您能帮我解决此异常吗？
答案 0 :(得分：0)
在Hibernate Search中看起来像是一个问题，但是您的实体看起来并没有使用它。您是否有使用Hibernate Search的实体？您是在尝试自己初始化Hibernate Search而不是让Quarkus这样做吗？您是否使用了Quarkus Hibernate Search + Elasticsearch扩展？因为仅添加Hibernate Search依赖项将无法工作：您需要使用扩展名。
NPE始终是一个错误，因为如果不支持某些内容，您至少应该有一个更有意义的例外。因此，我们需要深入了解造成这种意外情况的原因。
无论如何，发布完整的复制者（即最小化该问题的应用）可能会有所帮助。
