1、準備資料：

create table p_user(  
    id int primary key auto_increment,  
    name varchar(10),
    sex char(2)
); 

insert into p_user(name,sex) values('A',"男");  
insert into p_user(name,sex) values('B',"女");  
insert into p_user(name,sex) values('C',"男");  

#建立儲存過程(查詢得到男性或女性的數量, 如果傳入的是0就女性否則是男性)
DELIMITER $
CREATE
 
 PROCEDURE mybatis.ges_user_count(IN sex_id INT, OUT user_count INT)
BEGIN  
IF sex_id=0 THEN
SELECT COUNT(*) FROM mybatis.p_user WHERE p_user.sex='女' INTO user_count;
ELSE
SELECT COUNT(*) FROM mybatis.p_user WHERE p_user.sex='男' INTO user_count;
END IF;
END 
$

#呼叫儲存過程
DELIMITER ;
SET @user_count = 0
 
;
CALL mybatis.ges_user_count(1, @user_count);
SELECT @user_count;

2、準備實體類：

package com.atguigu.day03_mybaits.bean;

public class PUser {

    private String id;
    private String name;
    private String sex;

    public PUser(String id, String name, String sex) {
        super();
        this
 
.id = id;
        this.name = name;
        this.sex = sex;
    }

    public PUser() {
        super();
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    @Override
    public String toString() {
        return "PUser [id=" + id + ", name=" + name + ", sex=" + sex + "]";
    }

}

3、對映檔案：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.atguigu.day03_mybaits.test8.userMapper">
    <!-- 
        查詢得到男性或女性的數量, 如果傳入的是0就女性否則是男性
     -->
    <select id="getUserCount" parameterMap="getUserCountMap" statementType="CALLABLE">
        CALL mybatis.ges_user_count(?,?)
    </select>

    <!--
        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>
</mapper>

測試程式碼：

package com.atguigu.day03_mybaits.test8;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;

import com.atguigu.day03_mybaits.bean.ConditionUser;
import com.atguigu.day03_mybaits.bean.User;
import com.atguigu.day03_mybaits.util.MybatisUtils;
/**
 * 測試呼叫儲存過程
 * @author xfzhang
 *
 */
public class Test8 {

    public static void main(String[] args) {
        SqlSessionFactory factory = MybatisUtils.getFactory();
        SqlSession session = factory.openSession();

        String statement = "com.atguigu.day03_mybaits.test8.userMapper.getUserCount";

        Map<String, Integer> parameterMap = new HashMap<String, Integer>();
        parameterMap.put("sexid", 1);
        parameterMap.put("usercount", -1);


        session.selectOne(statement, parameterMap);

        Integer result = parameterMap.get("usercount");
        System.out.println(result);

        session.close();
    }
}
