Jersey / JAX-RS资源方法输入bean验证 [英] Jersey/JAX-RS resource method input bean validation

问题描述

我通过DropWizard 0.7.1使用Jersey / JAX-RS来公开RESTful服务端点。我的所有实体POJO都注释了JAX-RS和Hibernate / JSR-303 bean验证注释，如下所示：

I am using Jersey/JAX-RS via DropWizard 0.7.1 to expose RESTful service endpoints. I have all of my entity POJOs annotated with both JAX-RS and Hibernate/JSR-303 bean validation annotations like so:

public class Widget {
    @JsonProperty("fizz")
    @NotNull
    @NotEmpty
    private String fizz;     // Can't be empty or null

    @JsonProperty("buzz")
    @Min(value=5L)
    private Long buzz;       // Can't be less than 5

    // etc.
}

当资源方法收到其中一个POJO作为输入时（在引擎盖下，DropWizard已经将HTTP实体JSON反序列化为 Widget 实例），我会喜欢根据Hibernate / Bean验证注释验证它：

When a resource method receives one of these POJOs as input (under the hood, DropWizard has already deserialized the HTTP entity JSON into a Widget instance), I would like to validate it against the Hibernate/Bean Validation annotations:

@POST
Response saveWidget(@PathParam("widget") Widget widget) {
    // Does DropWizard or Jersey have something built-in to automagically validate the
    // 'widget' instance?
}

可以将DropWizard / Jersey配置为验证我的小部件实例，我不必在这里写任何验证码？

Can DropWizard/Jersey be configured to validate my widget instance, without me having to write any validation code here?

推荐答案

添加 @Valid 在 @PathParam 之前用泽西岛验证。

Add @Valid before @PathParam to validate with Jersey.

参见 https://jersey.java.net/documentation/latest/bean-validation.html#d0e12201

您可能需要进行一些配置。

You may have to do some configuration.
