spring+ibatis整合之配置文件

 首先配置datasource:这个配置和整合hibernate的配置一样,这里就不贴代码了,

直接贴配置sqlMapClient的bean配置:

 

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
        <property name="dataSource" ref="dataSource" />
         <property name="configLocations">
        <value>classpath*:/sqlmap-config/sqlmap-config.xml</value>
    </property>
    <property name="mappingLocations">
        <list>
            <value>classpath*:/sqlmap/**/*.xml</value>
        </list>
    </property>
    </bean>

其中configLocations是ibatis的配置文件路径,mappingLocations 可以当成是ibatis的映射文件

,其中这个文件的事例代码如下:

sqlmap-config

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig PUBLIC "-//iBatis.com//DTD SQL Map Config 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<!-- Always ensure to use the correct XML header as above! -->
<sqlMapConfig>
    <settings useStatementNamespaces="true" enhancementEnabled="true" maxTransactions="100" />

</sqlMapConfig>

映射文件的内容(列举其中的demo之一):

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="sqlmap-config">

    <select id="testSqlServer" parameterClass="java.util.HashMap" resultClass="java.util.HashMap" >
        SELECT name FROM systypes
    </select>
    <select id="testMySQL" parameterClass="java.util.HashMap" resultClass="java.util.HashMap" >
        select SYSDATE() from dual
    </select>
</sqlMap>

有了这些内容之后,简单配置一个baseDao:

 

<bean id="baseDao" class="com.lz.db.BaseDao"
    init-method="initialize">
    <property name="dataSource">
        <ref bean="dataSource" />
    </property>
    <property name="sqlMapClient">
        <ref bean="sqlMapClient" />
    </property>
</bean>

 

接下来是baseDao里面的代码:

 

 

public  class BaseDao extends SqlMapClientDaoSupport implements
        IBaseDao {



    public void initialize() throws Exception {

            SqlMapClient sqlMapClient = getSqlMapClientTemplate()
                    .getSqlMapClient();

    }

    public long getObjectTotal(String selectQuery, Object parameterObject) {
        prepareCountQuery(selectQuery);
        return (Long) getSqlMapClientTemplate().queryForObject(
                CountStatementUtil.getCountStatementId(selectQuery),
                parameterObject);
    }

    public long getObjectTotal(String selectQuery) {
        prepareCountQuery(selectQuery);
        return (Long) getSqlMapClientTemplate().queryForObject(
                CountStatementUtil.getCountStatementId(selectQuery));
    }

    protected void prepareCountQuery(String selectQuery) {
        String countQuery = CountStatementUtil.getCountStatementId(selectQuery);
        if (logger.isDebugEnabled()) {
            logger.debug("Convert " + selectQuery + " to " + countQuery);
        }
        SqlMapClient sqlMapClient = getSqlMapClientTemplate().getSqlMapClient();
        if (sqlMapClient instanceof ExtendedSqlMapClient) {
            SqlMapExecutorDelegate delegate = ((ExtendedSqlMapClient) sqlMapClient)
                    .getDelegate();
            try {
                delegate.getMappedStatement(countQuery);
            } catch (SqlMapException e) {
                delegate.addMappedStatement(CountStatementUtil
                        .createCountStatement(delegate
                                .getMappedStatement(selectQuery)));
            }

        }
    }
    Map param = new HashMap();
    private static final Logger log = LogManager.getLogger(BaseDao.class);
    public void addParameter(String key, Object value) {
        // TODO Auto-generated method stub
        this.param.put(key, value);
    }

    public void clearParameters() {

    }

    public int delete(String sqlId, Object param) {
        // TODO Auto-generated method stub

        } catch (SQLException e) {
            // TODO Auto-generated catch block
            log.error("删除数据错误:sqlId=" + sqlId + " param:" + param);
