RESTEasy + Jackson：如何在响应中排除字段？ [英] RESTEasy + Jackson: how to exclude fields in the response?

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 Jackson注释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 JSON视图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） mix- ins已经让你了解。

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 ：在RestEasy中访问Jackson Object Mapper 。

And if you still find that you need to access the ObjectMapper: Accessing Jackson Object Mapper in RestEasy.
