springboot微服务打WAR包部署

1、修改项目的POM文件
修改项目的打包形式为 WAR包

去除掉springboot项目自带的tomcat包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>1.5.10.RELEASE</version>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>

添加 servlet-api包

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>

修改springboot项目与JSP页面编译的包
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<version>8.5.27</version>
<scope>provided</scope>
</dependency>
添加springboot项目打WAR包插件
<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.2.0</version>
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>

2、修改springboot项目启动类，继承 SpringBootServletInitializer 类，重写configure方法
@SpringBootApplication
public class ApplicationTest extends SpringBootServletInitializer
{

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder)
    {
        return builder.sources(this.getClass());
    }
}

3、使用MAVEN打成 WAR包，最后将WAR包放到 tomcat的 webapp目录下，启动tomcat即可

4、用浏览器访问 http://localhost:tomcat端口号/WAR包名字/服务URL地址，例如：
http://localhost:8080/springboot-demo/user/hello
