還需要三個依賴：

        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>2.1.0</version>
        </dependency>
        <dependency>
            <groupId>io.searchbox</groupId
 
>
            <artifactId>jest</artifactId>
            <version>2.0.0</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>
 
5.1.35</version>
        </dependency>

這個基本上就可以了
