我在我的项目中使用实体管理器。我可以成功地将我的实体和它们之间的关系读取/添加到数据库，但有一个问题。
我有两个节点 Employee 和 Document，它们之间的关系是 Employee HAS Document。
Emloyee 的 php 类：
<?php
namespace App\Models;
use GraphAware\Neo4j\OGM\Annotations as OGM;
use \GraphAware\Neo4j\OGM\Common\Collection;
/**
*
* @OGM\Node(label="Employee")
*/
class Employee implements \JsonSerializable {
public function __construct() {
$this->documents = new Collection();
$this->addresses = new Collection();
}
/**
* Id
* @var int
* @OGM\GraphId()
*/
protected $id;
/**
* name
* @var string
*
* @OGM\Property(type="string")
*/
protected $name;
/**
* lastname
* @var string
*
* @OGM\Property(type="string")
*/
protected $lastname;
/**
* personalidnumber
* @var string
*
* @OGM\Property(type="string")
*/
protected $personalidnumber;
/**
* @var Document[]|Collection
*
* @OGM\Relationship(type="HAS", direction="OUTGOING", collection=true, mappedBy="employees", targetEntity="Document")
*/
protected $documents;
/**
* @var Address[]|Collection
*
* @OGM\Relationship(type="HAS", direction="OUTGOING", collection=true, mappedBy="employees", targetEntity="Address")
*/
protected $addresses;
public function getaddresses() {
return $this->addresses;
}
public function getdocuments(){
return $this->documents;
}
public function getname(){
return $this->name;
}
public function setname($name){
$this->name = $name;
}
function getlastname() {
return $this->lastname;
}
public function setlastname($lastname){
$this->lastname = $lastname;
}
function getpersonalidnumber() {
return $this->lastname;
}
public function setpersonalidnumber($personalidnumber){
$this->personalidnumber = $personalidnumber;
}
public function jsonSerialize() {
return [
'id' => $this->id,
'name' => $this->name,
'lastName' => $this->lastname,
'personalidnumber' => $this->personalidnumber,
'addresses' =>$this->addresses->toArray(),
'documents' =>$this->documents->toArray()
];
}
}
文档的 php 类：
<?php
namespace App\Models;
use GraphAware\Neo4j\OGM\Annotations as OGM;
use GraphAware\Neo4j\OGM\Common\Collection;
/**
*
* @OGM\Node(label="Document")
*/
class Document implements \JsonSerializable{
public function __construct() {
$this->employees = new Collection();
$timezone = new \DateTimeZone('Europe/Ljubljana');
$t = microtime(true);
$micro = sprintf("%06d",($t - floor($t)) * 1000000);
$dt = new \DateTime( date('Y-m-d H:i:s.'.$micro, $t));
$dt->setTimezone($timezone);
$this->crdate = $dt->format('YmdHis.u');
$this->validfrom = $this->crdate;
}
/**

protected $id;
/**

protected $employees;
public function getemployees() {
return $this->employees;
}
public function getid() {
return $this->id;
}
public function getname() {
return $this->name;
}
public function setname($name) {
$this->name = $name;
}
public function getuniquename() {
return $this->uniquename;
}
public function setuniquename($uniquename) {
$this->uniquename = $uniquename;
}
public function getpath() {
return $this->path;
}
public function setpath($path) {
$this->path = $path;
}
public function getext() {
return $this->ext;
}
public function setext($ext) {
$this->ext = $ext;
}
public function getdocumentid() {
return $this->documentid;
}
public function setdocumentid($documentid) {
$this->documentid = $documentid;
}
public function getvalidfrom() {
return $this->validfrom;
}
public function setvalidfrom($validfrom) {
$this->validfrom = $validfrom;
}
public function getvalidto() {
return $this->validto;
}
public function setvalidto($validto) {
$this->validto = $validto;
}
public function getlanguage() {
return $this->language;
}
public function setlanguage($language) {
$this->language = $language;
}
public function getcrdate() {
return $this->crdate;
}
public function setcrdate($crdate) {
$this->crdate = $crdate;
}
public function gettype() {
return $this->type;
}
public function settype($type) {
$this->type = $type;
}
public function getdescription() {
return $this->description;
}
public function setdescription($description) {
$this->description = $description;
}
public function getfullname(){
return $this->path.$this->uniquename;
}
public function jsonSerialize() {
return [
'id' => $this->id,
'name' => $this->name,
'uniquename' => $this->uniquename,
'path' => $this->path,
'ext' => $this->ext,
'validfrom' => $this->validfrom,
'validto' => $this->validto,
'language' => $this->language,
'crdate' => $this->crdate,
'type' => $this->type,
'description' => $this->description,
'employees' => $this->employees->toArray()
];
}
}
然后我有两个 API 端点我使用 REST API 的 Slim 框架基本上我有两种返回数据的方法。
对于员工：
public function getAllEmployees(){
$this->logger->info(__CLASS__.':'.__FUNCTION__);
$employeesRepository = $this->dbentity->getRepository(Employee::class);
$employees = $employeesRepository->findAll();
return $employees;
}
文件：
public function getAllDocuments(){
$this->logger->info(__CLASS__.':'.__METHOD__);
$documentRepository = $this->dbentity->getRepository(Document::class);
$documents = $documentRepository->findAll();
return $documents;
}
所以我的问题是当我取消注释时
'employees' => $this->employees->toArray()
在文档类中
我得到一个运行时错误检测到递归
没有那条线一切正常。
有人可以帮我我错过了什么吗？
