我试图在jsf中调用一个使用primefaces的属性.但我有类型managedbean.PersonelBean上找不到的错误500.
我正在使用hibernate jsf和 spring. PersonelBean.java @ManagedBean(name="personelMB")
@SessionScoped
public class PersonelBean implements Serializable{
private static final long serialVersionUID = 1L;
@ManagedProperty(value="#{PersonelService}")
IPersonelService personelservice;
List<Personel> personelList;
private int personel_id;
private String pname;
private String pfamily;
private String paddress;
private String pphone;
public IPersonelService getPersonelservice() {
return personelservice;
}
public void setPersonelservice(IPersonelService personelservice) {
this.personelservice = personelservice;
}
public List<Personel> getPersonelList() {
personelList=new ArrayList<Personel>();
personelList.addAll(getPersonelservice().getPersonels());
return personelList;
}
public void setPersonelList(List<Personel> personelList) {
this.personelList = personelList;
}
//getter and setter method
public void addPersonel(){
Personel personel=new Personel();
personel.setPaddress(getPaddress());
personel.setPersonel_id(getPersonel_id());
personel.setPfamily(getPfamily());
personel.setPname(getPname());
personel.setPphone(getPphone());
getPersonelservice().addPersonel(personel);
}
}

但我有这个错误： description The server encountered an internal error () that prevented it from fulfilling this request.

我不知道出了什么问题,但我的addPersonel()效果很好. 解决方法
属性值表达式需要使用以下语法指定,不带get(或is)前缀且不带括号：
value="#{personelMB.personelList}"
