Question

010-10-14 13:22:04 Destroying singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@161509b: defining beans [sqlMapClient,baseDao,StudentDaoImpl,StudentServiceImpl,/student,transactionManager,mytx,dataSource,org.springframework.aop.config.internalAutoProxyCreator,org.springframework.aop.support.DefaultBeanFactoryPointcutAdvisor#0]; root of factory hierarchy

然后,我的ApplicationContext.xml文件配置如下:

    <!-- SqlMapClient的实例配置 -->
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
    <property name="configLocation"  value="classpath:sqlMapConfig.xml"></property>
    <property name="dataSource" ref="dataSource"></property>
</bean>

<!-- BaseDao的配置 -->
<bean id="baseDao" class="pack.java.demo.database.BaseDao">
    <property name="sqlMapClient" ref="sqlMapClient"></property>
</bean> 

<bean id="StudentDaoImpl" class="pack.java.demo.daoimpl.StudentDaoImpl" parent="baseDao"/>

<bean id="StudentServiceImpl" class="pack.java.demo.serviceimpl.StudentServiceImpl">
    <property name="studentDao" ref="StudentDaoImpl"></property>
</bean>

<!-- Struts Action -->
<bean name="/student" class="pack.java.demo.struts.action.StudentAction">
    <property name="studentService" ref="StudentServiceImpl"></property>
</bean>

<!-- DataSource的配置; -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
    <property name="url" value="jdbc:oracle:thin:@localhost:1521:ORCL"></property>
    <property name="username" value="scott"></property>
    <property name="password" value="tiger"></property>
</bean>
    ...省略了,其他的事务代码的配置....

...web.xml配置如下:
<!-- 配置applicationContext.xml文件 -->

contextConfigLocation
classpath:applicationContext.xml

<!-- Listener的配置,监听器 -->

org.springframework.web.context.ContextLoaderListener

请问是哪里配置错误了啊,还是少了一个jar包? 我只有把一个.ibatis2.3.4.8.jar拷贝到WEB-INF/lib目录下。

Answer 1

sqlMapConfig.xml 这里面定义 ibatis 的sql-mapping ，如果没有定义的话最多是找不到配置的ID，应该没有关系，我不知道你的这个dialect.properties实干什么用的，之前我整合的时候没有用到这个呢。

如果你的dao层继承了SqlMapClientDaoSupport，需要在applicationContext.xml中，定义下面的bean

<bean id="sqlMapClientTemplate"
    class="org.springframework.orm.ibatis.SqlMapClientTemplate">
    <property name="sqlMapClient">
        <ref bean="sqlMapClient" />
    </property>
</bean>

继承方法setExtSqlMapClientTemplate。
