Use system variable in spring boot [duplicate]


Use system variable in spring boot [duplicate]



This question already has an answer here:



I have defined a variable in my .bash_profile like this :


export PROFILE=local



Now, I want to get this value in my spring boot application to load different configuration files according to this value.



To do this, I used the annotation @Value but spring can't resolve the value of profile :


@Value("${profile}")
private String environment;



What have I missed ?



EDIT :
This code is launched from a JUnit test inside Eclipse (launched as desktop application)



This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.





did you try ${PROFILE}

You should add spring.profiles.active: ENV_NAME in your properties file. Or you can pass it from command line using -Dspring.profiles.active=ENV_NAME .


spring.profiles.active: ENV_NAME


-Dspring.profiles.active=ENV_NAME



EDIT:



You can also use Map<String, String> getenv = System.getenv(); to get all the environment variables in your code. Then you'll have access to all env variables.


Map<String, String> getenv = System.getenv();





I don't want to have application-dev.properties, application-prod.properties... because I don't want that api keys or other critical information are on our git repo.

You can use jasypt to encrypt values in properties file. Or you can any way send the same profile name through command prompt using -Dprofile=ENV_NAME and get it using @Value

jasypt


profile


-Dprofile=ENV_NAME


@Value



You can do it with the help of this Environment class.


Environment


@Autowired
Environment environment;



and then


String profile = ((StandardServletEnvironment) environment).getSystemEnvironment().get("PROFILE").toString();





It returns a null value :/

System properties and environment variables are two different things!

Export result set on Dbeaver to CSV

The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
