spring - Spring-多模块未加载bean-获取异常无法加载ApplicationContext

Question

我有一个多模块弹簧基础应用程序定义为并使用@Import 导入另一个模块的配置，但我仍然低于异常 -

java.lang.IllegalStateException: Failed to load ApplicationContext
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'loyaltyService': Unsatisfied dependency expressed through field 'loyalistRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.a.b.loyalty.data.repository.LoyalistRepository' available: expected at least 1 bean which qualifies as autowire candidate.

Answer 1

我认为你必须添加@EnableJpaRepositories和@EntityScan

package com.a.b.loyalty.service;

@SpringBootApplication
@EnableJpaRepositories(basePackages="<repository package name>")
@EnableTransactionManagement
@EntityScan(basePackages="<entity package name>")
public class LoyaltyApplication {
    public static void main(String[] args) {
        SpringApplication.run(LoyaltyApplication.class, args);
    }
}
