概述
在开发中，有时候我们的接口需要去远程调用其他的接口，而在单元测试中，如果出现别人的接口没有开发完成或者远程服务不可用的情况，那么单元测试就不能进行下去，这时候就需要使用到下面的测试方法了，可以让我们指定远程调用方法返回一个我们自己指定符合规则的返回值，不用受限于远程接口的返回值，让单元测试能够进行下去
@MockBean
使用此注解注入的类，表明类中的所有方法都使用自定义返回的值，这样在测试的时候就不会真的去调用远程接口，而是返回一个我们预设的值
调用方法定义：TicketBuyOrderInfoVo getBuyOrderInfoVoByOrderId(@RequestParam("orderId") String orderId);
@MockBean
protected AirTicketBuyDataServiceFeignClient buyDataServiceFeignClient;
@Test
public void addComsumptions() {
String json =

TicketBuyOrderInfoVo orderInfoVo = GsonUtil.gson.fromJson(json, TicketBuyOrderInfoVo.class);
when(buyDataServiceFeignClient.getBuyOrderInfoVoByOrderId(anyString())).thenReturn(orderInfoVo);
}
.thenReturn(orderInfoVo)就是我们设置的调用指定方法之后的返回值，这里是返回一个TicketBuyOrderInfoVo对象
而即使不使用when().thenReturn()写法，直接调用，方法返回值也为Null
eg：
@Test
public void test() {
buyDataServiceFeignClient.getBuyOrderInfoVoByOrderId("fewfw");
}
@SpyBean
使用此注解注入的类，表明类中的某一个方法使用使用自定义返回的值，在测试时，如果使用到了多个方法，那么只是遵循@SpyBean写法的方法会返回我们自定义的值，在使用时在使用方法上和@MockBean类似，不过写法有所区别
调用方法定义：AutoOrder getAutoOrderByOrderId(String orderId, Date bizTime);
@SpyBean
protected IAutoTicketDao autoTicketDao;
@Test
public void addComsumptions_Out() {
String json1 = "{\"orderID\":\"190801084547167995\",\"sellerDeptID\":\"340559\",\"orderStatus\":8,\"outTicketTime\":\"2019-08-01 08:54:33\",\"payCompanyOrderID\":\"FX2019080143357941\",\"outTradeNo\":\"NT19080100004112\",\"airCode\":\"ZH\",\"seatClass\":\"E\",\"takeOffTime\":\"2019-08-08 21:35:00\",\"fromCity\":\"CKG\",\"toCity\":\"SZX\",\"inStockStaff\":\"SZX49802\",\"ticketOutInterface\":10,\"airPayAccount\":\"SZCYSD517\",\"inStockTime\":\"2019-08-01 08:54:33\",\"bigCustomerID\":\"\",\"buyerDeptName\":\"云南昆明盛世航空\",\"flightNO\":\"9428\",\"bigPNR\":\"PCYL5W\",\"orderPnr\":\"HM6XMK\"}";
AutoOrder autoOrder = GsonUtil.gson.fromJson(json1, AutoOrder.class);
doReturn(autoOrder).when(autoTicketDao).getAutoOrderByOrderId(anyString(), anyObject());
}
doReturn(autoOrder)就是我们设置的调用指定方法之后的返回值
遵循doReturn().when()写法的会返回我们自己定义的返参，如果直接调用的话还是会真正调用服务
而在使用时，方法的入参也有所改变
eg:
AutoOrder getAutoOrderByOrderId(String orderId, Date bizTime)，如果参数是String类型，测试时入参为anyString()，如果为对象类型，入参为anyObject()，布尔类型为anyBoolean()，Integer类型为anyInt()......，还有很对类型相对应的方法，这里不再赘述,，而如果方法的入参是一个固定的值，那么在测试时也要写为相同的值
