小编给大家分享一下iBATIS SQLMap如何配置，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

iBATIS的SQLMap配置文件是XML形式，一般叫SqlMapConfig.xml，如下：

Xml代码

﹤?xml version="1.0" encoding="UTF-8"?﹥       ﹤!DOCTYPE sqlMapConfig  PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0/" "http://www.ibatis.com/dtd/sql-map-config-2.dtd"﹥        ﹤sqlMapConfig﹥        ﹤!--settings配置是可选的，用来控制sqlMapping的详细配置，主要是事务处理。参数具体含义请参考ibatis开发指南--﹥        ﹤settings cacheModelsEnabled="true" enhancementEnabled="true"            lazyLoadingEnabled="true" errorTracingEnabled="true" maxRequests="32"            maxSessions="10" maxTransactions="5" useStatementNamespaces="false" /﹥        ﹤!--使用SimpleDataSource配置数据源，DataSource的iBATIS实现：SimpleDataSource类，Jakarta DBCP（Commons），和可通过JNDI上下文查找的DataSource（即应用服务器中的DataSource）--﹥        ﹤transactionManager type="JDBC"﹥                ﹤dataSource type="SIMPLE"﹥                ﹤property name="JDBC.Driver"      value="com.mysql.jdbc.Driver" /﹥                ﹤property name="JDBC.ConnectionURL"      value="jdbc:mysql://127.0.0.1:3306/jpetstore?" /﹥                ﹤property name="JDBC.Username" value="root" /﹥                ﹤property name="JDBC.Password" value="" /﹥                ﹤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 ACCOUNT" /﹥                ﹤property name="Pool.PingEnabled" value="false" /﹥                ﹤property name="Pool.PingConnectionsOlderThan" value="1" /﹥                ﹤property name="Pool.PingConnectionsNotUsedFor" value="1" /﹥            ﹤/dataSource﹥        ﹤/transactionManager﹥        ﹤!--引入所有的SQL Map配置文件，这里的路径是classpath的相对路径，例如下面的配置说明引入Account.xml，位置在com/quqworld/test/ibatis包内--﹥        ﹤sqlMap resource="com/quqworld/test/ibatis/Account.xml" /﹥             ﹤/sqlMapConfig﹥

接下来是iBATIS SQLMap映射文件Account.xml：

Xml代码

﹤?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="Account"﹥        ﹤!--在SQL Map框架中，Result Map是极其重要的组件。在执行查询Mapped Statement时，resultMap负责将结果集的列值映射成Java Bean的属性值。--﹥        ﹤resultMap id="result"            class="org.springframework.samples.jpetstore.domain.Account"﹥            ﹤result property="username" column="userid" columnIndex="1" /﹥            ﹤result property="email" column="email" columnIndex="2" /﹥            ﹤result property="firstName" column="firstname" columnIndex="3" /﹥            ﹤result property="lastName" column="lastname" columnIndex="4" /﹥            ﹤result property="status" column="status" columnIndex="5" /﹥            ﹤result property="address1" column="addr1" columnIndex="6" /﹥            ﹤result property="address2" column="addr2" columnIndex="7" /﹥            ﹤result property="city" column="city" columnIndex="8" /﹥            ﹤result property="state" column="state" columnIndex="9" /﹥            ﹤result property="zip" column="zip" columnIndex="10" /﹥            ﹤result property="country" column="country" columnIndex="11" /﹥            ﹤result property="phone" column="phone" columnIndex="12" /﹥﹤/resultMap﹥            ﹤select id="getAllAccountByUserid" resultMap="result"﹥            select                 account.userid,                 account.email,                 account.firstname,                 account.lastname,                 account.status,                 account.addr1,                 account.addr2,                 account.city,                 account.state,                 account.zip,                 account.country,                 account.phone                 from account                 where account.userid=#value#         ﹤/select﹥    ﹤/sqlMap﹥

下面是iBATIS SQLMap的Java代码：

Java代码

try {             String resource = "com/quqworld/test/ibatis/SqlMapConfig.xml";             Reader reader = Resources.getResourceAsReader(resource);                 SqlMapClient sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader);             Object object =  sqlMap.queryForObject(                        "getAllAccountByUserid", "ACID",new Account());             System.out.println("select result: " +object);             } catch (Exception e) {             e.printStackTrace();         }
