【问题标题】：The method createEntityGraph(Class<>) is undefined for the type EntityManagerEntityManager 类型的 createEntityGraph(Class<>) 方法未定义
【发布时间】：2014-12-23 07:58:51
【问题描述】：

以下代码行：

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

在eclipse中导致以下编译错误：

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

如何解决此错误？

以下是我的 pom.xml 的相关部分：

另外，在eclipse项目方面，JPA version设置为2.1。

【解决方案1】：

你的jee7项目没有正确设置你必须添加这个依赖：

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

【讨论】：

这并没有解决问题。我将依赖添加到pom.xml，然后在eclipse中做了maven download sources和maven update project，但是编译错误并没有消失。
