myBatise调用存储过程

如何使用Mybaits调用数据库中的存储过程，下面以Oracle数据库的为例：

 

1．在数据库中创建以下的存储过程：

 

java代码：

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

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：

 

java代码：

<select id="proHello" statementType="CALLABLE">
<![CDATA[
    {call pro_hello (#{p_user_name,mode=IN,jdbcType=VARCHAR},#{result,mode=OUT,jdbcType=VARCHAR})}
]]>
</select>

<select id="proHello" 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

 

java代码：

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();
          }
       }
}

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：

 

java代码：

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

 

 

===============

有返回值时：

<!-- call procedure parameter -->
    <parameterMap id="parameterMap" type="java.util.HashMap">
     <parameter property="result" jdbcType="CURSOR" javaType="java.sql.ResultSet" mode="OUT" />
        <parameter property="TesterCode" jdbcType="VARCHAR" javaType="java.lang.String" mode="IN"/>
        <parameter property="Pwd" jdbcType="VARCHAR" javaType="java.lang.String" mode="IN"/>
    </parameterMap>
    
 <select id="getTesterByCodeAndPwd"  parameterMap="parameterMap" statementType="CALLABLE" resultMap="userResultMap">
        {? = call pkg_gettesterbycodeandpwd.proc_gettesterbycodeandpwd(?, ?)}
    </select>
</mapper>
