无法解析 XML-config spring 应用中的占位符
Could not resolve placeholder in XML-config spring app
我是 spring 的初学者。我在 SO 上阅读了许多类似的标题问题，要么它们不适合我，要么不是那种类型的配置，我不明白哪里出了问题。
我正在使用 Gradle 在 Intellij Idea 中编写一个简单的 spring 应用程序。一切都运行良好，直到我决定从 .properties 文件中读取一些值。 xml-config 文件和 .properties 文件都在资源中。
我创建了一个简单的 junit 测试。 LoginService 的实现是有效的，因为在 xml 中硬编码电子邮件和密码时，测试已经通过。

测试class（展示我如何阅读xml）：
import com.doszke.isf.java.spring.service.Login;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import static org.junit.Assert.assertNotNull;
public class MyDocumentsLoginTest {
private static final String EMAIL = "test@mydocuments.com";
private static final String PASS = "test123";
private static final String SUCCESS = "Authorized";
private static final String FAILURE = "Authorization failed";
private ClassPathXmlApplicationContext context;
@Before
public void setup(){
context = new ClassPathXmlApplicationContext("META-INF/spring/MyDocuments-config.xml");
}
@Test
public void testLogin(){
Login login = context.getBean(Login.class);
assertNotNull(login);
System.out.println(login.isAuthorized(EMAIL, PASS) ? SUCCESS : FAILURE);
}
}
我的项目结构是这样的：
@更新： env_dev.properties 文件：
user.email=test@mydocuments.com
user.password=test123
在applicationContext.xml中，改为：
<?xml version="1.0" encoding="UTF-8"?>

这绝对可以解决问题。请将资源文件夹添加到类路径。
