maven项目使用mongo-java-driver的一些错误

最近做一个比较老的java项目，然后遇到各种问题。其中一个是在使用maven管理mongo时，由于我使用的mongo-java-driver是2.11.2版本的，然后再发布的时候，老是报下面的错误java.lang.NoClassDefFoundError: org/bson/conversions/Bson

然后上网查了下，有些回答说直接拷贝mongo-java-driver3.x版本的jar包到WEB-INF的lib目录下，但是我用的是maven来管理的jar包，所以不能直接拷贝，然后通过修改pom.xml文件中将原来mongo-java-driver 的版本改成如下
            org.mongodb
            mongo-java-driver
            3.2.2
        

但是又遇到新的问题，由于我原来的旧项目用到authenticate requestDone requestStart等方法，但是在mongo-java-driver3.x中这些方法已经没有了，所以最终我把项目这些方法全部屏蔽后，终于解决了。
