java - Spring，无法在测试中加载ApplicationContext

标签 java spring applicationcontext spring-test

我有以下 web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app
        version="3.0"
        xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="
        http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd
        ">

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <listener>
        <listener-class>
            org.springframework.web.context.request.RequestContextListener
        </listener-class>
    </listener>

    ...
    <listener>
        <listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
    </listener>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/applicationContext.xml</param-value>
    </context-param>
    ...

    <!-- Spring MVC -->
    <servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>WEB-INF/webContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

因此我从 web.xml 加载了两个配置文件:

applicationContext.xml 和 webContext.xml

我将这些文件复制到 resources/META-INF 并使用以下签名编写集成测试:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:META-INF/applicationContext.xml", "classpath:META-INF/webContext.xml"})
public class OwnerTerminalsControllerTest {

当我尝试执行测试中的任何方法时，我看到如下错误:

对我来说，两个配置看起来一样，我不知道为什么不能从测试上下文中加载

附言

在 applicatioContext 中，我有以下几行:

<import resource="classpath:META-INF/dataContext.xml"/>
<import resource="classpath:META-INF/restTemplateContext.xml" />
<import resource="classpath:META-INF/securityContext.xml"/>

最佳答案

在 dataContext.xml 中，SessionFactory bean 总是在配置文件下声明，而您的测试配置没有声明任何一个，因此该 bean 永远不会加载到应用程序上下文中，导致 No qualifying bean ... 错误。您应该声明一个有效的配置文件:

@RunWith(SpringJUnit4ClassRunner.class)
@ActiveProfiles(profiles = "test")
@ContextConfiguration(locations = {"classpath:META-INF/applicationContext.xml", "classpath:META-INF/webContext.xml"})
public class OwnerTerminalsControllerTest {
