Question

我正在尝试将相同的可嵌入对象映射到我的实体类。

Set

以下是我的配置文件

     @Entity
    public class Person {
        @Embedded
        public Address home;

        @Embedded
        public Address work;
    }
    @Embeddable
    public class Address {
        public String street;
        public String poBox;

    }

<?xml version="1.0" encoding="UTF-8"?>

启动时它仍然给我以下错误

<bean id="transactionManager"

如您所见，我在配置中使用 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring/hibernate-config.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: Repeated column in mapping for entity: com.app.db.entities.Person column: street (should be mapped with insert="false" update="false") 。我这样认为你可以在课堂上多次使用嵌入对象。

如果我为命名策略提供一个随机字符串，则表示未找到该类失败。所以我假设读取配置。这里有什么我想念的吗？任何帮助表示赞赏。

ImplicitNamingStrategyComponentPathImpl不起作用
