get方法的所有测试都可以工作，这条线对它们很好：

.andExpect(content().json(ow.writeValueAsString(orders.get(0))))

下面是代码：testsetup

@Autowired
private MockMvc mockMvc;

@MockBean
private OrderService orderService;

private List<OrderDTO> orders;
private String ordersJson;
ObjectWriter ow;

@BeforeEach
void setUp() throws JsonProcessingException {
    orders = new LinkedList<>();
    for (int i = 1; i <= 3; i++) {
        orders.add(new OrderDTO.OrderDTOBuilder("test"+i, i*100)
                .build());
    }
    ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
    ordersJson = ow.writeValueAsString(orders);
}

失败的测试：

@Test
@DisplayName("POST /orders test - order saved with status 200")
@WithMockUser(roles = "PUBLISHER")
void saveNewOrder() throws Exception {
    Mockito.doReturn(orders.get(0)).when(orderService).saveOrder(any(),any(),any(),any());

    mockMvc.perform(
            MockMvcRequestBuilders.post("/orders")
                    .content(ow.writeValueAsString(orders.get(0)))
                    .contentType(MediaType.APPLICATION_JSON)
                    .accept(MediaType.APPLICATION_JSON))
            .andDo(MockMvcResultHandlers.print())
            .andExpect(content().json(ow.writeValueAsString(orders.get(0))))
            .andExpect(status().isOk())
            .andReturn();
}

测试控制器方法：

@PostMapping("")
public OrderDTO saveNewOrder(@RequestBody OrderDTO orderData,
                             @RequestBody List<Long> processes,
                             @RequestBody Long clientId,
                             @RequestBody Long deliveryId)
        {
    return orderService.saveOrder(orderData, processes, clientId, deliveryId);
}

下面是控制台消息：

你有两个选项，从你张贴。
选项1：通过更新到 required=false ```
@PostMapping("")
public OrderDTO saveNewOrder(@RequestBody OrderDTO orderData,
@RequestBody(required=false) List processes,
@RequestBody(required=false) Long clientId,
@RequestBody(required=false) Long deliveryId)
{
return orderService.saveOrder(orderData, processes, clientId, deliveryId);
}

选项2：在测试中添加所有必需的项目。这是一个片段，现在是真正的代码。

MockMvcRequestBuilders.post("/orders")
.content("send all the required data with orderData, processes, clientId and deliveryId"))
