CVM: spring boot is a good thing, it can be launched directly in the main method without a container, and no configuration file is needed, so it is convenient to build the environment quickly. However, when we want to start two springboot projects at the same time, there will be a problem. It is possible that port 8080 is occupied by the first application and the second application cannot be started, so we need to modify the startup port of one of the projects.

This can be achieved by implementing the EmbeddedServletContainerCustomizer interface:

Public class Application extends SpringBootServletInitializer implements EmbeddedServletContainerCustomizer {

@ Override

Protected SpringApplicationBuilder configure (SpringApplicationBuilder builder) {

Return builder.sources (Application.class)

}

Public static void main (String [] args) {

SpringApplication.run (Application.class, args)

}

@ Override

Public void customize (ConfigurableEmbeddedServletContainer container) {

Container.setPort (8081)

}

}

PS: let's take a look at spring boot creation application port conflict 8080

If the 8080 port number on your computer is occupied by another program (such as jenkins), running lightsword will report the following error: java.net.BindException: Address already in use.Failed to start component [Connector [HTTP/1.1-8080]].

Solution: create a new file under the src- > main- > resources directory, named application.properties (this is the SpringBoot unified configuration file) and add the following line: (take a port number available on your computer, such as 9527 below, those who have seen Sing Yeh movies will know it) server.port = 9527

Just run it again.
