部署项目，但运行应用程序时出现错误 [错误日志如下]
我做了很多更改，但出现相同的错误，如果使用 @JsonIgnore 则它工作正常但无法获取映射数据。

【解决方案1】：

尝试添加 jackson-core-asl 依赖

<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-core-asl</artifactId>
    <version>1.9.13</version>
</dependency>

【讨论】：

感谢@KLajdpaja 重播，我已经添加但仍然遇到同样的错误。
这条线对我来说似乎很奇怪：private Set<UserOrg> userOrgs = new HashSet<UserOrg>(0);。我会做private Set<UserOrg> userOrgs; 让初始化在休眠的手中
