Spring 3 MVC and JSON example

In this tutorial, we show you how to output JSON data in Spring MVC framework.

Technologies used :

  1. Spring 3.2.2.RELEASE
  2. Jackson 1.9.10
  3. JDK 1.6
  4. Eclipse 3.6
  5. Maven 3

P.S In Spring 3, to output JSON data, just puts Jackson library in the project classpath.

1. Project Dependencies

Get Jackson and Spring dependencies.

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0"

2. Model

A simple POJO, later output this object as formatted JSON data. 


package com.mkyong.common.model;

public class Shop {

	String name;
	String staffName[];

	//getter and setter methods
	
}

3. Controller

Add @ResponseBody as return value. Wen Spring sees

  1. Jackson library is existed in the project classpath
  2. The mvc:annotation-driven is enabled
  3. Return method annotated with @ResponseBody

Spring will handle the JSON conversion automatically.

JSONController.java

package com.mkyong.common.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import com.mkyong.common.model.Shop;

@Controller
@RequestMapping("/kfc/brands")
public class JSONController {

	@RequestMapping(value="{name}", method = RequestMethod.GET)
	public @ResponseBody Shop getShopInJSON(@PathVariable String name) {

		Shop shop = new Shop();
		shop.setName(name);
		shop.setStaffName(new String[]{"mkyong1", "mkyong2"});
		
		return shop;

	}
	
}

4. mvc:annotation-driven

Enable mvc:annotation-driven in your Spring configuration XML file.

mvc-dispatcher-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

	<context:component-scan base-package="com.mkyong.common.controller" />

	<mvc:annotation-driven />

    1. Add this plugin in to your plugins inside of your pom.xml

      org.apache.tomcat.maven
      tomcat7-maven-plugin
      2.1

      /
      8080
      true

      Also add this dependency in your pom file:

      org.apache.tomcat.maven
      tomcat7-maven-plugin
      2.2

      if you are using eclipse run as>Maven build>under goals put “clean install tomcat7:run” (without quotations”)

      Then in your browser navigate to http://localhost:8080/rest/kfc/brands/kfc-kampar

  17. Thanks for this post. I have a doubt in configuring JSON Response prefix string. I have configured jsonPrefix in my project to prefix the response json with )]}’,n in MappingJson2HTTPMessageConverter class to fix common vulnerability. How could I see the response prefixed with the above string to confirm that this is working. I tried checking in chrome in the response string F12 -> Networks-> Json Response, however I could not find the string appended to the output. Could you please help me out with this?

  20. Thanks for this post!!
    I have a question, how do you configure your project ?
    Do you use only annotations setting the configuration into the code or do you prefer use the XML to set the configuration of frameworks like Spring mvc, spring batch or hibernate?

  26. Will the same work for jdk7 and spring 3.5?? Because I have created almost same project but its not working.I think there is some problem with jackson…I don’t think jackson 2.3 works with jdk7 correct me If I am wrong.

    I am not getting any error message but the ‘alert’ in which I am displaying my data is not getting displayed. However If I just send a normal string instead of a complex object its works fine.

    Can you please help?

  29. Hi to all ,

    I am new to Spring Boot ,i was face this problem of itteration but it’s resolved by using Jackson annotaions of @JsonBackReference and @JsonManagedReference and @JsonIdentityInfo after added these annotaions and bean configuration is everything fine .. but after i could not able to post the data as Json to a controller .Please suggest answer i am facing issue like

    1)Requested URL is http://localhost:8080/custMast/state (POST) that time 405 method is coming and JSON is
    {
    “custmastCountry” : {
    “id” : 1,
    “name” : “INDIA”,
    “customerAddresses” : [ ]
    },
    “name” : “MahaRashtra”,
    “createdOn” : null,
    “updatedOn” : null,
    “”custmastDistricts” : [ ],
    “customerAddresses” : [ ]
    }

    It’s giving this following error like

    Caused by: java.lang.IllegalArgumentException: Multiple back-reference properties with name ‘defaultReference’

    and my configuration is

    Here is My Configuration file for JSON in Spring BOOT

    @Bean
    public MappingJackson2HttpMessageConverter jackson2Converter() {
    MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
    converter.setObjectMapper(objectMapper());
    return converter;

