问题 I am a novice of spring batch. My question is how to catch exceptions with the skip method in spring-batch? As I know, we can use a skip method to skip them when some exceptions happened in spring batch.

And ItemProcessListener did not work either. The code like below:(I use skip method to ignore the exception

问题 I have a web application using spring-batch and I'm now integrating spring-batch-admin for basic administration. The problem is that the jobs configuration files (which are shared with the configuration of the existing application) use properties from files in my application's classpath, but spring-batch-admin's context is not able to load them. The quick solution was to override the placeholderProperties bean in spring-batch-admin just to add my properties files: <bean id=

But the problem with this is

问题 I am quite new to Spring-Batch and I wonder whether there is a way to access the step-id from within an ItemReader or ItemWriter? In my case that would allow switching enum types based on different step-definitions in a single ItemReader implementation. Does anyone know a way to do that? 回答1: Assuming the ItemReader or ItemWriter are step scoped, you can do this: <bean id="flatFileItemReader" scope="step" class="org.springframework.batch.item.file.FlatFileItemReader"> <property name="resource
