MyBatis調用存儲過程
1 存儲過程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 編寫SQL映射文件mapper.xml
<select parameterType="hashmap" statementType="CALLABLE">
<![CDATA[
{call pro_hello (#{p_user_name,mode=IN,jdbcType=VARCHAR},#{result,mode=OUT,jdbcType=VARCHAR})}
]]>
</select>
3 編寫JAVA代碼調用存儲過程
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 執行Java代碼，控製台輸出結果如下
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
