Springboot（十六）SpringBoot整合mongoDB-CFANZ编程社区

新建一个springboot工程，pom.xml如下：

    </build>


</project>

application.yml如下：

spring:
  data:
    mongodb:
      database: mytest
      host: 192.168.94.151
      port: 27017
#spring.data.mongodb.uri=mongodb://username:password@IP:PORT/mongoDBName

dao层继承MongoRepository

package com.xhx.springboot.repository;

import com.xhx.springboot.entity.Account;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * @author xuhaixing
 * @date 2018/5/4 9:22
 */
@Repository
public interface AccountRepository extends MongoRepository<Account, String> {

    List<Account> findByName(String name);

}

同时还可以注入MongoTemplate操作数据库，我就不分层了，都注入到controller里了（只为演示功能）

package com.xhx.springboot.Controller;

import com.xhx.springboot.entity.Account;
import com.xhx.springboot.repository.AccountRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * @author xuhaixing
 * @date 2018/5/4 9:26
 */

@RestController
@RequestMapping(value = "account")
public class AccountController {

    @Autowired
    private AccountRepository accountRepository;

    @Autowired
    private MongoTemplate mongoTemplate;


    @RequestMapping(value = "save")
    public int save(@RequestBody Account account) {
        accountRepository.save(account);
        return 1;
    }

    @RequestMapping(value = "findAll")
    public List<Account> findAll() {
        return accountRepository.findAll();
    }

    @RequestMapping(value = "findById")
    public Account findById(String id) {
        return accountRepository.findById(id).get();
    }

    @RequestMapping(value = "findByName")
    public List<Account> findByName(String name) {
        return accountRepository.findByName(name);
    }

    @RequestMapping(value = "findAll2")
    public List<Account> findAll2() {
        return mongoTemplate.findAll(Account.class);
    }

}
