jaxb2-maven插件與JUnit4的集成

我試圖執行一個簡單的JUnit測試，以便編組/解組一些數據。jaxb2-maven插件與JUnit4的集成

這裏是「數據」的定義：

@XmlRootElement(name = "data") 
@XmlAccessorType(XmlAccessType.FIELD) 
public class Data { 
public Data(){} 
@XmlAttribute(name = "name") 
private String name = "name"; 
public String getName(){return this.name;} 
public void setName(String name){this.name = name;} 
}

應用程序工作正常（我可以馬歇爾/解組此對象作爲XML）

但是，當我執行測試，我有以下錯誤（在測試的代碼是完全一樣的，因爲它是在應用程序）：

我不明白爲什麼應用程序的工作，但不是測試。我想有一些關於在maven中定義的插件範圍。這是我的pom.xml：

<dependencies>  
    <dependency> 
     <groupId>org.codehaus.mojo</groupId> 
     <artifactId>jaxb2-maven-plugin</artifactId> 
     <version>2.2</version> 
     <scope>test</scope> 
    </dependency> 
    <dependency> 
     <groupId>mockit</groupId> 
     <artifactId>jmockit</artifactId> 
     <version>0.999</version> 
     <scope>test</scope> 
    </dependency> 
    <dependency> 
     <groupId>junit</groupId> 
     <artifactId>junit</artifactId> 
     <version>4.11</version> 
     <scope>test</scope> 
    </dependency> 
</dependencies> 
<build> 
    <plugins> 
     <plugin> 
      <groupId>org.codehaus.mojo</groupId> 
      <artifactId>jaxb2-maven-plugin</artifactId> 
      <version>2.2</version> 
      <configuration>     
      </configuration> 
     </plugin> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-compiler-plugin</artifactId> 
      <version>3.3</version> 
      <configuration> 
       <source>1.8</source> 
       <target>1.8</target> 
      </configuration> 
     </plugin> 
    </plugins> 
</build>

你不應該使用jaxb2-maven-plugin的依賴。

而且你可能需要添加

 <dependency> 
      <groupId>com.sun.xml.bind</groupId> 
      <artifactId>jaxb-core</artifactId> 
      <version>2.2.11</version> 
     </dependency>

好吧。我刪除「JAXB2 - Maven的插件」依賴（只在「依賴」標籤），我添加了「JAXB核心」的依賴。它運作良好！即使如果我不明白爲什麼它的作品如此好:) –

嘗試添加到您的依賴關係：

<dependency> 
    <groupId>com.sun.istack</groupId> 
    <artifactId>istack-commons-runtime</artifactId> 
    <version>2.22</version> 
</dependency>
