當springsecurity出現SerializationException問題

01 異常發生場景

• 當我使用springsecurity時，登錄成功后攜帶token訪問接口出了問題

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 問題發生的原因

• 日志說的很清楚，無法讀取 JSON：無法識別的字段
• 原本我以為是存儲時格式有問題
• 但是檢查了工具類和存儲時的代碼，確定了沒問題
• 后來發現我的實體類沒有序列化

03 解決方式

• 在實體類上加上注解@JsonIgnoreProperties(ignoreUnknown = true)

@Data
@NoArgsConstructor
@AllArgsConstructor
@JsonIgnoreProperties(ignoreUnknown = true)
public class LoginUser implements UserDetails {

    private MsUser msUser;
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return null;
    }

    @Override
    public String getPassword() {
        return msUser.getPassword();
    }

    @Override
    public String getUsername() {
        return msUser.getUsername();
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
}
