我正在研究Spring Data MongoDB 聚合框架。错误：org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'aggregationBasicApplication': Unsatisfied dependency expressed through field 'productRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property aggregate found for type Product!    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:596) ~[spring-beans-5.1.7.RELEASE.jar:5.1.7.RELEASE]    at org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:90) ~[spring-beans-5.1.7.RELEASE.jar:5.1.7.RELEASE]    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessProperties(AutowiredAnnotationBeanPostProcessor.java:374) ~[spring-beans-5.1.7.RELEASE.jar:5.1.7.RELEASE]    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1411) ~[spring-beans-5.1.7.RELEASE.jar:5.1.7.RELEASE]    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:592) ~[spring-beans-5.1.7.RELEASE.jar:5.1.7.RELEASE]Product.java@Documentpublic class Product {    @Id    private final String id;    private final String warehouse;    private final float price;    public Product(String id, String warehouse, float price) {        this.id = id;        this.warehouse = warehouse;        this.price = price;    }    public String getId() {        return id;    }    public String getWarehouse() {        return warehouse;    }    public float getPrice() {        return price;    }}

Answer 1

花了很多小时后，我没有找到解决办法，为什么薄的东西坏了。我将所有这 3 个类放在同一个包中：xpadro.spring.data.repository. 现在它工作正常。任何人都知道是什么导致了真正的问题？

ProductRepository.java

ProductRepositoryCustom.java

ProductRepositoryImpl.java
