错误原因: 没有发现Mybatis配置文件的路径 解决方法: 检查Mapper包名与xml文件标签的namespace数据名称是否相同 <mapper namespace="com.tuyrk._161_java_socket.project6.dao.FileMapper"></mapper> Mapper中定义的方法未在xml文件中配置 Mapper中方法返回值是List ,而select元素没有正确配置resultMap标签,或者只配置resultType

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!

解决方案参考:https://blog.csdn.net/hhj13978064496/article/details/82825365 我将eureka的依赖包放到了依赖包的最下面,启动报错, 如下: <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId&

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

一.问题由来 本地代码在一次打包后,再次启动项目时报了一个错误,详细的错误信息如下: 2020-10-23 15:10:26.724 [] [main] INFO o.s.c.a.AnnotationConfigApplicationContext[583] - Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@79d94571: startup date [Fri Oct 2

今天搭建了一个SpringBoot项目,刚启动就报错 Disconnected from the target VM, address: '127.0.0.1:2227', transport: 'socket' 百度一下,有人说端口占用,有人说Mavenban不兼容,我测试一下以前的项目可以正常运行,断定不是这些问题!仔细检查,原来是pom.xml文件出了问题! 如图: 修改之后: 正常启动!

一.问题 springboot项目启动时报错: Field userMapper in com.example.springbootdruid.service.impl.UserServiceImpl required a bean of type 'com.example.springbootdruid.mapper.UserMapper' that could not be found. 原因是因为没有扫描到对应的类 二.解决方式: 1.检查配置文件是否写对: 在springboot的配置文

新建了一个springboot项目报一下错误: Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. Reason: Failed to determine a suitable driver class 原因是加入了mybatis依赖而没有指定数据库url属性,解决方式: 1.去除mybatis依赖,即去除 <depen
