springBoot打war包部署tomcat

1、修改maven的pom.xml文件

<packaging>war</packaging>

2、排除springboot内嵌的tomcat

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

3、添加tomcat依赖，该依赖不打包到war包中

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <!--scope改为provided 表示打包是省略 此项-->
            <scope>provided</scope>
        </dependency>

4、配置启动类

首先需要继承SpringBootServletInitializer抽象类

class EshibernApplication extends SpringBootServletInitializer

实现configure方法

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

完整代码如下

@SpringBootApplication
public class EshibernApplication extends SpringBootServletInitializer {

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

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

5、通过maven打包

mvn clean package -Dmaven.test.skip=true

6、将war包放入tomcat的webapps目录中

7、启动tomcat。
