Ibatis中SqlMapClientTemplate和SqlMapClient的区别

Answer 1

SqlMapClientTemplate是org.springframework.orm.ibatis下的

而SqlMapClient是ibatis的
SqlMapClientTemplate是SqlMapClient的封装类.
SqlMapClient中包含着session的管理.
SqlMapClientTemplate用于session的封装,以及异常的捕捉.
所以按照以上的推断来说.应该尽量使用SqlMapClientTemplate.
保证session以及Exception的正常以及统一.
下面是两种类型在spring中的集成配置及用法：、

SqlMapClientTemplate：

1、在spring中的配置

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation">
<value>classpath:/sqlmap-config.xml</value>
</property>
</bean>
<bean id="sqlMapClientTemplate" class="org.springframework.orm.ibatis.SqlMapClientTemplate">
<property name="sqlMapClient" ref="sqlMapClient"></property>
</bean>
<bean id="accountDAO" class="com.raycloud.test.dao.AccountDAO">
<property name="sqlMapClientTemplate" ref="sqlMapClientTemplate"></property>
</bean>
2、在dao中的实现

@Repository//使用该注解相当于声明了一个bean
public class AccountDAO {

SqlMapClientTemplate sqlMapClientTemplate;

public void setSqlMapClientTemplate(SqlMapClientTemplate sqlMapClientTemplate) {
this.sqlMapClientTemplate = sqlMapClientTemplate;
}

public Integer addAccount(Account account) throws SQLException{
return (Integer)this.sqlMapClientTemplate.insert("Account.insertAccount", account);
}
}

SqlMapClient：
1、在spring中的配置

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation">
<value>classpath:/sqlmap-config.xml</value>
</property>
</bean>
<bean id="accountDAO" class="com.raycloud.test.dao.AccountDAO">
<property name="sqlMapClient" ref="sqlMapClient"></property>
</bean>

2、在dao中的实现

@Repository//使用该注解相当于声明了一个bean
public class AccountDAO {

SqlMapClient sqlMapClient;

public void setSqlMapClient(SqlMapClient sqlMapClient) {
this.sqlMapClient = sqlMapClient;
}

public Integer addAccount(Account account) throws SQLException{
return (Integer)this.sqlMapClient.insert("Account.insertAccount", account);
}
}
