Spring MVC Custom Validation
The Spring MVC framework allows us to perform custom validations. In such case, we declare own annotations. We can perform validation on the basis of own business logic.
Spring MVC Custom Validation Example
In this example, we use both pre-defined annotations as well as custom annotations to validate user input.
1. Add dependencies to pom.xml file.
pom.xml
2. Create the bean class
Employee.java
3. Create the controller class
EmployeeController.java
4. Create the validator annotation
Password.java
5. Create the validator class
PasswordConstraintValidator.java
6. Provide the entry of controller in the web.xml file
web.xml
7. Define the bean in the xml file
spring-servlet.xml
8. Create the requested page
index.jsp
9. Create the other view components
viewpage.jsp
final.jsp
Output:
Here, we entered the password without having “jtp” sequence.
Now, we entered the password having “jtp” sequence.
