java - executing multiple processing class with Spring batch processing -

-

I'm new to spring batch processing. Just wanted some suggestions so that I can join while reading about spring batch.

My scenario is as follows: I wrote 4 Java classes that read and modify data in Oracle. For example: Class 1 and Class 2 will modify Table 1, Class 3 and Class 4 to modify Table 2.

With spring batch processes, how can we parallel the execution of classes there?

Without knowing what each class does, I can provide a great range of advice, is. It is being said that, if you want to do all, then each class has to execute parallel using the spring batch, the spring batch provides some tools to help with this:

    < Li> Split - Split split flux in spring batch so that the steps can be executed in parallel. In your case, I expected that either two or four flows would be implemented in parallel (if you need to execute class 1 -> class 2 in sequence, but in the same order with class 3 -> class 4 Sequence is required, or if you can just walk all four squares in parallel).
  1. Method InvokingTaskletAdapter - This worksheet implementation provided by Spring Batch allows you to perform a task on a certain bean with a transaction You can wrap existing classes with the Tasklet so that they can easily consume from spring batch.

With the above concepts, you can configure your batch to see something like a job: 

  & lt; Job ID = "Job 1" & gt; & Lt; Split id = "split1" & gt; & Lt; Flow & gt; & Lt; Step id = "split1step1" next = "split1step2" & gt; & Lt; Task ref = "class 1 tasket" /> & Lt; / Step & gt; & Lt; Phase ID = "Split 1 Phase 2" & gt; & Lt; Task ref = = "class 2 toket" /> & Lt; / Step & gt; & Lt; / Flow & gt; & Lt; Flow & gt; & Lt; Step id = "split2step1" next = "split2step2" & gt; & Lt; Task ref = "class 3 tasket" /> & Lt; / Step & gt; & Lt; Phase ID = "Split 2 Phase 2" & gt; & Lt; Task ref = = "square 4 toket" /> & Lt; / Step & gt; & Lt; / Flow & gt; & Lt; / Split & gt; & Lt; / Work & gt; & Lt; Bean id = "Class 1 taskbar" class = "org.springframework.batch.core.step.tasklet.MethodInvokingTaskletAdapter" & gt; & Lt; Property Name = "Target Object" & gt; & Lt; Bean square = "class 1" /> & Lt; / Property & gt; & Lt; Property Name = "Target Method" Value = "Some Method" /> & Lt; / Bean & gt; & Lt; Bean id = "Class 2 taskable" class = "org.springframework.batch.core.step.tasklet.MethodInvokingTaskletAdapter" & gt; & Lt; Property Name = "Target Object" & gt; & Lt; Bean square = "class 2" /> & Lt; / Property & gt; & Lt; Property Name = "Target Method" Value = "Some Method" /> & Lt; / Bean & gt; & Lt; Bean id = "Class 3 taskable" class = "org.springframework.batch.core.step.tasklet.MethodInvokingTaskletAdapter" & gt; & Lt; Property Name = "Target Object" & gt; & Lt; Bean square = "orbit 3" /> & Lt; / Property & gt; & Lt; Property Name = "Target Method" Value = "Some Method" /> & Lt; / Bean & gt; & Lt; Bean id = "square 4 taskable" class = "org.springframework.batch.core.step.tasklet.MethodInvokingTaskletAdapter"> & Lt; Property Name = "Target Object" & gt; & Lt; Bean square = "square 4" /> & Lt; / Property & gt; & Lt; Property Name = "Target Method" Value = "Some Method" /> & Lt; / Bean & gt;

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
