SpringApplication application = new SpringApplication(Application.class);
Map<String,Object>defaultMap = new HashMap<String,Object>();
defaultMap.put("name","Isea-Blog");
//还可以是Properties对象
application.setDefaultProperties(defaultMap);
application.run(args);
2.2 应用（使用）属性
2.2.1 @Value(“${xxx}”)
这种方式是最简单的，通过@Value注解可以将属性值注入进来。
2.2.2 @ConfigurationProperties
Spring Boot 可以方便的将属性注入到一个配置对象中。例如：
my.name=Isea533
my.port=8080
my.servers[0]=dev.bar.com
my.servers[1]=foo.bar.com
对应对象：
@ConfigurationProperties(prefix="my")
publicclassConfig {
private String name;
private Integer port;
private List<String> servers = newArrayList<String>();
public String geName(){
returnthis.name;
 }
public Integer gePort(){
returnthis.port;
 }
public List<String>getServers() {
returnthis.servers;
 }
}

name=isea533
jdbc.username=root
jdbc.password=root
...

@ConfigurationProperties
publicclassConfig {
private String name;
privateJdbcjdbc;
 class Jdbc {
private String username;
private String password;
//getter...
 }
public Integer gePort(){
returnthis.port;
 }
publicJdbcgetJdbc() {
returnthis.jdbc;
 }
}

@ConfigurationProperties(prefix = "foo")
@Bean
publicFooComponentfooComponent() {
 ...
}

app.name=MyApp
app.description=${app.name} is a Spring Boot application

server.port=${port:8080}

@Component
@ConfigurationProperties(prefix="person")
publicclassConnectionSettings {
private String firstName;
}

@Component
@ConfigurationProperties(prefix="connection")
publicclassConnectionSettings {
@NotNull
privateInetAddressremoteAddress;
// ... getters and setters
}
