我正在尝试使用 MyBatis 和 Spring 构建我的第一个 mvn 项目。

<dependency>
        <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.0.5</version>
</dependency>
<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.0.1</version>
</dependency>

以下是项目结构：

my-project
|
|_ conf --> spring-conf.xml
|
|_ main 
    |
    |_ java
    |
    |_ resources
           |
           |_ persistence --> mybatis.xml

当我运行一个 junit 到它们与数据库的连接时，它给出了以下内容：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'databaseManager' defined in file [O:\WORKSPACE\my-project\conf\spring-conf.xml]: 
Cannot resolve reference to bean 'databaseManagerTarget' while setting bean property 'target'; nested exception is org.springframework.beans.factory.BeanCreationException:

对 mybatis.xml 的引用在 spring-conf.xml 中定义如下

    <!-- SESSION FACTORY -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:resources/persistence/mybatis.xml" />  
</bean>

任何想法，请帮助。

似乎您在测试运行期间错过了类路径中的 mybatis.xml。尝试添加到 pom（我不确定确切的路径）：

<build>
    <testResources>
        <testResource>
            <directory>resources/persistence/mybatis.xml</directory>
        </testResource>
   </testResources>
</build>
