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
