@ConfigurationProperties注解对数据的自动封装
@ConfigurationProperties注解对数据的自动封装
@ConfigurationProperties可以对基本数据类型实现自动封装,可以封装格式为yyyy/MM/dd的日期
测试代码:
package aat;
import java.util.Date;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import lombok.Data;
/**
* 使用@ConrigurationProperties注解封装配置文件中的数据
*/
@Component
@Data
@ConfigurationProperties(prefix="author")
public class TestProperties {
private String name;
private Integer age;
private String phone;
private Boolean isboy;
private Float ppt;
private Date birthday;
private Date birthday1;
private Date birthday2;
}配置文件信息:
author:
name: xixihaha
age: 1112
phone: 1234556666
isboy: true
ppt: 1.3
# birthday: 2018-1-1
# birthday1: 20180101
# birthday2: 2018/1/1如果封装日期类型,需要格式为 yyyy/MM/dd,可以自动封装,如果为yyyy-MM-dd或者为yyyyMMdd都会报错:
