MongoDB SpringBoot整合（二十一）

1、application.properties文件添加MongoDB配置信息

## mongodb
spring.data.mongodb.uri=mongodb://root:[e-mail]:27017/?authSource=admin&authMechanism=SCRAM-SHA-1
spring.data.mongodb.database=Test

2、在pom.xml中添加依赖

<dependency>
	   <groupId>org.springframework.boot</groupId>
	   <artifactId>spring-boot-starter-data-mongodb</artifactId>
	   <version>2.1.5.RELEASE</version><!-- 不指定默认下载2.1.3版本，会出问题 -->
	</dependency>

3、entity

package com.zit.mongodb.entity;

import java.util.Date;

public class Book {
	private String _id;
	private String title;
	private String[] author;
	private Date published_date;
	private Integer pages;
	private String language;
	private String[] checkout;
	private String[] myPush;
	private Integer available1;
	
	public String get_id() {
		return _id;
	}
	public void set_id(String _id) {
		this._id = _id;
	}
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public String[] getAuthor() {
		return author;
	}
	public void setAuthor(String[] author) {
		this.author = author;
	}
	public Date getPublished_date() {
		return published_date;
	}
	public void setPublished_date(Date published_date) {
		this.published_date = published_date;
	}
	public Integer getPages() {
		return pages;
	}
	public void setPages(Integer pages) {
		this.pages = pages;
	}
	public String getLanguage() {
		return language;
	}
	public void setLanguage(String language) {
		this.language = language;
	}
	public String[] getCheckout() {
		return checkout;
	}
	public void setCheckout(String[] checkout) {
		this.checkout = checkout;
	}
	public String[] getMyPush() {
		return myPush;
	}
	public void setMyPush(String[] myPush) {
		this.myPush = myPush;
	}
	public Integer getAvailable1() {
		return available1;
	}
	public void setAvailable1(Integer available1) {
		this.available1 = available1;
	}
}

4、dao

package com.zit.mongodb.dao.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.data.mongodb.core.MongoTemplate;

import com.zit.mongodb.dao.BookDao;
import com.zit.mongodb.entity.Book;

@Component
public class BookDaoImpl implements BookDao{

	@Autowired
	private MongoTemplate mongoTemplate;
	
	@Override
	public void saveBook(Book book) {
		mongoTemplate.save(book);
	}

	@Override
	public List<Book> getBooks() {
		List<Book> result = mongoTemplate.findAll(Book.class);
		return result;
	}

}

5、service

package com.zit.mongodb.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.zit.mongodb.dao.BookDao;
import com.zit.mongodb.entity.Book;
import com.zit.mongodb.service.BookService;

@Service
public class BookServiceImpl implements BookService {
	@Autowired
	private BookDao bookDao;

	@Override
	public void saveBook(Book book) {
		bookDao.saveBook(book);
	}

	@Override
	public List<Book> getBooks() {
		List<Book> result = bookDao.getBooks();
		return result;
	}

}

6、controller

package com.zit.mongodb.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.zit.mongodb.entity.Book;
import com.zit.mongodb.service.BookService;

@RestController
@RequestMapping("mongo")
public class MongoDBController {
	@Autowired
	private BookService bookService;
	
	@RequestMapping("books")
	public List<Book> getBooks(){
		List<Book> result = bookService.getBooks();
		return result;
	}
}

7、集合sql

/ ----------------------------
// Collection structure for book
// ----------------------------
db.getCollection("book").drop();
db.createCollection("book");

// ----------------------------
// Documents of book
// ----------------------------
db.getCollection("book").insert([ {
    _id: 15112345678,
    title: "MongoDB",
    author: [
        "Tom",
        "Jerry"
    ],
    "published_date": ISODate("2019-01-01T00:00:00.000Z"),
    pages: 216,
    language: "Chinese",
    checkout: [
        {
            by: "joe",
            date: ISODate("2019-01-01T00:00:00.000Z")
        },
        {
            by: "abc",
            date: ISODate("2019-07-03T08:47:13.112Z")
        },
        {
            by: "abc",
            date: ISODate("2019-07-03T11:28:44.8Z")
        },
        {
            by: "abc",
            date: ISODate("2019-07-03T11:28:47.545Z")
        }
    ],
    myPush: [ ],
    available1: 7
} ]);
