从异常提示看，是缺少spring-web依赖，其实不然，我反复检查了工程中是有spring-web包的。

于是只能从源头查，查看方法com.xx.platform.cipher.machine.configurer.CipherWebConfig.messageConverters：

@Bean
public HttpMessageConverters messageConverters() {
    return new HttpMessageConverters(new FastJsonHttpMessageConverter());
}

这里方法很简单，就用到了spring-boot-autoconfigure和alibaba的fastjson，继续检查依赖，发现工程下没有fastjson，但是在tomcat的lib下有呀，不明白？

没辙了，于是猜想可能跟springboot的初始化有关系，运行时的依赖可以从工程的lib->tomcat的lib下依次寻找，但是springboot初始化需要的依赖只能从工程的lib寻找

既然假设了，就行动起来，添加fastjson之后居然问题解决了！

猜想可能不对，这里记录一下问题，持续关注！
