SpringData and MongoDB configuration error : MongoTemplate

Question

我目前正在尝试将 mongodb 集成到我的 spring 应用程序中。

我的机器上有初始 mongodb 环境设置、服务启动等

但是 spring 中的应用程序配置存在与 mongoTemplate 构造参数相关的错误

"wildcard is strict but no declaration found for element"

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网址。所以我现在对我所缺少的东西有点迷茫。非常感谢对此的任何帮助。

下面是 xml 配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </beans:bean>

限定 xsd 名称以匹配您正在使用的 spring 版本。

考虑到您正在使用 Spring 4，xshema 名称 space 将更改为以下内容。

<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
