springboot security+redis+jwt+验证码 登录验证

概述

　　基于jwt的token认证方案

 验证码

　　框架的搭建，可以自己根据网上搭建，或者看我博客springboot相关的博客，这边就不做介绍了。验证码生成可以利用Java第三方组件，引入

       <dependency>
            <groupId>com.github.penggle</groupId>
            <artifactId>kaptcha</artifactId>
            <version>2.3.2</version>
        </dependency>

配置验证码相关的属性

@Component
public class KaptchaConfig
{
    @Bean
    public DefaultKaptcha getDefaultKaptcha()
    {
        DefaultKaptcha defaultKaptcha = new DefaultKaptcha();
        Properties properties = new Properties();
        /*是否使用边框*/
        properties.setProperty("kaptcha.border","no");
        /*验证码 边框颜色*/
        //properties.setProperty("kaptcha.border.color","black");
        /*验证码干扰线 颜色*/
        properties.setProperty("kaptcha.noise.color","black");
        /*验证码宽度*/
        properties.setProperty("kaptcha.image.width","110");
        /*验证码高度*/
        properties.setProperty("kaptcha.image.height","40");
        //properties.setProperty("kaptcha.session.key","code");
        /*验证码颜色*/
        properties.setProperty("kaptcha.textproducer.font.color","204,128,255");
        /*验证码大小*/
        properties.setProperty("kaptcha.textproducer.font.size","30");
        properties.setProperty("kaptcha.textproducer.char.space","3");
        /*验证码字数*/
        properties.setProperty("kaptcha.textproducer.char.length","4");
        /*验证码 背景渐变色 开始*/
        properties.setProperty("kaptcha.background.clear.from","240,240,240");
        /*验证码渐变色 结束*/
        properties.setProperty("kaptcha.background.clear.to","240,240,240");
        /*验证码字体*/
        properties.setProperty("kaptcha.textproducer.font.names", "Arial,微软雅黑");
        Config config = new Config(properties);
        defaultKaptcha.setConfig(config);
        return defaultKaptcha;
    }
}

配置相应的配置接口就能生成验证码，但是这钟样式有点不好看，如果自定义还非常麻烦，索性

将生成的验证码放置到redis里，登录时候，从cookie取值，过滤器拦截验证（仅限PC端）

尝试访问接口，生成的验证码是不是比组件生成的验证码好看多了。

验证码过滤器

验证码生成后，哪些地方需要用到验证码，配置对应的路径，设置过滤器进行过滤，过滤器继承OncePerRequestFilter，这样能够确保在一次请求只通过一Filter，而不需要重复执行，对应的路径没有正确的验证码抛出一个自定义的异常进行统一处理。

注解很多都解释清楚，就不过多介绍了。因为security已经将实现登陆的功能封装完成，需要我们做的其实并不多，我们要做仅是查找用户，将查询用户的信息，包括密码，角色等等交给UserDtails，然后在配置里进行自定义验证（可以是md5或其他加密方式），持久层用的是jpa

角色类Role

import io.swagger.annotations.ApiModel;
import lombok.Data;

import javax.persistence.*;

@Entity
@Data
@ApiModel
@Table(name = "t_sys_role")
public class SysRoleVo extends SysBaseVo
{
    @Id
    @GeneratedValue
    @Column(name = "role_id")
    private int roleId;

    @Column(name = "role_name")
    private String roleName;
}

因为我喜欢把相同的属性抽出来，所以定义了一个基类，也可以不这么干

import io.swagger.annotations.ApiModel;
import lombok.Data;

import javax.persistence.*;

@Entity
@Data
@ApiModel
@Table(name = "t_sys_role")
public class SysRoleVo extends SysBaseVo
{
    @Id
    @GeneratedValue
    @Column(name = "role_id")
    private int roleId;

    @Column(name = "role_name")
    private String roleName;
}

接下来就简单多了，只需要在定义一个实现类去实现UserDetailService，基本的登录其实就完成了。

import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

/**
 * 
 * Description:账户详情信息
 * @author huangweicheng
 * @date 2019/10/21   
*/ 
@Service
public class SysUserDetailsServiceImpl implements UserDetailsService
{
    @Resource
    private SysUserRepository sysUserRepository;

    @Override
    public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException
    {
        SysUserVo sysUser = sysUserRepository.findByUserName(userName);
        if (sysUser == null)
        {
            throw new UsernameNotFoundException(userName);
        }
        return sysUser;
    }
}

 现在我们设置token过滤，请求接口没有token或者token已经过期，就会跳到登录页面

    @Override

        String token = httpServletRequest.getHeader(this.tokenHeader);
        if (token != null && jwtTokenUtil.validateToken(token))
        {
            String role = jwtTokenUtil.getRolesFromToken(token);
            String[] roles = role.split(",");
            List<GrantedAuthority> authorityList = new ArrayList<>();
            for (String r : roles)
            {

            /*权限设置*/
            SecurityContextHolder.getContext().setAuthentication(authenticationToken);
        }
        filterChain.doFilter(httpServletRequest,httpServletResponse);
    }
}

现在验证的核心内容都已经完成，写几个接口测试下。

HomeController类

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HomeController
{
    @RequestMapping("/admin/test2")
    @ResponseBody
    public String admin2()
    {
        return "ROLE_ADMIN";
    }

}

HwcController类

@Controller
public class HwcController
{
    @GetMapping("/hwc/test")
    @ResponseBody
    public String test()
    {
        return "ROLE_USER";
    }
}

用postman测试一下，没token匿名访问

 获取验证码后，将验证码写入cookie里，输入账号密码，登录

登录成功

token在放在header里

 

有token，没权限访问

 有权限有token访问

 补充

总结

jwt的token本应该是无状态的认证的，但没到过期时间这个token都是可用的，没法控制，在这期间如果被盗取，将会产生严重后果，所以引入redis控制状态。而且这还是不够严谨，应该进一步引入https的认证。增加信息的安全性，这只是一个demo，如果有需要，请留言，将会整理到码云或github上提供下载。
