Spring Mongodb连接 [英] Spring Mongodb Connectivity

问题描述

我的Conf.xml文件包含

 <? xml version = "  encoding = "  <   beans     ="   http://www.springframework.org/schema/beans" 
 
    xmlns:xsi   ="  http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:cloud   ="  http://schema.cloudfoundry.org/spring" 
    xmlns:jdbc   ="  http://www.springframework.org/schema/jdbc" 
    xmlns:util   ="  http://www.springframework.org/schema/util" 
    xmlns:mongo   ="  http://www.springframework.org/schema/data/mongo" 
    xsi:schemaLocation   ="  http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd

<   bean        mongoDbFactory"  class    org.springframework.data.mongodb.core.SimpleMongoDbFactory" <   constructor-arg     ref   ="  >

<   constructor-arg    名称  ="  值   27017 " 类型   int" > 
<  /bean  > 

<  /beans  >   

我得到的错误如下

无法加载应用程序上下文

原因:org.springframework.beans.factory.BeanCreationException:在类路径资源[mongo-conf.xml]中创建名称为'mongoTemplate'的bean时出错.嵌套的异常是org.springframework.beans.BeanInstantiationException:无法实例化bean类[org.springframework.data.mongodb.core.MongoTemplate]:构造函数抛出了异常；嵌套异常是java.lang.IllegalAccessError:尝试访问方法org.springframework.core.GenericTypeResolver.getTypeVariableMap(Ljava/lang/Class;)Ljava/util/Map;来自类org.springframework.data.util.ClassTypeInformation 

解决方案

Quelle Surprise-您的配置文件"mongo-conf.xml"不正确.但是我想你已经想通了.

您是否真的提供了一个名为"mydb"的数据库?它可以在本地主机上使用吗?您能解决它(ping左右)吗?

我也有同样的问题.您对这个问题有任何解决办法吗?

我已经在春季论坛上发布了类似的问题.

And the Error which is I am getting is as follows

Failed to load application context

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongoTemplate' defined in class path resource [mongo-conf.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.data.mongodb.core.MongoTemplate]: Constructor threw exception; nested exception is java.lang.IllegalAccessError: tried to access method org.springframework.core.GenericTypeResolver.getTypeVariableMap(Ljava/lang/Class;)Ljava/util/Map; from class org.springframework.data.util.ClassTypeInformation

解决方案

Quelle Surprise - your config file "mongo-conf.xml" is not ok. But I guess you already figured that.

Do you really provide a DB called "mydb" ?? is it available at localhost? can you address it (ping or so)?

i have the same problem. Did you get any resolution to this problem ?

I have posted a similar question on spring forums.
