org.springframework.beans.NotReadablePropertyException

[Raaja Gotluru]

Hi,

I have just started Spring. I am trying an example but I am getting the following exception. As per the message I have checked the bean class but didnt find the solution.

org.springframework.beans.NotReadablePropertyException: Invalid property 'name' of bean class [java.lang.String]: Bean property 'name' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

My code is :

user.java

private String name;
	private String password;
	private String gender;
	private String country;
	private String aboutYou;
	private String[] community;
	private Boolean mailingList;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getGender() {
		return gender;
	}
	public void setGender(String gender) {
		this.gender = gender;
	}
	public String getCountry() {
		return country;
	}
	public void setCountry(String country) {
		this.country = country;
	}
	public String getAboutYou() {
		return aboutYou;
	}
	public void setAboutYou(String aboutYou) {
		this.aboutYou = aboutYou;
	}
	public String[] getCommunity() {
		return community;
	}
	public void setCommunity(String[] community) {
		this.community = community;
	}
	public Boolean getMailingList() {
		return mailingList;
	}
	public void setMailingList(Boolean mailingList) {
		this.mailingList = mailingList;
	}

Where I am doing wrong. Guide me in executing this.

Thanks.

Hi,

Some one help in solving this.

In your UserController -

mav.addObject("command", "userForm"); 

Instead of just the String "userForm", you're probably wanting to place an instance of the model class here... something like -

User user = new User();
mav.addObject("command", user);

You also probably want to pass a User instance into the method that handles your form POST -

public String create(@ModelAttribute("newContact") User user, BindingResult result, SessionStatus status){
