gradle - SpringBoot - @Value is not working during JUnit Test for custom spring config location -


@value not working during junit test when application.yml in location.

fooservicetest

@runwith(springjunit4classrunner.class)     @contextconfiguration(classes = { appconfig.class })     public class fooservicetest {

emailservice in other module

public class emailservice {      @value("${aws.credentials.accesskey}")     private string accesskey;

application.yml

aws:   credentials:     accesskey: xxxxxxxx     secretkey: zxxxxxxxxx

but got:

could not resolve placeholder 'aws.credentials.accesskey' in string value "${aws.credentials.accesskey}"

even added 

-dspring_config_location=/home/foo/other/location/config/

standard spring boot locations

if want spring-boot's application.properties loaded, should launch unit test spring boot (using @springapplicationconfiguration):

@runwith(springjunit4classrunner.class) @springapplicationconfiguration(classes = { appconfig.class }) public class fooservicetest {     @test     public void test...         }

the application.yml should under /config or root in classpath.

see spring doc:

springapplication load properties application.properties files in following locations , add them spring environment:

  • a /config subdirectory of current directory.
  • the current directory
  • a classpath /config package
  • the classpath root

specify additional locations (exemple when executed unit tests)

normally, have used propertysource, though allows load configuration files other locations, not work injected (@value) properties.

you may specify spring.config.location environment variable in static bloc:

@runwith(springjunit4classrunner.class) @springapplicationconfiguration(classes = { appconfig.class }) public class fooservicetest {     static {         //if file not in classpath         system.setproperty("spring.config.location", "file:///path/to/application.yml");          //if file in classpath         //system.setproperty("spring.config.location", "classpath:/path/in/classpath/application.yml");     }      @test     public void test... }

run tests gradle

according this may this: 

$ gradle test -dspring.config.location=file:///path/to/application.yaml

or

$ spring_config_location=file:///path/to/application.yaml gradle test

or add task define systemproperty:

task extconfig {     run { systemproperty "spring.config.location", "file:///path/to/application.yaml" } }  test.mustrunafter extconfig
