我的第一个Spring MVC与Mongo;mongoscocketception

Question

嗨，我正在使用带有Spring MVC的MongoDB。我面临以下问题-"HTTP状态500-处理程序处理失败；嵌套异常为java.lang.NoClassDefFoundError:mongodb/MongoSocketException"。

以下是我的项目详细信息。

WEB.XML是：

</servlet>
<servlet-mapping>
    <servlet-name>SpringMVCMongo</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Dispatcher-servlet.xml is:

Answer 1

您应该至少将mongo-java-driver版本升级到2.12.0。这是引入MongoSocketException的第一个版本(对前一个版本的未检查异常替换(。

spring-data-mongodb版本1.5.2.RELEASE是用mongo-java-driver版本2.12.1编译的，它比您在pom中声明的版本(2.11.0("旧"。

您应该将其设置为mongo-java-driver的固定依赖版本。意味着将mongo-java-driver从2.11.0更改为2.12.1

Answer 2

A发现您的web.xml和Dispatcher-servlet.xml，

在Spring中，servlet名称必须与调度器名称相同，即您应该将Dispatcher-servlet.xml重命名为SpringMVCMongo-servlet.xml。

然后试试代码。

一切都好。
