springBoot部署jar、war

1. jar包部署

maven插件：
<build>
   <plugins>
     <plugin>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>
   </plugins>
</build>

如果没有加插件，就执行jar包

java -jar xxx.jar
错误信息：no main manifest attribute, in xxx.jar

如果有安装maven就直接用maven打包就行

jar包的目录结构

example.jar
                     |
                     +-META-INF
                     |  +-MANIFEST.MF
                     +-org
                     |  +-springframework
                     |     +-boot
                     |        +-loader
                     |           +-<spring boot loader classes>
                     +-BOOT-INF
                        +-classes
                        |  +-mycompany
                        |     +-project
                        |        +-YourClasses.class
                        +-lib
                           +-dependency1.jar
                           +-dependency2.jar

2. war包启动

1)在pom.xml中将打包形式 jar 修改为war <packaging>war</packaging>

2)构建项目名称在<bulid>里面 <finalName>xdclass_springboot</finalName>

3)放置到tomcat里面的webapp里面

4)修改启动类

// 进行初始化
public class WebApplication extends SpringBootServletInitializer {

                @Override
                protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
                    return application.sources(WebApplication.class);
                }

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

            }
