Not able to receive jsonData in spring controller

[abhi patil]

Hi Guys,
I am using spring 3.0.5.
I have simple json array and i want to receieve it in spring controller as list of state in this example

Json data is as below

[{"stateCode":"45","stateDesc":"Tamilnadu ","stateCodeNumber":"0","stdCode":"7890","isEdited":"true"},{"stateCode":"45","stateDesc":"Tamilnadu ","stateCodeNumber":"0","stdCode":"7890","isEdited":"true"},{"stateCode":"45","stateDesc":"Tamilnadu ","stateCodeNumber":"0","stdCode":"7890","isEdited":"true"}]

pojo

public class State {

	// A member
	private String stateDesc;
	// A member
	private String stateCode;
	private Integer stdCode;
	private Integer stateCodeNumber;

	// refernced member variable

	// getter and setter for refrenced entity

	public Integer getStdCode() {
		return stdCode;
	}

	public void setStdCode(Integer stdCode) {
		this.stdCode = stdCode;
	}

	public Integer getStateCodeNumber() {
		return stateCodeNumber;
	}

	public void setStateCodeNumber(Integer stateCodeNumber) {
		this.stateCodeNumber = stateCodeNumber;
	}

 

	public State() {
	 

	}

	// for referanced entity in constructor
	public State(String stateDesc, String stateCode) {
		this.stateDesc = stateDesc;
		this.stateCode = stateCode;
		// refernced member
	}

	// Generate the getters and setters for the fields
	public void setStateDesc(String stateDesc) {
		this.stateDesc = stateDesc;
	}

	public String getStateDesc() {
		return this.stateDesc;
	}

	public void setStateCode(String stateCode) {
		this.stateCode = stateCode;
	}

	public String getStateCode() {
		return this.stateCode;
	}

 
}

you will find some fields which are present in json are not found in pojo its because i dont require those fields they are simply redundant fields that i get from json.

Also my jsp dosent as ModelAttribute i.e i am not using fpring form tags it is designed as simple html tags

How can i get list of State in my controller ?

Hi,
Got it solved:
few things to take care if you are beginner
1. json data should be of the form

{stateList:
[{"stateCode":"45","stateDesc":"Tamilnadu ","stateCodeNumber":"0","stdCode":"7890","isEdited":"true"},{"stateCode":"45","stateDesc":"Tamilnadu ","stateCodeNumber":"0","stdCode":"7890","isEdited":"true"},{"stateCode":"45","stateDesc":"Tamilnadu ","stateCodeNumber":"0","stdCode":"7890","isEdited":"true"}]
}

2. Your object should contain ssetter and getter for the list. i.y spring controller should have a single object in as argument while that object should contain list of the objects that it needs to have
In my case it is State { public setStateList public .. getStateList }

3. Dont use json parameters whose properties are not present in the object it give an error if you want to use use annotation ignor-property // please check the annotation

Thanks and Regards
