springboot 工程启动报错之Consider defining a bean of type ‘XXX’ in your configuration.
一.问题 启动springboot后,报错,错误如下 `Field userEntityMapper in com.XXX.xxx.service.UserService required a bean of type ‘com.xxx.xxx.dao.UserEntityMapper’ that could not be found.
Action:
Consider defining a bean of type ‘com.xxx.xxx.dao.UserEntityMapper’ in your configuration.` 二.解决方法 步骤一: 在springboot的配置文件添加,mybatis的配置如下所示:
mybatis.config-location=classpath:mybatis/mybatis-config.xml mybatis.mapper-locations=classpath:mybatis/mapper/*.xml mybatis.type-aliases-package=cn.xxx.xxx.entity步骤二:
①将接口与对应的实现类放在与application启动类的同一个目录或者他的子目录下,这样注解可以被扫描到,这是最省事的办法。(没测试) ②或者在启动类上加上@MapperScan或者@ComponentScan注解,手动指定application类要扫描哪些包下的注解,如下所示:
@SpringBootApplication @ComponentScan(basePackages = {"com.xxx.xxx.dao"})③或者在接口上添加@Mapper注解。
@Mapper public interface Refsnp2Annotate2FunctionMapper {ps:之所以没有找到对应的Bean是因为,@SpringBootApplication没有扫描到。
