sqlMapConfig文件如下：：
<sqlMapConfig>
<transactionManager type="JDBC" commitRequired="false">
<dataSource type="DBCP">
<property name="JDBC.Driver" value="${HDBDriver}" />
<property name="JDBC.ConnectionURL" value="${HDBURL}" />
<property name="JDBC.Username" value="${HDBUserName}" />
<property name="JDBC.Password" value="${HDBPassword}" />
<property name="Pool.MaximumActiveConnections" value="20"/>
<property name="Pool.MaximumIdleConnections" value="5"/>
<property name="Pool.MaximumWait" value="60000"/>
<property name="Pool.LogAbandoned" value="true"/>
<property name="Pool.RemoveAbandoned" value="false"/>
<property name="Pool.RemoveAbandonedTimeout" value="50000"/>
</dataSource>
</transactionManager>

Answer 1

错误初始化的TransactionManager 。不能实例TransactionConfig 。问题在配置文件中，如果用到Spring的话在Spring中配置的事务管理器，如果有配置数据源的话在检查一下，往回推！

强制类型转换到两个包下JdbcTransactionConfig到TransactionConfig的异常 查下代码或者spring的配置文件
