当springsecurity出现SerializationException问题

01 异常发生场景

• 当我使用springsecurity时，登录成功后携带token访问接口出了问题

org.springframework.data.redis.serializer.SerializationException: Could not read JSON: Unrecognized field "username" (class com.example.demo.entity.LoginUser), not marked as ignorable (2 known properties: "msUser", "authorities"])

02 问题发生的原因

• 日志说的很清楚，无法读取 JSON：无法识别的字段
• 原本我以为是存储时格式有问题
• 但是检查了工具类和存储时的代码，确定了没问题
• 后来发现我的实体类没有序列化

03 解决方式

• 在实体类上加上注解@JsonIgnoreProperties(ignoreUnknown = true)

@Data
@NoArgsConstructor
@AllArgsConstructor
@JsonIgnoreProperties(ignoreUnknown = true)
public class LoginUser implements UserDetails {private MsUser msUser;@Overridepublic Collection<? extends GrantedAuthority> getAuthorities() {return null;}@Overridepublic String getPassword() {return msUser.getPassword();}@Overridepublic String getUsername() {return msUser.getUsername();}@Overridepublic boolean isAccountNonExpired() {return true;}@Overridepublic boolean isAccountNonLocked() {return true;}@Overridepublic boolean isCredentialsNonExpired() {return true;}@Overridepublic boolean isEnabled() {return true;}
}