    Object objectMapper = new ObjectMapper();
    // ((ObjectMapper) objectMapper).registerModule(new Hibernate4Module());
    ((ObjectMapper) objectMapper)
    .enable(SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS);
    // to allow serialization of “empty” POJOs (no properties to serialize)
    // (without this setting, an exception is thrown in those cases)
    ((ObjectMapper) objectMapper)
    .disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);
    // to write java.util.Date, Calendar as number (timestamp):
    ((ObjectMapper) objectMapper)
    .disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

    // DeserializationFeature for changing how JSON is read as POJOs:

    // to prevent exception when encountering unknown property:

      1. Yeah I was able to figure that out. I had an empty class(that was JAXB Generated). It was causing the issue. Like, public class DataIndicator{}. There was no variable within it. I changed the schema(that was in my case). Check if you have a similar empty class(that is a part of the response object that ur trying to convert it to JSON). Hope this helps!!

  70. Hi
    public ActionResult About()
    {
    List listStores = new List();
    listStores = this.GetResults(“param”);
    return Json(listStores, “Stores”, JsonRequestBehavior.AllowGet);
    }

    Using the above code i am able to get the below result :

    [{“id”:”1″,”name”:”Store1″,”cust_name”:”custname1″,”telephone”:”1233455555″,”email”:”[email protected]”,”geo”:{“latitude”:”12.9876″,”longitude”:”122.376237″}},{“id”:”2″,”name”:”Store2″,”cust_name”:”custname2″,”telephone”:”1556454″,”email”:”[email protected]”,”geo”:{“latitude”:”12.9876″,”longitude”:”122.376237″}},

    how would i able to get the result in below format ? would need stores at the beginning of the result.

    {
    “stores” : [
    {“id”:”1″,”name”:”Store1″,”cust_name”:”custname1″,”telephone”:”1233455555″,”email”:”[email protected]”,
    “geo”:{“latitude”:”12.9876″,”longitude”:”122.376237″}},{“id”:”2″,”name”:”Store2″,”cust_name”:”custname2″,”telephone”:”1556454″,”email”:”[email protected]”,”geo”:{“latitude”:”12.9876″,”longitude”:”122.376237″}} ] }

  71. If Mavan build doesn’t work replace the build tag with following one.
    Use Maven 3.x

    SpringMVC

    maven-compiler-plugin
    2.2

    1.6

  74. Hello,

    I am working on Spring MVC 3.0 JAXB & REST. I am new to these technologies. I am learning from your examples.

    In the above examples I didn’t understand the URL format. Could you explain it. where was the “rest” configured (http://localhost:8080/SpringMVC/rest/kfc/brands/kfc-kampar)

    I am getting 404 error when trying to execute this one in eclipse

    1. SpringMVC is the webapp (directory name in the web server’s webapps directory)

      In the webapp’s web.xml, the url mapping includes ‘rest’ as follows:

      <servlet-mapping>
		<servlet-name>mvc-dispatcher</servlet-name>
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>

      The controller takes you further in the url with the following annotation:
      @RequestMapping(“kfc/brands”)

      Whatever comes after that in the url is the ‘name’ PathVariable

      I hosted his example in Tomcat and it works.

      I discovered that the only misleading part in this example is the following in web.xml:

      <context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
	</context-param>

      Since the servlet name, as defined in web.xml, is mvc-dispatcher, the default dispatcher servlet name is mvc-dispatcher-servlet.xml, which coincides with the given name in the web.xml
      If you try to give any other name via this mechanism, the application will not work. You need to specify via servlet’s init-param as follows:

      <init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/applicationContext.xml</param-value>
		</init-param>

  75. Thank you… very helpful.

    Code snippet such as the following will allow UI to get to the controller:
    $(document).ready(function() {
    $.getJSON(“http://localhost:8080/SpringMVC/rest/kfc/brands/kfc-kampar”, function(shop) {
    alert(shop.name);
    });
    });

  76. When I run this example, its giving me Open/Save dialog on UI instead of printing JSOn data on browser.

    How would I print on browser ? Do I need to set any Accept header ?

  77. Hi,
    I like your way of explaining things, all your helps are appreciated.

    Can you please teach us how to interact from HTML (or jsp) to call an MVC controller , the controller will send data (as json)back to the page and update a div area.

    Thanks lot.

    1. Can you please post the reponse mapping code using json (I want to take json as an input to the spring controller and process the data)
