这里提示了问题所在：Invalid bean definition with name 'dataSource' defined in file [D:\tomcat\webapps\b2b2c_v60\WEB-INF\classes\applicationContext.xml]: Could not resolve placeholder 'removeAbandonedTimeout' in string value "${removeAbandonedTimeout}"

applicationContext.xml文件中的DataSource bean类是生成出了问题，因为removeAbandonedTimeout 这个无法被解析，你看一下你的属性配置文件中removeAbandonedTimeout是否配置正确，可能单词写错了，可能是忘了配置这项。

用编程的语言和你说就是，${removeAbandonedTimeout}这个的意思就是引用removeAbandonedTimeout 这个变量，你必须要在其他地方配置了这个变量才能被引用，否则就会报错
