                </h:panelGrid>
                    <h:commandButton value="保存" action="#{readeredit.edit()}" />
            </h:form>
        </f:view>

    </h:body>

Generating jsf page needs a method returning entity.So i write this method, code is here:

public TbReader getReader() {
    String id = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("tid");
    if (id != null && !id.isEmpty()) {
        this.typeid = id;
    }

reader = uecon.findTbReader(Integer.parseInt(typeid.trim()));
return reader;

}

and the whole codes of my jsf managed bean is here:

@Named(value = "readeredit")
@SessionScoped
public class readeredit implements Serializable {

    @Resource
    UserTransaction utx;
    @PersistenceUnit(unitName = "BMsPU")
    private EntityManagerFactory emf;
    TbReaderJpaController uecon;
    private String typeid;
    private TbReader reader;

    public TbReader setReader(TbReader reader) {
        this.reader = reader;
        return reader;
    }

    public String getTypeid() {
        return typeid;
    }

    public void setTypeid(String typeid) {
        this.typeid = typeid;
    }

    @PostConstruct
    public void init() {
        uecon = new TbReaderJpaController(utx, emf);
        this.setTypeid(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("tid"));
    }

    public TbReader getReader() {
        String id = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("tid");
        if (id != null && !id.isEmpty()) {
            this.typeid = id;
        }
        reader = uecon.findTbReader(Integer.parseInt(typeid.trim()));
        return reader;
    }
    public String edit(TbReader rd) throws Exception {
        String id = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("tid");
        if (id != null && !id.isEmpty()) {
            this.typeid = id;
        }
        try {
            TbReader editReader = new TbReader();
           editReader= this.setReader(getReader());
            editReader.setId(Integer.parseInt(typeid.trim()));
            uecon.edit(editReader);
            FacesMessage message = new FacesMessage("保存成功！");
            FacesContext.getCurrentInstance().addMessage(null, message);
        } catch (Exception e) {
            FacesMessage message = new FacesMessage("保存失败！");
            FacesContext.getCurrentInstance().addMessage(null, message);
        }
        return "reader";
    }
    public readeredit() {
    }

}

when I finnish editing the form data,i can hardly find a method to get the form value.Now i am confuing.Plz tell me.
