4 SpringBoot 2.x系列--打包爲war

介紹在SpringBoot中打包爲war的方法。

文件目錄爲：

com
 +- data
     +- application
     	 +- controller
     	   +- Hello.java
         +- HelloWorld.java

HelloWorld.java：

@SpringBootApplication
public class HelloWoLrld extends SpringBootServletInitializer {

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

    public static void main(String[] args) {
        // Spring應用啓動
        SpringApplication s = new SpringApplication();
        s.setLogStartupInfo(false);
        // 懶初始化
        s.setLazyInitialization(true);
        s.run(HelloWorld.class, args);
    }

}

Hello.java:

@RestController
public class Hello {

    @RequestMapping("/hello")
    String home() {
        return "hello world";
    }
}

pom.xml:

        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>

            </plugin>
        </plugins>
    </build>
</project>

以上。
