Use tomcat to deploy SpringBoot war package in centos environment

Prepare war package

1. Prepare the existing SpringBoot project and add dependencies in pom

1) Set the packaging format to war

 <packaging>war</packaging>

2) Exclude the tomcat embedded in SpringBoot

 <!-- When deploying in war package, you need to exclude the embedded tomcat -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-tomcat</artifactId>
			<scope>provided</scope>
		</dependency>
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
			<version>3.1.0</version>
		</dependency>

3) Configure plugin

From the original

<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

Configure

<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<configuration>
					<fork>true</fork>
					<!-- Add jvm parameters -->
					<jvmArguments>Dfile.encoding=UTF-8</jvmArguments>
					<!-- Specify the entry class -->
					<mainClass>com.peko.filemanager.Application</mainClass>
				</configuration>
			</plugin>
		</plugins>
	</build>

2. Configure the startup class

From the original

@SpringBootApplication
public class Application {
 
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}

Configure

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
 
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
 
	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
		return builder.sources(Application.class);
	}
}

3. Packaging with Maven Tools

Clean first, then package

After success, you can find the packaged war package in the target folder

Copy it and then change the name. Here I changed it to helloworld.war

Deploy to tomcat on centos

1. First, install tomcat

2. Upload the war package to tomcat/webapps using the sftp tool

Restart tomcat

systemctl restart tomcat

Then open the tomcat management interface

You can see that the project is in the startup state. If it is in the shutdown state, go to the log under tomcat/logs to see what error is reported.

Note: If the war file is deployed in tomcat, the port number and other information originally configured in the yml file will be invalid.
