浅谈SpringBoot主流读取配置文件三种方式

@Data
@Component
public class ApplicationProperty {
  @Value("${application.name}")
  private String name;
}

@Data
@ConfigurationProperties(prefix = "developer")
@Component
public class DeveloperProperty {
  private String name;
  private String website;
  private String qq;
  private String phoneNumber;
}

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-configuration-processor</artifactId>
      <optional>true</optional>
</dependency>

//使用方法
private final ApplicationProperty applicationProperty;
private final DeveloperProperty developerProperty;

@Autowired
  public PropertyController(ApplicationProperty applicationProperty, DeveloperProperty developerProperty) {
    this.applicationProperty = applicationProperty;
    this.developerProperty = developerProperty;
  }

@GetMapping("/property")
  public Dict index() {
    System.out.println("name:"+applicationProperty.getName());
    System.out.println("version:"+applicationProperty.getVersion());
    System.out.println("DevName:"+applicationProperty.getDeveloperName());
  }

static Props props1 = new Props("application.properties",CharsetUtil.CHARSET_UTF_8);

static Setting setting = new Setting("application-dev.yml", CharsetUtil.CHARSET_UTF_8,true);

public class Constant {
  
  static Props props1 = new Props("application.properties",CharsetUtil.CHARSET_UTF_8);

  static Setting setting = new Setting("application-dev.properties", CharsetUtil.CHARSET_UTF_8,true);

  public static final String Name ;
  public static final String SettingName ;

  static {
    Name = props.getStr("application.name");
    SettingName = setting.getByGroup("name","application");

  }
}

System.out.println(Constant.DevName+"------"+Constant.DevWebsite);
