java - 限制 application.properties 中的可能值

Question

我想限制 application.properties 可能的值，例如

"condition = "to "YES"和 "NO*"*，到后面是 YES/NO as 在代码中枚举，但我得到“无法将类型 'java.lang.String' 的值转换为所需的 type”。

我怎样才能实现它？

public enum PossibleConditions {
    YES,
    NO
}

Answer 1

Create a new class : MyNewEnumProperties

@ConfigurationProperties(prefix = "enumProperties")
@Getter
public class MyNewEnumProperties{

    private Map<String, Long> enumMapping;

}

Enable ConfigurationProperties to your SpringBootApplication/ any Spring Config via

@EnableConfigurationProperties(value = MyNewEnumProperties.class)

Now add your stuffs in application.properties file like this:

enumProperties.enumMapping.YES=1
enumProperties.enumMapping.NO=0

In your application code autowire your properties like this:

@Autowired
private MyNewEnumProperties properties;
