junit 不工作@autowired

Question

我收到一个错误自动装配的 bean。在测试类之外它可以工作。做错了什么？如何提升应用程序上下文。甚至指定哪些部分？这是我的代码：

<properties>
      <java-version>1.6</java-version>
      <org.springframework-version>3.1.0.RELEASE</org.springframework-version>      
 </properties>

   <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${org.springframework-version}</version>
        <exclusions>
            <!-- Exclude Commons Logging in favor of SLF4j -->
            <exclusion>
                <groupId>commons-logging</groupId>
                <artifactId>commons-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${org.springframework-version}</version>
    </dependency>


    <dependency>

        <artifactId>spring-orm</artifactId>
        <version>${org.springframework-version}</version>
    </dependency>
  <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.7</version>
        <scope>test</scope>
    </dependency>

  <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>${org.springframework-version}</version>
        <scope>test</scope>
  </dependency>

根上下文.xml

<?xml version="1.0" encoding="UTF-8"?>
  <beans xmlns="http://www.springframework.org/schema/beans"

<import resource="hibernate-config.xml"/>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    //
</bean>

  @RunWith(SpringJUnit4ClassRunner.class)
  @ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/spring/root-  context.xml" })

 public class AdminManagerTest5 {

@Resource(name = "sessionFactory")
private SessionFactory sessionFactory;

@Test
public void t(){
    System.out.print(sessionFactory);

}

}

休眠配置

  bean id="sessionFactory"       class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>

    <property name="configLocation">
        <value>WEB-INF/spring/hibernate.cfg.xml</value>
    </property>

错误

P.S.对不起我的英语

Answer 1

您的sessionFactory 配置指向

<property name="configLocation">
    <value>WEB-INF/spring/hibernate.cfg.xml</value>
</property>

但是WEB-INF/spring 目录没有添加到类路径中，因此 Spring 找不到它。

您需要指定 file: 前缀路径（相对或绝对）或将文件放在类路径中的某个位置。

Answer 2

您正在将 spring-test 4.0 与版本 3.1.0.RELEASE 的其他 spring jar 一起使用。不要那样做。使用 spring-test 3.1.0，或者使用所有其他 spring jar 的 4.0 版本，但不要将不兼容的版本混合在一起。
