当控制器方法返回@responsebody时，即使我把

when controller method return is @responsebody , even if i put

<bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"> <property name="prefixJson" value="true" /> </bean>

没有&& {}插入json数据的前面。有谁知道是什么原因？

there will no && {} insert at the front of json data. anyone knows what is reason?

推荐答案

中的JSON> @RequestBody / @ResponseBody 由 MappingJacksonHttpMessageConverter 处理，该配置在 AnnotationMethodHandlerAdapter.messageConverters 。

JSON in @RequestBody/@ResponseBody is handled by MappingJacksonHttpMessageConverter which is configured in AnnotationMethodHandlerAdapter.messageConverters.

在不干扰其他功能的情况下配置它的简单方法是创建一个 BeanPostProcessor 来拦截创建 AnnotationMethodHandlerAdapter ，例如，参见这里。

The easy way to configure it without interference with other features is to create a BeanPostProcessor to intercept creation of AnnotationMethodHandlerAdapter, see, for example, here.
