java操作Mongodb,Spring-data-mongo简单配置

这段时间一直在用mongodb，但是却没有配置过Spring操作mongodb。今天配了下，顺便把代码贴出来。官方文档：http://docs.spring.io/spring-data/mongodb/docs/current/reference/html/#mongodb-connectorsmongodata.xml

得到mongoTemplate后就很容易操作了， 增删改查跟在mongo命令窗口差不多。数据库、表、表结构查询效果附上官方的一些例子:

查找:

BasicQuery query = new BasicQuery("{ age : { $lt : 50 }, accounts.balance : { $gt : 1000.00 }}");
List<Person> result = mongoTemplate.find(query, Person.class);

List<Person> result = mongoTemplate.find(query(where("age").lt(50)
.and("accounts.balance").gt(1000.00d)), Person.class);

Point point = new Point(-73.99171, 40.738868);
List<Venue> venues =
template.find(new Query(
Criteria.where("location").nearSphere(point).maxDistance(0.003712240453784)),
Venue.class);

Query query = TextQuery.searching(new TextCriteria().matchingAny("coffee", "cake")).sortByScore();List<Document> page = template.find(query, Document.class);

更新

WriteResult wr = mongoTemplate.updateMulti(new Query(where("accounts.accountType").is(Account.Type.SAVINGS)),new Update().inc("accounts.$.balance", 50.00), Account.class);

插入

Person p = new Person("Bob", 33);mongoTemplate.insert(p);Person qp = mongoTemplate.findOne(query(where("age").is(33)), Person.class);
