以编程方式在adf视图对象中获取行

Question

每当我尝试以编程方式获取视图对象行时，我只获取第一行。请帮忙。

这里是我的代码：

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; 

Answer 1

如果用户和密码匹配您返回“成功”，但如果它不匹配，则返回“失败”。尝试代码，而不是：

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); 
}
