This article has two points to note:
First, add the validation jar package that needs to use the Hibrenate

A test for the Pojo class book

book.name.notEmpty=书名不能为空book.isbn.size.error=ISBN必须为13位
@NotEmpty"{book.name.notEmpty}")private String name;@Size1313"{book.isbn.size.error}")private String isbn;
Where message is the key name defined in the previous hint message file
The controller verification method code is as follows
@RequestMapping ("/addbookhandle") PublicModelandviewAddbookhandel(@Validated book Book,bindingresult Bindingresult) {Modelandview Modelandview =NewModelandview ();if(Bindingresult.haserrors ()) {//Get all the errorslist<objecterror> errors = Bindingresult.getallerrors (); for(Objecterror objecterror:errors) {//Print error MessagesSystem. out. println (Objecterror.getdefaultmessage ()); } modelandview.addobject (book);//If an error occurs, the original page of the jumpModelandview.setviewname ("Book/addbook"); }Else{Modelandview.setviewname ("Success"); }returnModelandview;}Sometimes, the properties to be validated are not immutable, sometimes only the titles need to be verified, sometimes only the ISBN is validated, so the validation rules need to be grouped.
Define several Java classes based on the number of groups to be divided, no inheriting classes or implementing interfaces, and no content is required in the class
Like creating ValidateType1 and ValidateType2 now.
Then define its group properties when defining the rule in the Pojo class, for example
@NotEmpty"{book.name.notEmpty}",groups = ValidationType1.class)private String name;@Size1313"{book.isbn.size.error}",groups = ValidationType2.class)private String isbn;
The validation rules that need to be executed are then added to the @validated annotations of the corresponding controller method, such as
publicaddUserHandle(@Validated(ValidationType1.class) User user,BindingResult bindingResult)
So in this method, only the title will be verified.
