java - 导入 java bcrypt 库时遇到问题

Question

我在导入 Spring Security 库时遇到了问题。

这是我的主要课程：

package com.example.test.myfirstproject;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@SpringBootApplication
public class MyFirstProjectApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyFirstProjectApplication.class, args);
    }

    @Bean
    public BCryptPasswordEncoder bCryptPasswordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

还有我的 pom.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

            <artifactId>spring-security-core</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

            </plugin>
        </plugins>
    </build>

</project>

当我尝试在 IntelliJ IDEA 中构建时，出现错误：

java: package org.springframework.security.crypto.bcrypt does not exist

java: cannot find symbol
  symbol:   class BCryptPasswordEncoder
  location: class com.example.test.myfirstproject.MyFirstProjectApplication

我对 BCryptPasswordEncoder 方法使用了自动完成功能，所以应该不会出错。我还尝试更改 pom.xml 文件中安全依赖项的位置，但它也没有帮助。

谢谢您的帮助！
