This is my controller file is where request mapping is done.

package webapp1;

import javax.servlet.ServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping(path="/store")
public class EmployeeController {
    @RequestMapping(method=RequestMethod.POST)
    public String saveEmployee(Employee employee,Model model) {
        System.out.println("eno:"+ employee.getEno()+"\n");
        System.out.println("name:"+ employee.getName()+"\n");
        System.out.println("address:"+ employee.getAddress()+"\n");
        System.out.println("contact:"+ employee.getContact()+"\n");
        System.out.println("email:"+ employee.getEmail()+"\n");
        System.out.println("salary:"+ employee.getSalary()+"\n");
        model.addAttribute("employee",employee);
         return "display";

    }

}

I have done getter and setter in separate file where getter and setter is done

package webapp1;

public class Employee {
    private Integer eno;
    private String name;
    private String address;
    private Double contact;
    private String email;
    private Double salary;
public  Employee() {
            }

    public Integer getEno() {
        return eno;
    }
    public void setEno(Integer eno) {
        this.eno = eno;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public Double getContact() {
        return contact;
    }
    public void setContact(Double contact) {
        this.contact = contact;
    }

    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public Double getSalary() {
        return salary;
    }
    public void setSalary(Double salary) {
        this.salary = salary;
    }

    public Employee(Integer eno, String name, String address, Double contact, String email, Double salary) {
        super();
        this.eno = eno;
        this.name = name;
        this.address = address;
        this.contact = contact;
        this.email = email;
        this.salary = salary;
    }



}

You might need to return the model instead of String in your "saveEmployee" method.In that way, you can get the values from the response.

Spring MVC example, Spring mvc example of form handling, learn to display and validate form, EmployeeVO.java <h2><spring:message code= "lbl.page" text= "Add New Employee" /></h2> This file is pretty straight forward and just displays the success message. is able to display form, and receiving submitted form with filled values. Recently I had a requirement where using Spring MVC we had to take inputs multiple rows of data from user. The form had many rows which user can edit and submit. Spring MVC provides very simple yet elegant way of collecting data from multiple rows from HTML form and store them in List of Beans in Java. Lets look at the requirement first.

If you are doing a POST I assume you are calling it with a body, in that case you need to add the tag @RequestBody to the param that will map the body, in this case I think is the Employee.

public String saveEmployee(@RequestBody Employee employee, Model model) {
    ...
}

CRUD Example using Spring MVC, Hibernate, Maven and MySQL , This application is Employee Management system where you can view or employee, create new empoloyee, edit or delete existing employee. CRUD Example using Spring MVC, Hibernate, Maven and MySQL In this post I am going to explain how to develop a Simple CRUD Output: Now lets hit� Spring MVC Form Binding. Before you start the tutorial, you need to understand how the Spring MVC form binding works. 1.1 In controller, you add an object into a model attribute.

From what I can understand, What you are doing in your controller is essentially making a new object of your Employee class and then trying to access the values from it. Therefor they are always null. I would recommend using mvc form with model attributes. In your current program rather than accessing values from Employee in your controller, Make a HttpservletRequest object and then access the values from it.

Or maybe you were trying to use @RequestBody in the controller. Hope it helps and put beans in your configuration file.

Here, we will use @Controler, @RequestMapping and @ModelAttribute annotations. To display the input form, we are going to use <form:form> tag of spring framework.

Spring MVC with JSP View, Spring MVC framework enables separation of modules namely Model, View, and and data-binding in the user interface are possible with spring form tags, JSP (Java Server Pages) is used as a view technology. <param-value>/WEB-INF/ mvc-dispatcher-servlet.xml</param-value> <welcome-file-list>. If you use Maven, you can run the application by using ./mvnw spring-boot:run. Alternatively, you can build the JAR file with ./mvnw clean package and then run the JAR file, as follows: java -jar target/gs-serving-web-content-0.1.0.jar

The Spring web MVC framework provides model-view-controller architecture and ready components that can be used to develop flexible and loosely coupled web applications. The MVC pattern results in separating the different aspects of the application (input logic, business logic, and UI logic), while providing a loose coupling between these elements.

Comments
  • The bean configurations <bean class ... should be in the bean configuration file. Follow some good tutorial e.g. tutorialspoint.com/springmvc/index.htm
  • Your input type lacks closing quotes too. Like tyoe=" " second quote is missing for all
  • Whatever documentation you're using is obsolete. The modern way to write Spring applications is to use Spring Boot, which takes care of most configuration for you. (I also recommend using Thymeleaf instead of JSP; it is similar but fixes several serious problems.)
