Spring 与 mongoDB 整合
首先需要引入jar包<dependency>
<groupId>org.mongodb</groupId>
<artifactId>mongodb-driver</artifactId>
<version>3.3.0</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
<version>1.9.4.RELEASE</version>
</dependency>
View Code spring中注入对象org.springframework.data.mongodb.core.MongoTemplate，该类中包含了mongoDB的增删改查
<!-- MongoDB -->
<mongo:mongo-client host="${mongo.host}"
port="${mongo.port}" credentials="${mongo.credentials}">
<mongo:client-options write-concern="NORMAL" />
</mongo:mongo-client>
<bean>
<constructor-arg ref="mongo-client" />
<constructor-arg name="databaseName" value="${mongo.databaseName}" />
</bean>
View Code 需要注意的是：
host：主机ip
port：端口号
credentials：连接mongoDB的一些参数，规则如：“username:password@Authentication”
如果用的是MongoChef可视化工具，对应如下所示的三个参数。
首先需要引入mongo对象，
@Autowired
private MongoOperations mongo;
删除操作
@Override
public void deleteQstByTpId(String tpId) {
mongo.remove(new Query(Criteria.where("test").is(tpId)),QuestionBean.class,COLLECTION_NAME);
}
View Code 增加操作
@Override
public void insertListZzQst(List<QuestionBean> list) {
mongo.insert(list,COLLECTION_NAME);
}
View Code 查找操作
@Override
public List<QuestionBean> findAllQstByTpId(String tpId) {
List<QuestionBean> list = mongo.find(new Query(Criteria.where("test").is(tpId)), QuestionBean.class,COLLECTION_NAME);
return list;
}
View Code 多条件查询
@Override
public List<QuestionBean> qrySomeQst(List<String> qryList,String testPaperId) {
return mongo.find(new Query(Criteria.where("test").is(testPaperId).andOperator(Criteria.where("type").in(qryList))), QuestionBean.class,COLLECTION_NAME);
}
