SpringSecurity中授权时fastjson序列化问题

最近在复习Spring Security，复习的鉴权的时候出现问题。26.封装权限信息_哔哩哔哩_bilibili

如果是从B站中看到，直接说问题可能出现的原因：可能是private List<String> authorities;中的权限信息命名不规范，去掉get，A变小写。如果要细看原因请往下看。

 下图是代码中aaaaa是我测试的权限信息集合，故意命名写的不规范，才知道原因。

问题场景：使用Spring Security模拟授权的时候，手动存入几个权限信息，然后正确的访问时出现了问题。

重要的事情放前面说：如果不配置权限集合如果不加@JSONField(serialize = false)注解，解析的时候会报错。

错误日志多不要害怕

 autoType is not support   不支持自动类型

看下面的错误

RedisCache.java是一个自定义的Redis工具类

原来是redis取出数据出现问题，看一下redis中存储的数据。

看到redis数据，怎么这么多字段

我自定义了只有三个字段

user

permission

aaaaa

 user，permisssion都看到出来，但是我的aaaaa怎么没有了，正常，因为使用了@JSONField(serialize = false)注解，不会写入redis中。

postman返回的结果

上面是我第一次遇到的情况，以下是其他测试情况，看完你就知道原因了。

2.将getAuthorities方法的返回值设为null其他不变。

redis中的结果 

发现authorities消失了

数据可以正常解析

但是结果403，但是也正常，因为鉴权的方法的返回值是null。

3.添加authorities字段

 方法正常重写

查看redis数据

发现authorities字段生成

redis数据解析错误

 postman返回的结果

4.给authorities字段加上@JSONField(serialize = false)注解

查看redis数据，发现authorities字段消失

可以获取正常解析redis数据到loginUser

 可以输出结果

我推测是Spring Security会判断authorities字段是否存在如果getAuthorities方法返回值为null或者该字段加上@JSONField(serialize = false)，则不会存入redis中。如下图

其他情况会存入redis中。如下图

但是我们最后要做的是鉴权的时候，方法的返回值不能是null呀。所以只有给authorities字段加上@JSONField(serialize = false)注解才能解决问题。现在突然醒悟了，那我们还要aaaaa这个字段干什么，直接加上authorities字段再给它配个注解，方法里面都写authorities不就解决问题了？是的，确实是这样，因为Spring Security检查的是authorities字段加上@JSONField(serialize = false)注解才会判断要不要写入redis。这个aaaaa这个字段确实多余。

看到这里，大家可能知道问题的原因了，是因为没有定义authorities字段(不能写错！！！)。

查看效果

redis中的数据

 redis解析正常

postman返回数据正常

思考：LoginUser类中字段只写了三个，而且一个加入注解忽略写入redis，为什么还有这么多其他字段？

看一下LoginUser的方法

像不像方法与字段像对应

这样就清晰了，getAuthorities方法应该也可以对应一个字段authorites，如果返回值不为null那个就会有生成字段。存入redis的时候发现这个生成的authorites字段，因为是生成的，没有配置@JSONField(serialize = false)注解，所以会直接存入redis。取出的时候发现没有这个字段，就会报错，就算有这个字段，也解析不出来（重要的事情在文章场景描述的地方）。

这个提醒了我们什么？要规范命名（手动狗头）
