The UniqueValues object creates and maintains a list of unique values and the associated counts. UniqueValues is a helper object that provides pixel value information, the unique values and the associated counts, of a raster for RasterUniqueValueRenderer and RasterClassifyColorRampRenderer objects. ...
基于java开发的功能强大、配置灵活的数据库之间的同步工具,和数据产生器一样,均是前段时间因为项目需要编写的小工具,在实际应用场景中,我们经常需要定期将一个数据库的数据同步到另外一个数据库中,常见的一种做法是将源数据库的数据dump为sql文件,然后到目标数据库执行sql文件完成数据库的导入,但是这种方法至少存在以下...

List<User> users = ExcelUtils.readMultipartFile(file, User.class); for(User user : users) { System.out.println(user.toString()); } } 测试效果: 1.2.3 导入解析为对象(字段自动映射) 对于有的枚举数据,通常我们导入的时候,表格中的数据是值,而在数据保存时,往往用的是键,比如:我们用sex=1可以表示...
For example, the class belowgenerates unique identifiers local to each thread. A thread's id is assignedthe first time it invokesThreadId.get() 如下例可知,ThreadLocal 实例是在线程要访问到的类中进行初始化的,且初始化时只要创建ThreadLocal类即可,覆盖inintialValues方法。那么线程在访问该类时即得到一...
