here I am unable to find @PostContructor

need @PostConstructor

CodePudding user response：

Assuming that you are referring to @PostConstruct here.

Note that both the @PostConstruct and @PreDestroy annotations are part of Java EE. Since Java EE was deprecated in Java 9, and removed in Java 11, we have to add an additional dependency to use these annotations:

<dependency>
    <groupId>javax.annotation</groupId>
    <artifactId>javax.annotation-api</artifactId>
    <version>1.3.2</version>
</dependency>
