Question

我在我的数据库中有一个任务列表我希望按状态和优先级获取任务，如果我没有传递status和priority，同样的查询应返回相应的结果。我写了一些东西，但这不是好方法状态和优先级是任务实体的变量
如果有任何想法，请帮助我对spring感到很新。请提前告诉你

服务：

public List<Task> getTasks(String status, String priority, String projectId) {
    if (!status.equals("undefined") && !priority.equals("undefined")
                && !projectId.equals("undefined")) {
            return taskRepository
                    .findByStatusAndPriorityAndProjectIdAndIsDelete(status,
                            priority, projectId, false);

        } else if (!(status.equals("undefined"))
                && (priority.equals("undefined"))
                && !(projectId.equals("undefined"))) {

            return taskRepository.findByStatusAndProjectIdAndIsDelete(status,
                    projectId, false);
        } else if (!(priority.equals("undefined"))
                && (status.equals("undefined"))
                && !(projectId.equals("undefined"))) {

            return taskRepository.findByPriorityAndProjectIdAndIsDelete(
                    priority, projectId, false);
        } else if ((priority.equals("undefined"))
                && (status.equals("undefined"))
                && !(projectId.equals("undefined"))) {
            return taskRepository.findByUsersAndProjectIdAndIsDelete(
                    authUtilService.getLoggedInUser(), projectId, false);
        } else {
            System.out.println("else called");
            return taskRepository.findByUsersAndIsDelete(
                    authUtilService.getLoggedInUser(), false);
        }

    }

存储库：

List<Task> findByUsersAndProjectIdAndIsDelete(User loggedInUser, String id,
            boolean b);

    List<Task> findByUsersAndIsDelete(User loggedInUser, boolean b);

    List<Task> findByTitleIgnoreCaseContainingAndIsDelete(String taskName,
            boolean b);


    List<Task> findByTenant(Tenant loggedInUsersTenant);

    List<Task> findByStatusAndPriorityAndProjectIdAndIsDelete(String status,
            String priority, String projectid, boolean b);



    List<Task> findByPriorityAndProjectIdAndIsDelete(String priority,
            String id, boolean b);

    List<Task> findByStatusAndProjectIdAndIsDelete(String status,
            String projectId, boolean b);

控制器：

@RequestMapping("/gettasks")
    @JsonView({ TaskJsonView.Summary.class })
    public List<Task> getTasks(@RequestParam("status")String status,@RequestParam("priority")String priority, @RequestParam("projectId") String projectId){

        return taskControllerService.getTasks(status,priority,projectId);

    }

任务实体：

@Entity
@Table(name = "tasks")
@EntityListeners(TaskEntityListener.class)
public class Task extends AbstractTenantEntity {

    private static final long serialVersionUID = 1L;

    @Column(name = "task_id", updatable = false)
    @JsonView({ TaskJsonView.class, ProjectJsonView.class,TaskJsonView.Summary.class })
    long taskId;

    @Column(name = "title")
    @JsonView({ TaskJsonView.class, ProjectJsonView.class,TaskJsonView.Summary.class })
    private String title;

    @Column(name = "status")
    @JsonView({ TaskJsonView.class, ProjectJsonView.class,TaskJsonView.Summary.class })
    private String status;

    @Column(name = "priority")
    @JsonView({ TaskJsonView.class, ProjectJsonView.class,TaskJsonView.Summary.class })
    private String priority;

    @Column(name = "description")
    @JsonView({ TaskJsonView.class, ProjectJsonView.class })
    String description;

    @Column(name = "start_date")
    @JsonView({ TaskJsonView.class, ProjectJsonView.class,TaskJsonView.Summary.class })
    Date startDate;

    @Column(name = "complete_date")
    @JsonView({ TaskJsonView.class, ProjectJsonView.class,TaskJsonView.Summary.class })
    Date completeDate;

    @Column(name = "deadline")
    @JsonView({ TaskJsonView.class, ProjectJsonView.class,TaskJsonView.Summary.class })
    Date deadline;

    @Column(name = "isdelete")
    @JsonView({ TaskJsonView.class, ProjectJsonView.class })
    boolean isDelete = false;

    @OneToMany(mappedBy = "task", fetch = FetchType.LAZY)
    @JsonView({ TaskJsonView.class })
    List<Comment> comments;

    @ManyToMany
    @JoinTable(name = "tasks_users", joinColumns = @JoinColumn(name = "task_id", referencedColumnName = "id"), inverseJoinColumns = @JoinColumn(name = "user_id", referencedColumnName = "id"))
    @JsonView({ TaskJsonView.class })
    List<User> users;

    @ManyToOne(fetch = FetchType.EAGER)
    @JsonView({ TaskJsonView.class,TaskJsonView.Summary.class })
    Project project;

    @OneToMany(mappedBy = "task", fetch = FetchType.EAGER)
    @JsonView({ TaskJsonView.class })
    List<SubTask> subtasks;

    @ManyToMany
    @JoinTable(name = "tasks_tags", joinColumns = @JoinColumn(name = "taskid"), inverseJoinColumns = @JoinColumn(name = "tagid"))
    @JsonView({ TaskJsonView.class })
    List<Tag> tags;

    public boolean isDelete() {
        return isDelete;
    }

实体在春天过滤
