SSM调用数据库存储过程

ServiceImpl中：

　Map<String,Object> map=new HashMap<String,Object>();
　map.put("bid", bc.getBookId());
　map.put("num", bc.getNumber());
　pcm.updateBookNumber(map);

Mapper.xml中

 <select id="updateBookNumber" parameterType="java.util.HashMap" statementType="CALLABLE" resultType="Integer">           
    {call updateWords( 
       #{bid,mode=IN,jdbcType=INTEGER},
       #{num,mode=IN,jdbcType=INTEGER},
       #{numbers,mode=OUT,jdbcType=INTEGER}
    )}    
 </select> 

Mapper.java中

public Integer updateBookNumber(Map<String,Object> map) throws Exception;

数据库中

BEGIN
    #Routine body goes here...
    DECLARE tempnumber long;
    SELECT number INTO tempnumber FROM 表名 WHERE `bookId`=bid;
    set tempnumber=tempnumber+num;
    UPDATE 表名 SET number=tempnumber WHERE bookId=bid;
END
