添加消息转换器configureMessageConverters和extendMessageConverters区别

添加自定义消息转换器不覆盖默认转换器请使用extendMessageConverters
添加自定义会覆盖默认转换器使用configureMessageConverters

configureMessageConverters

/**
	 * Configure the {@link HttpMessageConverter HttpMessageConverters} to use for reading or writing
	 * to the body of the request or response. If no converters are added, a
	 * default list of converters is registered.
	 * 
Note that adding converters to the list, turns off
	 * default converter registration. To simply add a converter without impacting
	 * default registration, consider using the method
	 * {@link #extendMessageConverters(java.util.List)} instead.
	 * @param converters initially an empty list of converters
	 */
	default void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
     
	}

意思是
配置HttpMessageConverters以用于读取或写入请求或响应的主体。如果未添加转换器，则会注册转换器的默认列表。请注意，向列表中添加转换器将关闭默认转换器注册。只需添加一个转换器而不影响默认注册，请考虑使用 extendMessageConverters
extendMessageConverters

/**
	 * A hook for extending or modifying the list of converters after it has been
	 * configured. This may be useful for example to allow default converters to
	 * be registered and then insert a custom converter through this method.
	 * @param converters the list of configured converters to extend.
	 * @since 4.1.3
	 */
	default void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
     
	}

意思是
用于在配置转换器后扩展或修改转换器列表的钩子。这可能很有用，例如允许注册默认转换器，然后通过此方法插入自定义转换器。
