为什么我无法在/friends/userId/friendId/nickname方创建@JoinColumn？它抛出：
OneToMany当我更改方向时 - 将2017-05-17 09:13:34.063 WARN 7724 --- [ main] o.s.b.f.s.DefaultListableBeanFactory : Bean creation exception on non-lazy FactoryBean type check: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'roleMapper' defined in file [C:\MyProjects\myjnia\Myjnia_Inzynier\target\classes\com\carwash\mappers\RoleMapper.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in com.carwash.MyjniaInzynierApplication: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.annotation.ProxyTransactionManagementConfiguration': Initialization of bean failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'org.springframework.context.annotation.ConfigurationClassPostProcessor.importRegistry' available

放在JoinColumn侧，它可以正常工作，但我希望从Wash表中引用Wash。
Admin上课：
Admin public class Admin {
private Integer adminId;
private User userId;
private List<Wash> washId;
@OneToMany(mappedBy = "washAdmin", fetch = FetchType.LAZY)
@JoinColumn(name = "washId")
public List<Wash> getWashId() {
return washId;
}
上课：
Wash答案 0 :(得分：0)
在这种情况下，你需要使你的关系双向，你有两个选择，要么你有单向关系，而joinColumn将在拥有实体中，否则你将具有单向。
检查此示例如何创建单向关系

JoinColumn应该是非常严格的（在你的情况下没有收集的那个）并且mappedby应该是非严格的
