ibatis的引入——maven搭建spring mvc+ibatis项目(三)

1、spring中引入ibatis配置文件，上章已有相关配置，这里再补充重点的。

<!-- spring的ibatis 配制 -->
	<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
		<property name="configLocation">
			<value>classpath:config/ibatis.xml</value>
		</property>
		<property name="dataSource" ref="dataSource" />
	</bean>

2、config/ibatis.xml的内容：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE sqlMapConfig 
PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN" 
"http://www.ibatis.com/dtd/sql-map-config-2.dtd"> 
<sqlMapConfig> 
	<sqlMap resource="config/ibatis_dirCountry.xml" /> 
</sqlMapConfig>

3、config/ibatis_dirCountry.xml的内容：

<?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>
	<typeAlias type="com.bluedon.common.entity.TbDirCountryEntity" alias="dirCountry"/>
	<resultMap class="dirCountry" id="dirCountry">
		<result property="code" column="code" />
		<result property="name" column="name" />
	</resultMap>
	
	<select id="getAllDirCountry" resultMap="dirCountry">
    	select * from tb_dir_country
    </select>
	
	<select id="getDirCountryByParameter" parameterClass="java.util.Map" resultMap="dirCountry">
    	select * from tb_dir_country 
		<dynamic prepend="where"> 
	    	<isNotNull prepend="and" property="code">
	    		code = #code#
	    	</isNotNull>
	    	<isNotNull prepend="and" property="name">
	    		name like '%'||#name#||'%'
	    	</isNotNull>
	    </dynamic>
    </select>
</sqlMap>

4、实体类TbDirCountryEntity.java：

@SuppressWarnings("serial")
public class TbDirCountryEntity implements java.io.Serializable {
	/**code*/
	private java.lang.String code;
	/**name*/
	private java.lang.String name;
	
	/**
	 *方法: 取得java.lang.String
	 *@return: java.lang.String  code
	 */
	public java.lang.String getCode(){
		return this.code;
	}

	/**
	 *方法: 设置java.lang.String
	 *@param: java.lang.String  code
	 */
	public void setCode(java.lang.String code){
		this.code = code;
	}

	/**
	 *方法: 取得java.lang.String
	 *@return: java.lang.String  name
	 */
	public java.lang.String getName(){
		return this.name;
	}

	/**
	 *方法: 设置java.lang.String
	 *@param: java.lang.String  name
	 */
	public void setName(java.lang.String name){
		this.name = name;
	}
}

5、Action类：

@Controller
@RequestMapping("dirCountryAction")
public class DirCountryAction{
	@Resource
	private DirCountryService dirCountryService;
	
	@ResponseBody
	@RequestMapping(params="getAllList")
	public String getTbDirCountryList(HttpServletRequest req,HttpServletResponse resp){
		try {
			List<TbDirCountryEntity> list=this.dirCountryService.getDirCountryList();
			return JSONUtil.serialize(list);
		} catch (JSONException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return null;
	}	
	
	@ResponseBody
	@RequestMapping(params="getListByParameter")
	public String getListByParameter(HttpServletRequest req,HttpServletResponse resp){
		try {
			Map<String,Object> map=new HashMap<String,Object>();
			map.put("code", "2");
			map.put("name", "中");
			List<TbDirCountryEntity> list=this.dirCountryService.getDirCountryList(map);
			return JSONUtil.serialize(list);
		} catch (JSONException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return null;
	}
}	

6、Service接口和实现类：

public interface DirCountryService {
	public List<TbDirCountryEntity> getDirCountryList();
	
	public List<TbDirCountryEntity> getDirCountryList(Map<String,Object> map);
}

public class DirCountryServiceImpl implements DirCountryService{

	@Resource
	private DirCountryDao dirCountryDao;	
	
    @Override
	public List<TbDirCountryEntity> getDirCountryList(){
		return this.dirCountryDao.getDirCountryList();
	}

	@Override
	public List<TbDirCountryEntity> getDirCountryList(Map<String, Object> map) {
		// TODO Auto-generated method stub
		return this.dirCountryDao.getDirCountryListByParameter(map);
	}
}

7、Dao类：

@Repository("dirCountryDao")
public class DirCountryDao extends SqlMapClientDaoSupport  {
	public List<TbDirCountryEntity> getDirCountryList(){
	       return (List<TbDirCountryEntity>)this.getSqlMapClientTemplate().queryForList("getAllDirCountry");
	}
	
	public List<TbDirCountryEntity> getDirCountryListByParameter(Map<String, Object> map){
	       return this.getSqlMapClientTemplate().queryForList("getDirCountryByParameter", map);
	}
}
