Java Spring 数据休眠搜索引擎
Java Spring Data Hibernate Search Engine
错误：
org.springframework.beans.factory.BeanCreationException：创建名称为 'requestMappingHandlerMapping' 的 bean 在 class 路径资源 [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class] 中定义时出错：调用 init 方法失败；嵌套异常是 java.lang.IllegalStateException：不明确的映射。无法映射 'searchController' 方法
public java.lang.String softuniBlog.controller.SearchController.search(java.lang.String,org.springframework.ui.Model)
to {[/search]}: 已经有'searchController'个bean方法
public java.lang.String softuniBlog.controller.SearchController.index() 已映射。
**我正在尝试为我的博客构建搜索引擎并有 3 个问题。
1) 为什么在应用程序属性中最后 3 行是 "can not resolve"
2) 如何修复我遇到的错误，应用程序正在运行，但是当尝试 url /search?q=someText 时，它会抛出异常：
[处理程序调度失败；嵌套异常是 java.lang.NoSuchMethodError: org.hibernate.engine.spi.SessionDelegatorBaseImpl.(Lorg/hibernate/engine/spi/SessionImplementor;)V] 根本原因
java.lang.NoSuchMethodError: org.hibernate.engine.spi.SessionDelegatorBaseImpl.(Lorg/hibernate/engine/spi/SessionImplementor;)V
3) 如何从输入表单而不是 url
获取搜索查询
please check the code:
搜索输入框
<div id="wrap">
<form action="" autocomplete="on">
<input id="search" name="search" type="text" placeholder="What're we looking for ?"></input>
<input id="search_submit" value="Rechercher" type="submit"></input>
</form>
</div>

老实说，我不明白你的其他问题（你可能应该单独问），但是对于问题 2，我可以告诉你 NoSuchMethodError 很可能是由于你使用了不兼容的带有 Hibernate Search 的 Hibernate ORM 版本。
总结一下：
- Hibernate Search 5.7.0 及更高版本应与 Hibernate ORM 5.2.3 或更高版本一起使用。
- Hibernate Search 5.6.x 及更早版本应与 Hibernate ORM 5.1.x 或更早版本一起使用。
EDIT：你的 pom 似乎包含对 hibernate-entitymanager 的依赖，而你没有为这个依赖设置版本，所以我怀疑你得到一些旧版本。 hibernate-entitymanager 从 Hibernate ORM 5.2 开始不需要使用 JPA，因此您应该尝试删除它。
