我很容易设法用简单属性（例如String类型）反序列化对象。但是当存在指向另一个类型的链接时，它不会自动解析，而是会出现异常。似乎链接未解析，但处理为简单的URI属性。
如何自动反序列化整个对象图？
从调试我知道，通过查询特定谓词的三元组来解析元素，因此在读取文件之前手动添加这些行时，可以将SubGeographicalRegion解组为JavaBean。
Class<SubGeographicalRegion> class1 = SubGeographicalRegion.class;
URI class1RdfType = RDFBeanInfo.get(class1).getRDFType();
PlainLiteral class1Literal = model.createPlainLiteral(class1.getName());
model.addStatement(class1RdfType, RDFBeanManager.BINDINGCLASS_PROPERTY, class1Literal);
但是，似乎有一个新对象被创建，即使只有一个和同一个SubGeographicalRegion的引用。
根据元素的ID实现hashCode()和equals()解决了多个实例的问题！

SubGeographicalRegion.java：

public class SubGeographicalRegion {

private String name;
private Collection<Substation> substations;

public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
// this works, but returns a HashSet<URI>
@RDF(inverseOf = "http://iec.ch/TC57/2010/CIM-schema-cim15#Substation.Region")
public Collection<Substation> getSubstations() {
return substations;

提示：方法SubGeographicalRegion.getSubstations()返回HashSet<URI>（尽管它被声明为Collection<Substation>）
以下是我启动引擎的方法：
org.ontoware.rdf2go.model.Model model = RDF2Go.getModelFactory().createModel();
model.open();
// try-catch omitted for readability
model.readFrom(getClass().getResourceAsStream(RDF_XML_INPUT_FILENAME), Syntax.RdfXml);
RDFBeanManager rdfBeanManager = new RDFBeanManager(model);
ClosableIterator<Substation> substationIterator = rdfBeanManager.getAll(Substation.class);
while (substationIterator.hasNext()) {
logger.info("substation.name: ", substationIterator.next().getName());
}
model.close();
