JUnit、Spring 上下文和 Webflow

Question

我正在尝试将 JUnit 配置为与 Spring 一起使用，但我不能。 我的问题是它找不到 webflow 文件，因此执行失败。 但是，这对我来说听起来很奇怪，因为我实际上并没有测试 webflow 的东西！我想从控制器开始到数据库。 所以，这就是我正在做的事情

我这样创建一个测试类：

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

    @Test
    ....
}

在类路径中，我插入了 web-application-config.xml 所在的 src/main/resources。这里是它的内容：

<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，我得到以下信息：

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]

也许，您还需要我的 web-flow-config 文件，该文件也位于 src/main/resources 中（而我的流位于 WEB-INF/flows/*/.xml 中，但我也尝试移动到 src/main/resources，结果相同）：

    <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:webflow="http://www.springframework.org/schema/webflow-config"
   xmlns:faces="http://www.springframework.org/schema/faces"
   xsi:schemaLocation="

       http://www.springframework.org/schema/webflow-config http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.3.xsd
       http://www.springframework.org/schema/faces http://www.springframework.org/schema/faces/spring-faces-2.2.xsd">

<!-- Executes flows: the central entry point into the Spring Web Flow system -->
<webflow:flow-executor id="flowExecutor">
    <webflow:flow-execution-listeners>
        <webflow:listener ref="facesContextListener"/>
        <webflow:listener ref="securityFlowExecutionListener" />
        <webflow:listener ref="icefacesFlowListener" />
        <webflow:listener ref="myFlowListener" />
        <webflow:listener ref="myExceptionListener" />
    </webflow:flow-execution-listeners>
</webflow:flow-executor>

<!-- The registry of executable flow definitions -->
<webflow:flow-registry id="flowRegistry" flow-builder-services="facesFlowBuilderServices" base-path="/WEB-INF/flows">
    <webflow:flow-location-pattern value="/**/*-flow.xml" />
</webflow:flow-registry>

<!-- Configures the Spring Web Flow JSF integration -->
<faces:flow-builder-services id="facesFlowBuilderServices" development="true" />

<!-- Installs a listener that creates and releases the FacesContext for each request. -->
<bean id="facesContextListener" class="org.springframework.faces.webflow.FlowFacesContextLifecycleListener"/>

<!-- Installs a listener to apply Spring Security authorities -->
<bean id="securityFlowExecutionListener" class="org.springframework.webflow.security.SecurityFlowExecutionListener" />

<bean id="icefacesFlowListener" class="com.icesoft.spring.security.WebflowListener" />

<bean id="myFlowListener" class="com.infoone.myapp.spring.webflow.AutowiringFlowExecutionListener" />

<bean id="myExceptionListener" class="com.infoone.myapp.exception.MyExceptionListener" />

请考虑我也在使用 JSF 和 Icefaces（我目前不想通过 JUnit 进行测试）。

谢谢！

您的 webflow 文件可能位于 webapp 源而不是 Java 源中，这就是在您的 junit 测试中找不到它们的原因。

我建议让您的 Spring 配置文件更加模块化，然后更改您的测试以仅包含运行测试所需的那些 Spring 配置。
