mongoDB数据库和Spring MVC的整合

之前一直用到的项目是Spring MVC+maven+mysql的，最近有些数据需要用到mongoDB数据库，现在做一些总结。

第一步：加载jar、maven配置

<!-- mongodb开始 -->
         <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongo-java-driver</artifactId>
            <version>3.3.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-mongodb</artifactId>
            <version>1.7.1.RELEASE</version>
        </dependency>
        <!-- mongodb结束 -->

第二步：配置

1、集群配置

applicationContext.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"
    xmlns:jee="http://www.springframework.org/schema/jee"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mongo="http://www.springframework.org/schema/data/mongo"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
        http://www.springframework.org/schema/jee
        http://www.springframework.org/schema/jee/spring-jee-4.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/schema/util
        http://www.springframework.org/schema/schema/util/spring-util-4.1.xsd
        http://www.springframework.org/schema/data/mongo
        http://www.springframework.org/schema/data/mongo/spring-mongo-1.5.xsd
        http://www.springframework.org/schema/data/repository
        http://www.springframework.org/schema/data/repository/spring-repository-1.5.xsd
        ">

   <mongo:mongo  id="mongo"  replica-set="${mongodb.replicaSet}" />
   <mongo:db-factory dbname="${mongodb.database}" mongo-ref="mongo"/> 

    <!-- mongo模板操作对象 -->
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory"/>
    </bean>

</beans>

配置文件common-config.properties

mongodb.database=cxstatistics
mongodb.replicaSet = 10.0.11.28:27017,10.0.11.29:27017,10.0.11.30:27017

2、单机配置

applicationContext.xml

<mongo:mongo id="mongo" host="${mongo.host}" port="${mongo.port}" >
        <mongo:options connections-per-host="${mongo.connectionsPerHost}"
            threads-allowed-to-block-for-connection-multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}"
            connect-timeout="${mongo.connectTimeout}" max-wait-time="${mongo.maxWaitTime}"
            auto-connect-retry="${mongo.autoConnectRetry}" socket-keep-alive="${mongo.socketKeepAlive}"
            socket-timeout="${mongo.socketTimeout}" slave-ok="${mongo.slaveOk}" write-number="1"
            write-timeout="0" write-fsync="true"/>
    </mongo:mongo>

配置文件common-config.properties

mongo.dbname = test_db #数据库名称
mongo.password = test_pwd #密码
mongo.username = test_user #用户名
mongo.host = 127.0.0.1 #主机
mongo.port= 27017 #端口号
mongo.connectionsPerHost= 8 #一个线程变为可用的最大阻塞数
mongo.threadsAllowedToBlockForConnectionMultiplier= 4 #线程队列数,它以上面connectionsPerHost值相乘的结果就是线程队列最大值
mongo.connectTimeout= 1500 #连接超时时间（毫秒）
mongo.maxWaitTime= 1500 #最大等待时间
mongo.autoConnectRetry= true #自动重连
mongo.socketKeepAlive= true #scoket保持活动
mongo.socketTimeout=1500 #scoket超时时间
mongo.slaveOk=true #读写分离

第三步、MongoDB的增删改查

1、Mongodb对象模型

Interview.java

@Document(collection="pagelog")
public class Interview implements Serializable {

    /**
     *
     */
    private static final long serialVersionUID = 1L;

    @Id
    private String id;

    private String time;
    private String desc;
    private long _createtime;
    private Integer _processed;
    private long fid;
    private String templateType;
    private long puid;

    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getTime() {
        return time;
    }
    public void setTime(String time) {
        this.time = time;
    }
    public String getDesc() {
        return desc;
    }
    public void setDesc(String desc) {
        this.desc = desc;
    }
    public long get_createtime() {
        return _createtime;
    }
    public void set_createtime(long _createtime) {
        this._createtime = _createtime;
    }
    public Integer get_processed() {
        return _processed;
    }
    public void set_processed(Integer _processed) {
        this._processed = _processed;
    }
    public long getFid() {
        return fid;
    }
    public void setFid(long fid) {
        this.fid = fid;
    }
    public String getTemplateType() {
        return templateType;
    }
    public void setTemplateType(String templateType) {
        this.templateType = templateType;
    }
    public long getPuid() {
        return puid;
    }
    public void setPuid(long puid) {
        this.puid = puid;
    }

}

Pagecount.java

@Document(collection="countlog")
public class Pagecount implements Serializable{

    /**
     *
     */
    private static final long serialVersionUID = 1L;

