Spring3 MVC Consolidation JSON Instance __json

Original link: http://www.mkyong.com/spring-mvc/spring-3-mvc-and-json-example/

In a previous article about how Spring MVC consolidates JSON and returns JSON format, this article is very concise, so just translate it a little bit and reprint it.

=============================================================================================================== =====================

This tutorial will show you how to return JSON-formatted content in the Spring MVC framework.

Technology used: Spring 3.2.2.RELEASE Jackson 1.9.10 JDK 1.6 Eclipse 3.6 Maven 3

PS: In spring 3, just put the Jackson bag under the classpath root directory. 1. Project Dependency Configuration (Note: This part is relative to the MAVEN project, if it is not a MAVEN managed project, you can ignore this part, directly to the relevant Sring package and Jackson package into the Lib library can be.) ）

Configure Jackson and Spring dependencies

Pom.xml is as follows

<project xmlns= "http://maven.apache.org/POM/4.0.0" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi: schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd" > <modelversion >4.0.0</modelVersion> <groupId>com.mkyong.common</groupId> <artifactid>springmvc</ artifactid> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name> Springmvc Json webapp</name> <url>http://maven.apache.org</url> <properties> <spring.ver Sion>3.2.2.release</spring.version> <jackson.version>1.9.10</jackson.version> < Jdk.version>1.6</jdk.version> </properties> <dependencies> <!--Spring 3 dependencies--&G

2. Model

A simple Pojo object that will later be converted to JSON-formatted data output.

Package Com.mkyong.common.model;
 
public class Shop {
 
	String name;
	String staffname[];
 
	Getter and Setter Methods
 
}

  3. Controller

Add @responsebody annotations before the method name. If the Spring Discovery Project Lib Library contains the Jackson package spring enabled the Mvc:annotation-driven MVC annotation Configuration return method using the @responsebody annotation

Spring automatically transforms the JSON.

The Jsoncontroller.java is as follows:

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 annotation

Enable Mvc:annotation-driven annotations in your spring configuration

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/>
 
</ Beans>
