SpringBoot常用计量与bean属性校验和进制数据转换规则全面分析

@Data  //lombok省去get/set/toString
@ConfigurationProperties(prefix = "servers") //配置文件的位置，对应的属性注入
public class ServerConfig {
    private String ipAddress;
    private int port;
    private String detail;
//时间
    private Duration serverTimeOut;
//存储空间
    private DataSize dataSize;
}

<!--        提供规范的接口-->
        <dependency>
            <groupId>javax.validation</groupId>
            <artifactId>validation-api</artifactId>
        </dependency>
<!--        对上面接口的实现-->
        <dependency>
            <groupId>org.hibernate.validator</groupId>
            <artifactId>hibernate-validator</artifactId>
        </dependency>

@Data  //lombok省去get/set/toString
//@Component //交给spring容器管理
@ConfigurationProperties(prefix = "servers") //配置文件的位置，对应的属性注入
//②开启校验
@Validated
public class ServerConfig {
    private String ipAddress;
//    ③设置校验规则
@Max(value=9000,message = "最大不能超过9000")
@Min(value=100,message = "最大不能低于100")
    private int port;
    private String detail;
    private Duration serverTimeOut;
    private DataSize dataSize;
}
