我的Spring Boot应用程序中有一个application.yml文件,它不愿意运行。
根据日志,元素simulator.geo.b12、simulator.geo.b13、simulator.geo.b21、simulator.geo.c6、simulator.geo.host未绑定的原因。然而,这个属性是在application.yml中设置的,编译器甚至会返回它的值。
如果有人能帮我解决这个问题,我将不胜感激。
simulator:
geo:
host: http://localhost:8080/
b12: http://localhost:8080/geo/b12
b13: http://localhost:8080/geo/b13
b21: http://localhost:8080/geo/b21
c6: http://localhost:8080/geo/c6和java类
@Getter
@Configuration
@ConfigurationProperties(prefix = "simulator",ignoreUnknownFields = false)
public class VendorSimulatorProperties {
@Value("${simulator.geo.host:http://localhost:8080/}")
private String initUrl;
@Value("${simulator.geo.b12}")
private String geoB12Url;
@Value("${simulator.geo.b13}")
private String geoB13Url;
@Value("${simulator.geo.b21}")
private String geoB21Url;
@Value("${simulator.geo.c6}")
private String geoC6Url;
}当我开始运行应用程序时,我得到了错误消息:

问题是您使用@ConfigurationProperties的方式是错误的。您可以使用@ConfigurationProperties或@Value中的一个,但不能同时使用两者。
该解决方案要么将您的类修复为可用于@ConfigurationProperties,要么删除@ConfigurationProperties注释。
@Getter
@Setter
@Component
@ConfigurationProperties(prefix = "simulator.geo",ignoreUnknownFields = false)
public class VendorSimulatorProperties {
private String host = "http://localhost:8080/";
private String b12;
private String b13;
private String b21;
private String c6;
}您需要修复prefix,它应该是simulator.geo,并且您的属性应该以文件中的键命名。在getter旁边还需要setter。但是,这也需要更改配置的其余部分,以使用新生成的getter。
对你来说,删除@ConfigurationProperties可能更容易,因为你一开始并没有真正使用它们。

我得到了同样的问题,但在我的例子中,这是因为我添加了@AllArgsConstructor,但没有添加@NoArgConstructor。因此,Spring无法创建配置对象(使用默认构造函数),因此它只是跳过处理配置并打印出警告。
例如:
@Getter
@Setter
@AllArgsConstructor
@NoArgConstructor // need to add this if you have @AllArgsConstructor
public class ServerConfiguration {
private String host;
private int port;
