配置Spring的MappingJacksonHttpMessageConverter [英] Configure Spring's MappingJacksonHttpMessageConverter

问题描述

我在Spring MVC中使用 MappingJacksonHttpMessageConverter 来自动序列化这样的对象：

I am using MappingJacksonHttpMessageConverter in Spring MVC to automatically serialize objects like this:

@RequestMapping(value="/*/getAccount", method=RequestMethod.GET)
@ResponseBody
public Account getAccountAction() {
    Account account = accountService.getAccount();
    return account;
}

是否可以配置对象的哪些属性被序列化？在我的示例中， Account 有3个集合作为属性，序列化所有这些内容将导致一个巨大的对象树。在这里，我只想返回扁平物体。

Is it possible to configure which properties of the object are serialized? In my example, Account has 3 collections as properties and serializing all these contents would result in a huge object tree. Here I only want to return the flat object.

此致

Sincerely, Erik

推荐答案

您是否已尝试使用杰克逊注释？

Did you already try to use the Jackson Annotations?

有注释 @ JsonIgnoreProperties ，可用于忽略类级别上的序列化的给定属性列表是 @JsonIgnore 来标记属性忽略字段级别的序列化。

There is the Annotation @JsonIgnoreProperties that can be used to ignore a given list of properties for serialization on class level and there is @JsonIgnore to mark properties to ignore for serialization on field level.
