感兴趣的可以先收藏起来还有大家在毕设选题项目以及论文编写等相关问题都可以给我留言咨询希望帮助更多的人

具体实现截图

网站上传的项目均为博主自己收集和开发的质量都可以得到保障适合自己懂一点程序开发的同学使用

为了方便同学们使用我开发了小程序版的名字叫小蔡coding。

同学们可以通过小程序快速搜索和定位到自己想要的程序

代码参考

EntityWrapperUsersEntity().eq(username,

!user.getPassword().equals(password))

{return

tokenService.generateToken(user.getId(),username,

users,

EntityWrapperTokenEntity().eq(userid,

userid).eq(role,

CommonUtil.getRandomString(32);Calendar

cal

{tokenEntity.setToken(token);tokenEntity.setExpiratedtime(cal.getTime());this.updateById(tokenEntity);}

else

{//支持跨域请求response.setHeader(Access-Control-Allow-Methods,

POST,

DELETE);response.setHeader(Access-Control-Max-Age,

3600);response.setHeader(Access-Control-Allow-Credentials,

true);response.setHeader(Access-Control-Allow-Headers,

x-requested-with,request-source,Token,

Origin,imgType,

cache-control,postman-token,Cookie,

Accept,authorization);response.setHeader(Access-Control-Allow-Origin,

跨域时会首先发送一个OPTIONS请求这里我们给OPTIONS请求直接返回正常状态if

(request.getMethod().equals(RequestMethod.OPTIONS.name()))

{response.setStatus(HttpStatus.OK.value());return

false;}IgnoreAuth

handler).getMethodAnnotation(IgnoreAuth.class);}

else

request.getHeader(LOGIN_TOKEN_KEY);/***

不需要验证权限的方法直接放过*/if(annotation!null)

{return

null;if(StringUtils.isNotBlank(token))

{tokenEntity

tokenService.getTokenEntity(token);}if(tokenEntity

null)

{request.getSession().setAttribute(userId,

tokenEntity.getUserid());request.getSession().setAttribute(role,

tokenEntity.getRole());request.getSession().setAttribute(tableName,

tokenEntity.getTablename());request.getSession().setAttribute(username,

tokenEntity.getUsername());return

true;}PrintWriter

null;response.setCharacterEncoding(UTF-8);response.setContentType(application/json;

charsetutf-8);try

response.getWriter();writer.print(JSONObject.toJSONString(R.error(401,

请先登录)));}
