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>

?可以单独设置纬度高的词语颜色,字体稀疏度和字体的旋转角度, 都在代码当中,如果有比较好的修改建议,可以评论区留言,一起学习
