缺少代碼屬性javax持久性

Question

在eclipse中運行junit 4測試時使用/不使用maven時，出現以下錯誤。

該項目運行良好。我不明白髮生了什麼事。我的POM包括以下依賴關係：

<!-- Java EE API 6 --> 
    <dependency> 
     <groupId>javax</groupId> 
     <artifactId>javaee-api</artifactId> 
     <version>${javaee-api.version}</version> 
     <scope>provided</scope> 
    </dependency> 
    <dependency> 
     <groupId>postgresql</groupId> 
     <artifactId>postgresql</artifactId> 
     <version>${postgresql.version}</version> 
     <scope>provided</scope> 
    </dependency> 
    <dependency> 
     <groupId>org.eclipse.persistence</groupId> 
     <artifactId>eclipselink</artifactId> 
     <version>${eclipselink.version}</version> 
     <scope>provided</scope> 
    </dependency> 

你對我的項目出了什麼問題有了解嗎？

謝謝。

Answer 1

該問題已通過'glassfish-embedded-web'依賴替換'javaee-api'依賴項解決。

單元測試需要功能實現，而不僅僅是api。

替換下面通過這種依賴項

<dependency> 
     <groupId>org.glassfish.main.extras</groupId> 
     <artifactId>glassfish-embedded-web</artifactId> 
     <version>${glassfish.version}</version> 
     <scope>provided</scope> 
    </dependency> 

問候在POM文件

<dependency> 
     <groupId>javax</groupId> 
     <artifactId>javaee-api</artifactId> 
     <version>${javaee-api.version}</version> 
     <scope>provided</scope> 
    </dependency> 

條目。
