javaWeb deleted and a plurality of data

First, write dao

// Delete The ID 
@Delete ( "Delete from Product ID WHERE ID = # {}") 
public void Delete (ID Integer); 
two, and write a service implementation class

// delete a single 
public void Delete (ID Integer); 
// delete multiple 
public void deletes (Integer [] ids );

@Override 
public void Delete (Integer ID) { 

    productDao.delete (ID); 
} 
// delete a plurality of data according to the ID 
public void Deletes (Integer [] IDS) { 
    IF (IDS = null!) { 
        For (Integer ID: IDS ) { 
            productDao.delete (ID); 
        } 
    } 
}

Third, the write controller controller

// delete a data 
@RequestMapping ( "/ Delete") 
public String Delete (Integer ID) { 
    productService.delete (ID); 
    return "the redirect: findByProduct"; 
} 
// delete a plurality of data 
@RequestMapping ( "/ deletes") 
String Deletes public (Integer [] IDS) { 
    productService.deletes (IDS); 
    return "redirect: findByProduct"; (redirect page refresh) 
} 

Fourth, writing web documents

<button type="button" class="btn btn-default" title="删除"
   onclick='deletes()'>
   <i class="fa fa-trash-o"></i> 删除
</button>

<form ID = "delForm" Action = "$ {} pageContext.request.contextPath / Product / Deletes" Method = "POST"> 
... (herein, within the form table column name is omitted)

<Td> <input name = "ids" type = "checkbox" value = "$ {product.id}"> </ td> (checkbox value box will go to the value, for a plurality of ID according to the value obtained by deleting the )

... (omitted where the data in the table form corresponding to the columns)

<Button type = "button" class = "btn bg-olive btn-xs" onclick = 'delOne ($ {product.id})'> Delete </ button> (delete individual data)

</from>

<Script of the type = "text / JavaScript"> 
   // delete a single 
   function DeLone (the above mentioned id) { 
      IF (Confirm The ( "Are you sure you want to do ????")) { 
         // delete 
         location.href = "$ {pageContext ? .request.contextPath} / Product / the delete the above mentioned id = "+ the above mentioned id; 
      } 
   } 
   function deletes () { 
      IF (Confirm The (" Are you sure you want to do ???? ")) { 
         var delForm = $ (" # delForm " ); 
         delForm.submit (); 
      } 
   } 
</ Script>
