/**
* Helper class that simplifies data access via the iBATIS
* {@link com.ibatis.sqlmap.client.SqlMapClient} API, converting checked
* SQLExceptions into unchecked DataAccessExceptions, following the
* {@code org.springframework.dao} exception hierarchy.
* Uses the same {@link org.springframework.jdbc.support.SQLExceptionTranslator}
* mechanism as {@link org.springframework.jdbc.core.JdbcTemplate}.
*
* <p>The main method of this class executes a callback that implements a
* data access action. Furthermore, this class provides numerous convenience
* methods that mirror {@link com.ibatis.sqlmap.client.SqlMapExecutor}'s
* execution methods.
*
* <p>It is generally recommended to use the convenience methods on this template
* for plain query/insert/update/delete operations. However, for more complex
* operations like batch updates, a custom SqlMapClientCallback must be implemented,
* usually as anonymous inner class. For example:
*
* <pre class="code">
* getSqlMapClientTemplate().execute(new SqlMapClientCallback() {
* public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {
* executor.startBatch();
* executor.update("insertSomething", "myParamValue");
* executor.update("insertSomethingElse", "myOtherParamValue");
* executor.executeBatch();
* return null;
* }
* });</pre>
*
* The template needs a SqlMapClient to work on, passed in via the "sqlMapClient"
* property. A Spring context typically uses a {@link SqlMapClientFactoryBean}
* to build the SqlMapClient. The template an additionally be configured with a
* DataSource for fetching Connections, although this is not necessary if a
* DataSource is specified for the SqlMapClient itself (typically through
* SqlMapClientFactoryBean's "dataSource" property).

<title>iBATIS SQL Maps</title>
<para>The iBATIS support in the Spring Framework much resembles the JDBC
support in that it supports the same template style programming, and as
with JDBC and other ORM technologies, the iBATIS support works with
Spring's exception hierarchy and lets you enjoy Spring's IoC
features.</para>
<para>Transaction management can be handled through Spring's standard
facilities. No special transaction strategies are necessary for iBATIS,
because no special transactional resource involved other than a JDBC
<interfacename>Connection</interfacename>. Hence, Spring's standard JDBC
<classname>DataSourceTransactionManager</classname> or
<classname>JtaTransactionManager</classname> are perfectly
sufficient.</para>
<note>
<para>Spring supports iBATIS 2.x. The iBATIS 1.x support classes are no
longer provided.<!--directed where? TR: REVISED, PLS REVIEW.--></para>
</note>
<section xml:id="orm-ibatis-setup">
<title>Setting up the <classname>SqlMapClient</classname></title>
<para>Using iBATIS SQL Maps involves creating SqlMap configuration files
containing statements and result maps. Spring takes care of loading
those using the <classname>SqlMapClientFactoryBean</classname>. For the
examples we will be using the following <classname>Account</classname>
class:</para>
<programlisting language="xml">public class Account {
private String name;
private String email;
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return this.email;
}
public void setEmail(String email) {
this.email = email;
}
}</programlisting>
<para>To map this <classname>Account</classname> class<!--*previous account class*:Identify the account class and the section you're talking about
TR: REVISED, PLS REVIEW. The Account class was part of the iBATIS 1.0 examples that were dropped a long time ago. No one has complained.
Makes you wonder if anyone actually reads thes docs :)--> with iBATIS 2.x we
need to create the following SQL map
<filename>Account.xml</filename>:</para>
<programlisting language="xml">&lt;sqlMap namespace="Account"&gt;
&lt;resultMap id="result" class="examples.Account"&gt;
&lt;result property="name" column="NAME" columnIndex="1"/&gt;
&lt;result property="email" column="EMAIL" columnIndex="2"/&gt;
&lt;/resultMap&gt;
&lt;select id="getAccountByEmail" resultMap="result"&gt;
select ACCOUNT.NAME, ACCOUNT.EMAIL
from ACCOUNT
where ACCOUNT.EMAIL = #value#
&lt;/select&gt;
&lt;insert id="insertAccount"&gt;
insert into ACCOUNT (NAME, EMAIL) values (#name#, #email#)
&lt;/insert&gt;
&lt;/sqlMap&gt;</programlisting>
<para>The configuration file for iBATIS 2 looks like this:</para>
<programlisting language="xml">&lt;sqlMapConfig&gt;
&lt;sqlMap resource="example/Account.xml"/&gt;
&lt;/sqlMapConfig&gt;</programlisting>
<para>Remember that iBATIS loads resources from the class path, so be
sure to add the<filename>Account.xml</filename> file to the class
path.</para>
<para>We can use the <classname>SqlMapClientFactoryBean</classname> in
the Spring container. Note that with iBATIS SQL Maps 2.x, the JDBC
<interfacename>DataSource</interfacename> is usually specified on the
<classname>SqlMapClientFactoryBean</classname>, which enables lazy
loading. This is the configuration needed for these bean
definitions:<!--Need intro to this example; what's its purpose? TR: REVISED, PLS REVIEW.--></para>
<programlisting language="xml">&lt;beans&gt;
&lt;bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"&gt;
&lt;property name="driverClassName" value="${jdbc.driverClassName}"/&gt;
&lt;property name="url" value="${jdbc.url}"/&gt;
&lt;property name="username" value="${jdbc.username}"/&gt;
&lt;property name="password" value="${jdbc.password}"/&gt;

