Dynamic Job Creation in Spring-Batch-How to set bean's property value at runtime

[shyambaishya]

Hi Everyone,

I am new to spring batch and I have a requirement as mentioned below

Requirement :

I have a UI,where the client can enter property details of a Email Action,File Mover Action or File Copy Action,etc.
The client will drag the actions(ex.Email Action,File Mover Action) elements(rectangle box in UI) from the front-end and
enter the properties and do a save.For example,for a File Copy Action element,the user can enter the below:
-- host,file_name,input_location,output_location.
Once the client save the details,we have to generate a Job.xml and execute it in Spring-Batch

snapshot of our Job.xml is like below:
** Where the value="{...}" will come from UI or database

<beans ...>
.......
......
<bean id="copyFile" class="com.email.FileCopyActionTasklet" >
<property name="host" value="{host}"/>
<property name="file_name" value="{file_name}"/>
<property name="input_location" value="{input_location}"/>
<property name="output_location" value="{body_msg}"/>
</bean>
<bean id="dynamicJobParameters" class="com.springbatch.DynamicJobParameters" />
<batch:job id="copyJobId" job-repository="jobRepository" incrementer="dynamicJobParameters">
<batch:step id="step0">
<batch:tasklet ref="copyFile" transaction-manager="jobRepository-transactionManager" />
</batch:step>
</batch:job>
</beans>

Could anybody please help me out ,how can I achieve this.We have to set the property value at runtime.

Please let me also know which below approach shall I take :

1.
GenericApplicationContext genericContext = new GenericApplicationContext();
XmlBeanDefinitionReader xmlReader = new XmlBeanDefinitionReader(genericContext );
xmlReader.loadBeanDefinitions(new FileSystemResource("Job.xml");
genericContext.refresh();

Or

2.the one posted that was posted earlier in this forum :
