When i click on Authentication to add a maven dependency

it shows that there is no results

What I do wrong? Should I install anything before clicking "add maven dependency" ?

Answer 1

Add

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>5.4.0</version>
</dependency>

To your pom.xml
Or just search for another dependency. https://mvnrepository.com/

Answer 2

您需要在 pom 文件中添加 maven 依赖： https : //mvnrepository.com/artifact/org.springframework.security/spring-security-core
