Learn to use Spring MockMVC to perform integration testing of Spring webmvc controllers.MockMVC class is part of Spring MVC test framework which helps in testing the controllers explicitly starting a Servlet container. In this MockMVC tutorial, we will use it along with Spring boot’s WebMvcTest class to execute Junit testcases which tests REST controller methods written for Spring boot 2.
This level can correspond to the old good controllers in Spring MVC. The purpose of handlers is to work with HTTP requests and responses and by this to connect a business logic with the outer world.
In spring mvc form submit tutorial, we learned about displaying displaying a form and submitting form data, including validating inputs using BindingResult.rejectValue().In this example, we will learn to build a more robust validator for EmployeeVO model object. This validator is custom implementation of Validator interface.

The preceding method declarations would try to find firstname anywhere in the given document. The lastname XML lookup is performed on the top-level of the incoming document.The above Exception is clearly saying that BeanExpressionResolver is not available at Runtime.

Spring MVC view layer: Thymeleaf vs. JSP.
