配置优先级
  1.命令行参数。
  2.通过 System.getProperties() 获取的 Java 系统参数。
  3.操作系统环境变量(env)。
  4.从 java:comp/env 得到的 JNDI 属性。
  5.通过 RandomValuePropertySource 生成的“random.*”属性。
  6.应用jar文件之外的属性文件。(通过-Dspring.config.location参数)
  7.应用jar文件内部的属性文件。
  8.在应用配置java类(包含“@Configuration”注解的java类)中通过“@PropertySource”注解声明的属性文件。
  9.在xml中通过context:property-placeholder或者PropertyPlaceholderConfigurer指定的属性文件。
  10.通过“SpringApplication.setDefaultProperties”声明的默认属性。
  

命令行参数
    SpringApplication 类默认会把以“--”开头的命令行参数转化成应用中可以使用的配置参数


RandomValuePropertySource 
    可以用来生成测试所需要的各种不同类型的随机值,从而免去了在代码中生成的麻烦。
    可以生成数字和字符串。数字的类型包含 int 和 long,可以限定数字的大小范围
    以“random.”作为前缀的配置属性名称由 RandomValuePropertySource 来生成


属性文件
    Spring Boot 提供的 SpringApplication 类会搜索并加载 application.properties 文件来获取配置属性值
        当前目录的“/config”子目录。
        当前目录。
        classpath 中的“/config”包。
        classpath
    可以通过“spring.config.name”配置属性来指定不同的属性文件名称。
    也可以通过“spring.config.location”来添加额外的属性文件的搜索路径。
    如果应用中包含多个 profile,可以为每个 profile 定义各自的属性文件,按照“application-{profile}”来命名
    对于配置属性,可以在代码中通过“@Value”来使用

1.To set a default value in Spring expression, use Elvis operator:
    #{expression ?: default value}	
如
    @Value("#{systemProperties['mongodb.port'] ?: 27017}")
	private String mongodbPort;

	@Value("#{config['mongodb.url'] ?: '127.0.0.1'}")
	private String mongodbUrl;	
	
	@Value("#{aBean.age ?: 21}")
	private int age;


2.To set a default value for property placeholder:
    ${property : default value}
如
  @Value("#{systemProperties['mongodb.port'] ?: 27017}")
  private String mongodbPort;

  //@Value("${mongodb.url:127.0.0.1}")
  @Value("#{config['mongodb.url'] ?: '127.0.0.1'}")
  private String mongodbUrl;

  @Value("#{aBean.age ?: 21}")
  private int age;
其中
config.properties
  mongodb.url=1.2.3.4
  mongodb.db=hello

“config” bean
//@PropertySource("classpath:/config.properties}")
//@Configuration
or “config” bean
//<util:properties id="config" location="classpath:config.properties"/>
+
//@Bean
//public static PropertySourcesPlaceholderConfigurer propertyConfigIn() {
//   return new PropertySourcesPlaceholderConfigurer();
//}


CommandLineRunner
  Spring Boot提供了一个CommandLineRunner接口,实现这个接口的类总是会被优先启动,并优先执行CommandLineRunner接口中提供的run()方法
  如果有多个CommandLineRunner接口实现类,那么可以通过注解@Order来规定所有实现类的运行顺序
