Spring Boot 项目用外部Tomcat部署实践

一. 新建spring boot工程

1. 把项目打包方式改为war包

<groupId>com.example</groupId>
<artifactId>tomcat-demo</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>

2. 引入spring-boot-starter-tomcat

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- 设置为provided, 在打包时会将该包排除，因为要放到独立的tomcat中运行，不需要。 -->
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-tomcat</artifactId>
	<scope>provided</scope>
</dependency>

3.  修改启动类，继承 SpringBootServletInitializer 重写 configure 方法，并加入测试方法hello()。

@RestController
@SpringBootApplication
public class TomcatDemoApplication extends SpringBootServletInitializer{

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

	@GetMapping("/hello")
	public String hello() {
		return "hello world";
	}

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
		return builder.sources(TomcatDemoApplication.class);
	}
}

4. 打包（跳过测试）

package -DskipTests

二. 把项目部署到Tomat中

1. 把打好的war包放到Tomcat的webapp/ROOT目录下并解压

[root@rocketmq-nameserver1 ROOT]# pwd
/home/zhaoxing/apache-tomcat-8.5.32/webapps/ROOT
[root@rocketmq-nameserver1 ROOT]# ls
tomcat-demo-0.0.1-SNAPSHOT.war
[root@rocketmq-nameserver1 ROOT]# unzip tomcat-demo-0.0.1-SNAPSHOT.war 
Archive:  tomcat-demo-0.0.1-SNAPSHOT.war
   creating: META-INF/
   inflating: META-INF/MANIFEST.MF    
   creating: org/
   creating: org/springframework/
   creating: org/springframework/boot/
   creating: org/springframework/boot/loader/
   creating: org/springframework/boot/loader/data/
   ...  
[root@rocketmq-nameserver1 ROOT]# ls
META-INF  org  tomcat-demo-0.0.1-SNAPSHOT.war  WEB-INF

2. 在Tomcat bin目录下启动脚本start.sh

[root@rocketmq-nameserver1 ROOT]# cd /home/zhaoxing/apache-tomcat-8.5.32/bin/
[root@rocketmq-nameserver1 bin]# ls
bootstrap.jar       commons-daemon.jar            daemon.sh         setclasspath.sh  startup.sh            tool-wrapper.sh
catalina.bat        commons-daemon-native.tar.gz  digest.bat        shutdown.bat     tomcat-juli.jar       version.bat
catalina.sh         configtest.bat                digest.sh         shutdown.sh      tomcat-native.tar.gz  version.sh
catalina-tasks.xml  configtest.sh                 setclasspath.bat  startup.bat      tool-wrapper.bat
[root@rocketmq-nameserver1 bin]# ./startup.sh

[root@rocketmq-nameserver1 bin]# ps -ef |grep tomcat

3. 测试

[root@rocketmq-nameserver1 bin]# curl http://127.0.0.1:8080/hello
hello world[root@rocketmq-nameserver1 bin]# 

注：主机上访问关闭防火墙
