我正在努力为我的代码做junit，我使用的是spring 3.2.3，当我使用spring 3.0.2时它工作正常。这个问题与Spring JUnit Test Error相同，但在示例中他说过要使用传递依赖（我不明白它是什么）。我从答案中了解到的是排除旧版本的罐子（解决依赖）。但是，当我从依赖层次结构进行验证时，我发现所有依赖关系都已解析为 3.2.3 版本，并且没有旧版本的依赖关系

我的 pom.xml 是

堆栈跟踪是。

作为 Maven 的新手，有人可以帮我弄清楚我到底需要做什么

我的 Junit 示例类是

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath*:spring-config.xml")
public class HelloWorldTest {


    @Autowired
    public HelloWorld hello1;

    @Test
    public void sayHelloTest(){
         hello1.printHello();
    }
}

我通过检查与我正在使用的 Spring 版本的早期版本相关的 spring 相关的依赖项来解决了这个问题。

例如，我使用的是 3.2.4 版的 spring，在我的依赖项中，我发现 spring-beans 和 spring-expression 使用的是 3.0.4 版。我所做的是将这两个添加到我正在使用的 spring 版本的 pom.xml 依赖项中。在这种情况下添加

 <dependency>
   <groupId> org.springframework </ groupId>
   <artifactId> spring-beans </ artifactId>
   <version> ${spring.version} </ version>
 </ dependency>
 <dependency>
   <groupId> org.springframework </ groupId>
   <artifactId> spring-expression </ artifactId>
   <version> $ {spring.version} </ version>
 </ dependency>

它奏效了。
