分析思路 This web container has not yet been started
应用反馈更新应用后，出现页面加载不出信息的问题

分析思路：
1.根据日志第一层信息：
This web container has not yet been started 是 容器没有加载，初步这个看不出什么信息
2.接着堆栈信息最表层往下看：
com.apusic.aas.web.loader.WebappClassLoader.loadClass 这一段没什么用，主要是底层异常触发了，导致抛出This web container has not yet been started
3.接着看到：
at org.springframework.data.mongodb.core.MongoExceptionTranslator.translateExceptionIfPossible(MongoExceptionTranslator.java:112)
at org.springframework.data.mongodb.core.MongoTemplate.potentiallyConvertRuntimeException(MongoTemplate.java:2592)
at org.springframework.data.mongodb.core.MongoTemplate.execute(MongoTemplate.java:526)
这里注意看到有mongodb，不要看到spring相关就忽视了
4.接着通过https://nowjava.com/jar/ 输入 org.springframework.data.mongodb.core.MongoExceptionTranslator 或 org.springframework.data.mongodb.core.MongoTemplate
找到并下载相应jar包，通过JD-GUI反编译分析
可以确定是spring-data-mongodb的jar包，但版本也要注意下，因为是通过类路径找的jar，日志堆栈信息中具体到了方法，所以要找到有对应方法名的jar包版本(translateExceptionIfPossible、potentiallyConvertRuntimeException、execute)
（最好找应用确定他们用的是什么版本，这样比较好找，这里我以为：spring-data-mongodb-2.1.1.RELEASE.jar）
5.通过IDEA或JD-GUI反编译jar包：
5.1 在jar中找到步骤3中的相关方法，可以看到execute的try中为异常导致代码，基本可以确定是mongodb的问题，
catch中potentiallyConvertRuntimeException是抛出的异常，是一个异常方法，调用了MongoExceptionTranslator异常类的translateExceptionIfPossible，不是最表层的异常，
如果需要分析为什么mongodb会抛出到This web container has not yet been started，而不是明显的mongodb的异常，就可以用arthas工具对potentiallyConvertRuntimeException或translateExceptionIfPossible方法监控，从而监控定位最表层的mongodb异常，因为从 translateExceptionIfPossible到com.apusic.aas.web.loader.WebongappClassLoader.loadClass 中间还会有其他相关具体mongodb信息，可以通过监控找到具体原因
