Sorry if it's a repeat question. I couldn't find the answer anywhere.
My java application expects a password through an environment variable.
My staging environment doesn't have any password setup. How can I send a null value to the java application through env variable?
export pass=
If I put the above ^ in my ~/.bash_rc file, it isn't working.
EDIT :
I'm using spring & hibernate and taking the value in the XML. Something like the below:
<bean id="myclass" class="mu.package.Myclass">
<constructor-arg index="0" value="${pass}"/>
</bean>
If I replace ${pass} with ${pass:#{null}} to handle null checks with spel, it always takes the null value because the value is not present as a property but as an env variable. Is it possible for ${pass:#{null}} to check both properties & env variable before assigning null value?
Make sure your configuration has defined a PropertyPlaceHolder element in the XML:
<context:property-placeholder />
Then you simply need to make sure that by setting up the system environment variable that it is named exactly the same as your XML configuration expects for it to be translated.

I need to set enviroment variable GOOGLE_APPLICATION_CREDENTIALS at .json format like service-account-file.json but i cant.
I tried this https://elements.heroku.com/buildpacks/buyersight/heroku-google-application-credentials-buildpack and this https://github.com/gerywahyunugraha/heroku-google-application-credentials-buildpack but it is not working.Heroku => java.io.IOException: Error reading credential file from environment variable GOOGLE_APPLICATION_CREDENTIALS, value 'google-credentials.json': File does not exist.
There is no such ways to set environment variable from json file you can use the environment variable like process.env.VARIABLENAME and define that variable name in config
Here i attach the screenshots from where you can define the variable
How do you pass a parameter as an environment variable?
Step 1: Open up user bash file 'vim ~/.bash_profile', write the environment variable and save the file
export TWLIO_NUMBER=+303....
Step 2: In the application porperties file, store the variable
twlio_number=${TWLIO_NUMBER}
Step 3: Import Value in order to use it
import org.springframework.beans.factory.annotation.Value;
#Value("${twlio_number}")
private String TWILIO_NUMBER;
Also, if I hardcode the value in the application properties file, the code works.
Pass those as Java-Opts. It will work.

I am looking for something quick to set the variable in command line.

I need to set applcation properties variable with system variable Ex.

in application.properties file
spring.datasource.username={USER_NAME}
but dind't set.

In your application properties the values should be with lower case and separated by point:
spring.datasource.username=${user.name}
Your environment variable should be as you've mentioned:
USER_NAME=admin
I have a txt file that looks like this:
file: config.txt
property name="java.nio.preferSelect" value="true"
property name="pico.rcp.platform.host" value="172.22.3.11"
property name="pico.rcp.platform.port" value="6790"
I want a windows batch script that will search for "pico.rcp.platform.host" string and change the IP value in that line regardless its value to the passed value in the command line. Like the following:
changeServerTo.bat "172.22.3.1" config.txt
the above script should make the file looks like this:
file: config.txt
property name="java.nio.preferSelect" value="true"
property name="pico.rcp.platform.host" value="172.22.3.1"
property name="pico.rcp.platform.port" value="6790"
and
changeServerTo.bat "172.22.100.221" config.txt
should make the file looks like this:
file: config.txt
property name="java.nio.preferSelect" value="true"
property name="pico.rcp.platform.host" value="172.22.100.221"
property name="pico.rcp.platform.port" value="6790"
and so on.
Your help is much appreciated.
Thanks in advance.
This script just rewrites the entire file and uses the parameter in the output
echo property name="java.nio.preferSelect" value="true" >config.txt
echo property name="pico.rcp.platform.host" value=%1 >>config.txt
echo property name="pico.rcp.platform.port" value="6790" >>config.txt
I am trying to set the property value to DirectorySearch result. It is working fine for absolute path like Path='C:\Program Files\SampleDir'.But it is failing if I use path like Path='[INSTALLDIR]'.
What I observed in case of path=[INSTALLDIR] it is searching for the file in C drive itself.But here [INSTALLDIR] original value is 'C:\Program Files\SampleDir'.If I change the Depth=2 then it is working fine. Whatever the property that I mention in Path attribute it is searching in C drive only.But it is working fine with absolute value of Path like Path='C:\Program Files\SampleDir'.
The code that I am using is
<Property Id='BACKUPFILESEXIST' Secure='yes' Value='ABC'>
<DirectorySearch Id='DirSearch' Path='[INSTALLDIR]' Depth='0' AssignToProperty='yes'>
<FileSearch Id='FileSearch' Name='EncodeDateAction.dll'/>
</DirectorySearch>
</Property>
