Question

关于ibatis的问题，运行时抛出异常提示SimpleDataSource: Some properties were not set

我的配置大家看看
sqlMapConfig.xml
<sqlMapConfig>

<properties resource="com/ibatis/SqlMap.properties" />

<settings cacheModelsEnabled="false" enhancementEnabled="true"
lazyLoadingEnabled="true" errorTracingEnabled="true" maxRequests="32"
maxSessions="10" maxTransactions="5" useStatementNamespaces="true" />

<transactionManager type="JDBC" commitRequired="true">
<dataSource type="SIMPLE">
<property name="${driver}" value="JDBC.Driver" />
<property name="${url}" value="JDBC.ConnectionURL" />
<property name="${username}" value="JDBC.Username" />
<property name="${password}" value="JDBC.Password" />
<property name="${defaultautocommit}" value="JDBC.DefaultAutoCommit"/>
</dataSource>

</transactionManager>
<sqlMap resource="com/ibatis/Student.xml" />

Answer 1

<property name="${driver}" value="JDBC.Driver" />
<property name="${url}" value="JDBC.ConnectionURL" />
<property name="${username}" value="JDBC.Username" />
<property name="${password}" value="JDBC.Password" />
<property name="${defaultautocommit}" value="JDBC.DefaultAutoCommit"/>
这个地方貌似写反了，name和value的值颠倒下试试。
