使用JdbcTemplate调用输出参数为结果集(REF游标)的集合 博客分类： 常见问题 常见问题

//例子一：只有输出参数

	<!-- DB2 dataSource-->
	<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>

	
	
	<!-- jdbcTemplate -->
	 <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
		<property name="dataSource" ref="dataSource"/>
	</bean>

 @Test
    public void testRegisterCustomer() {
        List<Map<String, Object>> locationInfo = (List<Map<String, Object>>) jdbcTemplate.execute(
                "{call sp_rpt_satisfybyskill_new(?)}", new CallableStatementCallback() {
                    @Override
                    public Object doInCallableStatement(CallableStatement cs) throws SQLException, DataAccessException {
                        // 设置第一个输出参数的参数类型为游标类型
                        cs.registerOutParameter(1, OracleTypes.CURSOR);
                        // 执行存储过程
                        cs.execute();

                        // 获取第一个输出参数,从1开始
                        ResultSet rs = (ResultSet) cs.getObject(1);

                        List<Map<String, Object>> csList = new ArrayList<Map<String, Object>>();
                        // 转换每行的返回值到Map中
                        while (rs.next()) {
                            Map<String, Object> rowMap = new HashMap<String, Object>();
                            rowMap.put("zsnattachmentid", rs.getString("zsnattachmentid"));
                            rowMap.put("attachmentname", rs.getString("attachmentname"));
                            csList.add(rowMap);
                        }

                        rs.close();
                        return csList;
                    }

                });
        System.out.println(locationInfo);
    }

--下面是REF游标和存储过程
CREATE OR REPLACE PACKAGE Pack_Service AS
  TYPE t_RetDataSet IS REF CURSOR;
END Pack_Service;

CREATE OR REPLACE PROCEDURE Sp_Rpt_SatisfyBySkill_new
(
  rCursor               OUT Pack_Service.t_Retdataset  -- 返回结果集
)
AS
  exc_Param             EXCEPTION;
BEGIN

    OPEN rCurSor FOR
               select t.zsnattachmentid as "zsnattachmentid",t.attachmentname "attachmentname" from zsnattachment t where t.zsnattachmentid in(2000000236,2000000239);
  RETURN;
END;

 //例子二：输入输出参数都有

        List<Map<String, Object>> locationInfo = (List<Map<String, Object>>) jdbcTemplate.execute(
                "{call sp_rpt_satisfybyskill_new(?,?,?)}", new CallableStatementCallback() {
                    @Override
                    public Object doInCallableStatement(CallableStatement cs) throws SQLException, DataAccessException {
                        //设置第一个输入参数的值
                        cs.setLong(1, 2000000236);
                        //设置第二个输入参数的值
                        cs.setLong(2, 2000000256);
                        
                        // 设置第三个参数的参数类型为游标类型(registerOutParameter用来注册输出参数)
                        cs.registerOutParameter(3, OracleTypes.CURSOR);
                        // 执行存储过程
                        cs.execute();

                        // 获取第一个输出参数,3代表的是输出参数所在的位置
