SpringBoot+BCrypt实现简单的密码加密

SpringBoot+BCrypt实现简单的密码加密

首先引入Maven依赖

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-security</artifactId>
</dependency>

配置类

package com.example.demo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/**").permitAll()
                .anyRequest().authenticated()
                .and().csrf().disable();
    }
    @Bean
    public BCryptPasswordEncoder bCryptPasswordEncoder() {
        return new BCryptPasswordEncoder();
    }

}

引入对象

	@Autowired
    BCryptPasswordEncoder bCryptPasswordEncoder;

加密

bCryptPasswordEncoder.encode(”要加密的字符串“)

比较

/**
 *相同返回true,不同返回false
 */
bCryptPasswordEncoder.matches(”未加密的字符串“, “已加密的字符串”)
