一.背景 springboot的出现,让项目搭建变得更方便快捷,同时简化掉很多的样板化配置代码,提高开发效率. 通过idea生成springboot项目,启动报错:Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. 通过错误不难看出是因为dataSource的url配置缺失导致,但是新生成的项目并没有使用到jdbc,为什…

SpringBoot1.5,项目启动报错: Could not resolve placeholder 很明显是找不到配置文件引起的,查看配置文件目录结构如下: 很正常呀. 完全可以加载application-dev.properties配置文件呀 检查IDEA的启动工作目录,我靠,原来是默认是整个工程的根目录,而不是application这个启动java文件的model下,修改,搞定!…

最近在用springboot构建项目,控制台报错:Handler dispatch failed; nested exception is java.lang.AbstractMethodError,看了下代码编译,bean依赖,jar包版本,网上找了好多资料,依然没发现问题. 最后终于解决. 原因:由于target 文件夹之前生成了 jar包,新启动时springBoot内置Tomcat加载时存有之前的代码缓存,导致 jar包冲突. 解决方案:删掉 target  下边所有的子文件夹,文件.…

描述: 我们在启动spring-boot,spring-cloud 项目时,是不是经常 遇到报错,但是在控制台 没有能找到 具体 报错信息,只是 提示,启动失败,缺乏具体的报错信息,这样就很不方便我们去找到 报错 原因!也就不能 方便解决问题. 解决小 技巧 我们在 springboot 应用的程序入口main 方法中 加入 try catch 代码,这样,在启动中如果报错了,就可以 直接捕获到异常,然后我们打印到控制台,这样就能很快定位并解决问题了! 示例代码如下: public static…

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…
