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）

String uuid = UUID.randomUUID().toString();
redisTemplate.opsForValue().set(uuid,code,1,TimeUnit.MINUTES);
Cookie cookie = new Cookie("captcha",uuid);
/*key写入cookie，验证时获取*/
response.addCookie(cookie);
ServletOutputStream outputStream = response.getOutputStream();
//ImageIO.write(bufferedImage,"jpg",outputStream);
VerifyCodeUtils.outputImage(110,40,outputStream,code);
outputStream.flush();
outputStream.close();
}
}
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; /**

*/
@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
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;

import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter; import javax.servlet.FilterChain;
import javax.servlet.ServletException;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List; /**
*
* Description:token的拦截器
* @author huangweicheng
* @date 2019/10/24
*/
@Component
public class JwtAuthenticationFilter extends OncePerRequestFilter
{
@Value("${jwt.header}")
private String tokenHeader; @Value("${jwt.tokenHead}")
private String tokenHead; @Autowired
private UserDetailsService userDetailsService; @Autowired
private JwtTokenUtil jwtTokenUtil; @Autowired
private RedisTemplate redisTemplate; @Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException
{
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)
{
authorityList.add(new SimpleGrantedAuthority(r));
}
String username = jwtTokenUtil.getUserNameFromToken(token);
UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(username,null,authorityList);
authenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(httpServletRequest));
/*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

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。
