? 常用的starter以及用处可以列举如下：

?
package yg.boot.action;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@EnableAutoConfiguration
@RequestMapping("/test")
public class AppController {
@RequestMapping("/sayhello")
public String sayHello(){
return "Hello World!";
}
}
?
Spring Boot启动 写道 @SpringBootApplication是这个注解是该应用程序入口的标志，然后有熟悉的main函数，通过SpringApplication.run(xxxApplication.class, args)来运行Spring Boot应用。打开SpringBootApplication注解可以发现，它是由其他几个类组合而成的：@Configuration（等同于spring中的xml配置文件，使用Java文件做配置可以检查类型安全）、@EnableAutoConfiguration（自动配置）、@ComponentScan（组件扫描，大家非常熟悉的，可以自动发现和装配一些Bean）?
# DataSource settings spring.datasource.url=jdbc:postgresql://localhost:5432/jcbk spring.datasource.username=jcbk spring.datasource.password=123456 spring.datasource.driver-class-name=org.postgresql.Driver # Tomcat Server settings (ServerProperties) server.port= 9080 server.address= 127.0.0.1 server.sessionTimeout= 30 server.contextPath= / # Tomcat specifics tomcat.accessLogEnabled= false tomcat.protocolHeader= x-forwarded-proto tomcat.remoteIpHeader= x-forwarded-for tomcat.basedir= tomcat.backgroundProcessorDelay=30 \# secs
?
package yg.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Hello world!
*/
@SpringBootApplication
public class App {
public static void main(String[] args ){
SpringApplication.run(App.class,args);
}
}
写道
直接运行App后，结果如下图所示。启动后访问http://localhost:9080/test/sayhello, 输出?Hello World!

项目打包 写道 项目打包使用maven-jar-plugin插件即可，生成boot-0.0.1-SNAPSHOT.jar。spring-boot-maven-plugin插件将boot-0.0.1-SNAPSHOT.jar重命名为boot-0.0.1-SNAPSHOT.jar.original,然后生成新boot-0.0.1-SNAPSHOT.jar包,目录结构为：?
