Not annotated parameter overrides @NonNullApi parameter

phenomenon

idea warning, just like this

Not annotated parameter overrides @NonNullApi parameter

Similar to this:

Not annotated parameter overrides @NotNull parameter

This warning looks very unfriendly, it seems to make you add the @NotNull annotation or @NonNullApi, but it is useless!!!
Although it's just a warning, OCD is hard!!!

Problem description

The error message is

Not annotated parameter overrides @NonNullApi parameter

Literal translation: @NonNullApi parameters are rewritten by parameters that are not annotated
This hint means that because the package of the overridden method is annotated with this @NonNullApi, the method parameters also need to be annotated
Prompt NotAnnotated parameter means that the parameter is not annotated. As for the annotation prompt, it is not mentioned.

Solutions (two)

Use "javax.annotation.Nonnull" annotation to solve

Add @Nonnull annotation directly to the parameter

import javax.annotation.Nonnull;@[email protected] class ScheduledConfigurer implements SchedulingConfigurer {@Overridepublic void configureTasks(@Nonnull ScheduledTaskRegistrar taskRegistrar) {taskRegistrar.setScheduler(taskExecutor());}}

can be solved by using "org.springframework.lang.NonNullApi" annotation

Add @NonNullApi annotation to the package in the package-info.java file

@NonNullApipackage com.jswdwsx.configurer;import org.springframework.lang.NonNullApi;

Let me introduce myself first. The editor graduated from Shanghai Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Alibaba in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is also very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
