解决Consider defining a bean of type ‘XXX’ in your configuration.

报错原因:springboot自动注入,启动报错了。

没有找到对应的bean的原因是@SpringBootApplication没有扫描到

Description: 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. 解决方法

1.检查自己写的注解是否错了。

2.在springboot的配置文件添加,mybatis的配置如下所示:

mybatis: typeAliasesPackage: com.xxx.xxx.dao.entity mapperLocations: classpath:mapper/*.xml
  • 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。

    ②或在启动类上加上@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 UserMapper { } 点击资料获取