    @Id
    private String id;

    private String time;
    //private long  fid;
    List<Integer> fid = new ArrayList<Integer>();
    //private Integer pagenum;
    List<Integer> pagenum = new ArrayList<Integer>();

    public String getTime() {
        return time;
    }
    public void setTime(String time) {
        this.time = time;
    }
    public List<Integer> getFid() {
        return fid;
    }
    public void setFid(List<Integer> fid) {
        this.fid = fid;
    }
    public List<Integer> getPagenum() {
        return pagenum;
    }
    public void setPagenum(List<Integer> pagenum) {
        this.pagenum = pagenum;
    }

}

2、查询示例代码

接口：

/**
     * 得到时间区间内的统计数据
     * @param beginDate
     * @param endDate
     * @return
     */
    public long getInterviewNum(String beginDate, String endDate);

/**
     * 得到时间区间内根据fid排序的统计数据list
     * @param beginDate
     * @return
     */
    public List<Pagecount> getPageGroup(String beginDate);

接口实现：

@Override
    @Path("getInterviewNum")
    @GET
    @Produces({"application/json; charset=UTF-8"})
    public long getInterviewNum(@QueryParam("beginDate")String beginDate, @QueryParam("endDate")String endDate) {
        long Num=mongo.count(new Query(Criteria.where("time").gt(beginDate).lte(endDate)), Interview.class);
        return Num;
    }

@Override
    @Path("getPageGroup")
    @GET
    @Produces({"application/json; charset=UTF-8"})
    public List<Pagecount> getPageGroup(@QueryParam("beginDate")String beginDate) {
        Criteria criatira= new Criteria();
        criatira.andOperator(Criteria.where("time").is(beginDate));
        List<Pagecount> pagecount = new ArrayList<Pagecount>();
        String year= beginDate.substring(0,4);
        String month=beginDate.substring(5);
        mongo.getDb().eval("pagelog("+year+","+month+")");
        //mongo.getDb().eval("pagelog("+beginDate+")", pagecount);
        pagecount= mongo.find(new Query(criatira).with(new Sort(new Order(Direction.DESC, "pagenum"))), Pagecount.class);
        return pagecount;
    }
    

控制层：

@Path("")
public class InterviewController {

    @Autowired
    StatisticsService statisticsService;

    @Post("/interview")
    @Get("/interview")
    @AdminLoginRequired
    public String index(Invocation inv) {
        Calendar c = Calendar.getInstance();
        c.add(Calendar.MONTH, -1);
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
        String mDateTime=formatter.format(c.getTime());
        inv.addModel("dateTime", new SimpleDateFormat("yyyy-MM-dd").format(new Date()));
        inv.addModel("mDateTime", mDateTime);
        return "/views/statistics/interview.vm";
    }

    @Post("/getInterview")
    @Get("/getInterview")
    public String getInterview(Invocation inv,@Param("beginDate")String beginDate,@Param("endDate")String endDate){
        long Num = statisticsService.getInterviewNum(beginDate, endDate);
        inv.addModel("Num", Num);
        JSONObject json = new JSONObject();
        json.put("Num", Num);
        return "@"+json;
    }

    @Post("/interviewGroup")
    @Get("/interviewGroup")
    @AdminLoginRequired
    public String indexGroup(Invocation inv) {
        Calendar c = Calendar.getInstance();
        c.add(Calendar.MONTH, -1);
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM");
        String mDateTime=formatter.format(c.getTime());
        inv.addModel("mDateTime", mDateTime);
        return "/views/statistics/interviewGroup.vm";
    }

    @Post("/getPageGroup")
    @Get("/getPageGroup")
    public String getPageGroup(Invocation inv,@Param("beginDate")String beginDate){
         List<Pagecount> Pagecount = new ArrayList<Pagecount>();
         Pagecount = statisticsService.getPageGroup(beginDate);
         JSONObject json = new JSONObject();
         json.put("list", Pagecount);
         return "@"+json;
       }
}

3、mongoDB存储过程：

function(year,month){
var time=year+'-'+month;
if(month<10){
   time=year+'-0'+month;
 }
var num=[];
var fid=[];
db.getCollection('pagelog').aggregate([ { $match : {'time':{$regex: "^" + time + ".*$"}} },{$group : { _id : "$fid", num : {$sum : 1}}}]).forEach(function(obj){
            num.push(obj.num);
            fid.push(obj._id);
 })
document1=num;
document2=fid;
 db.countlog.update({'time':time},{$set:{'fid':document2,'pagenum':document1,'time':time}},true,true);
return time;
}
