前端代码
然后把公钥和私钥粘贴到前端的jsencrypt.js文件中注意粘贴的使用要先输入一对双引号使用idea进行粘贴如果使用vscode粘贴就无法出现\n

export function decrypt(txt) {const encryptor new JSEncrypt()encryptor.setPrivateKey(privateKey) // 设置私钥return encryptor.decrypt(txt) // 对数据进行解密
}然后调用登录接口的encrypt方法对密码进行加密 到这里浏览器出现的密码被加密了就说明前端代码就搞定了
后端代码

/*** 登录方法* * param loginBody 登录信息* return 结果*/
PostMapping(/login)
public AjaxResult login(RequestBody LoginBody loginBody) throws Exception
{AjaxResult ajax AjaxResult.success();// 生成令牌String token loginService.login(loginBody.getUsername(), RsaUtils.decryptByPrivateKey(loginBody.getPassword()), loginBody.getCode(),loginBody.getUuid());ajax.put(Constants.TOKEN, token);return ajax;
}到此代码就结束了最终测试登录成功再测试记住密码功能也正常如果下次想要该公钥和私钥记得前后端都要改 这里只是演示了基于若依自带的密码工具进行加密如果想要基于别的工具进行加密解密可以研究一下sm-crypto
