MyBatis-调用存储过程 -08

一、数据库表

USE mybatis;
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");

#创建存储过程(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)
DELIMITER $ #定义终结符
#CREATE PROCEDURE+存储过程名的方法创建存储过程，LANGUAGE选项指定了使用的语言，这里默认是使用SQL
CREATE PROCEDURE mybatis.ges_user_count(IN sex_id INT, OUT user_count INT)

#BEGIN END部分中，是存储过程的主体部分
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
$

#调用存储过程


二、实体类

package com.weixuan.mybatis.bean;

public class P_user {
private String id;
private String name;
private String sex;

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

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

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;
}

public P_user() {
super();
}

}


三、映射配置文件

<?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.weixuan.mybatis.bean.puser">
<select id="getCount" statementType="CALLABLE" parameterMap="getCountMap">
call mybatis.ges_user_count(?,?)
</select>
<parameterMap type="java.util.Map" id="getCountMap">
<parameter property="sexid" mode="IN" jdbcType="INTEGER" />
<parameter property="usercount" mode="OUT" jdbcType="INTEGER" />
</parameterMap>

</mapper>
