The same problem arises in the interaction between the browser and the server, as requests and responses are mostly parsed into strings. Now, you should have understood the relationship between validation, Data Binding, Type conversion, and they are independent but co-compatible with each other. Premise Before you know more, you should know two key concepts: JavaBean and properties. JavaBean is a simple class, non-parame

There is a basic method of data validation in spring 4.0 annotation data validation 1. or the Pojo: PackageCom.suyin.pojo;ImportJava.lang.reflect.Field;ImportOrg.hibernate.validator.constraints.NotBlank; Public classpeople {Private intID; @NotBlankPrivateString name; PrivateString address; Private intAge ; Public Final intgetId () {returnID; } Public Final v
Background check has a lot of tools, the first use is @valid, this is relatively simple, does not support the packet checksum.
Spring encapsulates the @valid with @validated, which satisfies the packet checksum.
In fact, a group is added to group the checksum rules, and then the @validated is specified in the group to verify.
Specific examples refer to the following blog:
