用JDBC读取postgresql json类型的数据

public static class RecBean{
		public String f1;
		public String f2;
		public String f3;
	}
	@Test
	public void testObjectAccess() throws Exception{
		TransJdbcTemplate lvTj = ContextHolder.getTransJdbcTemplate();
		Exception lvException= lvTj.doTransactionBatch(new TransCallback() {
			@Override
			public void onExecute(JdbcTemplate pvJt, NamedParameterJdbcTemplate pvNamedJt) throws Exception {
				List<Map<String,Object>> lvRet=pvJt.queryForList("select *,row_to_json(row(f96_line,f96_order,f96_station)) as rec from v96_qcdet_bylinejob where f96_date='24/Mar/2018'");
				PGobject lvObj =(PGobject) lvRet.get(0).get("rec");
				String lvVal=lvObj.getValue();
				RecBean lvRec=JsonUtils.readValue(lvVal, new TypeReference<RecBean>() {
				});
				Assert.assertNotNull(lvRec.f1);
			}		
		});
		if (lvException!=null)
			  throw lvException;
	}

还是用PGObject这个通用的类型来接收json的raw data(string类型), 然后通过JsonUtil转换为RecBean类型的对象 .
