yml配置

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\

config

@Data
@Configuration
@ConfigurationProperties(prefix = "student")  // 文件上传 配置前缀file.oss
public class MinIOConfigProperties implements Serializable {
    private String red;
}

Test测试类 | ServiceImpl业务逻辑层

@EnableConfigurationProperties(MinIOConfigProperties.class)
@Import(MinIOConfigProperties.class)

这个两个注解都可以完成注入Bean的操作

@SpringBootTest
//@EnableConfigurationProperties(MinIOConfigProperties.class)
@Import(MinIOConfigProperties.class)
class SpringBootTest01ApplicationTests {
    
    @Autowired
    private MinIOConfigProperties minIOConfigProperties;

    @Test
    void contextLoads() {
        // 获取accessKey值
        String accessKey = minIOConfigProperties.getRed();
        System.out.println(accessKey);
    }
}
