我从SONAR收到以下错误，我真的不理解以下问题的更改将如何解决，有人可以提供建议吗？
类
@Component
public class CatalogRequestValidator {
public void validateBaseOffersReq(CatalogRequest baseOffersRequest) {
int ZIP_CODE_LENGTH=5;
}
}

在这个上下文中，常量是类中的public static final字段，而不是方法变量。
英文:
a constant in this context is a public static final field in a class, not a method variable.

第一个声纳建议意味着您的本地变量ZIP_CODE_LENGTH的格式不正确，不符合标准。它应该是zipCodeLength（驼峰命名法）。
第二个建议意味着数字5应该被赋值给一个常量。
为了解决这两个建议，只需将本地变量定义为方法之外的常量（私有或公有）。
private static final int ZIP_CODE_LENGTH = 5;
英文:
The first sonar advice means that the format of your local variable ZIP_CODE_LENGTH is wrong, according to standards. It should be zipCodeLength (camelCase).
The second advice means that the number 5 should be assigned to a constant.
In order to solve both advices just define the local variable as a constant outside the method (private or public).
private static final int ZIP_CODE_LENGTH=5;
