elasticsearch 操作依赖jar包添加及应用

1、对应elasticsearch版本为6.2.2，

对应的maven依赖为：

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>transport</artifactId>
            <version>6.4.3</version>
        </dependency>

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>6.4.3</version>
        </dependency>

2、springboot中使用spring-data-elasticsearch连接elasticsearch 6.2.2

        <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-elasticsearch -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
            <version>2.1.7.RELEASE</version>
        </dependency>

需在application.properties中添加

spring.data.elasticsearch.cluster-nodes=127.0.0.1:9300

3、springboot项目中使用jsp所需jar包

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
        </dependency>

        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>

        </dependency>

 需在application.properties中添加

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
