查看：180
本文介绍了NamedEntityGraph无法解析为类型的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

  NamedEntityGraph无法解析为类型
和
 NamedAttributeNode无法解析为类型

如何解决这些编译错误？



以下是显示编译错误的代码行：

  @Entity（name =someclass）
 @NamedEntityGraph（name =includeOther，attributeNodes = {@ NamedAttributeNode（other） $）
 @Table（name =sometable）
 public class SomeClass {
 //很多东西
} 
  pre> 
 
 
我认为问题是eclipse没有看到我配置了JPA 2.1。但是我试图安装和配置JPA 2.1。您可以在文件共享站点通过点击此链接阅读我的pom.xml的整个代码。我在eclipse项目方面设置了JPA 2.1，您可以通过点击此链接查看 。此外，我从Windows命令行在eclipse项目的根文件夹上运行 mvn依赖：tree ，并得到以下输出：

解决方案
 
 
 
 org.hibernate：hibernate-entitymanager：jar：4.2.1.Final：compile 
 
 
我不认为Hibernate 4.2.1支持JPA 2.1。您可能需要升级到Hibernate 4.3。
 
 
 
如果应用程序容器不提供，您可能还需要添加此依赖项：
 <依赖关系> 
< groupId> org.hibernate.javax.persistence< / groupId> 
< artifactId> hibernate-jpa-2.1-api< / artifactId> 
< version> 1.0.0.Final< / version> 
< / dependency> 
  
 
In an eclipse project that uses maven, jpa, and hibernate, I am getting the following two compilation errors:  
NamedEntityGraph cannot be resolved to a type  
and  
NamedAttributeNode cannot be resolved to a type  

How can I resolve these compilation errors?  



Here is the line of code that is showing the compilation errors:  
@Entity(name="someclass")  
@NamedEntityGraph(name="includeOther", attributeNodes={@NamedAttributeNode("other")})
@Table(name="sometable")
public class SomeClass {
    //lots of stuff
}

I think the problem is that eclipse is not seeing that I have JPA 2.1 configured.  But I have tried to install and configure JPA 2.1.  You can read the entire code of my pom.xml at a file sharing site by clicking on this link.  I set up JPA 2.1 in the eclipse project facets, which you can see by clicking on this link.  Also, I ran mvn dependency:tree on the root folder of the eclipse project from the windows command line, and I got the following output:

 解决方案 
From your dependency tree:

  
org.hibernate:hibernate-entitymanager:jar:4.2.1.Final:compile


I don't think Hibernate 4.2.1 supports JPA 2.1.  You may need to upgrade to Hibernate 4.3.



You may also want to add this dependency if your application container doesn't provide it:
<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.1-api</artifactId>
    <version>1.0.0.Final</version>
</dependency>
