mybatis调用存储过程

直接贴代码吧注解式可以调用但是不能返回结果所有我就贴配置式的有知道注解怎么返回结果的请评论
数据库代码

#表
DROP TABLE IF EXISTS `p_user`;
CREATE TABLE `p_user` (`id` int(11) NOT NULL AUTO_INCREMENT,`name` varchar(10) DEFAULT NULL,`sex` char(2) DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;#模拟数据
INSERT INTO `p_user` VALUES ('1', 'A', '男');
INSERT INTO `p_user` VALUES ('2', 'B', '女');
INSERT INTO `p_user` VALUES ('3', 'C', '男');
#存储过程
CREATE PROCEDURE ges_user_count(OUT user_count int)
BEGIN  
IF sex_id=0 THEN
SELECT COUNT(*) FROM p_user WHERE p_user.sex='女' INTO user_count;
ELSE
SELECT COUNT(*) FROM p_user WHERE p_user.sex='男' INTO user_count;
END IF;
END

下面是mybatis配置的代码

    <!-- parameterMap.put("sexid", 0); parameterMap.put("usercount", -1); --><parameterMap type="java.util.Map" id="getUserCountMap"><parameter property="sexid" mode="IN" jdbcType="INTEGER" /><parameter property="usercount" mode="OUT" jdbcType="INTEGER" /></parameterMap><!-- 查询得到男性或女性的数量, 如果传入的是0就女性否则是男性 statementType="CALLABLE"存储过程类型 --><select id="getUserCount" parameterMap="getUserCountMap"statementType="CALLABLE">CALL ges_user_count(?,?)</select>

dao层代码

//接口
public interface UserMapper {public int getUserCount();
}
//实现类 我用spring的自动注入 也可以通过实例化来new SqlSessionFactory
package com.dw.user.dao;import java.util.HashMap;
import java.util.Map;import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
@Repository("userMapper")
public class UserMapperImpl implements UserMapper{//注入SqlSessionFactory@AutowiredSqlSessionFactory sessionFactory;public void setSessionFactory(SqlSessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}@Overridepublic int getUserCount() {SqlSession sqlSession = sessionFactory.openSession();Map<String, Integer> parameterMap = new HashMap<String, Integer>();//设置参数parameterMap.put("sexid", 1);parameterMap.put("usercount", -1);//Integer i = sqlSession.selectOne("com.dw.user.dao.UserMapper.getUserCount",parameterMap);Integer i = parameterMap.get("usercount");System.out.println(i);sqlSession.close();return i;}
}
