全部，

我正在尝试在 Red5 服务器下运行的应用程序中配置 MyBatis。我在WEB-INF 下创建了一个额外的spring 配置文件red5-ibatis.xml，其中配置了这些bean（如mybatis-spring 用户指南中所述）：

<bean id="hsqldbDataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="org.hsqldb.jdbcDriver" />
    <property name="url" value="jdbc:hsqldb:file:./db/hsqldb/testdb" />
    <property name="username" value="sa" />
    <property name="password" value="" />
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="hsqldbDataSource" />
</bean>

<bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface" value="test.mappers.UserMapper" />
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

当我运行部署了应用程序的服务器时，出现以下异常：

Exception in thread "Launcher:/testapp" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userMapper' defined in ServletContext resource [/WEB-INF/red5-ibatis.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'org.mybatis.spring.SqlSessionFactoryBean' to required type 'org.apache.ibatis.session.SqlSessionFactory' for property 'sqlSessionFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.mybatis.spring.SqlSessionFactoryBean] to required type [org.apache.ibatis.session.SqlSessionFactory] for property 'sqlSessionFactory': no matching editors or conversion strategy found

我不确定，但 Spring 似乎没有看到 SqlSessionFactoryBean 实现了 FactoryBean 接口，因此找不到将其转换为 SqlSessionFactory 的方法？

不管怎样，有什么解决办法吗？

【解决方案1】：

好的，看来我已经解决了。看起来我的应用程序 WEB-INF/lib 目录中有所有 Spring jar，这可能很糟糕，因为它们也在 Red5 lib 文件夹中，所以它们被复制了。在弄乱了我的 ivy.xml 依赖项配置和我的 Eclipse 项目部署程序集设置后，它开始工作了。

基本上我必须从我的 Eclipse 项目中删除标准的 Libraries/ivy.xml [*] 并添加两个单独的，在我的例子中是：ivy.xml [runtime] 和 ivy.xml [compile]。然后在我的 Eclipse 项目属性中，在“部署程序集”设置中，我选择仅部署来自 ivy.xml [runtime] 的依赖项，其中不包含 Spring 库。

没有更多的例外。
