org.xml.sax.SAXParseException: The content of element type “sqlMapConfig” must match “(properties?,s

最近在学习ibatis,但是在配置文件的地方出现了错误，老是提示org.xml.sax.SAXParseException: The content of element type “sqlMapConfig” must match “(properties?,settings?,resultObjectFactory?,ypeAlias*,typeHandler*,transactionManager?,sqlMap+)+”,

经过网上不断的搜索，终于找到了原因，原来ibatis配置文件的属性是有顺序的。

这个是我以前的代码：

<?xml version="1.0" encoding="UTF-8" ?>


<!DOCTYPE sqlMapConfig      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

<sqlMapConfig>
<settings
  cacheModelsEnabled="true"
  enhancementEnabled="true"
  lazyLoadingEnabled="true"
  maxRequests="32"
  maxSessions="10"
  maxTransactions="5"
  useStatementNamespaces="false"
  />
<properties resource="com/ibatis/utils/SqlMap.properties"/>
  <transactionManager type="JDBC" commitRequired="false">
    <dataSource type="SIMPLE">
      <property name="JDBC.Driver" value="${driver}"/>
      <property name="JDBC.ConnectionURL" value="${url}"/>
      <property name="JDBC.Username" value="${username}"/>
      <property name="JDBC.Password" value="${password}"/>
    </dataSource>
  </transactionManager>
  <sqlMap resource="com/ibatis/utils/User.xml"/>
</sqlMapConfig>

注意红色部分的顺序。

然而正确的顺序应该是

properties?,settings?,resultObjectFactory?ypeAlias*,typeHandler*,transactionManager?,sqlMap 

所以改成如下的顺序就OK了：

<?xml version="1.0" encoding="UTF-8" ?>


<!DOCTYPE sqlMapConfig      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">


<sqlMapConfig>


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


<settings
  cacheModelsEnabled="true"
  enhancementEnabled="true"
  lazyLoadingEnabled="true"
  maxRequests="32"
  maxSessions="10"
  maxTransactions="5"
  useStatementNamespaces="false"
  />
  <transactionManager type="JDBC" commitRequired="false">
    <dataSource type="SIMPLE">
      <property name="JDBC.Driver" value="${driver}"/>
      <property name="JDBC.ConnectionURL" value="${url}"/>
      <property name="JDBC.Username" value="${username}"/>
      <property name="JDBC.Password" value="${password}"/>
    </dataSource>
  </transactionManager>
  <sqlMap resource="com/ibatis/utils/User.xml"/>
</sqlMapConfig>
