我有将JSON传递给RestController的问题.它似乎没有消耗它.

控制器:

@PostMapping(path = "Users/{UserId}/Transactions",
        consumes = MediaType.APPLICATION_JSON_VALUE,
        produces = MediaType.APPLICATION_JSON_VALUE)
public CompletableFuture<ResponseEntity<?>> startGameRound(@RequestBody TransactionRequest request,
                                                                            @RequestParam("PartnerUserSessionKey") String sessionId,
                                                                            @PathVariable("UserId") String playerUUID) throws ExecutionException, InterruptedException { // Logic }

TransactionRequest 对象模型:

public class TransactionRequest {
@JsonProperty("TransactionType")
private TransactionType transactionType;

@JsonProperty("TransactionId")
private String transactionId;

@JsonProperty("TransactionCreationDate")
private LocalDateTime transactionCreationDate;

@JsonProperty("Amount")
private Long amount;

@JsonProperty("Rake")
private BigDecimal rake;

@JsonProperty("CurrencyCode")
private String currencyCode;

@JsonProperty("EntityReferences")
private List<EntityReference> entityReferences;

@JsonProperty("Game")
private Game game;

public TransactionRequest() {
}
//getters & setters & hashEquals & toString 
}

这是试图发布到控制器的 …

我在将整数数组插入 Postgresql 表时遇到问题，我该如何解决？

String sql = "INSERT INTO draw_result (id, ball_numbers,  balls_with_mega_ball, draw_dates, mega_plier) VALUES(?, ?, ?, ?, ?)";
        Object[] params = {randomNumbers, ballNumbers, ballNumbersMegaBall, drawDates, megaPlier};
        jdbcTemplate.update(sql, params);

其中 ballNumbers 和 ballNumbersMegaBall 是 ArrayList。填充2位数字。

这是 PostgreSQL 表：

CREATE TABLE public.draw_result
(
id bigint NOT NULL,
draw_dates date, 
ball_numbers bigint[],
balls_with_mega_ball bigint[],
mega_plier bigint,
CONSTRAINT draw_result_pkey PRIMARY KEY (id)
)

这是来自 Springboot 的错误：

出现意外错误（类型=内部服务器错误，状态=500）。PreparedStatementCallback; 错误的 SQL 语法 [INSERT INTO draw_result (id, >ball_numbers, balls_with_mega_ball, draw_dates, mega_plier) VALUES(?, ?, ?, ?, >?)]; …

我需要正确地遵循SQL脚本语法.在postgres中,你不能真正将"alter sequence"与"select max(id)"链接起来.那么以PostgreSQL接受它的方式编写脚本的正确方法是什么？

这是脚本,所以你可以知道我需要什么:

 alter SEQUENCE notification_settings_seq START with (select max(id) from game_user)

我想将合适的对象传入验证方法，而不仅仅是 any()。

有没有办法做到这一点？

我不能只是采用和复制 Lambda 方法并将结果传递给验证。这不起作用，因为无法直接测试 Lambda。

我的单元测试显然还没有接近测试任何东西：

    @Test
public void testRunTrigger() {
    campaignTrigger.updateCampaignStatus();

    verify(jdbcTemplate).update(any(PreparedStatementCreator.class));
    assertEquals("UPDATE campaign SET state = 'FINISHED'  WHERE state IN ('PAUSED','CREATED','RUNNING') AND campaign_end < ? ", campaignTrigger.UPDATE_CAMPAIGN_SQL);
}

这是我正在测试的课程：

@Component
@Slf4j
public class CampaignTrigger {
final String UPDATE_CAMPAIGN_SQL = String.format("UPDATE campaign SET state = '%s' " +
                " WHERE state IN (%s) AND campaign_end < ? ", FINISHED,
        Stream.of(PAUSED, CREATED, RUNNING)
                .map(CampaignState::name)
                .collect(Collectors.joining("','", "'", "'")));

@Autowired
private JdbcTemplate jdbcTemplate;

@Scheduled(cron = "${lotto.triggers.campaign}")
@Timed
void updateCampaignStatus() { …
