如何在不继承spring-boot-starter-web的情况下在Spring Boot中获取ObjectMapper实例？(How can I get an ObjectMapper instance in Spring Boot without inheriting from spring-boot-starter-web?)

 我正在玩Spring Boot 2.0.0M2，试图创建一个CLI应用程序，而不是一个Web应用程序。 我的问题是甚至包括 
 
  compile 'org.springframework.boot:spring-boot-starter'
  compile 'org.springframework.boot:spring-boot-starter-json'
 
 在我的构建中，ObjectMapper不是由Boot创建的 
 
Bean method 'jacksonObjectMapper' not loaded because @ConditionalOnClass did not find required class 'org.springframework.http.converter.json.Jackson2ObjectMapperBuilder'
 
 当您想要Spring Boot实例并配置Jackson但不想启动Web服务器时，最佳做法是什么？ 

I'm playing around with Spring Boot 2.0.0M2, trying to create a CLI application, not a web one. My problem is that even including 
 
  compile 'org.springframework.boot:spring-boot-starter'
  compile 'org.springframework.boot:spring-boot-starter-json'
 
in my build, ObjectMapper is not created by Boot because
 
Bean method 'jacksonObjectMapper' not loaded because @ConditionalOnClass did not find required class 'org.springframework.http.converter.json.Jackson2ObjectMapperBuilder'
 
What's the best practice when you want to have Spring Boot instance and configure Jackson but don't want to start a web server?
