这些代码在 neo4j-manual-milestone.pdf（版本：1.8M05）中：
TraversalDescription t = new TraversalDescription();
t.setOrder( TraversalDescription.DEPTH_FIRST );
t.setUniqueness( TraversalDescription.NODE );
t.setMaxDepth( 10 );
t.setReturnFilter( TraversalDescription.ALL );
t.setRelationships( new Relationship( "singer", Relationship.OUT ) );
// END SNIPPET: traversalDesc
// START SNIPPET: traverse
URI traverserUri = new URI( startNode.toString() + "/traverse/node" );
WebResource resource = Client.create()
.resource( traverserUri );
String jsonTraverserPayload = t.toJson();
ClientResponse response = resource.accept( MediaType.APPLICATION_JSON )
.type( MediaType.APPLICATION_JSON )
.entity( jsonTraverserPayload )
.post( ClientResponse.class );
System.out.println( String.format(
"POST [%s] to [%s], status code [%d], returned data: "
+ System.getProperty( "line.separator" ) + "%s",
jsonTraverserPayload, traverserUri, response.getStatus(),
response.getEntity( String.class ) ) );
response.close();
当我使用它们时，会显示错误。
