Question

每当我尝试以编程方式获取视图对象行时，我只会获得第一行。请帮忙。

这是我的代码：

BindingContext BContext=BindingContext.getCurrent();
System.out.println(1);
//BindingContainer bindings= (BindingContainer)bctx.getCurrent().getCurrentBindingsEntry();
BindingContainer bindings = (BindingContainer)BContext.getCurrent().getCurrentBindingsEntry();
DCBindingContainer dc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iterBind= dc.findIteratorBinding("UsersView1Iterator");
ViewObject vo=iterBind.getViewObject();  
vo.executeQuery();
RowSetIterator rsIterator = vo.createRowSetIterator(null);
rsIterator.reset();
while (rsIterator.hasNext()) {
       Row row = rsIterator.next();
       String s=(String)row.getAttribute("Username");
       String s1=(String)row.getAttribute("Password");
       System.out.println(row.getAttribute("Username"));
       System.out.println(row.getAttribute("Password"));
       if(s.equals(user) && s1.equals(Pass)){
            System.out.println(row.getAttribute("Username"));
            FacesMessage fm=new FacesMessage(message.toString());
            fm.setSeverity(FacesMessage.SEVERITY_INFO);
            FacesContext context=FacesContext.getCurrentInstance();
            context.addMessage(null, fm);
            System.out.println("valid");
            return "Success";
       }else{
            FacesMessage fm=new FacesMessage(message1.toString());
            fm.setSeverity(FacesMessage.SEVERITY_INFO);
            FacesContext context=FacesContext.getCurrentInstance();
            System.out.println("invalid");
            context.addMessage(null, fm);System.out.println(20);   
            return "fail";
       }       
 }  
 rsIterator.closeRowSetIterator();  
 return null;

如果用户和密码匹配，则返回“成功”但如果不匹配，则返回“失败”。请尝试使用该代码：

while (rsIterator.hasNext()) {
       Row row = rsIterator.next();
       String s=(String)row.getAttribute("Username");
       String s1=(String)row.getAttribute("Password");
       System.out.println(row.getAttribute("Username"));
       System.out.println(row.getAttribute("Password"));
       if(s.equals(user) && s1.equals(Pass)){
            System.out.println(row.getAttribute("Username"));
            FacesMessage fm=new FacesMessage(message.toString());
            fm.setSeverity(FacesMessage.SEVERITY_INFO);
            FacesContext context=FacesContext.getCurrentInstance();
            context.addMessage(null, fm);
            System.out.println("valid");
            return "Success";
       }       
 }
rsIterator.closeRowSetIterator();  
FacesMessage fm=new FacesMessage(message1.toString());
fm.setSeverity(FacesMessage.SEVERITY_INFO);
FacesContext context=FacesContext.getCurrentInstance();
System.out.println("invalid");
context.addMessage(null, fm);System.out.println(20);   
return "fail";

试试这个

DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcIteratorBindings =
bindings.findIteratorBinding("DocumentsView1Iterator");

// Get all the rows of a iterator
Row[] rows = dcIteratorBindings.getAllRowsInRange();
for (Row row : rows) {
    String Username=(String)row.getAttribute("Username");
    String Password=(String)row.getAttribute("Password");
    System.out.println("Check"+depname);
}
