但看看其他情况,我试图将这些依赖项放到 Maven 中:
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.21</version>
</dependency>
</dependencies>
我正在尝试直接从 Eclipse 运行,但我不断收到错误消息:java.lang.NoClassDefFoundError: javax/persistence/Persistence
我不明白,因为它应该由 javaee-api 依赖项提供。
问候, 爱德华多
更新
现在我尝试在我的 POM 中使用这些:
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.1.4.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.1.4.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate.java-persistence</groupId>
<artifactId>jpa-api</artifactId>
<version>2.0.Beta-20090815</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.21</version>
</dependency>
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-servlet-api</artifactId>
<version>7.0.26</version>
<scope>provided</scope>
</dependency>
</dependencies>
一旦 Tomcat 不会为我提供任何功能。但是我仍然遇到同样的错误,这可能与依赖范围有关吗?另外,我的进口是这样的:
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Persistence;
如何告诉我的容器使用 Hibernate 实现?
