Spring Boot REST·application.properties属性导致NullPointerException

[英]Spring Boot REST · application.properties property causing NullPointerException

 原文  2018-04-17 14:35:52  2   1    java/ spring/ postgresql/ hibernate/ spring-boot

问题描述

继续我的最后一个问题 ，我需要添加到application.properties以使ConstraintValidator起作用的相同属性spring.jpa.properties.javax.persistence.validation.group.pre-remove ，当我尝试删除时会导致NullPointerException包含与成员相同类型的列表的实体。 简单的实体被删除就好了。 我什至删除了所有验证，但没有任何改变。

这是一个项目，它是我正在处理的项目的不可操作子集， 这是maven依赖树，这是堆栈跟踪：

我找到了解决方案（某种）。 实际上，我不仅仅包括该财产。 正是org.springframework.validation.Validator的删除导致了javax.validation验证器停止工作。 我发现我需要有一个org.springframework.validation.Validator注册到before|afterCreate|Save|LinkSave|Delete事件中，并且我必须调用复杂实体的链接实体getter或将其更改为fetch = FetchType.LAZY fetch = FetchType.EAGER 。

当我提到NPE发生在读取代码if ( persister.isExtraLazy() ) {的Hibernate代码行时，我的同事给了我建议（请参阅堆栈跟踪顶部）。

看起来不像是正确的做事方式，但目前为止行之有效。 如果有人要补充，我将不胜感激。
