BookMapper.java 映射接口文件
public int delbook(int id);

BookMapper.xml 映射配置文件
<parameterMap id="pm" type="map">
<parameter property="id" javaType="int" mode="IN"/>
</parameterMap>

<update id="delbook" statementType="CALLABLE" parameterMap="pm">
{call delbook(?)}
</update>

程序调用
int i = bdao.delbook(3);

-- 声明一个插入数据的存储过程--------------------------------------------
delimiter $$
create procedure addbook(name varchar(20),price decimal(8,2))
begin
insert into book(book_name,book_price) values(name,price);
end$$
delimiter ;

-- 调用一下
call addbook(‘《java开发》‘,80);

BookMapper.java 映射接口
public int addBook(Map<String,Object> map);

BookMapper.xml 映射文件
注册映射文件的参数顺序
<parameterMap id="am" type="map">
<parameter property="name" javaType="String" mode="IN"/>
<parameter property="price" javaType="double" mode="IN"/>
</parameterMap>
<update id="addBook" statementType="CALLABLE" parameterMap="am">
{call addbook(?,?)}
</update>

程序调用方法
Map<String,Object> m = new HashMap<String,Object>();
m.put("name","《项目开发》");
m.put("price",28d);
int i = bdao.addBook(m);
System.out.println(i);

-- 声明定义存储过程--------------------------------------------
delimiter $$
create procedure showbook()
begin
select * from book;
end$$
delimiter ;

-- 调用存储
call showbook;
call showbook();

BookMapper.java
public List<Book> showbook();

BookMapper.xml
<resultMap id="mp" type="book">
<id column="book_id" property="id"/>
<result column="book_name" property="name"/>
<result column="book_price" property="price"/>
</resultMap>

<select id="showbook" statementType="CALLABLE" resultMap="mp">
{call showbook()}
</select>

程序代码
List<Book> bks = bdao.showbook();
System.out.println(bks.size());
for(Book b : bks){
System.out.println(b.getName());
}

-- 声明定义存储过程
delimiter $$
create procedure bookcc(out r int)
begin
select count(*) into r from book;
end$$
delimiter ;


call bookcc(@r);
select @r;

BookMapper.java
public void bookcc(Map<String,Object> map);

BookMapper.xml 文件
<select id="bookcc" statementType="CALLABLE">
{call bookcc(#{r,mode=OUT,jdbcType=INTEGER})}
</select>

程序代码调用
Map<String,Object> m = new HashMap<String,Object>();
bdao.bookcc(m);
System.out.println(m.get("r"));

别一种方式
BookMapper.java 映射接口
public void bookcc(Map<String,Object> map);

BookMapper.xml 映射配置文件
<parameterMap id="cm" type="map">
<parameter property="r" jdbcType="INTEGER" mode="OUT"/>
</parameterMap>

<select id="bookcc" statementType="CALLABLE" parameterMap="cm">
{call bookcc(?)}
</select>
程序代码为
Map<String,Object> m = new HashMap<String,Object>();
bdao.bookcc(m);
System.out.println(m.get("r"));
