，同時運行這段代碼爲/facelet/crew/objectMapGossip.xhtml @14,94 value="#{objcetMapBean.searchCrewParam.staffNum}": Property 'staffNum' not readable on type java.lang.String我收到錯誤 請幫我從這個小錯誤。我是新來的JSF的東西基本如此stucking ...提前 感謝:-)如何從支持bean映射jsf中的對象？
這是我的支持bean ... import javax.faces.bean.ManagedBean;
@ManagedBean(name = "objcetMapBean")
public class ObjectMapGossip {
private SearchCrew1 searchCrewParam = new SearchCrew1("212","kart","asd");
public SearchCrew1 getSearchCrewParam() {
return searchCrewParam;
}
public void setSearchCrewParam(SearchCrew1 searchCrewParam) {
this.searchCrewParam = searchCrewParam;
}
public String search() {
return "success";
}
}
class SearchCrew1 {
public SearchCrew1() {
super();
}
/**
* @param staffNum
* @param surName
* @param rank
*/
public SearchCrew1(String staffNum, String surName, String rank) {
super();
this.staffNum = staffNum;
this.surName = surName;
this.rank = rank;
}
private String staffNum;
private String surName;
private String rank;
public String getStaffNum() {
return staffNum;
}
public void setStaffNum(String staffNum) {
this.staffNum = staffNum;
}
public String getSurName() {
return surName;
}
public void setSurName(String surName) {
this.surName = surName;
}
public String getRank() {
return rank;
}
public void setRank(String rank) {
this.rank = rank;
}
}
這是我的JSF頁面
