SpringSecurityOAuth使用JWT Token

⒈JWT？

　　JWT（Json Web Token），是Json的一个开放的Token标准。

　　　　1，自包含，SpringSecurityOAuth的默认Token是UUID的一个随机的无意义的字符串，并不包含任何信息，信息是被单独存放的，我们还需要通过这个令牌从单独存放信息的存储那里获取信息，所以说SpringSecurityOAuth的默认Token比较依赖于存储，一旦存储信息的存储那里出现了故障，那么这个令牌就毫无用处了。而JWT Token中是包含有意义的信息的，当我们的系统拿到这个令牌以后，我们可以直接解析这个令牌来获取有用的信息。

　　　　2，密签，我们可以对发出去的令牌进行签名（指令牌被人篡改我们可以获知）

　　　　3，可扩展，Token中的信息我们可以根据业务需求进行扩展。
