RESTEasy + Jackson：如何在响应中排除字段？

问题描述

我正在将我的Java Web应用程序从基于servlet的迁移到JAX-RS。因为我正在使用Jboss，所以我也会使用（默认情况下）RESTEasy。

I'm migrating my Java web application from servlet-based to JAX-RS. Since I'm using Jboss I'll also use (by default) RESTEasy.

在我的servlet中，我使用Jackson序列化/反序列化JSON; Jackson允许我以编程方式过滤字段的包含/排除，例如：

In my servlets I use Jackson to serialize/deserialize JSON; Jackson allows me to filter programatically the inclusion/exclusion of fields, for example:

ObjectMapper mapper = new ObjectMapper().setVisibility(JsonMethod.FIELD,
Visibility.ANY);

String[] ignorableFieldNames = { "id", "name" };

FilterProvider filters = new SimpleFilterProvider().
addFilter("f123",SimpleBeanPropertyFilter.serializeAllExcept(ignorableFieldNames));

mapper.filteredWriter(filters).writeValueAsString(object);

RESTEasy提供Jackson支持，但它似乎是透明地嵌入开发人员所以我不是能够进入低级别以包含/排除字段。这是可行的吗？

RESTEasy provides Jackson support, but it seems that it is embedded transparently to the developer so I'm not able to get to the low-level to include/exclude fields. Is this feasible?

推荐答案

你可以使用以声明方式配置几乎所有内容。在你的情况下， @JsonIgnore 应该足够了。

You can use Jackson annotations to declaratively configure pretty much everything. In your case, @JsonIgnore should suffice.

你可以使用如果您不想一直忽略这些字段。

You can use JSON views if you don't want to ignore those fields all the time.

如果您无法修改相关类的代码（例如，因为它位于第三方库中）

If you can't modify the code of the class in question (say, because it's in a third-party library) mix-ins have you covered.

如果仍然发现你需要访问 ObjectMapper ：。
