*  添加组件
    
        
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-configuration-processor</artifactId>
                    <optional>true</optional>
                </dependency>
    
     
 *  添加注解

import lombok.Data;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    
    @ConfigurationProperties(prefix = "app")
    @Data
    public class CustomProperties {
    
        private String appid;
        private String appkey;
        private String secretkey;
    }

import com.ciih.authcenter.util.CustomProperties;
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.context.properties.EnableConfigurationProperties;
    
    @SpringBootApplication
    @MapperScan(basePackages = "XXX.dao")
    @EnableConfigurationProperties(CustomProperties.class)
    public class AuthcenterApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(AuthcenterApplication.class, args);
        }
    
    }

*  配置文件已经有提示了
 *  ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlbnhpbmdjaGVu_size_16_color_FFFFFF_t_70][]
 *  使用配置:
    
        @RestController
        @RequestMapping("user")
        public class UserController {
        
            @Resource
            private CustomProperties customProperties;
        
            @PostMapping("information")
            public String information() {
                 return  customProperties.getAppid();
            }
        }
    
    大功告成了
