jaxb2-maven-plugin 与 JUnit4 的集成

Question

我正在尝试执行一个简单的 JUnit 测试，以便 marshall/unmarshall 一些数据。

这里是'data'的定义：

@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;}
}

应用程序工作正常（我可以 marshall/unmarshall 这个对象 XML）

但是当我执行测试时，出现如下错误（测试中的代码与应用中的完全一样）：

我不明白为什么应用程序可以运行但测试不能运行。我想 Maven 中定义的插件范围有一些问题。这是我的 pom.xml :

<dependencies>      
    <dependency>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>jaxb2-maven-plugin</artifactId>

Answer 1

尝试添加到您的依赖项：

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

Answer 2

你不应该使用 jaxb2-maven-plugin 作为依赖项。

您可能需要添加

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