使用BCrypt加密密码

1.添加依赖

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

2.添加上述依赖后，所有地址都被spring security控制了

需要写一个配置类来允许所有地址可访问

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter{
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/**").permitAll()
                .anyRequest().authenticated()
                .and().csrf().disable();
    }
}

3.在启动类将BCrypt加入spring容器

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

4.注入BCrypt

　　@Autowired
    private BCryptPasswordEncoder bCryptPasswordEncoder;

5.加密密码

user.setPassword(bCryptPasswordEncoder.encode(user.getPassword()));
