Spring MVC, MongoDB and Eclipse Mars. How to use - spring

Question

Need a example of using Spring MVC, MongoDB with CRUD operation on Eclipse Mars 2.
I tried many example from internet, but they didn;t specified about placement of files. Placement of file is important part of any web project. Please specify them.
As I am learning , I have used Maven and installed all latest jars

Answer 1

You can think about spring-data-mongodb . Using mongotemplate its very easy to manipulate your db using spring app.
Step 1: add dependency to your pom.xml
<!-- MongoDB -->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.1.0.RELEASE</version>
</dependency>
Step 2: you need to define bean in your configuartion xml file. i.e. servlet-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xmlns:beans="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/data/mongo
http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">
<mongo:mongo id="mongo" host="192.168.1.85" port="27017" />
<mongo:db-factory id="mongoFactory" host="192.168.1.85"
port="27017" dbname="xxxxx" />
<beans:bean id="mongoTemplate"
class="org.springframework.data.mongodb.core.MongoTemplate">
<beans:constructor-arg ref="mongoFactory" />
</beans:bean>
<!-- Your configuration here-->
Note: Remove unnecessary part in your case.
Step 3: You can autowired mongo template in your DAO layer.
#Autowired
#Qualifier("mongoTemplate")
private MongoTemplate mt;
you can find ,update,insert using mt
e.g. mt.find(new Query(Criteria.where("id").is("i123")));
Hope so it will help you..
