//设置词的最小长度，这里设置为 2，表示忽略长度小于 2 的词。

//调节词云的稀疏程度，越高越稀疏

// 设置字体 //此处不设置会出现中文乱码 字体设置为仿宋
wordCloud.setKumoFont(new KumoFont(new Font("楷体", Font.BOLD, 25)));
// 设置偏转角，角度为0时，字体都是水平的

//生成词云图路径
UUID uuid = UUID.randomUUID();

//获取编译路径,这里运行后会写到改目录下，可以自定义一个目录，
String targetPath = "./output/";
//String targetPath = this.getClass().getResource("/").getPath()
String path = targetPath+hexString+".png";
// windows目录符号 \\ , 提交到linux 要改成 //
File filePath = new File(targetPath+File.separator);
if(!filePath.exists()){

}

测试运行结果：
生产运行结果：
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
