项目jdk/jar包冲突分析处理过程

今天从Git上拉了一个老项目到本地运行，一直报错不停，运行不成功。

Context initialization failed

经过查阅资料可能有是jdk版本过高原因，果断将jdk8、jdk7、jdk6都试了一次，果然在jdk6时运行报错有所不同之处。 
以下为第一次报错信息：

Controller控制器时报错

然后将所有java代码进行了移出和注释操作，发现空项目是可以运行成功的，但只要一创建Controller时就会报以下错误。 
此时jdk版本为7.0，报错内容如下：

替换spring版本

经过查看发现spring版本为3.2,网上说jdk7以上兼容的spring版本为4.0。 
但我想jdk6兼容spring3.2应该没问题，但运行还是不成功。只能替换spring 4.0版本上去了。 
换spring版本之后报错如下：

发现有时候java的异常错误并不能直接反映问题所在，这点没有php错误异常明白样。

替换jar包不彻底

经过点击报错代码 org.springframework.web.servlet.HttpServletBean.init(HttpServletBean.java:138) 发现spring-web.jar包的版本还是3.2,没有替换掉所致。 
替换运行以后正常。

总结

1、切换不同的jdk版本进行项目运行，查看报错内容，以确定是否为jdk版本问题导致。 
2、关注jar包版本，是否与当前jdk版本兼容 
3、仔细分析异常日志内容
