我正在使用Java将数据插入到mongodb集群中.我可以拥有超过1个mongos实例,以便在我的一个mongos关闭时有备份吗？

这是我连接到mongos的java代码.

MongoClient mongoClient = new MongoClient("10.4.0.121",6001);
DB db = mongoClient.getDB("qbClientDB");
DBCollection collection = db.getCollection("clientInfo");

如何在Java代码中指定我的第二个mongos实例？(如果可能的话).

提前致谢.

我有一个弹性搜索索引,用户的字段如..."name":"kai""age":"23""location":"Delhi,India""tag":["search","nosql"]等.

我想在用户的所有字段中查询多个字符串(例如.["nosql","delhi"]).是否可以使用Java API？

这是我正在使用的代码示例.(但这与问题无关)它只是为了知道我现在正在使用的对象.

BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery()
                .must(QueryBuilders.matchAllQuery());
        if(location!=null) {
            queryBuilder.must(QueryBuilders.matchQuery("location",location));
        }
        BoolFilterBuilder filerBuilder=FilterBuilders.boolFilter();     
        for(String skill:skills){
            filerBuilder.must(FilterBuilders.rangeFilter("tags."+skill).from(0));
        }
        filerBuilder.must(FilterBuilders.queryFilter(queryBuilder));
        if(age!=null) {
            filerBuilder.must(FilterBuilders.rangeFilter("age").from(age[0]).to(age[1]));
        }
        SearchResponse response = client.prepareSearch("skillbin")
                .setTypes("stackdump")
                .setSearchType(SearchType.QUERY_AND_FETCH)
                .setQuery(queryBuilder)   
                .setPostFilter(filerBuilder)
                .addSort("reputation", SortOrder.DESC)
                .execute()
                .actionGet();
        SearchHits hits=response.getHits(); 

提前致谢.:)

我正在使用Selenium 2.x WebDriver来实现java项目的自动化.当自动化进行时,它到达一个页面,当点击提交按钮时,出现"弹出窗口"并且不能进行自动化.

码

public void writeSite(WebDriver driver, ZoneTest zone) throws BiffException, InterruptedException, IOException

    //Creates a new zone for testing

    General.elementClick_xpath(driver, Locators.siteMenuDropBoxXpath);
    General.waitToLoad(General.WAIT_MIN);
    General.elementClick_xpath(driver, Locators.viewSitesButtonXpath);
    General.elementClick_xpath(driver, Locators.viewDataPointDetailsXpath);
    General.waitToLoad(General.WAIT_AVG);

    General.elementClick_xpath(driver, Locators.addZoneXpath);

    General.waitToLoad(General.WAIT_AVG);

    General.inputTextFieldEnter_Id(driver, "name", zone.zoneName);

    General.inputTextFieldEnter_Id(driver, "timeSpentThreshold", zone.thresholdTime);

我正在尝试使用Spring Social Facebook检索朋友的用户名.列出friends = facebook.friendOperations().getFriendProfiles(); 这句话给了我400 Bad Request错误.

@Controller
@RequestMapping("/")
public class HelloController {

    private Facebook facebook;

    @Inject
    public HelloController(Facebook facebook) {
        this.facebook = facebook;
    }

    @RequestMapping(method=RequestMethod.GET)
    public String helloFacebook(Model model) {
        if (!facebook.isAuthorized()) {
            return "redirect:/connect/facebook";
        }

        model.addAttribute(facebook.userOperations().getUserProfile());
        System.out.println(facebook.userOperations().getUserProfile().getName());
        System.out.println(facebook.userOperations().getUserProfile().getEmail());
        //PagedList<FacebookProfile> fbFrnds = facebook.friendOperations().getFriendProfiles();
        List<String> friendIds = facebook.friendOperations().getFriendIds();
        System.out.println("Id size : "+friendIds.size());
        List<FacebookProfile> friends = facebook.friendOperations().getFriendProfiles();
        System.out.println("Size : "+friends.size());
        for (FacebookProfile id : friends) {
            System.out.println(id.getName());
        }
        return "hello";
    }

}

错误如下所示.
