SpringData 和 MongoDB 配置错误：MongoTemplate

Question

我目前正在尝试将 mongodb 集成到我的 Spring 应用程序中。

我已经在我的机器上设置了初始的 mongodb 环境，服务启动等

但是在 spring 的应用程序配置中存在与 mongoTemplate construction-arg 相关的错误

“通配符是严格的，但没有找到元素的声明”

我实际上使用了与文档here 中描述的相同的 xml 支出，与最近的一些在线教程相同，据我所知，我已经添加了正确的命名空间 url。所以我现在有点迷失了我所缺少的东西。非常感谢您对此提供任何帮助。

这里看一下xml配置：

<?xml version="1.0" encoding="UTF-8"?>

限定 xsd 名称以匹配您正在使用的 spring 版本。

考虑到您使用的是 Spring 4，xshema 命名空间将更改为以下。

<beans:beans xmlns="http://www.springframework.org/schema/mvc"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns:beans="http://www.springframework.org/schema/beans"
         xmlns:context="http://www.springframework.org/schema/context"
         xmlns:mongo="http://www.springframework.org/schema/data/mongo"
         xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
    http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.7.xsd">
