Java Spring-如何通过@WithUserDetails使用application.properties中的值

Question

I want to use a value from application.properties with the @WithUserDetails() annotation for my tests.

My current code:

@Value("${user.admin}")
private String ADMIN;

@Test
@WithUserDetails(ADMIN)
public void foo() { 
}

displays the error "Attribute value must be constant"

I am using junit4 with spring runner

Answer 1

似乎无法做到这一点，Java编译器不允许这样做，因为它在编译时不将@Value()的值视为常量。

Answer 2

java has built in capabilities to read a .properties file and JUnit has built in capabilities to run setup code before executing a test suite.

java reading properties:

Properties p = new Properties();
p.load(new FileReader(new File("application.properties")));

junit startup documentation

put those 2 together and you should have what you need.

But yes the minimum requirment is you have application.properties file in your test->resources package as well.
