spring boot如何在plan java应用程序中使用StandardEnvironment

Question

当我阅读spring源代码时，我发现类StandardEnvironment。我想在plan java应用程序中使用StandardEnvironment，如下所示

@Test
public void test() {

     StandardEnvironment enviment=new StandardEnvironment();
            System.out.println(enviment.getProperty("Pk")==null?"not find":enviment.getProperty("Pk"));


}

java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=test], {ExactMatcher:fDisplayName=test(com.dominos.cloud.user.dao.EnvimentTest)], {LeadingIdentifierMatcher:fClassName=com.dominos.cloud.user.dao.EnvimentTest,fLeadingIdentifier=test]] from org.junit.internal.requests.ClassRequest@2acf57e3
