Thia吃了我的周末，我搜索了它，但可能会有几个可能导致它的问题，希望有人会帮助我。
我正在尝试使用第三个表通过一对多和多对一关系创建多对多关系，但我收到此错误：

在这里我试图填充一些虚拟数据：
@Component
public class StartOnStartUp implements ApplicationListener<ContextRefreshedEvent> {
@Autowired
private TouristFirstCategoryRepository touristFirstCategoryRepository;
@Autowired
private TouristSecondCategoryRepository touristSecondCategoryRepository;
@Autowired
private PoojaFirstCategoryRepository poojaFirstCategoryRepository;
@Autowired
private PoojaSecondCategoryRepository poojaSecondCategoryRepository;
@Override
@Transactional
public void onApplicationEvent(ContextRefreshedEvent arg0) {
PoojaFirstCategory poojaFirstCategory = new PoojaFirstCategory("StayaNarayan","SatayNarayan Ki pooja");
PoojaSecondCategory poojaSecondCategory = new PoojaSecondCategory("StayaNarayan","Pandit Brij Bhushan",23,1000);
PoojaPanditRelationShip poojaPanditRelationShip = new PoojaPanditRelationShip();
poojaPanditRelationShip.setPoojaFirstCategory(poojaFirstCategory);
poojaPanditRelationShip.setPoojaSecondCategory(poojaSecondCategory);
poojaFirstCategory.getPoojaPanditRelationShip().add(poojaPanditRelationShip);
poojaSecondCategoryRepository.save(poojaSecondCategory);
poojaFirstCategoryRepository.save(poojaFirstCategory);
}
我也在使用hibernate属性来创建基于实体类的表
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<!-- spring based scanning for entity classes -->
<property name="packagesToScan" value="first.varanasi.erp" />
<property name="jpaProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
答案 0 :(得分：1)
您应该在getter（或字段）上放置注释映射，而不是setter。所以不要这样：
@OneToMany(mappedBy = "poojaFirstCategory", cascade = CascadeType.ALL)
public void setPoojaPanditRelationShip(Set<PoojaPanditRelationShip> poojaPanditRelationShip) {
this.poojaPanditRelationShip = poojaPanditRelationShip;
}
你应该用这个：
@OneToMany(mappedBy = "poojaFirstCategory", cascade = CascadeType.ALL)
public Set<PoojaPanditRelationShip> getPoojaPanditRelationShip() {
return poojaPanditRelationShip;
}
HTH。
