读取文件内容并转换为对象

1.private static String readFileAsStringWithAbsolutePath(final String path) {try {final InputStream is = new FileInputStream(new File(path));return IOUtils.toString(is);} catch (IOException e) {LOG.error("Unknow IOException: " + e.getMessage(), e);return null;}}

2.final ExpectedResult expectedResult = JsonParsingUtil.fromJson(message, ExpectedResult.class);

3.public class ExpectedResult {private List<SalesProcessElem> serviceIds;private List<ServiceOrder> serviceOrders;private List<LedgerDetail> ledgerDetails;}

4.{    "service_ids":[{    "id":93887621,    "event_type":"create",    "service_status":"A"    }],    "ledger_details":[    ],     "service_orders":[    ]}

2中的message就是通过1中方法读取出来的，3是转换成的json对象，4是读取的文件内容即message
