pom整合

<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.9.8.RELEASE</version>
</dependency>
<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongo-java-driver</artifactId>
<version>2.14.2</version>
</dependency>

简单使用一下

@Service
public class TestMongodbServerImpl implements TestMongodbServer {
@Autowired
private MongoOperations mongoOperations;

@Override
public void test() {
List<WxRes> list = new ArrayList<WxRes>();
WxRes wx = new WxRes();
WxRes wx2 = new WxRes();
wx.setId("111111");
wx.setOrderId("22222");
list.add(wx);
wx2.setId("33333");
wx2.setOrderId("44444");
list.add(wx2);
mongoOperations.insert(list, WxRes.class);
}

插入成功

 

 

 

增删查改：

//save存在则更新，不存在则插入
@Override
public void save(WxRes wxRes) {
WxRes wx = new WxRes();
wx.setId("111111");
wx.setOrderId("2222233");
mongoOperations.save(wx);
}

//insert存在则不做处理，不存在则插入
@Override
public void insert(WxRes wxRes) {
WxRes wx = new WxRes();
wx.setId("111111");
wx.setOrderId("2222233");
mongoOperations.insert(wx);
}

//根据userid删除文档
@Override
public void remove(String uid) {
mongoOperations.remove("111111");
}

//根据id更新文档
@Override
public int update(WxRes wxRes) {

Query qu = new Query();
qu.addCriteria(Criteria.where("id").is("111111"));
Update up = new Update();
up.set("id", "8888888");
// int n = mongoOperations.updateFirst(qu, up, WxRes.class).getN();//只修改第一个
int n2 = mongoOperations.updateMulti(qu, up, WxRes.class).getN();//修改所有
return n2;

}

//单条件查询，find查询所有
@Override
public List<WxRes> findByUid(String uid) {
Query qu = new Query();
qu.addCriteria(Criteria.where("id").is("33333"));
return mongoOperations.find(qu,WxRes.class);
}

//多条件查询，find查询所有
@Override
public List<WxRes> findByUidAndTimestamp(String uid, String name) {
Query qu = new Query();
qu.addCriteria(Criteria.where("id").is("33333").and("orderId").is("44444"));
return mongoOperations.find(qu, WxRes.class);
}

//根据uid分页查询
@Override
public List<WxRes> page(int page, String uid) {
Query qu = new Query();
qu.addCriteria(Criteria.where("id").is("33333"));
qu.with(new Sort(new Sort.Order(Sort.Direction.DESC,"id")));
qu.limit(5);
qu.skip((page-1)*5);
return mongoOperations.find(qu, WxRes.class);
}
