SpringBoot整合BCrypt进行密码加密

一. 首先在pom依赖中加入依赖:

 
        <dependency>
            <groupId>org.springframework.securitygroupId>
            <artifactId>spring-security-webartifactId>
        dependency>
        <dependency>
            <groupId>org.springframework.securitygroupId>
            <artifactId>spring-security-configartifactId>
        dependency>

二.在启动类中加入@EnableScheduling注解,获得BCrypt支持:

package com.zzx;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.scheduling.annotation.EnableScheduling;
//获得BCrypt支持
@EnableScheduling
@SpringBootApplication
public class DemoApplication {

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


}

三.模拟获得登录密码:

package com.zzx.test;

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

 * @description: 引入Security依赖默认开启了登录校验，访问API会跳转到登录页,如果只是需要BCrypt加密功能可以在启动类配置@SpringBootApplication (exclude = { org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class })禁用Security相关功能。
 */
public class BCryptTest {
    public static void main(String[] args) {
        //模拟从前端获得的密码
        String password = "123456";
        BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
        String newPassword = bCryptPasswordEncoder.encode(password);
        System.out.println("加密的密码为: "+newPassword);
        boolean same_password_result = bCryptPasswordEncoder.matches(password,newPassword);
        //返回true
        System.out.println("相同代码对比: "+same_password_result);
        boolean other_password_result = bCryptPasswordEncoder.matches("1234456",newPassword);
        //返回false
        System.out.println("其他密码对比: " + other_password_result);
    }
}

运行结果如下:
