コードが実行されている環境に基づいて、変数を直接アップロードしようとしています。私はいくつかのコードを書き、問題に遭遇しました。私が間違っていることを教えてください。
WebAppInitializer.java
public class WebAppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext sc) throws ServletException {
// Create the 'root' Spring application context
AnnotationConfigWebApplicationContext root = new AnnotationConfigWebApplicationContext();
root.scan("com.configs");
root.getEnvironment().setActiveProfiles("dev");
root.refresh();
// Manages the lifecycle of the root application context
sc.addListener(new ContextLoaderListener(root));
// Handles requests into the application
ServletRegistration.Dynamic appServlet = sc.addServlet("appServlet",
new DispatcherServlet(new GenericWebApplicationContext()));
appServlet.setLoadOnStartup(1);
Set<String> mappingConflicts = appServlet.addMapping("/");
if (!mappingConflicts.isEmpty()) {
throw new IllegalStateException(
"'appServlet' could not be mapped to '/' due "
+ "to an existing mapping. This is a known issue under Tomcat versions "
+ "<= 7.0.14; see https://issues.apache.org/bugzilla/show_bug.cgi?id=51278");
}
}
}
DynamicConfig.java
@Configuration
@Profile("dev")
@PropertySource("classpath:/devel.properties")
public class DynamicConfig {
@Autowired
Environment env;
@Bean
public TestClass testClass(){
TestClass testClass = new TestClass();
testClass.setEnvironment(env.getProperty("environment"));
return testClass;
}
}
TestClassは、環境に基づいた構成から取得される1つのインスタンス変数を持つ単純なクラスです。
TestCase:パッケージcom.tester;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import com.configs.DynamicConfig;
import com.configs.EnvironmentDetector;
import com.tester.TestClass;
public class TestClassTest {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(DynamicConfig.class);
@Test
public void test(){
ApplicationContext context = new AnnotationConfigApplicationContext(DynamicConfig.class);
context.getEnvironment().setActiveProfiles("dev");
context.scan("com.configs");
TestClass test = context.getBean(TestClass.class);
System.out.println(test.getEnvironment());
}
}
今、私はエラーを下回っています

DynamicConfig.javaコードから@profile( "dev")行を削除すると、正常に実行されます。しかし、私はそれが欲しいです。prod用に同様のクラスを作成したいと思います。
助けてください
ありがとう
