私はJavaオブジェクトでアンマーチャしたいこのxmlファイルを持っています。私はMOXy JAXBライブラリを使用しています。

test.xml

    <?xml version="1.0" encoding="UTF-8"?>

<project >
    <type>org.netbeans.modules.ant.freeform</type>
            <compilation-unit>
                <package-root>src</package-root>
                <classpath mode="boot">${sunspot.bootclasspath}</classpath>
                <classpath mode="compile">${sunspot.classpath}</classpath>
                <built-to>build</built-to>
                <source-level>1.4</source-level>
            </compilation-unit>

</project>

ここに私のJavaクラスがあります: Project.java

package example;

import java.util.List;

import javax.xml.bind.annotation.*;


import org.eclipse.persistence.oxm.annotations.XmlPath;

@XmlRootElement
@XmlType(name = "project",propOrder = {"type", "compilation_unit"})
public class Project {
    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    private String type;


    @XmlPath("/compilation-unit")
    @XmlElement(name = "compilation-unit")
    private CompilationUnit compilation_unit;

    public CompilationUnit getPckg() {
        return compilation_unit;
    }

    public void setPckg(String pckg) {
        this.compilation_unit = compilation_unit;
    }


}

package example;

import org.eclipse.persistence.oxm.annotations.XmlPath;

import javax.xml.bind.annotation.XmlType;
import javax.xml.bind.annotation.XmlAccessType;

@XmlType(name = "compilation-unit", propOrder = {"package_root","built_to" ,"source_level" ,"classpath"})

public class CompilationUnit {
    public String getPackage_root() {
        return package_root;
    }

    public void setPackage_root(String package_root) {
        this.package_root = package_root;
    }

    public String getBuilt_to() {
        return built_to;
    }

    public void setBuilt_to(String built_to) {
        this.built_to = built_to;
    }

    public String getSource_level() {
        return source_level;
    }

    public void setSource_level(String source_level) {
        this.source_level = source_level;
    }

    public List<Classpath> getClasspath() {
        return classpath;
    }

    public void setClasspath(List<Classpath> classpath) {
        this.classpath = classpath;
    }

    private String package_root;
    private String built_to;
    private String source_level;
    private List<Classpath> classpath;

}

クラスパス:

package example;

import javax.xml.bind.annotation.XmlAttribute;

/**

 * User: leontiad
 * Date: Aug 5, 2010
 * Time: 11:33:52 AM

 */
public class Classpath {
    @XmlAttribute
    private String mode;
}

テスト用の Demo クラス:

package example;

import java.io.FileInputStream;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Project.class);

        FileInputStream xml = new FileInputStream("C:\\task.xml");
        Project project = (Project) jc.createUnmarshaller().unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(project, System.out);
    }
}

出力として得られるものは次のとおりです。

<?xml version="1.0" encoding="UTF-8"?>
<project>
   <type>org.netbeans.modules.ant.freeform</type>
</project>

xmlファイル全体が印刷されず、その一部のみが印刷される理由を理解するのに役立つ人はいますか?

JAXB はあまり使っていませんが、compilation_unit フィールドには @XmlPath("/compilation-unit") は必要ないと思います。xml を逆シリアル化すると、パスの注釈が xml と一致しないと思います。

いくつかの注釈が欠けていました。以下は修正されたクラスです。
