Question

我是ibatis的新手。我喜欢将SQLMapConfig文件和SQL映射资源拆分为2个文件。但是当我运行该项目时，它似乎显示错误。以下是我的2文件SQL Map。

SQLMapConfig.xml ：

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

  <transactionManager type="JDBC" >
    <dataSource type="DBCP">
      <property name="JDBC.Driver" value="com.mysql.jdbc.Driver"/>
      <property name="JDBC.ConnectionURL" value="jdbc:mysql://localhost:3306/sms_converter"/>
      <property name="JDBC.Username" value="root"/>
      <property name="JDBC.Password" value=""/>
    </dataSource>
  </transactionManager>
  <sqlMap resource="configuration/db/tbluser.xml" />
</sqlMapConfig>

这里是SQL Map资源 tbluser.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="MUser">
    <select id="getUserById" parameterClass = "com.me.bean.MUser" resultClass="com.me.bean.MUser">
        SELECT user_id AS sUserId FROM users where user.id = #sUserId#
    </select>
</sqlMap>

但是在我运行项目之后我遇到了这个错误：

Answer 1

无法找到资源配置/ db / tbluser.xml，因此请尝试添加前缀classpath：

<mapper resource="classpath:configuration/db/tbluster.xml">

Answer 2

尝试使用

<typeAlias alias="classMUser" type="com.me.bean.MUser" />

<resultMap id="userMap" class="classMUser">
    <result property="sUserId" column="sUserId" />
</resultMap>

<select id="getUserById" parameterClass = "com.me.bean.MUser" resultMap="userMap">
    SELECT user_id AS sUserId FROM users where user.id = #sUserId#
</select>

解析XPath'/ sqlMapConfig / sqlMap'时出现iBatis错误
