Application.java

package org.spring.springboot;

import org.spring.springboot.property.HomeProperties;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;

/**

*

* Created by bysocket on 16/4/26.
*/
// Spring Boot 应用的标识
@SpringBootApplication
public class Application implements CommandLineRunner {

    @Autowired
    private HomeProperties homeProperties;

    public static void main(String[] args) {
        SpringApplication application = new SpringApplication(Application.class);
        //关闭banner
        application.setBannerMode(Banner.Mode.OFF);
        application.addListeners(new TestListener());
        application.run(args);
    }

   
    @Override
    public void run(String... args) throws Exception {
        System.out.println("\n" + homeProperties.toString());
        //System.out.println(configationSettings.getA());

        //FIXME run的时候加载xml的配置
        //SpringApplication.run("classpath:/META-INF/application-context.xml", args);

        //FIXME 加载启动数据 在implement CommandLineRunner 增加@Order()注解 指定加载顺序
        //code<加载数据>

        System.out.println();
    }
   
}
===================================
1.执行Application main方法 会按照applicaition.properties主配置文件 中激活dev来读取application-dev.properties输出homeProperties.toString()

2.打包方式 mvn clean package

java -Xms512m -Xmx1024m -jar springboot-properties-0.0.1-SNAPSHOT.jar --spring.profiles.active=prod --name="Spring" --server.port=9090 -Dlogging.path=/tmp

按照prod输出
