Mybatis与springboot项目，启动时报错，详细的错误如下：

Field xxx in com.xxxl required a bean of type ‘xxx’ that could not be found.
Action:
Consider defining a bean of type ‘xxx’ in your configuration.

原因是bean装配失败，springboot扫描时没有找到DAO 的@Mapper对应的接口。
解决方法：
在启动类前加上：

@MapperScan(basePackages = { "mapper所在的包路径" }）

扫描xx.xx.mapper包下的所有mapper

确定要放弃本次机会？

【异常】spring.factories机制解决外部配置文件无法被读取提示Field XXX in XXX that could not be found的问题

Springboot约定俗成，在自动扫描包时，只会扫描自己模块下的类，但SpringCloud项目中，常会在子模块（mall-common）中创建公共方法，那么在另外一个子模块 (thirdparty-api)中，往往需要加载定义在子模块（mall-common）中指定的配置文件，从而实现相应的功能。如果想要被Spring容器管理的Bean的路径不再Spring Boot 的包扫描路径下，怎么办呢？也就是如何去加载第三方的Bean 呢？

大致意思：有一个对象没有找到，而这个对象又是必须的。原因：扫描配置文件时没有扫到该类所在的包，因而无法找到。未定义该类，或者注入有问题。解决办法： @MapperScan(value = “该类所在包”) @Mapper 将该注解添加在类上检查是否定义该对象并正确注入容器中 ...
