您可以使用条件bean创建Configuration类：

@Configuration
class ConditionalBeanConfiguration {

  @Bean
  @Conditional... <--
  ConditionalBean conditionalBean(){
    return new ConditionalBean();
  };

}

字符串
所以它可能看起来像：

@Configuration
class MapperBeanConfiguration {

    @Bean
    @ConditionalOnProperty(name = "my.property.enabled", havingValue = "true")
    public MyMapper myMapperImplV1() {
        return new MyMapperImplV1();
    }

    @Bean
    @ConditionalOnProperty(name = "my.property.enabled", havingValue = "false", matchIfMissing = true)
    public MyMapper myMapperImplV2() {
        return new MyMapperImplV2();
    }

}
