书写测试类

补充知识:JAVA使用Redis所需的MAVEN的POM文件
redis不仅可以通过命令行进行操作,同时redis也可以通过javaAPI进行操作,这是操作redis所需的依赖
<dependencies> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>6.14.3</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.0</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> <!-- <verbal>true</verbal>--> </configuration> </plugin> </plugins> </build>
以上这篇使用java连接Redis,Maven管理操作就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持易盾网络。
