springboot+ es的案例，中报错，

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'elasticsearchTemplate' defined in class path resource 

springboot 版本
<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.4.4</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

改为
<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.2.5.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

运行通过了
