统一测试类与config类

yml

student:red: dou

config 

@Configuration注解 与 @Component注解都可以。

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

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

test 

@SpringBootTest
class SpringBootTest01ApplicationTests {@Autowiredprivate MinIOConfigProperties minIOConfigProperties;@Testvoid contextLoads() {// 获取accessKey值String accessKey = minIOConfigProperties.getRed();System.out.println(accessKey);}}

1. 启动类注入Bean

@SpringBootApplication
public class SpringBootTest01Application {public static void main(String[] args) {SpringApplication.run(SpringBootTest01Application.class, args);}@Beanpublic MinIOConfigProperties minIOConfigProperties() {return new MinIOConfigProperties();}}

2.启动类扫描@ComponentScan

@ComponentScan(basePackages = "com.ma.config")
@SpringBootApplication
public class SpringBootTest01Application {public static void main(String[] args) {SpringApplication.run(SpringBootTest01Application.class, args);}}

3.启动类@EnableConfigurationProperties

@SpringBootApplication
@EnableConfigurationProperties(MinIOConfigProperties.class)
public class SpringBootTest01Application {public static void main(String[] args) {SpringApplication.run(SpringBootTest01Application.class, args);}}

4.启动类@Import

@SpringBootApplication
@Import(MinIOConfigProperties.class)
public class SpringBootTest01Application {public static void main(String[] args) {SpringApplication.run(SpringBootTest01Application.class, args);}}
