java - 不同模块的注释 spring 上下文的问题

Question

问候。

我基于spring注解配置制作了应用程序。这个应用程序是模块化的，我用 Maven 构建它。 我扫描应用程序以查找一个模块中的配置。

public class ClientUserDAOImplTest {<p></p>

<pre><code>private static UserDAOLocal userDAOLocal;

@BeforeClass
public static void start() {
    beginDate = new Date();
    ApplicationContext ac = new AnnotationConfigApplicationContext("package");
    userDAOLocal = ac.getBean(UserDAOLocal.class);
}
</code></pre>

<p>...
</p>

我在另一个模块中使用@Configuration注释了类。 当我尝试构造 ApplicationContext 时，它失败并显示堆栈跟踪:

小修复。

问题处于测试阶段。因此，其他模块的 jar 已经准备好，并且用于第一个模块测试的 jar 没有创建并作为 .class 文件运行。

Answer 1

如果配置被注释并且位于与“package”不同的基础包中，则上下文将不会拾取它。您需要将应用程序上下文告诉 scan其他包也是如此。

编辑 抱歉错过了异常的内容。你在 jar 上签名的方式不同吗？它们需要使用相同的证书进行签名。
