异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'companyController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.seing.eepsweb.service.company.CompanyService com.seing.eepsweb.web.company.CompanyController.companyService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'companyService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void com.seing.eepsweb.service.company.CompanyService.setCompanyDao(com.seing.eepsweb.repository.CompanyDao); nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'companyDao': FactoryBean threw exception on object creation; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property company found for type com.seing.eepsweb.entity.Company

发生异常的代码：

public interface CompanyDao extends PagingAndSortingRepository<Company, Long>, JpaSpecificationExecutor<Company> {

Page<Company> findByCompanyId(Long companyid,Pageable pageRequest);
}

解决原因和方法：

原因：No property company found for type com.seing.eepsweb.entity.Company

原理：在Page<Company> findByCompanyId(Long companyid,Pageable pageRequest); 中CompanyId一定要是Company实体类中的属性，否则使用自动注入@Autowired就无法通过。

所以把Page<Company> findByXXX(Long companyid,Pageable pageRequest);中的XXX改为Company实体类中的属性，或者删除：Page<Company> findByCompanyId(Long companyid,Pageable pageRequest); 就可以解决。
