SpringBoot自定义配置步骤

1. 在yml中填写自定义配置

ly:
  sms:
    accessKeyId: # 短信配置
    accessKeySecret:
    signName: xx商城 # 签名名称
    verifyCodeTemplate: SMS_156565156 # 模板名称

2. 写对应配置类

@Data
@ConfigurationProperties(prefix = "ly.sms")
public class SmsProperties {
    private String accessKeyId;
    private String accessKeySecret;
    private String signName;
    private String verifyCodeTemplate;
}

3. 在使用的类中启用配置类,并注入

@Component
@EnableConfigurationProperties(SmsProperties.class)
public class SmsUtils {

    @Autowired
    private SmsProperties prop;

    public void test(){
        prop.getAccessKeyId();
    }
}
