RestTemplate/TestRestTemplate by including the artifact in a SpringBoot application
我想通过在 SpringBoot 应用程序中包含工件来使用 RestTemplate/TestRestTemplate
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
</dependency>
But this automatically starts Tomcat or Jetty. Is there a way to turn it off, or by not including the above artifact. TestRestTemplate is in the boot artifact, but not the base RestTemplate.
但这会自动启动 Tomcat 或 Jetty。有没有办法关闭它，或者不包括上述工件。TestRestTemplate 在引导工件中，但不在基础 RestTemplate 中。

Spring Boot is not going to start a web container if it's not present. spring-webdoes not provide any embedded container. You may want to analyse the dependencies of your project (try mvn dependency:tree).
如果 Web 容器不存在，则 Spring Boot 不会启动它。spring-web不提供任何嵌入式容器。您可能想要分析项目的依赖项（尝试mvn dependency:tree）。
If you want to make sure a web server is not started in your spring boot application, you can set the following configuration key
如果你想确保你的 spring boot 应用程序中没有启动 web 服务器，你可以设置以下配置键
spring.main.web-application-type=none
Or you can use the SpringApplicationBuilder
或者你可以使用 SpringApplicationBuilder
new SpringApplicationBuilder(YourApp.class)
.web(WebApplicationType.NONE).run(args);

Since Spring Boot 2.0.0 this property is deprecated and following is the new way:
从 Spring Boot 2.0.0 开始，此属性已被弃用，以下是新方法：
spring.main.web-application-type=none
This change is because Spring Boot the support for reactive server.
这种变化是因为 Spring Boot 支持响应式服务器。

You can just close the app according to https://spring.io/guides/gs/async-method/. Although this still stars Tomcat, but will stop the app at the end without keeping the tread running.
您可以根据https://spring.io/guides/gs/async-method/关闭应用程序。虽然这仍然是 Tomcat 的明星，但会在最后停止应用程序而不保持步调运行。
SpringApplication.run(MyApp.class, args).close();
