Spring mvc 4.2.5 在为 mongodb 配置 spring 数据后显示没有类防御发现异常

标签 spring mongodb spring-mvc spring-data

我是使用 mongo DB 的 Spring MVC 新手。我之前使用传统数据库(Postgresql-JDBC 模板)创建了 Spring MVC 应用程序。自 1 周以来，我在配置 MongoDB bean 后在我的项目中遇到了问题。

我创建了一个工作正常的 spring MVC 应用程序。现在我需要将我的数据保存到 MongoDB(MongoDB shell 版本:3.2.9)，

所以我下载了相关的jar，所以请检查我的依赖版本(我试过maven但也显示错误)。

 mongodb-version - 3.2.9
 Spring mvc version - 4.2.5.RELEASE
 mongo-java-driver  - 3.4.1
 spring-data-commons -2.0.0.M1
 spring-data-mongodb -2.0.0.M1
 slf4j-log4j12-1.7.22.jar
 log4j-slf4j-impl-2.0.jar
 Tomcat v8.0 Server at localhost
 java 8
 Dynamic Web Module 3.1

IDE - Eclipse 火星

我将所有 jar 保存在 WEB-INF/lib 文件夹中 在这里我想给我的spring-dispatcher-servlet

我发现了很多与此相关的问题，但每个人都使用不同版本的 spring，大多数使用 Spring 3.x 版本。

我试过 3.x 版本，但我再次发现 jar 版本问题。我尝试了 maven，但当时我的项目中发生了 servlet 生命周期异常。我想使用 spring MVC 4.2.5 因为我之前完成了一个以 psql 作为 DB 和 SpringJdbcTemplate 作为依赖项的项目。如果我得到 Spring 4.2.5 版本的解决方案，我会更高兴。

我还想了解 LoggerFactory 及其在 MongoDB spring 项目中的需求。如果有人遇到问题，请告诉我。提前致谢

最佳答案

我以前遇到过同样的问题，请你试试这些maven依赖项好吗
