新建一个maven项目,引入依赖:
<dependencies> <dependency> <groupId>org.apache.solr</groupId> <artifactId>solr-solrj</artifactId> <version>6.3.0</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.9</version> </dependency> </dependencies>
新建helloworld类:
