东方通部署WAR包

项目打包

1.启动类

@RestController
public class Application  extends SpringBootServletInitializer {
	@Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder	application){
        return application.sources(Application.class);
    }
}

2.pom.xml

<!--        打包方式为war包	-->
<packaging>war</packaging>

<!--        &禁止springboot 内嵌tomcat启动	-->
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
</dependency>

<finalName>ROOT</finalName>
<plugins>
		<plugin>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <!--如果想在没有web.xml文件的情况下构建WAR，请设置为false。-->
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
       	</plugin>
<plugins>

3.前端放resource/static目录下

部署应用

目前踩的坑

1.内存溢出

<!--	进入东方通部署目录	 -->
cd bin/
vi external.vmoptions
调整参数	 XX:MaxMetaspaceSize

2.遇到如下情况需调整参数
