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

|---------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | hljs java 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

|---------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 10 11 | hljs java @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

|---------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 | hljs yaml 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

|---------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | hljs java 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
