JSF抛出异常java.lang.StackOverflowError

Question

我有一个StackOverflowError我的环境Sping 3.2.0，JSF 2.1.9。

我正在使用带有转换器的OneMenuList，并且在我调试后返回转换器后，我在java.lang.StackOverflowError中遇到了此异常Phases.class。

Phases.class：

    try {
        handleBeforePhase(context, listeners, event);
        if (!shouldSkip(context)) {
            execute(context);
        }
    } catch (Throwable e) {
        queueException(context, e);
    }

尝试渲染JSF页面时，我开始收到以下错误。有人有什么想法吗？

转换器：

@Component
@FacesConverter(value = "programmeConverter")
public class ProgrammeConverter implements Converter {

@Autowired
@RmiClient
private IProgrammeService programmeService;

@Override
public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) {
    if (arg2 == null || arg2.isEmpty()) {
        return null;
    }

    String programme = arg2;
    Long value = Long.valueOf(programme);
    ProgrammeDto result = new ProgrammeDto();
    result = programmeService.findById(value);
    return result;
}

@Override
public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) {

    if (arg2 == null) {
        return "";
    }
    if(arg2 instanceof ProgrammeDto) {
        if (((ProgrammeDto) arg2).getIdProgramme() == null) {
            return "";
        }
    }

    ProgrammeDto programme = new ProgrammeDto();

    if(arg2 instanceof ProgrammeDto) {

        programme = (ProgrammeDto) arg2;
        String codeProgramme = programme.getIdProgramme().toString();
        return (codeProgramme != null) ? String.valueOf(codeProgramme) : null;
    } else throw new ConverterException("Something wrong!" + arg2.hashCode() + arg2.toString());

}
}

Controler：

@Component
@Scope("session")
public class ProgrammeController implements Serializable {

/**
 * 
 */
private static final long serialVersionUID = 2L;


private List<ProgrammeDto> listProgrammes = new ArrayList<ProgrammeDto>();

private ProgrammeDto selectedProgramme = new ProgrammeDto();
private ProgrammeDto programme = new ProgrammeDto();

@Autowired
@RmiClient
private IProgrammeService programmeService;

public String init(){
    actualize();
    return "/views/programme/listeProgramme?faces-redirect=true";
}

public void actualize(){
    selectedProgramme = new ProgrammeDto();
    listProgrammes = programmeService.findAll();
}

public String createDemnade(){
    prepareDtoBeforeSave();
    ProgrammeDto programmeCreatedId = programmeService.create(programme);
    FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("New Tiers Created : " + programmeCreatedId));
    return "/views/programme/newProgramme?faces-redirect=true";
}

protected void prepareDtoBeforeSave() {

}

public void getProgrammeByCode(){

}

/**
 * @return the listProgrammes
 */
public List<ProgrammeDto> getListProgrammes() {
    if (listProgrammes == null) {
        listProgrammes = new ArrayList<ProgrammeDto>();
    }
    return listProgrammes;
}

/**
 * @param listProgrammes the listProgrammes to set
 */
public void setListProgrammes(List<ProgrammeDto> listProgrammes) {
    this.listProgrammes = listProgrammes;
}

/**
 * @return the selectedProgramme
 */
public ProgrammeDto getSelectedProgramme() {
    ProgrammeDto programme = new ProgrammeDto();
    programme = selectedProgramme;
    return programme;
}

/**
 * @param selectedProgramme the selectedProgramme to set
 */
public void setSelectedProgramme(ProgrammeDto selectedProgramme) {
    this.selectedProgramme = selectedProgramme;
}
}
