There are a couple of drawbacks with using batch files. They are slow to execute because they are run line by line, with MS-DOS closing and reopening the file after each individual line is read. They are also easy to modify, which can create problems. BAT2EXEC (Douglas Boling,PC Magazi...
skip方法我们可以指定我们可以跳过的异常,因为有些异常的出现,我们是可以忽略的。 noSkip方法的意思则是指出现这个异常我们不想跳过,也就是从skip的所以exception当中排除这个exception,从上面的例子来说,也就是跳过所有除FileNotFoundException的exception。那么对于这个step来说,FileNotFoundException就是一个fatal的excepti...
平面文件(flat file)是最多包含二维(表格)数据的任意类型的文件。在 Spring Batch 框架中 FlatFileItemReader 类负责读取平面文件, 该类提供了用于读取和解析平面文件的基本功能。FlatFileItemReader 主要依赖两个东西: Resource 和LineMapper。LineMapper接口将在下一节详细讨论。 resource 属性代表一个 Spring Core Resource...
