java - Couchbase 存储库 BeanCreationException
问题描述
嗨，请有人帮忙。我在加载应用程序上下文期间收到 BeanCreationException。我正在尝试加载以下bean：
package org.stevie.spring.test.webmvc.household;
import org.springframework.data.couchbase.repository.CouchbaseRepository;
import org.stevie.spring.test.webmvc.domain.Household;
@Repository
public interface HouseholdRepository extends CouchbaseRepository<Household, String> {
}
控制台给了我日志信息： Invocation of init method failed; 嵌套异常是 java.lang.NullPointerException。
我正在加载另一个运行良好的存储库 bean：
package org.stevie.spring.test.webmvc.member;
import org.springframework.data.couchbase.repository.CouchbaseRepository;
import org.springframework.stereotype.Repository;
import org.stevie.spring.test.webmvc.domain.Member;
@Repository
public interface MemberRepository extends CouchbaseRepository<Member, String> {
}
在组件扫描中检测到有故障的 bean，但 spring 框架无法实例化它。谢谢你的帮助。
这是堆栈跟踪：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'householdRepository' defined in org.stevie.spring.test.webmvc.household.HouseholdRepository defined in @EnableCouchbaseRepositories declared on CouchbaseConfig: Invocation of init method failed; nested exception is java.lang.NullPointerException
