Set Use value application.properties from another properties

Question

I am building a spring boot application, can application.properties value get from another property

I have an application.properties like this

spring.datasource.url= jdbc:oracle:thin:@//localhost:1521/test
org.quartz.dataSource.qDS.URL=jdbc:oracle:thin:@//localhost:1521/ORCL

can Spring boot doing like this ?

db.connections.url=jdbc:oracle:thin:@//localhost:1521/test
spring.datasource.url= db.connections.url
org.quartz.dataSource.qDS.URL=db.connections.url

No, but in a same property file. but if it's not possible, it's okay to read from another file, as long as it's not configured in the java class. — Konsultan IT Bandung, Jul 11 '20 at 04:58

I've solved with adding ${...} to set value from other property

this is how I solved :

app.dbconnectionstring=jdbc:oracle:thin:@//localhost:1521/ORCL

#spring default datasource
spring.datasource.url=${db.dbconnectionstring}

#quartz datasource
org.quartz.dataSource.qDS.URL=${app.dbconnectionstring}

Cool! I got late by 23 seconds. But glad that you got the solution. – Amit kumar Jul 11 '20 at 05:22
That is the right way. More robust (no file name depending) and more readable. – davidxxx Jul 11 '20 at 06:46

Spring properties that depend on other properties can be defined like below in your Class:

@Value("#{myFile:${myProperties}/myfile.txt}")
private String myFileName;

Spring can combine properties

myDir=/path/to/mydir

myFile=${myDir}/myfile.txt

Properties file :

myDir=/path/to/mydir

Set Use value application.properties from another properties
