Question

我正在尝试配置JUnit以使用Spring，但我不能。

我用这种方式创建了一个测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/web-application-config.xml"})
public class MyControllerToTest {
        @Autowired
    private MyController ctr;

    @Test
    ....
}

在classpath中，我插入了web-application-config.xml所在的src / main / resources。其内容如下：

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-3.1.xsd">

<!-- Scans for application @Components to deploy -->
<context:component-scan base-package="com.infoone.mycontrollerpackage"/>

<!-- Imports the configurations of the different infrastructure systems of the application -->
<import resource="webflow-config.xml" />
<import resource="webmvc-config.xml" />
<import resource="data-access-config.xml" />
<import resource="repository-config.xml" />
<import resource="security-config.xml" />

当我作为JUnit运行MyControllerToTest类时，我得到以下内容：

ERROR: org.springframework.test.context.TestContextManager - Caught exception while allowing TestExecutionListener
[org.springframework.test.context.support.DependencyInjectionTestExecutionListener@6419fa] to prepare test instance [com.infoone.myapp.MyControllerToTest@10036f2]

谢谢！

问题是WEB-IN F文件夹在测试时（使用maven）不易（很容易）访问，因为它在测试时位于其他位置。

我的意思是：

运行测试时，在文件夹<project>/target/test-classes中运行已编译的类，WEB-INF文件夹位于<project>/target
当您的班级在<war>/WEB-INF

<war>/WEB-INF/classes

我想说的是，WEB-INF文件夹中资源的相对路径在测试和应用程序之间是不同的。

无论如何，有一个名为spring-test-mvc的弹簧项目，也许您可以使用它或使用您在代码中找到的一些想法。

您需要在file:src内添加@ContextConfiguration并添加@WebAppConfiguration注释。所以测试类看起来应该是这样的：

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = {"file:src:/path.../web-application-config.xml"})
public class MyControllerToTest {
        @Autowired
    private MyController ctr;

    @Test
    ....
}

JUnit和Spring配置
