Question

因此，某个时间表属于某个用户，并且可以在多个日期或无时间内处于活动状态。我正在尝试使用通过方法名称创建的查询，其中找到其中userId =“x”并且dateActiveScheduleItem日期为=的时间表“x”。我的日程表回购如下，但我得到的错误是“没有为类型Schedule找到属性dateActiveScheduleItemDate！”

  @Repository
  public interface ScheduleDao extends JpaRepository<Schedule,Long> {
  Schedule findByUserIdAndDateActiveScheduleItemDate(Long 
 userId,java.util.Date date);
 }

Schedule（dateActiveScheduleItems列表是第二个表的链接）

@Entity
public class Schedule {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@ManyToOne
@JoinColumn(name = "user_id")
private User user;

@ManyToOne
@JoinColumn(name = "usergroup_id")
private UserGroup userGroup;

private String description;


private boolean master;//is this a schedule for all supervalus(true) or one supervalu(false)

@OneToMany(mappedBy = "schedule",cascade = CascadeType.PERSIST)
private List<DateActiveScheduleItem> dateActiveScheduleItems = new ArrayList<>();

@OneToMany(mappedBy = "schedule",cascade = CascadeType.PERSIST)
private List<MusicScheduleItem> musicScheduleItems = new ArrayList<>();

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public User getUser() {
    return user;
}

public void setUser(User user) {
    this.user = user;
}

public UserGroup getUserGroup() {
    return userGroup;
}

public void setUserGroup(UserGroup userGroup) {
    this.userGroup = userGroup;
}
public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}


public boolean isMaster() {
    return master;
}

public void setMaster(boolean master) {
    this.master = master;
}

public List<DateActiveScheduleItem> getDateActiveScheduleItems() {
    return dateActiveScheduleItems;
}

public void setDateActiveScheduleItems(List<DateActiveScheduleItem> dateActiveScheduleItems) {
    this.dateActiveScheduleItems = dateActiveScheduleItems;
}

public List<MusicScheduleItem> getMusicScheduleItems() {
    return musicScheduleItems;
}

public void setMusicScheduleItems(List<MusicScheduleItem> musicScheduleItems) {
    this.musicScheduleItems = musicScheduleItems;
}
}

DateActiveScheduleItem.java

 @Entity
 public class DateActiveScheduleItem {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@Basic
@Temporal(TemporalType.DATE)
private java.util.Date date;

@ManyToOne
@JoinColumn(name = "schedule_id")
private Schedule schedule;

public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}

public Date getDate() {
    return date;
}

public void setDate(Date date) {
    this.date = date;
}
}

Answer 1

方法名称应为

 findByUserIdAndDateActiveScheduleItems_Date

所以它就像这样

@Repository
  public interface ScheduleDao extends JpaRepository<Schedule,Long> {
  Schedule findByUserIdAndDateActiveScheduleItems_Date(Long 
 userId,java.util.Date date);
 }

因为你的变量名是dateActiveScheduleItems而且里面有你的日期。所以你应该使用_

使用两个表
