org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘com

问题描述

报错原因：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘com.ssm.test.JwtTest’: Unsatisfied dependency expressed through field ‘jwtHelper’: No qualifying bean of type ‘com.ssm.utils.JwtHelper’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

注入失败

原因分析：

1、检查要引入这个类有没有加入IOC容器中，类上有没有@Component注解之类的
2、检查启动类上包有没有扫描到@ComponentScan(“com.ssm.utils”)
