How to set default context-param values for ServletContextPropertyPlaceholderConfigurer? - spring

How to set default boolean values with ServletContextPropertyPlaceholderConfigurer? For example, I want property to have false value if it is not set as <context-param>

you can always define a default value for every place where the property configurere "inject" some value.
The default synax is ${propertyName:default}
So for example:

Is there a way to configure 2 property system in same #Value ins spring boot?

I trying to use 2 different property files with the same parameters which every parameter is describing the same property for example:
NewsPaperConsumer.properties, MarketConsumer.properties when every file have the same parameters.
My aim is to use the separated way to make the configuration files more readable but at the progromatic side union them to one hash map for example:
NewPaperConsumer and MarketConsumer have the parameter serverAddress so I'll get it by:
#Value("${serverAddress}")
private HashMap<String,String> serverAdresses;
how I change the way the system property save the parameter (instead of assign the value to string that It will assign it to hash map - {"key" : "value }

How to set a property in ruby datamapper that is a function of another property of the same object?

I want to add two new properties to a ruby datamapper model, one that is a date cast of a timestamp property and another that is a value from another object connected through a unique key.
So for the first case I have
property :date, DateTime
and I want to add another
property :date_date, Date
that by default will be equal to date.to_date
You should see the docs: https://datamapper.org/docs/properties.html
Specifically the sections on "Available Types" and "Setting default values".
You can do it like this:
property :date_date, Date, default: -> do |obj, prop|
obj.date.to_date
end
You can alternatively set it through a callback (https://datamapper.org/docs/callbacks.html), for example:
property :date_date, Date
before_save :set_date_date
def set_date_date
self.date_date = date.to_date
end
Note it works basically the same way in Rails' ActiveRecord as well.

__V for property variable in jmeter

I have JMX structure such as,
ThreadGroup-1
Set propertyVariable-Content_0,Content_1,Content_3 etc
ThreadGroup-2
LoopController
Counter-counterNum
HTTPRequest--use PropertyValue as ${__V(__P(Content)_${CounterNum})}
above variable is not fetching value.
Got stuck on how to use __V for this case as it has property variable.
can someone explain me how to use __V when we have property variable.
You don't need __V() function here, you can access property value using __P() function directly like:
${__P(Content_${CounterNum},)}
Demo:
In case of malfunction double check that you're really setting the properties values using Debug Sampler and View Results Tree listener combination
you need to use this
${__V(MainVriableName_${CounterNo})}
1) Add Loop Controller
2) Under Loop Counter -> Add Counter (Starting value= 1, Increment = 1, Maximun value = ${MainVriableName_matchNr} and Exported Variable Name = CounterNo
3) After in the below Request(s) use ${__V(MainVriableName_${CounterNo})}
this works fine.

Spring propery placeholder not working as expected if defined twice

I have defined 2 property placeholder conf with same order .Behaviour what i was found is that if i define a property in the 2nd file with default value it is not picking from the file.if i didnot specify the default value it is taking from the file.can anybody help.``
1)
config.properties
userName=Jithin
2)
configtext.properties
charlength=256
Program:
#Value("${charlength:128}")
private String charLenght;
If i specify the default values as 128, charLenth field is assigned with 128
If i am not specifying the default value. ie:
#Value("${charlength}")
private String charLenght; In this case, it is reading from the property file and assigned with 256

jxls forEach tag : how to define local variables?

Can we define local variables in jxls which can be used to set an incrementing count for a column.
For eg: Consider the following
<jx:forEach items="${myList}" var="myVar">
-- i need to define a local integer variable here which will have an initial value as 0
-- and i will increment it and display in the output xls's first column
</jx:forEach>
Basically my requirement is to have somekind of local variable declaration in jxls code which i would increment and display in xml.
Any other alternatives are welcome.
Regards,
Rahul
jx:forEach tag support varStatus attribute which defines a name of loop status object which will be passed into bean context for each iteration. The loop status object is an instance of LoopStatus class which has single 'index' property identifying the index of the current item in the collection being iterated
<jx:forEach items="${employees}" var="employee" varStatus="status">
| ${status.index} | ${employee.name} | ${employee.payment} | ${employee.bonus}
</jx:forEach>
Figured it out.... We can use <jx:out expr="hssfRow.getRowNum()" /> in the column where we want to display the numbering. We can keep the above piece of code inside <jx:forEach items="${myList}" var="myVar"> tag
