Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'userService' is defined

配置SpringJunit4测试时如何配置@ContextConfiguration(locations = { "classpath*:/conf/common/applicationContext.xml" })?????

具体问题描述如下：

分析原因

1、问题报错：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'userService' is defined

2、配置文件

文档结构：

测试代码 MybatisTest1：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:/conf/common/applicationContext.xml" })
public class MybatisTest1 {

    
    private UserService userService;

    @Resource(name = "userService")
    public void setUserService(UserService userService) {
	this.userService = userService;
    }

    @Before
    public void setUp() throws Exception {

    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void test() {
	userService.findAll();
    }
}

配置文件applicationContext.xml：

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			/WEB-INF/conf/*/*.xml 
		</param-value>
	</context-param>
	
	<!-- log4j -->
	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<param-value>
            /WEB-INF/conf/common/log4j.properties
		</param-value>
	</context-param>
	
	<listener>
		<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
	</listener>
	
	<!-- Loads the Spring web application context -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	
	<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
	<servlet>
		<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/conf/common/applicationContext.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

3、分析原因：

配置文件applicationConetxt.xml 找不到，导致注解无法找到userService bean的配置，但不知道（@ContextConfiguration(locations = { "classpath*:/conf/common/applicationContext.xml" })）这个配置该如何修改。
