java - How create a new FieldType in solr schema.xml -


i'm new solr, i'm developing application thesis, kind of search semantic engine ,i use springsource, (something siri or s-voice). use springsource , solr indexing documents,but have problem fieldtype. schema requires custom model (not class string parameter):

public class indexedobject{  private string id;  private arraylist<string> features;  private arraylist<semantic> semantic;  private string score;  private string time;  private int status;  @xmlelement(name="time") public string gettime() {     return time; }  @field public void settime(string time) {     this.time = time; }  @xmlelement(name="status") public int getstatus() {     return status; }  public void setstatus(int status) {     this.status = status; }  @xmlelement(name="score") public string getscore() {     return score; }  public void setscore(string score) {     this.score = score; }  @xmlelement(name="id", required=true) public string getid() {     return id; }  @field public void setid(string id) {     this.id = id; }  @xmlelementwrapper(name = "features") @xmlelement(name = "feature") public arraylist<string> getfeatures() {     return features; }  @field public void setfeatures(arraylist<string> features) {     this.features = features; }  @xmlelementwrapper(name = "semantics") @xmlelement(name = "semantic") public arraylist<semantic> getsemantic() {     return semantic; }  @field public void setsemantic(arraylist<semantic> semantic) {     this.semantic = semantic; }
