spring在集成第三方过程很容易出现类名相同,且基本作用相同的类.这样给初学者带来一定的困惑. 导致用错类而出现以下问题. required a bean of type 'com.netflix.discovery.DiscoveryClient' that could not be found. 此问题就是我们错误的使用了netflix的DiscoveryClient,而非spring的. 解决方案: 换成spring的类,好啰嗦呀. 详细 https://stackoverflow.co…

最近项目里面,用了spring的定时任务,一直以来,项目运行的不错.定时器也能正常使用.可是,今天启动项目测试的时候,盯着启动Log看了一阵子,突然间发现,启动的Log中居然有一个异常,虽然一闪而过,但是那熟悉的异常格式还是让我浑身一颤.这个项目一直运行的很好啊,没发现有什么问题,怎么会出现异常呢? 于是我仔细的翻啊翻啊,查啊找啊,嘿,还真的找到了两个异常: [2016-10-12 22:49:10,184] [DEBUG] (ScheduledAnnotationBeanPostProcess…

先写了JUnit,发现启动不了,注释掉有问题的service也不可以.可能是因为spring开始时会加载所有service吧. 按照网友们的说法,一般需要检查: 1.入口类有没有写MapperScan 我写了,没问题:) @MapperScan(basePackages="com.example.demo.mapper") 2.该service对应的dao接口上没写@Mapper 我写了,没问题:) 3.@Service里的字符串与该service名称不一致 由于我这个service是…

SpringBoot项目的Bean装配默认规则是根据Application类所在的包位置从上往下扫描! “Application类”是指SpringBoot项目入口类.这个类的位置很关键: 如果Application类所在的包为:com.boot.app,则只会扫描com.boot.app包及其所有子包,如果service或dao所在包不在com.boot.app及其子包下,则不会被扫描! 即, 把Application类放到dao.service所在包的上级,com.boot.Applicat…
