This problem occurs because:

1 @ResponseBody2@RequestMapping ("/updateproduct")3 @Transactional4      PublicProduct UpdateProduct2 (product product) {5Product Product1 =Productservice.load (Product.getproductid ());6         if(Product1! =NULL){7 Product1.setproductname (Product.getproductname ());8 Product1.setproductcre (Product.getproductcre ());9         }Ten          One         returnProduct1; A}

The load () used in this method gets to this piece of data in the database.

When using Load (), enter bug mode to see that although you get to this data, but you want to see, but found that the display of the object's fields are null.

But there is a value in it!!

This returns to the foreground, the foreground does not receive the value, will run out the exception:

Modify:

So we should modify the load () method to the Get () method

1 /**2 * For product modification Operation3      * @return4      */5 @ResponseBody6@RequestMapping ("/updateproduct")7 @Transactional8      PublicProduct UpdateProduct2 (product product) {9Product Product1 =Productservice.get (Product.getproductid ());Ten         if(Product1! =NULL){ One Product1.setproductname (Product.getproductname ()); A Product1.setproductcre (Product.getproductcre ()); -         } -          the         returnProduct1; -}

This will solve the problem!!
