springboot集成mongodb使用mongoTemplate和MongoRepository

springboot集成mongodb使用mongoTemplate和MongoRepository

在pom文件引入spring-boot-starter-data-mongodb依赖：

	
			org.springframework.boot
			spring-boot-starter-data-mongodb
		

数据源的配置 

如果mongodb端口是默认端口，并且没有设置密码，可不配置，sprinboot会开启默认的。

spring.data.mongodb.uri=mongodb://localhost:27017/mydb

如何mongodb设置了密码，这样配置：

spring.data.mongodb.uri=mongodb://kerry:123456@localhost:27017/mydb

如果多个节点集群配置

#more ip cluster
#spring.data.mongodb.uri=mongodb://user:pwd@ip1:port1,ip2:port2/database

定义一个实体类

package com.powercn.probe.model;

public class Customer {
	
	private String id;
	private String probMac;
	private String devcMac;
	private String inTime;
	private String outTime;
	private String rssi;
	
	public Customer(String probMac, String devcMac, String inTime,
			String outTime, String rssi) {
		this.probMac = probMac;
		this.devcMac = devcMac;
		this.inTime = inTime;
		this.outTime = outTime;
		this.rssi = rssi;
	}
	
	
	public String getId() {
		return id;
	}


	public void setId(String id) {
		this.id = id;
	}


	public String getInTime() {
		return inTime;
	}
	public void setInTime(String inTime) {
		this.inTime = inTime;
	}
	public String getOutTime() {
		return outTime;
	}
	public void setOutTime(String outTime) {
		this.outTime = outTime;
	}
	public String getProbMac() {
		return probMac;
	}
	public void setProbMac(String probMac) {
		this.probMac = probMac;
	}
	public String getDevcMac() {
		return devcMac;
	}
	public void setDevcMac(String devcMac) {
		this.devcMac = devcMac;
	}
	public String getRssi() {
		return rssi;
	}
	public void setRssi(String rssi) {
		this.rssi = rssi;
	}
	@Override
	public String toString() {
		return "Customer [probMac=" + probMac + ", devcMac=" + devcMac
				+ ", inTime=" + inTime + ", outTime=" + outTime + ", rssi="
				+ rssi + "]";
	}
}

定义repository接口继承mongoRepository接口

public interface CustomerRepository extends MongoRepository {
	
	 public Customer findByDevcMac(String devcMac);

}

写一个接口，继承MongoRepository，这个接口有了几本的CURD的功能。如果你想自定义一些查询，比如根据firstName来查询，获取根据lastName来查询，只需要定义一个方法即可。注意firstName严格按照存入的mongodb的字段对应。在典型的 Java的应用程序，写这样一个接口的方法，需要自己实现，但是在springboot中，你只需要按照格式写一个接口名和对应的参数就可以了，因为springboot已经帮你实现了。

测试 ，springboot会自动注入mongotemplate

package com.powercn.probe.controller;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Enumeration;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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

import com.powercn.probe.dao.CustomerRepository;
import com.powercn.probe.model.Customer;

@Controller
public class AccController {
	
	@Autowired
	private MongoTemplate mongoTemplate;
	
	@Autowired
	private CustomerRepository repository;
	
	
	@RequestMapping("/probe/wp")
	@ResponseBody
	public Object wpPhp(HttpServletRequest request,HttpServletResponse response){
		SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
		System.out.println(sdf.format(new Date())+"-->prob post begin.......");
		try {
			Enumeration enums = request.getParameterNames();
			while (enums.hasMoreElements()) {
				String name = enums.nextElement();
				System.out.println("data:"+name+"="+request.getParameter(name));
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		Customer cus = repository.findByDevcMac("FCE998A1E7EF");
		System.out.println(cus.toString());
		
		Customer cus1=mongoTemplate.findOne(new Query(Criteria.where("devcMac").is("FCE998A1E7EF")), Customer.class);
		System.out.println(cus1);
				System.out.println(sdf.format(new Date())+"-->wphp post end.......");
		
				return "OK";
	}
}
