方法createEntityGraph（類<>）是未定義的類型的EntityManager

Question

下面的行的代碼：

EntityGraph<Patient> graph = this.em.createEntityGraph(Patient.class); 

導致以下編譯錯誤在eclipse：

The method createEntityGraph(Class<SomeClass>) is undefined for the type EntityManager 

如何解決這個錯誤？

這裏是我的pom.xml的相關部分：

此外，JPA version在Eclipse項目方面設置爲2.1。

你jee7項目未正確設置你必須添加這種依賴性：

<dependency> 
     <groupId>javax</groupId> 
     <artifactId>javaee-api</artifactId> 
     <version>7.0</version> 
     <scope>provided</scope> 
    </dependency>
