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：

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-mongodb</artifactId></dependency>

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;}@Overridepublic 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<Customer, String> { 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;@Controllerpublic class AccController {@Autowiredprivate MongoTemplate mongoTemplate;@Autowiredprivate CustomerRepository repository;@RequestMapping("/probe/wp")@ResponseBodypublic Object wpPhp(HttpServletRequest request,HttpServletResponse response){SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");System.out.println(sdf.format(new Date())+"-->prob post begin.......");try {Enumeration<String> 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";}}
