SpringBoot常用读取配置文件的3种方法小结

spring:
  test:
    name: yuanhaozhe
    age: 18
    phone: 1763173xxxx

@Configuration
@Data
public class ValueConfig {
    @Value("${spring.test.name}")
    private String name;

    @Value("${spring.test.age}")
    private int age;

    @Value("${spring.test.phone}")
    private String phone;

}

@Controller
public class BasicController {

	@Autowired
    private ValueConfig valueConfig;

    @RequestMapping("/test_valueConfig")
    @ResponseBody
    public String valueConfig(){
        return "name:".concat(valueConfig.getName()).concat(";age:").concat(String.valueOf(valueConfig.getAge()))
                .concat(";phone:").concat(valueConfig.getPhone());
    }


}
