springframework 升级的几个坑
从2版本升到5.1.6版本
xml配置文件中必须有
<context:component-scan base-package="cn.itcast.dubbodemo"></context:component-scan>
配置文件中必须有context相关的schema
xmlns:context="http://www.springframework.org/schema/context"
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd

否则会报
No ConfigurableListableBeanFactory set

时区问题参加之前的文章

对实体 "characterEncoding" 的引用必须以 ';' 分隔符结尾
因为这里使用的xml文件,需要将&替换为 &

org.springframework.web.util.Log4jConfigListener

新版已经没有了，删除对应的web.xml描述

aspectj版本问题

ClassFormatException: Invalid byte tag in constant pool: 18

既然知道病因了就该对症下药，我特意看了一下我的pom文件，aspectj weaver这个包我引用的是1.6版，我去Maven中央仓库看了一下，我了个乖乖，都更新到1.9X了，果然是版本太老了。于是修改pom.xml将aspectj weaver的版本1.6.8改为1.9.2。
