mongodb和springMVC整合

   在对mongodb和springmvc的整合是十分简单的，以maven项目为例。具体分为以下几步：

maven配置

  在整合之前需要导入jar包，在这里只需在pom.xml中加入依赖即可。

<!-- mongodb开始 --><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结束 -->

集群配置

applicationContext.xml

mongodb实例

mongodb对象模型

Book.java，具体代码如下

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")public class Book implements Serializable{@Idprivate String id;// 书名private String name;// 作者private String author;// 价格private float price;// 图书封面private String picture;// 图书存储量private Integer stock;// 售出量private int sale;// 图书简介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 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;}public void setSale(int sale) {this.sale = sale;}public String getMessage() {return message;}public void setMessage(String message) {this.message = message;}}

接口BookService.java

package com.book.book.service;/* * 图书管理 */public interface BookService {/* * 查询所有图书 */public String FindAll();/* * 根据图书名获取所有图书——模糊查询 *  * @name 图书名 *  * @return */public String getByName(String name);/* * 根据作者获取所有图书——模糊查询 *  * @author 作者 *  * @return */public String getByAuthor(String author);/* * 根据id获取所有图书 *  * @id 图书id *  * @return */public String getById(String id);}

接口实现

package com.book.book.service;import java.util.ArrayList;import java.util.List;import javax.ws.rs.Path;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.data.mongodb.core.MongoTemplate;import org.springframework.data.mongodb.core.query.Criteria;import org.springframework.data.mongodb.core.query.Query;import org.springframework.stereotype.Service;import com.book.book.model.Book;import net.sf.json.JSONObject;@Path("/Book")@Servicepublic class BookServiceImpl implements BookService {@Autowired@Qualifier("mongoTemplate")MongoTemplate mongoTemplate;public String FindAll() {JSONObject jsonObject = new JSONObject();try {List<Book> bookList = new ArrayList<Book>();bookList = mongoTemplate.findAll(Book.class);jsonObject.put("result", 1);jsonObject.put("msg", bookList);} catch (Exception e) {jsonObject.put("result", 0);jsonObject.put("msg", "接口异常，请联系管理员！");}return jsonObject.toString();}public String getByName(String name) {JSONObject jsonObject = new JSONObject();try {Criteria criteria = new Criteria();criteria.andOperator(Criteria.where("name").regex(".*?\\" + name + ".*"));List<Book> bookList = new ArrayList<Book>();bookList = mongoTemplate.find(new Query(criteria), Book.class);jsonObject.put("result", 1);jsonObject.put("msg", bookList);} catch (Exception e) {jsonObject.put("result", 0);jsonObject.put("msg", "接口异常，请联系管理员！");}return jsonObject.toString();}public String getByAuthor(String author) {JSONObject jsonObject = new JSONObject();try {Criteria criteria = new Criteria();criteria.andOperator(Criteria.where("author").regex(".*?\\" + author + ".*"));List<Book> bookList = new ArrayList<Book>();bookList = mongoTemplate.find(new Query(criteria), Book.class);jsonObject.put("result", 1);jsonObject.put("msg", bookList);} catch (Exception e) {jsonObject.put("result", 0);jsonObject.put("msg", "接口异常，请联系管理员！");}return jsonObject.toString();}public String getById(String id) {JSONObject jsonObject = new JSONObject();try {Criteria criteria = new Criteria();criteria.andOperator(Criteria.where("id").is(id));List<Book> bookList = new ArrayList<Book>();bookList = mongoTemplate.find(new Query(criteria), Book.class);jsonObject.put("result", 1);jsonObject.put("msg", bookList);} catch (Exception e) {jsonObject.put("result", 0);jsonObject.put("msg", "接口异常，请联系管理员！");}return jsonObject.toString();}}
