hibernate - 无法以一对一关系更新拥有方的属性

Question

我有一个User类，每个用户实例都有一个配置文件。该配置文件具有一个我想更新的avatarImage属性。我能够在运行时更新用户的字段，但不能更新该用户的个人资料的字段。我正在使用springsecurity获取currentUser，并且想更新他的avatarImage，但是在运行时得到了SQLException。

用户域类:

package com.clinton.kiitsocial

import groovy.transform.EqualsAndHashCode
import groovy.transform.ToString

@EqualsAndHashCode(includes='username')
@ToString(includes='username', includeNames=true, includePackage=false)
class User implements Serializable {
private static final long serialVersionUID = 1

transient springSecurityService

//don't touch this...for spring-security
String username
String password
boolean enabled = true
boolean accountExpired
boolean accountLocked
boolean passwordExpired

//starting custom domain...can touch this
Integer uniqueId
Date dateCreated
Date lastUpdated

static hasMany = [contents: Content]

static hasOne = [profile: Profile]


User(String username, String password) {
    this()
    this.username = username
    this.password = password
}

Set<Role> getAuthorities() {
    UserRole.findAllByUser(this)*.role
}

def beforeInsert() {
    encodePassword()
}

def beforeUpdate() {
    if (isDirty('password')) {
        encodePassword()
    }
}

protected void encodePassword() {
    password = springSecurityService?.passwordEncoder ? springSecurityService.encodePassword(password) : password
}

static transients = ['springSecurityService']

static constraints = {
    username blank: false, unique: true
    password blank: false, minSize: 5, validator: { pass, user ->
        pass != user.username
    }
    uniqueId blank: false, unique: true, range: 1000..2000000000

    profile unique: true, nullable: true
    contents nullable: true
}

static mapping = {
    password column: '`password`'
    profile fetch: 'join'
}

}

配置文件域类:

package com.clinton.kiitsocial

class Profile {
    String bio
    String contact
    String address
    GenderList gender
    String emailId
    Avatar avatarImage
    User user

    static hasMany = [socialNetworks: Social]

    static constraints = {
        bio nullable: true, maxSize: 50
        address nullable: true, maxSize: 50
        contact nullable: true, matches: "^\\+(?:[0-9] ?){6,14}[0-9]\$"
        socialNetworks nullable: true, unique: true
        gender nullable: true, blank: false
        emailId email: true, blank: true
        avatarImage nullable: true
    }
}

UserController:

@Secured(['ROLE_ADMIN', 'ROLE_USER'])
class UserController extends RestfulController {
    static responseFormats = ['json', 'xml']
    def userService
    UserController() {
        super(User)
    }

    def uploadAvatar() {
        MultipartFile avatar = request.getFile('avatar')
        avatar ? respond (userService.uploadingAvatar(avatar)): respond (500)
    }

    def showAvatar() {
    }
}

UserService:

package com.clinton.kiitsocial

    SpringSecurityService springSecurityService

        assert profile.user.username == user.username
        //assert !profile.avatarImage
        String message = ""
        if (!acceptedAvatarTypes.contains(file.contentType)) {
            //message = "Avatar must be one of: ${acceptedAvatarTypes} type"
            //respond 500
            return user
        }
        profile.avatarImage = new Avatar(avatar: file.bytes, avatarType: file.contentType)
        println("uploading: ${profile.avatarImage.avatarType}")
        if (!profile.save(failOnError: true, flush: true)) { //Error ocurs here
            message = "error occurred saving image"
            println("${profile.errors}")
            //respond user.errors
            return user
        }
         message = "Avatar (${profile.avatarImage.avatarType}, ${profile.avatarImage.avatar.size()} bytes) uploaded."
         println(message)
        println("finishing...")
        return user
    }

    /*def showAvatar(long  userId) {
        def avatarUser = User.get(userId)
        if (!avatarUser || !avatarUser.profile.avatarImage || !avatarUser.profile.avatarType) {
            //respond 404
            return
        }
        response.contentType = avatarUser.profile.avatarType
        response.contentLength = avatarUser.profile.avatarImage.size()
        OutputStream out = response.outputStream
        out.write(avatarUser.profile.avatarImage)
        out.close()
    }*/
}

我花了2天的时间来解决此问题。欢迎所有建议。感谢您的时间..

Answer 1

我想到了。我对其进行了集成测试，发现:休眠需要将内部域持久化并刷新，然后再将其附加到父域。喜欢自下而上的时尚。请参阅下面的答案。它是由瞬时域实例引起的。

Avatar uploadingAvatar(MultipartFile file) {
        User user = (User) springSecurityService.currentUser
        if (!user.profile) user.profile = new Profile(user: user).save(flush: true)
        if (!acceptedAvatarTypes.contains(file.contentType)) {
            responseCode = 500
        }

        Avatar avatar = user.profile.avatarImage ?: new Avatar()
        avatar.avatarName = file.originalFilename
        avatar.avatarBytes = file.bytes
        avatar.avatarType = file.contentType
        if (!avatar.validate() && !avatar.save(flush: true)){
            responseCode = 500
            return avatar
        }
        user.profile.avatarImage = avatar
        println("Avatar changed success")
        responseCode = 200
        return avatar
    }
