What is the equivalent of register defaults = “false” in Java – spring 4?

How to configure a custom message converter with register defaults = "false" in an XML free project using spring 4?

<mvc:annotation-driven register-defaults="false">
  <mvc:message-converters>
    <bean class="myproject.MyCustomHttpMessageConverter"/>
  </mvc:message-converters>
</mvc:annotation-driven>

At present, I have this configuration:

@Configuration
@EnableWebMvc
@ComponentScan
public class TestDataConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        final MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converters.add(converter);
    }
}

thank you

Solution

Your Java configuration is similar to register defaults = "false" in the XML configuration You don't need to do anything However, if you want to register defaults, you must extend from webmvcconfigurationsupport and add the last line specified in the following code snippet

@Configuration
@EnableWebMvc
@ComponentScan
public class TestDataConfig extends WebMvcConfigurationSupport {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        final MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converters.add(converter);
        super.addDefaultHttpMessageConverters(); // Have to call this explicitly to register Default Message Converters.
    }
}
