在我的网页上显示正确的信息。

Question

我的问题是如何使用NodeEntity类中的getLabel，getX，getY，并在我的网页上显示查询结果，而不是获取“ org.neo4j.ogm.response.model”。 / strong>我不知道是否应在控制器或存储库类中使用这些get方法，以便在网页表上显示节点信息。

@NodeEntity
public class Room {

    @Id @GeneratedValue
    private Long id;

    @Property(name = "label")
    private String label;

    @Property(name = "shape")
    private String shape;

    @Property(name = "colour")
    private String colour;

    @Property(name = "x")
    private String x;

    @Property(name = "y")
    private String y;


    @Relationship(type = "To")
    private Collection<Room> roomTo = new ArrayList<>();

    @Relationship(type = "Up")
    private Collection<Room> roomUp = new ArrayList<>();

    @Relationship(type = "Down")
    private Collection<Room> roomDown = new ArrayList<>();

    @JsonIgnoreProperties("room")
    @Relationship(type = "To", direction = Relationship.INCOMING)
    Collection<RelEnt> relEnts;

    public Room(){

    }
    public String getLabel(){
        return label;
    }

    public String getShape(){
        return shape;
    }

    public String getColour(){
        return colour;
    }

    public String getX() {
        return x;
    }

    public String getY() {
        return y;
    }
}

存储库：

public interface NavigatorRepository extends Neo4jRepository<Room, String>{

    @Query("match (r1: Room {label: {from}}), (r2: Room {label: {to}}), p = shortestPath((r1)-[*]-(r2)) unwind nodes(p) as room return room")
    Iterable<Map<String, Object>> getShortestRoute(@Param("from") String from, @Param("to") String to);
}

服务：

@Service
public class NavigatorService {

    @Autowired
    NavigatorRepository navigatorRepository;

    public Iterable<Map<String, Object>> shortestRoute(String from, String to){
        return navigatorRepository.getShortestRoute(from, to);
    }
}

控制器：

@Controller
public class AunController {

    @RequestMapping(value = "/AUN") //this will allow you to access web page with just http://localhost:8081/
    public String homePage(){
        return "AUN-Web"; //uses the static html file created for the web page
    }

    @Autowired
    NavigatorService navigatorService;

    @GetMapping(value = "/navigate")
    public String navigate(@RequestParam(name="from") String from, @RequestParam(name="to") String to, Model model) {
       Iterable<Map<String, Object>> route = navigatorService.shortestRoute(from, to);

        model.addAttribute("from", from)
                .addAttribute("route", route)
                .addAttribute("to", to);
        return "AUN-Results";
    }

    @GetMapping(value = "/")
    public String error(){
        return "Error/404";
    }
}

HTML：

 <form action="/navigate" method="">
        <strong><label for="ifrom">Current Location:</label></strong> <br>

        <input id="ifrom" type="text" placeholder="MB" name="from"><br>

        <strong><label for="ito">Destination:</label></strong> <br>

        <input id="ito" type="text" placeholder="MB" name="to"><br>

        <p style="line-height: 30px; width: 300px;"></p>

        <button type="button" class="btn btn-success" onclick="result">Search</button>

        <p style="line-height: 30px; width: 300px;"></p>
    </form>
</div>

<div align="center" class="container-fluid">

    <h5>Going from <span th:text="${from}">MB220</span> to <span th:text="${to}">MB265</span></h5>
        <table class="table">
            <tr>
                <th>Label</th>
                <th>X</th>
                <th>Y</th>
            </tr>
            <tr th:each="route : ${route}">
                <td th:text="${route}">Mb220</td>

            </tr>
        </table>
</div>

尝试将您的foreach变量名称更改为“ routpoint”之类的名称，以使其与完整路由有所不同。
