使用spring-data-mongodb操作mongodb

mongodb.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:property-placeholder location="classpath*:mongodb.properties"  />

    <!--username="${mongo.username}"-->

    <!--password="${database.password}"-->

    <mongo:db-factory id="mongoDbFactory"

                      host="${mongo.host}"

                      port="${mongo.port}"

                      dbname="${mongo.dbname}"

    />

    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">

        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>

    </bean>

</beans>

mongodb.properties

mongo.host=127.0.0.1

mongo.port=27017

mongo.dbname=test

#mongo.username=

#database.password=

操作mongodb的测试方法

@Resource

MongoOperations mongoOperations;

@Test

public void testMongodb(){

    User user = new User();

    user.setName("testMongodb");

    user.setAge(12);

    mongoOperations.save(user, "collectionName");

    User userGetFromMdb = mongoOperations.findOne(new Query(Criteria.where("name").is("testMongodb")), User.class, "collectionName");

    System.out.println(userGetFromMdb);

}