<classname>SqlMapClientDaoSupport</classname></title>

<literal>SqlMapClient</literal> instance:</para>
<programlisting language="xml">&lt;beans&gt;
&lt;bean id="accountDao" class="example.SqlMapAccountDao"&gt;

<para>An <classname>SqlMapTemplate</classname> instance can also be
created manually, passing in the <literal>SqlMapClient</literal> as
constructor argument. The <literal>SqlMapClientDaoSupport</literal> base
class simply preinitializes a
<classname>SqlMapClientTemplate</classname> instance for us.</para>
<para>The <classname>SqlMapClientTemplate</classname> offers a generic
<literal>execute</literal> method, taking a custom
<literal>SqlMapClientCallback</literal> implementation as argument. This
can, for example, be used for batching:</para>
<programlisting language="java">public class SqlMapAccountDao extends SqlMapClientDaoSupport implements AccountDao {
public void insertAccount(Account account) throws DataAccessException {
getSqlMapClientTemplate().execute(new SqlMapClientCallback() {
public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {
executor.startBatch();
executor.update("insertAccount", account);
executor.update("insertAddress", account.getAddress());
executor.executeBatch();
}
});
}
}</programlisting>
<para>In general, any combination of operations offered by the native
<literal>SqlMapExecutor</literal> API can be used in such a callback.
Any thrown <literal>SQLException</literal> is converted automatically to
Spring's generic <classname>DataAccessException</classname>
hierarchy.</para>

<title>Implementing DAOs based on plain iBATIS API</title>
<para>DAOs can also be written against plain iBATIS API, without any
Spring dependencies, directly using an injected
<literal>SqlMapClient</literal>. The following example shows a
corresponding DAO implementation:</para>
<programlisting language="java">public class SqlMapAccountDao implements AccountDao {
private SqlMapClient sqlMapClient;
public void setSqlMapClient(SqlMapClient sqlMapClient) {
this.sqlMapClient = sqlMapClient;
}
public Account getAccount(String email) {
try {
return (Account) this.sqlMapClient.queryForObject("getAccountByEmail", email);
}
catch (SQLException ex) {
throw new MyDaoException(ex);
}
}
public void insertAccount(Account account) throws DataAccessException {
try {
this.sqlMapClient.update("insertAccount", account);
}
catch (SQLException ex) {
throw new MyDaoException(ex);
}
}
}</programlisting>
<para>In this scenario, you need to handle the
<literal>SQLException</literal> thrown by the iBATIS API in a custom
fashion, usually by wrapping it in your own application-specific DAO
exception. Wiring in the application context would still look like it
does in the example for the
<classname>SqlMapClientDaoSupport</classname><!--Clarify what wiring the app context looks like. What do you mean *before*? Looks like *what* specifically? TR: REVISED, PLS REVIEW.-->,
due to the fact that the plain iBATIS-based DAO still follows the
dependency injection pattern:</para>
<programlisting language="xml">&lt;beans&gt;
&lt;bean id="accountDao" class="example.SqlMapAccountDao"&gt;
&lt;property name="sqlMapClient" ref="sqlMapClient"/&gt;
&lt;/bean&gt;
&lt;/beans&gt;</programlisting>
