Couchbase with Spring data using spring config example -

-

i newbie couchbase. using spring in application through trying connect couchbase in local. trying create couchbase template(similar done in mongo template) in configurations below:

spring configuration

repository using couchbase template

but when start application, autowiring errors , unable fetch anything. can please above issue? or if can share sample code extract data couchbase using sprin-data & spring configuration? please help!

so using spring data couchbase 1.4? framework offers dedicated namespace spring xml configuration should use instead of attempting call constructors:

xml configuration

<?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:couchbase="http://www.springframework.org/schema/data/couchbase"    xmlns:context="http://www.springframework.org/schema/context"    xsi:schemalocation="http://www.springframework.org/schema/data/couchbase http://www.springframework.org/schema/data/couchbase/spring-couchbase.xsd                        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd                        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">      <couchbase:couchbase host="127.0.0.1,192.168.1.101" bucket="default" password=""/>      <couchbase:template/> <!-- use default client above, no additional tuning--> </beans>

first notice xmlns:couchbase , couchbase-specific xsi:schemalocation in root.

secondly, not providing ids wire beans default ids (and same references, eg. default template reference default client if no "client-ref" attribute specified).

thirdly, notice format "host" parameter string, hostnames or ips separated commas (in case want bootstrap cluster).

at point template should available autowiring.

repository

for crud operations, spring data couchbase comes crudrepository abstraction. need to:

  • declare interface usersrepository extending crudrepository<users, string> (string being type of users field identifying it). let's it's in package com.test.repo.
  • enable building of repositories framework in xml config: <repositories base-package="com.test.repo" /> (click relevant section of doc)
  • autowire repository: @autowired public usersrepository repo;

the documentation has many more details concepts repositories, pre-requisites crud repository work in couchbase (short story: need create view up), how model , annotate entities, etc...

please have @ it, @ http://docs.spring.io/spring-data/couchbase/docs/1.4.0.release/reference/html/

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
