在此页面中,要么h:commandButton
不会触发托管 bean 中的操作方法,但是当我单击按钮时,它会重新加载当前页面。我不知道为什么请帮忙。

我的 searchView 托管 bean 是会话范围的,这里是托管 bean 中的 prepareSearchResultView() 方法;
public String prepareSearchResultView(){
this.searchResultList = searchCustomer();
if(!this.searchResultList.isEmpty()){
this.citizenSearchResultList = getCitizenSearchList();
this.orgSearchResultList = getOrganizationSearchList();
if(getCitizenSearchList().getRowCount() >0){
return "citizensearchlist";
}else if(getOrganizationSearchList().getRowCount()>0){
return "orgsearchlist";
}
}else
return "nosearchresult";
//FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO, "no such result", "no such result"));
return null;
}
和 getSearchType() 方法
public Map<String, Object> getSearchType(){
Map<String, Object> returnMap = new LinkedHashMap<String, Object>();
if(loginview.isAbleToGetCitizenInfo() || loginview.isUserAdmin()){
returnMap.put("searchtype1", "searchcitizenbyregno");
returnMap.put("searchtype2", "searchcitizenbyname");
}
if(loginview.isAbleToGetOrgInfo() || loginview.isUserAdmin()){
returnMap.put("searchtype3", "searchorgbyregno");
returnMap.put("searchtype4", "searchgorgbyname");
returnMap.put("searchtype5", "searchorgbystateregno");
}
return returnMap;
}
