Bean property 'favLang' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
I have created a spring mvc project with simple form and model. On running the project it gives below error: Invalid property 'favLang' of bean class [com.springdemo.mvc.Student]: Bean property 'favLang' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
Student.java
package com.springdemo.mvc;
import java.util.LinkedHashMap;
public class Student {
private String firstName;
private String lastName;
private String countryName;
private LinkedHashMap<String, String> countryOptions;
private String favLang;
public Student() {
countryOptions = new LinkedHashMap<>();
countryOptions.put("BR", "Brazil");
countryOptions.put("IN", "India");
countryOptions.put("FR", "France");
countryOptions.put("GE", "Germany");
}
public LinkedHashMap<String, String> getCountryOptions() {
return countryOptions;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getCountryName() {
return countryName;
}
public void setCountryName(String countryName) {
this.countryName = countryName;
}
public String getFavLang() {
return favLang;
}
public void setFavLang(String favLang) {
this.favLang = favLang;
}
}
Student-Controller
package com.springdemo.mvc;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/student")
public class StudentController {
@RequestMapping("/showForm")
public String showForm(Model theModel) {
//create a new student object
Student theStudent=new Student();
//add student object as model attribute
theModel.addAttribute("student", new Student());
return "student-form";
}
@RequestMapping("/processForm")
public String processForm(@ModelAttribute("student") Student theStudent) {
System.out.println("theStudent: "+theStudent.getFirstName());
return "student-confirmation";
}
}

You need to add object in to modelAndView return that from StudentController. Check following changes in code and run project.
Student.java
public class Student {
private String firstName;
private String lastName;
private String countryName;
private LinkedHashMap<String, String> countryOptions;
private String favLang;
public Student() {
countryoptions = new LinkedHashMap<String, String>();
countryoptions.put("BR", "Brazil");
countryoptions.put("IN", "India");
countryoptions.put("FR", "France");
countryoptions.put("GE", "Germany");
}
public LinkedHashMap<String, String> getCountryOptions() {
return countryoptions;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getCountryname() {
return countryname;
}
public void setCountryname(String countryname) {
this.countryname = countryname;
}
public LinkedHashMap<String, String> getCountryoptions() {
return countryoptions;
}
public void setCountryoptions(LinkedHashMap<String, String> countryoptions) {
this.countryoptions = countryoptions;
}
public String getFavlang() {
return favlang;
}
public void setFavlang(String favlang) {
this.favlang = favlang;
}
}
Student-Controller.java
@Controller
public class StudentController {
@RequestMapping(value = "/showForm", method = RequestMethod.GET)
public ModelAndView showRegister(HttpServletRequest request, HttpServletResponse
response) {
ModelAndView mav = new ModelAndView("student-form");
mav.addObject("student", new Student());
return mav;
}
@RequestMapping(value = "/processForm", method = RequestMethod.POST)
public ModelAndView addUser(HttpServletRequest request, HttpServletResponse
response,@ModelAttribute("student") Student student) {
ModelAndView mav = new ModelAndView("student-confirmation");
mav.addObject("firstname", student.getFirstname());
mav.addObject("favName", student.getFavlang());
return mav;
}
}
