springboot怎么打包成war包并发布

一、场景：分布式测试、开发内存消耗比较大采用统一发布，Tomcat核心配置参考

            </Host>
        </Engine>
    </Service>




</Server>

二、springboot打包成war包

1、在pom配置文件中指定打包为war类型，并移除web中自带的tomcat

<packaging>war</packaging>


<exclusions>
    <exclusion>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
    </exclusion>
</exclusions>

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <scope>provided</scope>
</dependency>

2、修改build配置

 <build>
        <!-- 打包后的服务名称 -->
        <finalName>base-service-1.0.1</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!--可以不用添加web.xml-->
            <plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.0.0</version>
            </plugin>
            <plugin>
                <!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-deploy-plugin -->
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-deploy-plugin</artifactId>
                <!--deploy 时忽略 model-->
                <configuration>
                    <skip>true</skip>
                </configuration>
            </plugin>
        </plugins>
    </build>

3、修改启动类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(this.getClass());
    }

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


}

4、新增Tomcat注册到nacos配置

import com.alibaba.cloud.nacos.registry.NacosAutoServiceRegistration;
import com.alibaba.cloud.nacos.registry.NacosRegistration;
import org.springframework.boot.context.event.ApplicationReadyEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.EventListener;
import org.springframework.stereotype.Component;
import org.springframework.util.StringUtils;

import javax.annotation.Resource;

@Component
public class NacosListener implements ApplicationListener<ApplicationReadyEvent> {
    @Resource
    private NacosRegistration registration;

    @Resource
    private NacosAutoServiceRegistration nacosAutoServiceRegistration;

    @Override
    public void onApplicationEvent(ApplicationReadyEvent event) {
        String property = event.getApplicationContext().getEnvironment().getProperty("server.port");
        if (!StringUtils.isEmpty(property)) {
            registration.setPort(Integer.parseInt(property));
        }

        nacosAutoServiceRegistration.start();
    }

    @EventListener(ApplicationReadyEvent.class)
    public void onWebServerReady(ApplicationReadyEvent event) {
        String property = event.getApplicationContext().getEnvironment().getProperty("server.port");
        if (!StringUtils.isEmpty(property)) {
            registration.setPort(Integer.parseInt(property));
        }
        nacosAutoServiceRegistration.start();
    }
}

三、打包部署

1、清理项目并打包
