为什么Hibernate会多次保存我的实体列表？

标签： java hibernate spring-boot jpa kotlin

我目前正在研究用Kotlin编写的Spring-boot应用程序。我正在编写一个API，该API允许登录的用户将地铁站或地铁线路添加到他的收藏夹中（并更快地获得有关其的信息）。
ApplicationUser类代表我的用户，其中包含用户名，密码，一组他最喜欢的地铁线路以及另一组他最喜欢的地铁站。

我写了一个控制器，允许已登录的用户将线路或桩号添加到他们的收藏夹中。我还编写了一个返回当前用户的函数。这是我的控制器的外观：

@RestController
@RequestMapping("/favorites")
class FavoriteController(private val applicationUserRepository: ApplicationUserRepository,
                         val lineService: LineService,
                         val stationService: StationService,
                         private var currentUser: ApplicationUser?) {

    private fun provideCurrentUser() : ApplicationUser? {
        if(this.currentUser == null) {
            val currentUsername: String = SecurityContextHolder.getContext().authentication.principal.toString()
            this.currentUser = this.applicationUserRepository.findByUsername(currentUsername)
        }
        return this.currentUser
    }


    @PostMapping
    fun addFavorite(@RequestParam(value = "type", required = true)type: FavoriteType?,
                    @RequestParam(value = "id", required = true)id: Long?) : ResponseEntity<String> {
        return if(provideCurrentUser() == null || type == null || id == null) {
            ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("You have to be logged and provide the type " +
                    "and the id of the desired entity in order to add it to your favorites list")
        } else {
            when(type) {
                FavoriteType.STATION -> {provideCurrentUser()?.addToFavorites(this.stationService.findById(id) as Station)
                    this.applicationUserRepository.save(provideCurrentUser() ?: throw Exception("User Not found"))}
                FavoriteType.LINE -> {provideCurrentUser()?.addToFavorites(this.lineService.findById(id) as Line)
                    this.applicationUserRepository.save(provideCurrentUser() ?: throw Exception("User Not found")) }
                FavoriteType.UNKNOWN -> return ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("Unknown entity type")
            }
            ResponseEntity.status(HttpStatus.CREATED).body("The $type with id $id has been successfully added to your favorites")
        }
    }

我认为它正在运行，但实际上在打了三个电话后引发了异常。第一次和第二次调用都可以正常工作，但是如果第三次调用此函数，则会由于数据库中的主键重复而引发异常。我使用JpaRepository函数来管理我的实体（保存）。
我认为这个问题可能来自交易的提早完成，但是我不知道如何检查它是否正确，或者如何解决它...

如果需要，这是我的ApplicationUser类的代码：

@Entity
class ApplicationUser(val username: String = "",
                      var password: String = "",
                      @ManyToMany(cascade= [CascadeType.ALL], fetch = FetchType.EAGER)
                      @JoinTable(name="user_favstation", joinColumns= [JoinColumn(name="user_id")], inverseJoinColumns=[JoinColumn(name="station_id")])
                      @CollectionId(
                              columns = [Column(name="COLLECTION_ID")],
                              type= Type(type="long"),
                              generator = "sequence"
                      )
                      var favoriteStations: MutableList<Station> = mutableListOf(),
                      @ManyToMany(cascade= [CascadeType.ALL] , fetch = FetchType.EAGER)
                      @JoinTable(name="user_favline", joinColumns= [JoinColumn(name="user_id")], inverseJoinColumns=[JoinColumn(name="line_id")])
                      @CollectionId(
                              columns = [Column(name="COLLECTION_ID")],
                              type= Type(type="long"),
                              generator = "sequence"
                      )
                      var favoriteLines: MutableList<Line> = mutableListOf())
    : BaseEntity() {

    fun addToFavorites(station: Station): Boolean {
        return this.favoriteStations.add(station)
    }

    fun addToFavorites(line: Line): Boolean {
        return this.favoriteLines.add(line)
    }

    fun deleteFavorite(station: Station): Boolean {
        return this.favoriteStations.remove(station)
    }

    fun deleteFavorite(line: Line): Boolean {
        return this.favoriteLines.remove(line)
    }
}

这是异常堆栈跟踪：

编辑：我通过在两个收藏夹列表上方添加@CollectionId注释来修改ApplicationUser类。由于此注释不适用于MutableSet，因此将其更改为MutableList。现在，我的控制器没有引发任何异常，但是我发现，每次尝试添加收藏夹休眠时，我都会再次添加每个收藏夹。在将仅4个电台添加到我的收藏夹之后，我的最爱电台表如下所示（而且我不知道为什么）：
favorite stations table

我希望有人能帮助我，谢谢您。
