springboot整合springsecurity时报错：

 通过查看报错信息发现都是使用redis的地方报错。项目中是使用redis作为缓存来存放User信息，不整合springsecurity时一切正常，但整合后就出了问题，在网上查了几篇博客发现是在redis序列化存储User对象时出了问题。

重点错误信息：

Could not read JSON: Unrecognized field "enabled" (class com.xyc.community.entity.User), not marked as ignorable (11 known properties: "authorities", "status", "activationCode", "username", "createTime", "type", "id", "email", "headerUrl", "salt", "password"])

可以看到序列化时多了几个字段，这是因为为了整合springsecurity在User类中实现了UserDetails接口。重写了这些方法

 解决办法：

使用@JsonIgnoreProperties注解，可以在User对象在序列化时忽略这些字段

在User类前添加：

@JsonIgnoreProperties({"enabled","accountNonExpired", "accountNonLocked", "credentialsNonExpired", "authorities"})
