我们不快乐的原因之一，是不知道如何安静地待在房间里，心平气和地与自己相处。——亦舒
例如我们需要进行一些自定义配置写到配置文件中
可以使用@ConfigurationProperties注解
package com.ruben.pojo; import com.ruben.enumeration.GenderEnum; import lombok.Data; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; import java.util.List; import java.util.Map; /** * @ClassName: RubenProperties * @Description: ruben配置类 * @Date: 2021/2/16 0016 11:40 * * * @author: <achao1441470436@gmail.com> * @version: 1.0 * @since: JDK 1.8 */ @Data @Component @ConfigurationProperties(prefix = "ruben") public class RubenProperties { private Integer number; private String avatar; private GenderEnum gender; private List<String> hobby; private Map<String, Object> introduce; }
这里枚举GenderEnum
@Getter @AllArgsConstructor public enum GenderEnum { FEMALE("女", 0), MALE("男", 1); private final String name; private final Integer code; }
然后yml中对应配置写法
ruben: number: 4444 avatar: /imgs/oss/2020-06-01/head.jpg gender: male hobby: ["游戏","动漫","编程"] introduce: {"food": "blood","programLanguage": "java"}
我们编写一个测试类测试
package com.ruben; import com.ruben.pojo.RubenProperties; import lombok.extern.slf4j.Slf4j; import org.junit.jupiter.api.Test; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.test.context.SpringBootTest; import javax.annotation.Resource; import java.util.Map; /** * @ClassName: PropertiesDemo * @Description: 我还没有写描述 * @Date: 2021/2/16 0016 11:29 * * * @author: <achao1441470436@gmail.com> * @version: 1.0 * @since: JDK 1.8 */ @Slf4j @SpringBootTest public class PropertiesDemo { @Resource private RubenProperties rubenProperties; @Test public void test() { log.info(rubenProperties.toString()); } }
运行结果
