Spring错误——factory-bean reference points back to the same bean definition

  • 背景:学习Spring,在使用注解@Bean的name属性配置<bean>实例时,不能注册实例成功
  • 报错
    复制代码
    WARNING: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanDefinitionStoreException:

  • 报错原因:Bean注解的value或者name值问题 在一个容器中存在的相同或者大小写相同的情况。类Configure装配到Bean容器中的默认id为configure,@Bean注解的name值与之存在冲突
    复制代码
    package com.jing.spring.annotation;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    public class Configure {
    
        @Bean(name = {"configure","configure1"})
        public BeanConfigureI beanCon(){
            return new BeanConfigureImpl();
        }
    }
    复制代码
  • 解决方法:将注解@Bean的name属性值中的configura修改一下即可
    复制代码
    package com.jing.spring.annotation;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    public class Configure {
    
        @Bean(name = {"configure2","configure1"})
        public BeanConfigureI beanCon(){
            return new BeanConfigureImpl();
        }
    }
    复制代码
