I have a BusinessException class below:
@Getter
public class BusinessException extends RuntimeException {
private final Integer code;
private final String msg;
public BusinessException(Integer code, String msg) {
super(msg);
this.code = code;
this.msg = msg;
}
/**
* assert-style check
*/
public static void failBuild(boolean isError, Integer errorCode, String message) {
if (isError) {
throw new BusinessException(errorCode, message);
}
}
@Override
public String toString() {
return String.format("BizErrorCodeException:[code=%s,msg=%s]", code, msg);
}
}
and I invoke BusinessException#failBuild like this in the other class:
@Getter
public class MyService {
public void test(Order dto) {
BusinessException.failBuild(Objects.isNull(dto), ErrorCodeEnum.PARAM_FAIL);
//SonarLint' s FP here: dto is nullable here
log.info("orderId: {}", dto.getId())
}
}
There are two java source code files: BusinessException.java and MyService.java
My software information:
- IDEA 2021.3
- SonarLint 6.3.1.40948
I found some discuss in the community or stackoverflow, I know the symbolic execution engine. I want to know how to avoid this FP? Is there some jsr305’s annotations I can used?
