Question

在我的应用程序中，存在具有一对多关系的实体。当我查询父项时，孩子们也会被提取。我想只获取父级。我尝试将fetchType添加为Lazy，但它仍会抓取孩子。实体如下：

家长实体

Answer 1

确保在记录根实体时，其toString（）实现不会显式或隐式迭代子集合：
```
logger.info("List : " + instituteInfoMaster);
```
如果Hibernate Session仍处于打开状态，并且您尝试将根序列化为JSON，则在访问子集合时，将初始化它，并且还将获取每个关联的子节点。要证明这一点，请尝试将@JsonIgnore添加到子集合中并再次检查。
尝试在儿童系列上添加@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)，让2nd level collection cache为您处理。
