spring整合mongo及调用
spring整合mongo（maven工程下）：
1、web.xml文件中配置需要加载的配置文件：
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:/datasource/*.xml classpath:/ibatis/sql-map-client-config.xml classpath:/context/ctx*.xml </param-value> </context-param>
2、datasource文件夹下新建common-config.xml文件，配置mongo数据源：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mongo="http://www.springframework.org/schema/data/mongo" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="order" value="2" /> <property name="ignoreUnresolvablePlaceholders" value="true" /> <property name="locations"> <list> <value>file:${CONFIG_DIR_PATH}/village.properties</value> <value>file:${CONFIG_DIR_PATH}/mongo.properties</value> <value>file:${CONFIG_DIR_PATH}/../system-config/jdbc.village.properties</value> </list> </property> </bean> <!-- mongo config --> <!-- Default bean name is 'mongo' --> <mongo:mongo id="mongoData" host="${mongo.ip}" port="${mongo.port}"> <mongo:options connections-per-host="${mongo.connections-per-host}" threads-allowed-to-block-for-connection-multiplier="${mongo.threads-allowed-to-block-for-connection-multiplier}" connect-timeout="${mongo.connect-timeout}" max-wait-time="${mongo.max-wait-time}" auto-connect-retry="${mongo.auto-connect-retry}" socket-timeout="${mongo.socket-timeout}" slave-ok="${mongo.slave-ok}" write-number="${mongo.write-number}" write-timeout="${mongo.write-timeout}" write-fsync="${mongo.write-fsync}" /> </mongo:mongo> <!-- <mongo:db-factory dbname="database" mongo-ref="mongoData" /> --> <!-- 用户信息配置 --> <!-- <bean id="userCredentials" class="org.springframework.data.authentication.UserCredentials"> <constructor-arg name="username" value="userName"/> <constructor-arg name="password" value="password"/> </bean> --> <bean id="testMongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"> <constructor-arg ref="mongoData" /> <constructor-arg name="databaseName" value="xiaomu_test" /> <!-- <constructor-arg ref="userCredentials" /> --> </bean> </beans>
3、mongo.properties文件：
#=============================================================== #mongo #=============================================================== mongo.ip=127.0.0.1 mongo.port=27017 mongo.connections-per-host=2 mongo.max-auto-connect-retry-time=15000L mongo.threads-allowed-to-block-for-connection-multiplier=4 mongo.connect-timeout=10000 mongo.max-wait-time=15000 mongo.auto-connect-retry=true mongo.socket-timeout=15000 mongo.slave-ok=true mongo.write-number=1 mongo.write-timeout=0 mongo.write-fsync=true
4、配置service和dao方法：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="mongoService" class="com.test.service.mongo.impl.MongoServiceImpl"> <property name="mongoDao" ref="mongoDao" /> </bean> <bean id="mongoDao" class="com.test.dao.mongo.impl.MongoDaoImpl"> <property name="testMongoTemplate" ref="testMongoTemplate" /> </bean> </beans>
java调用mongo：
注：所有的collectionName都可用bean的类名代替，表示操作一bean类名命名的collection，插入时直接传入一个bean默认会创建一个与bean同名的collection
增加：
//数据形式为： /* { "name" : "MongoDB", "type" : "database", "count" : 1, "info" : { x : 203, y : 102 } } */ BasicDBObject doc = new BasicDBObject("name", "MongoDB") .append("type", "database") .append("count", 1) .append("info", new BasicDBObject("x", 203).append("y", 102)); testMongoTemplate.insert(doc,"testColl"); //testMongoTemplate.insertAll(users); //users是list集合，批量插入
删除：
方式一： BasicDBObject query = new BasicDBObject("name", "MongoDB"); testMongoTemplate.remove(query, collectionName); 方式二： Criteria criteria = Criteria.where("age").gt(20);; //年龄大于20 //Criteria criteria = Criteria.where("id").is(20;//年龄等于20 Query query2 = new Query(criteria); testMongoTemplate.remove(query2, collectionName); 方式三（collection对象方法删除）： DBCollection coll = testMongoTemplate.getCollection(collectionName);//通过collection名称获取collection对象 coll.remove(query);
修改：
//普通修改 Criteria criteria = Criteria.where("id").is(123); Query query = new Query(criteria); Update update = Update.update("age", 23).set("name", "xiaomu"); testMongoTemplate.updateFirst(query, update, collectionName); //testMongoTemplate.updateMulti(query, update, collectionName);//修改多条数据 //根据条件查询出来后 再去修改 Criteria criteria = Criteria.where("id").is(123); Query query = new Query(criteria); Update update = Update.update("age",12).set("name", "xiaoli"); testMongoTemplate.findAndModify(query, update, collectionName.getClass());//查询出来后修改 //testMongoTemplate.findAndRemove(query, update, collectionName.getClass());//查询出来后删除
查询：
//1、查询一条数据（通过获取集合用集合删除方法删除） Set<String> names = testMongoTemplate.getCollectionNames();//获取collection的所有名称 DBCollection coll = testMongoTemplate.getCollection(collectionName);//通过collection名称获取collection对象 BasicDBObject query = new BasicDBObject("name", "MongoDB"); DBObject oneMessage = coll.findOne(query);//查询一条数据 //2、多条数据查询 //查询j不等于3，k大于10的结果 //BasicDBObject query = new BasicDBObject("j", new BasicDBObject("$ne", 3)) // .append("k", new BasicDBObject("$gt", 10)); //查询20 < i <= 30 的结果 //BasicDBObject query = new BasicDBObject("i", new BasicDBObject("$gt", 20).append("$lte", 30)); //多结果查询返回游标 DBCursor cursor = coll.find(query);//不传查询条件表示查询所有集合内容 try { while(cursor.hasNext()) { System.out.println(cursor.next()); } } finally { cursor.close(); } //查询集合中所有数据 List<? extends String> allResult = testMongoTemplate.findAll(collectionName.getClass());//查询所有 //正则匹配查询 Query query = new Query(); Criteria criteria = Criteria.where("name").regex("^" + "xiaoli"); query.addCriteria(criteria); testMongoTemplate.find(query, collectionName.getClass()); //分页查询 //分页 Criteria criteria = Criteria.where("age").gt(20);; //年龄大于20 Query query = new Query(criteria); query.skip(5); //skip跳过，表示分页的起始位置 query.limit(10); //每页显示的条数 testMongoTemplate.find(query, collectionName.getClass());
更过方法请参考api。
