ibatis相关问题

    在开发的sql-map-config.xml文件以及sqlMap。xml文件中，发现了一个问题。就是注释语句必须在<sqlMapConfig>................</sqlMapConfig>的第一个元素中进行，放到其他地方就会解析不成功。
    我用的是myeclipse6.0来开发的，不知道大家有没有遇到过这种问题，调试了一天都没有成功，到处找都没有找到错误的地方，知道第二天将所有的注释删除，才无意中发现，原来是注释的问题。我这里是自己试验的一个小案例：

开发环境：myeclipse+mysql  相关的包都在附件中。

sql-map-config.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN" "http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
  <!-- [b]注意，注释只能写在这里[/b] -->

              maxSessions="10" 
              maxTransactions="5" 
              useStatementNamespaces="false" />
    <transactionManager type="JDBC">
        <dataSource type="SIMPLE">

            <property name="JDBC.ConnectionURL" value="jdbc:mysql://localhost/person" />
            <property name="JDBC.Username" value="root" />
            <property name="JDBC.Password" value="root" />
            <property name="Pool.MaximumActiveConnections" value="10" />
            <property name="Pool.MaximumIdleConnections" value="5" />
            <property name="Pool.MaximumCheckoutTime" value="120000" />
            <property name="Pool.TimeToWait" value="500" />
            <property name="Pool.PingQuery" value="select 1 from sample" />
            <property name="Pool.PingEnabled" value="false" />
            <property name="Pool.PingConnectionsOlderThan" value="1" />
            <property name="Pool.PingConnectionsNotUsedFor" value="1" />
        </dataSource>
    </transactionManager>   
   <sqlMap resource="com/Jdnis/ibatis/map/person.xml" />
</sqlMapConfig>

sqlmap文件的名字person.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://www.ibatis.com/dtd/sql-map-2.dtd">
<sqlMap namespace="Person">
   <!-- 同理注释只能写在这里 -->
   <typeAlias alias="person" type="com.Jdnis.ibatis.model.Person" />
   <statement id="insertPerson" parameterClass="person">
     INSERT INTO persons VALUES(#id#,#firstName#,#lastName#,#birthDate#,#weight#,#height#)
   </statement> 
</sqlMap>

以上两个文件放在包：com.Jdnis.ibatis.map下
