Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'cn.tedu.hello.mapper.UserMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 检查一下UserMapper注解和要扫描的包 以下为根据具体选用情况而定, 多用优先级的顺序问题 一般选用第3种 1 .是否使用在具体mapper上有到 @Mapper   2 . 是否使用在application文件中 mybatis: type-aliases-package: com.ayh.order.pojo mapper-locations: com.ayh.order.mappers 3 .是否使用在启动类上用到了@MapperScan(value="com.ayh.order.mappers") 是否在测试类上添加注解 @RunWith(SpringRunner.class) @SpringBootTest(classes = 具体测试类.class) public class orderMapperTests{ @Autowired UserMapper userMapper;

J2EE只是Java企业应用。我们需要一个跨J2SE/WEB/EJB的微容器,保护我们的业务核心组件(中间件),以延续它的生命力,而不是依赖J2SE/J2EE版本。
