spring常见问题

1.引用错误

2018-12-29 17:20:52 ERROR [RMI TCP Connection(3)-127.0.0.1] [org.springframework.web.context.ContextLoader]     - Context initialization failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [D:\out\artifacts\demo\WEB-INF\classes\demo\controller\DemoController.class]; nested exception is java.lang.ArrayIndexOutOfBoundsException: 52264

问题原因：spring3.1不支持java8语法，比如：list.stream操作改成for循环即可
