MyBatis调用存储过程

1 存储过程
create or replace procedure pro_hello(p_user_name in varchar2,p_result out varchar2) is
begin
  p_result := 'hello,' || p_user_name;
end;

2 编写SQL映射文件mapper.xml
<select id="proHello" parameterType="hashmap" statementType="CALLABLE">
<![CDATA[
    {call pro_hello (#{p_user_name,mode=IN,jdbcType=VARCHAR},#{result,mode=OUT,jdbcType=VARCHAR})}
]]>
</select>

3 编写JAVA代码调用存储过程
public class ProcedureTest {
         public static void main(String[] args) throws IOException {
            String resource = "mybatis.cfg.xml";
            Reader reader = Resources.getResourceAsReader(resource);
            SqlSessionFactory ssf = new SqlSessionFactoryBuilder().build(reader);
            SqlSession session = ssf.openSession();
       
            try {
                 Map<String, String> param = new HashMap<String, String>();
                 param.put("p_user_name", "zhangsan");
                 String returnValue = (String) session.selectOne("User.proHello", param);
                 System.out.println("message=" + param.get("p_user_name"));
                 System.out.println("result=" + param.get("result"));
                 System.out.println("returnValue=" + returnValue);
 
            }catch (Exception e) {
                e.printStackTrace();
            }finally {
              session.close();
            }
       }
}
 
4 执行Java代码，控制台输出结果如下
2012-03-07 20:36:32,406 DEBUG [java.sql.PreparedStatement] -==>  Executing: {call pro_hello(?,?)}
2012-03-07 20:36:32,406 DEBUG [java.sql.PreparedStatement] -==> Parameters: zhangsan(String)

message=zhangsan
