MongoDB and SPRINGMVC Integration

The integration of MongoDB and SPRINGMVC is very simple, taking the MAVEN project as an example. The following steps are specifically divided: maven configuration

Before consolidating, you need to import jar packages, where you can simply add dependencies to the Pom.xml.

<!--mongodb start-->
	<dependency>
		<groupId>org.mongodb</groupId>
		< artifactid>mongo-java-driver</artifactid>
		<version>3.3.0</version>
	</ dependency>
	<dependency>
		<groupId>org.springframework.data</groupId>
		< artifactid>spring-data-mongodb</artifactid>
		<version>1.7.1.RELEASE</version>
	</dependency>
<!--MongoDB end-->

MongoDB Instance MongoDB Object Model

Book.java, the specific code is as follows

Package Com.book.book.model;

Import java.io.Serializable;
Import Org.springframework.data.annotation.Id;

Import org.springframework.data.mongodb.core.mapping.Document;
	@Document (collection = "book") The public class book implements serializable{@Id private String Id;
	The title is private String name;
	Author Private String author;
	Prices private float price;
	Book cover private String picture;
	Books Storage reserves private Integer stock;
	Volume sold private int sale;

	Book Introduction private String message;
	Public String GetId () {return id;
	public void SetId (String id) {this.id = ID;
	Public String GetName () {return name;
	public void SetName (String name) {this.name = name;
	Public String Getauthor () {return author;
	} public void Setauthor (String author) {this.author = author;
	public float GetPrice () {return price;
	public void Setprice (float price) {this.price = Price;
	Public String Getpicture () {return to picture; public void Setpicture (String Picture) {this.picture = picture;
	Public Integer Getstock () {return-stock;
	public void Setstock (Integer-stock) {this.stock = stock;
	public int Getsale () {return sale;
	The public void Setsale (int sale) {This.sale = sale;
	Public String GetMessage () {return message;
	public void Setmessage (String message) {this.message = message;
 }

}

Interface Bookservice.java

Package com.book.book.service;
 * * * Library
 Management
/public interface Bookservice {* *
	 query All
	 books
	/public String findall ();
	 * * Access to all books by book name--Fuzzy query * * 
	 @name Book name

	String Getbyname ( String name);
	 * * * To obtain all books from the author-fuzzy query
	 * * 
	 @author Author

	String Getbyauthor ( String author);
