The solution is: add (required = false) after @Autowired, and the red wavy line will disappear
@Autowired(required = false)

After checking, it is found that it is caused by the inconsistent version of the jar package. The version of spring I use is 5.3 13. Before, in order to save trouble, we directly copied other people’s core jar package, and its version was 5.2 6. I changed the versions of these four jar packages to 5.3.0, which is consistent with the spring version 13. The problem is solved
Modified jar package:
There is also a small problem. When using the pointcut expression, there must be a space between * and the following com, otherwise an error will be reported
@Before(value = "execution(* com.testAop.anno.User.add(..))")

Solution:
My flink is flink-1.14.0-bin-scala_2.12.tgz
The above error is basically the pom.xml file messing up
So in the pom.xml file
version should correspond to 1.14.0
flink-streaming-java_ also followed by 2.12
version should correspond to 1.14.0
filnk-clients_ followed by 2.12
version should correspond to 1.14.0
Changed these three places, basically it’s ok
The error that appears is basically that there is no corresponding good version, change it and save it, and then execute
/usr/local/maven/bin/mvn package
That’s it
The following is the pom.xml file that I ran successfully, and the corresponding flink is flink-1.14.0-bin-scala_2.12.tgz
