java.lang.IllegalStateException: Failed to load ApplicationContext

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘person’ defined in file [D:\mydemo\Spring\Spring\target\classes\pojo\Person.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘java.lang.String’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

重点在加粗的文字部分，我才用spring自动装配的方法配置bean，但是没有提供无参构造，导致加载上下文失败。配置自动化装配，bean的实例化是通过无参构造函数完成的。
