java不在unitest中启动spring上下文

Question

我有spring mvc和maven上的web应用程序。 当我执行“mvn clean install”时，我从一些uni测试中得到了nullpointerexception。 这是因为其中一个资源为空，但为什么

统一测试：

package myapp.services.impl

....

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:META-INF/spring/applicationContext.xml"})
@TransactionConfiguration
public class MyServiceImplTest {

    @Resource
    private MyService myService;

    @Transactional
    @Test
    public void someTest() {
        SomeEntity entity = new SomeEntity();
        myService.createSomething(entity);  // THROW - NullPointerException, myService is NULL
        ...
    }
}

pom中的surefire插件。xml:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.4.3</version>
            <configuration>
                <systemProperties>
                    <property>
                        <name>myapp.env</name>
                        <value>test</value>
                    </property>
                </systemProperties>
                <junitArtifactName>org.junit:com.springsource.org.junit</junitArtifactName>
            </configuration>
        </plugin>

和applicationContext。xml:

...
<context:component-scan base-package="myapp.services,myapp.services.impl"/>

<context:property-placeholder location="classpath*:META-INF/spring/common_${myapp.env}.properties"
                              system-properties-mode="OVERRIDE"
                              ignore-resource-not-found="true"/>
....

PS：当我在eclipse中执行这个测试时，以JUnit test的形式运行——执行毫无异常

surefire报告后的堆栈跟踪：

MAVEN输出：

Answer 1

只是一个想法，但是

你说你已经放置了applicationContext。test/resources文件夹中的xml——您是否重新创建了在该目录中定义的目录结构？即test/resources/META-INF/spring/applicationcontext。xml？如果没有，那么applicationcontext将出现在测试类/中，并且不会根据您定义的类路径位置找到。。。如果只是在测试/资源中，请将@ContextConfiguration注释更改为

@ContextConfiguration(locations = {"classpath:applicationContext.xml"})`
