使用kennycason.kumo.WordCloud For JAVA 制作词云图-编程知识

官网：https://kennycason.com/posts/2014-07-03-kumo-wordcloud.html

一：添加POM文件

		<!-- 词云 --><dependency><groupId>com.kennycason</groupId><artifactId>kumo-core</artifactId><version>1.27</version></dependency><dependency><groupId>com.kennycason</groupId><artifactId>kumo-tokenizers</artifactId><version>1.27</version></dependency>
