Ibatis中SqlMapClientTemplate和SqlMapClient的区别

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);
	}
}
