spring-boot - Spring Boot 自定义 HttpMessageConverter

Question

如何配置spring boot添加自定义custom HttpMessageConverter ？我正在使用

AbstractHttpMessageConverter

但我不知道在哪里添加配置。使用 Spring MVC Classic 将是:

 <mvc:message-converters register-defaults="true">
      <bean class="com.mypackage.TsvMessageConverter"/>
   </mvc:message-converters>

但是Spring boot，在Application.java中？

@SpringBootApplication
@ComponentScan
@EnableAutoConfiguration
public class Application {}

Answer 1

如果 com.mypackage.TsvMessageConverter 是从 AbstractHttpMessageConverter 类扩展的，那么用“@Component”注释标记它就足够了。

来自spring docs :

You can contribute additional converters by simply adding beans of that type in a Spring Boot context. If a bean you add is of a type that would have been included by default anyway (like MappingJackson2HttpMessageConverter for JSON conversions) then it will replace the default value.
