首先感谢网络上以为朋友。其实我不认识。看到他的博客才做出来。

存储过程都是一样的,只是根据自己的喜好,可以用MAP或者JAVABEAN传递参数。
class="sql">-- -------------------------------------------------------------------------------- -- Routine DDL -- Note: comments before and after the routine body will not be stored by the server -- -------------------------------------------------------------------------------- DELIMITER $$ CREATE DEFINER=`root`@`localhost` PROCEDURE `selectCount`( IN pcsId int, IN drId int, IN partnerId int, IN customerId int, OUT pcsCount int, OUT drCount int ) BEGIN select count(md.id) into @pcsC from mdm_device md left join mdm_device_security mds on mds.device_id = md.id where mds.device_rooted = pcsId and md.partner_id = partnerId and md.customer_id = customerId; set pcsCount = @pcsC; select count(md.id) into @drC from mdm_device md where md.managed_status = drId and DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(md.un_manage_date) and md.partner_id = partnerId and md.customer_id = customerId; set drCount = @drC; END

1.java调用传入MAP。获取通过MAP获取。
1.1 mapper文件写法
<parameterMap type="map" id="homeVO"> <parameter property="pcsId" jdbcType="INTEGER" mode="IN"/> <parameter property="drId" jdbcType="INTEGER" mode="IN"/> <parameter property="partnerId" jdbcType="INTEGER" mode="IN"/> <parameter property="customerId" jdbcType="INTEGER" mode="IN"/> <parameter property="pcsCount" jdbcType="INTEGER" mode="OUT"/> <parameter property="drCount" jdbcType="INTEGER" mode="OUT"/> </parameterMap> <select id="selectForHome" parameterMap="homeVO" statementType="CALLABLE"> {call selectCount( ?,?,?,?,?,? )} </select>
?1.2 java调用写法
@Override public StringselectHomeCount(HomeVO home) throws Exception { Map<String, Object> map = new HashMap<String, Object>(); map.put("pscId", 0); map.put("drId", 1); map.put("partnerId", 25); map.put("customerId", 50); map.put("isolation", 1); selectOne("Mapper.selectForHome", map); System.out.println(map.get("pcsCount")); return map.get("drCount"); }

2.java调用传入javaBean。返回值通过javaBean属性获取
2.1 通过javabean传递参数 ?mapper写法
<parameterMap type="com.polysaas.mdm.device.entity.HomeVO" id="home"> <parameter property="pcsId" jdbcType="INTEGER" mode="IN"/> <parameter property="drId" jdbcType="INTEGER" mode="IN"/> <parameter property="partnerId" jdbcType="INTEGER" mode="IN"/> <parameter property="customerId" jdbcType="INTEGER" mode="IN"/> <parameter property="pcsCount" jdbcType="INTEGER" mode="OUT"/> <parameter property="drCount" jdbcType="INTEGER" mode="OUT"/> </parameterMap>
?javaBean可以通过两种来进行映射
<resultMap type="com.polysaas.mdm.device.entity.HomeVO" id="home"> <result column="partnerId" property="partnerId" jdbcType="INTEGER"/> <result column="customerId" property="customerId" jdbcType="INTEGER" /> <result column="pcsId" property="pcsId" jdbcType="INTEGER" /> <result column="drId" property="drId" jdbcType="INTEGER" /> <result column="pcsCount" property="pcsCount" jdbcType="INTEGER" /> <result column="drCount" property="drCount" jdbcType="INTEGER" /> </resultMap> <select id="selectForHome2" parameterType="com.polysaas.mdm.device.entity.HomeVO" statementType="CALLABLE"> {call selectCount( #{pcsId,jdbcType=INTEGER, mode=IN}, #{drId, jdbcType=INTEGER,mode=IN}, #{partnerId, jdbcType=INTEGER,mode=IN}, #{customerId, jdbcType=INTEGER,mode=IN}, #{pcsCount, jdbcType=INTEGER,mode=OUT}, #{drCount, jdbcType=INTEGER,mode=OUT} )} </select>
?2.2 通过javabean传递参数 ?java调用写法
@Override public HomeVO selectHomeCount(HomeVO home) throws Exception { HomeVO vo = new HomeVO(); vo.setPcsId(0); vo.setDrId(0); vo.setPartnerId(25); vo.setCustomerId(50); vo.setPcsCount(0); vo.setDrCount(0); selectOne("com.polysaas.mdm.device.mapper.MdmDeviceMapper.selectForHome2", vo); return vo; }

遇到异常很多。。记得的写下
1.通过javaBean的时候,#{pcsId, mode=IN, javaType=INTEGER},javaType这个属性是必须的。
2.使用javaBean传递。输出参数不需要初始值。个人喜好并建议使用javaBean,因为定义更清晰,封装性。
3.map可以用占位符问号,javaBean不可以。 ?会有异常?No value specified for parameter 1
