Question

你好我想显示一条消息和日期列表但不知道如何，我已经找到了一些代码（Model和Themeleaf），但我无法正确更改它：＆gt;我的代码：服务

@Autowired
private SpittleRepository spittleRepository;

private List<Spittle> spittles = new ArrayList<>(Arrays.asList(
        new Spittle("aaaa", new Date()),
        new Spittle("bbbbbb", new Date())
));

public List<Spittle> findSpittles() {
     List<Spittle> spittles = new ArrayList<>();
     spittleRepository.findAll().forEach(findedSpittles::add);
     return findedSpittles;
}}

控制器

@Autowired
SpittleService spittleService;

@RequestMapping(method = RequestMethod.GET)
public String findSpittles(Model model) {
    model.addAttribute("spittle", spittleService.findSpittles());
    return "spittles";
} }

实体

        @Id
        private final Long id;
        private final String message;
        private final Date time;
        private Double latitude;
        private Double longitude;



        public Spittle(String message, Date time, Double latitude, Double 
        longitude) {
            this.id = null;
            this.message = message;
            this.time = time;
            this.latitude = latitude;
            this.longitude = longitude;
        }

        public Spittle(String message, Date time) {
            this(message, time, null, null);
        }

        + geters
}}

Thymeleaf

<h2>Lista spiltów</h2>
       <table class="table table-striped">
           <tr>
               <th>Message</th>
               <th>Date</th>
           </tr>
           <tr th:each="spittle : ${spittle}">
               <td th:text="${spittle.getMessage()}"></td>
               <td th:text="${spittle.getTime()}"></td>
           </tr>
       </table>

存储库在扩展JpaRepository

中没有任何代码

Answer 1

尝试

         <tr th:each="spittle : ${spittles}">
               <td th:text="${spittle.message}"></td>
               <td th:text="${spittle.time}"></td>
           </tr>

您可能需要使用date.format来格式化日期。
