错误提示，如下

 

log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.

Test.java.18语句：ClassPathXmlApplicationContext cpx=new ClassPathXmlApplicationContext("applicationContext.xml");

解决办法：起初我以为是xml中配置有错误，后来仔细检查整个程序代码，发现原来有一处的dataSource被写成了dateSource。

刚刚搞spring。property注入时遇到这个问题，百度一下。非常多人说是命名或者get set方法不一致的问题，可是这个我是知道的。写的时候也注意到这些。所以应该不是这个问题。以为是xml头写的问题。可是换了几个都不行。后来灵机一动。会不会是变量设置成静态的原因。试着把静态去了。一搞。ok了。 总结。get方法是不能静态的，变量和set是能够的。 ...
