在java中使用CouchDb4J API时，临时视图不起作用

我尝试使用上面的代码创建临时视图，我得到

import com.fourspaces.couchdb.Session;
import com.fourspaces.couchdb.Database;
import com.fourspaces.couchdb.Document;
import com.fourspaces.couchdb.View;
import com.fourspaces.couchdb.ViewResults;
import com.fourspaces.couchdb.CouchResponse;
import com.fourspaces.couchdb.AdHocView;

public class temporaryViews 
{
public static void main(String[] args) throws Exception 
{

    Session s = new Session("localhost",5984,"monil","monil",false,false);
    Database db = s.getDatabase("foodb");

// Running a view
       ViewResults resultAdHoc = db.adhoc("function (doc) {emit(null, doc);}");
       System.out.println(resultAdHoc.getResults().size());
  }
}

请提出解决办法

import com.fourspaces.couchdb.Session;
import com.fourspaces.couchdb.Database;
import com.fourspaces.couchdb.Document;
import com.fourspaces.couchdb.View;
import com.fourspaces.couchdb.ViewResults;
import com.fourspaces.couchdb.CouchResponse;
import com.fourspaces.couchdb.AdHocView;

public class temporaryViews 
{
public static void main(String[] args) throws Exception 
{

    Session s = new Session("localhost",5984,"monil","monil",false,false);
    Database db = s.getDatabase("foodb");

// Running a view
       ViewResults resultAdHoc = db.adhoc("function (doc) {emit(null, doc);}");
       System.out.println(resultAdHoc.getResults().size());
  }
}

提前谢谢

我也遇到了同样的问题。试试看，这会对你有所帮助。

我在这里面临同样的问题（无法创建视图）。临时解决方法是更新服务器配置。在

coach.ini

文件中修改身份验证\u处理程序：

import com.fourspaces.couchdb.Session;
import com.fourspaces.couchdb.Database;
import com.fourspaces.couchdb.Document;
import com.fourspaces.couchdb.View;
import com.fourspaces.couchdb.ViewResults;
import com.fourspaces.couchdb.CouchResponse;
import com.fourspaces.couchdb.AdHocView;

public class temporaryViews 
{
public static void main(String[] args) throws Exception 
{

    Session s = new Session("localhost",5984,"monil","monil",false,false);
    Database db = s.getDatabase("foodb");

// Running a view
       ViewResults resultAdHoc = db.adhoc("function (doc) {emit(null, doc);}");
       System.out.println(resultAdHoc.getResults().size());
  }
}

Exception in thread "main" java.lang.NullPointerException
at temporaryViews.main(temporaryViews.java:53)

重要的一个是null\u身份验证\u处理程序，但请注意：正如所述，这是为了开发目的

import com.fourspaces.couchdb.Session;
import com.fourspaces.couchdb.Database;
import com.fourspaces.couchdb.Document;
import com.fourspaces.couchdb.View;
import com.fourspaces.couchdb.ViewResults;
import com.fourspaces.couchdb.CouchResponse;
import com.fourspaces.couchdb.AdHocView;

public class temporaryViews 
{
public static void main(String[] args) throws Exception 
{

    Session s = new Session("localhost",5984,"monil","monil",false,false);
    Database db = s.getDatabase("foodb");

// Running a view
       ViewResults resultAdHoc = db.adhoc("function (doc) {emit(null, doc);}");
       System.out.println(resultAdHoc.getResults().size());
  }
}

希望有人能找到一个真正的解决方案（用于生产环境）。

我需要使用Couchdb4j api创建视图，有人能给我推荐解决方案吗

import com.fourspaces.couchdb.Session;
import com.fourspaces.couchdb.Database;
import com.fourspaces.couchdb.Document;
import com.fourspaces.couchdb.View;
import com.fourspaces.couchdb.ViewResults;
import com.fourspaces.couchdb.CouchResponse;
import com.fourspaces.couchdb.AdHocView;

public class temporaryViews 
{
public static void main(String[] args) throws Exception 
{

    Session s = new Session("localhost",5984,"monil","monil",false,false);
    Database db = s.getDatabase("foodb");

// Running a view
       ViewResults resultAdHoc = db.adhoc("function (doc) {emit(null, doc);}");
       System.out.println(resultAdHoc.getResults().size());
  }
}
