JMS 中的反射异常

Question

我正在 symfony 中开发一个简单的应用程序来学习 symfony.It 有术语，示例 entities.TermExamples 是一个实体是另一个实体，它是术语和 [ 之间的映射 table =32=] 很好，但是当我尝试使用 JMS 序列化程序进行序列化时，出现反射异常这些是我的实体

当我尝试添加带有例句的术语时，数据库中一切正常，但是当我尝试序列化该术语时，它显示错误

"message": "Property Madhuri\TermsBundle\Entity\TermExample::$exampleSentence does not exist",
                "class": "ReflectionException",
                "trace": [
                    {
                        "namespace": "",
                        "short_class": "",
                        "class": "",
                        "type": "",
                        "function": "",
                        "file": "/Users/madhuripalagummi/Documents/Dictionary/vendor/jms/metadata/src/Metadata/PropertyMetadata.php",

                        "args": []
                    },

我尝试清除教义缓存 metadata.But 仍然有效。当我在 TermExample 实体中添加字段 $exampleSentence 时，它 worked.But 为什么 TermExample 中应该有一个 $exampleSentence？谁能帮帮我？

Answer 1

JMS 将其序列化缓存单独存储到 Doctrine 中，因此我会尝试闪电式缓存（即删除缓存目录的内容，而不仅仅是执行 cache:clear 命令）并重试。听起来序列化程序保留了旧注释。
