在REST webservices中与Content-Type“Application/x-www-form-urlencoded”作斗争

Question

感谢您就我在CXF REST提供商方面面临的以下问题提供建议。

我使用Apache CXF开发了REST web服务服务器。以下是合同定义。请注意，这是在Camel上下文中使用的。

public class PaymentSandboxService {

    @POST
    @Consumes({"application/json", "application/x-www-form-urlencoded"})
    @Produces({"application/json", "application/x-www-form-urlencoded"})
    @Path("/2_1/payment/{endUserId}/transactions/amount")
    public Response charge(@Body
    final AmountTransaction amountTransaction, @PathParam("endUserId")
    final String endUserId) throws IOException {

        return null;
    }
}

以下是我的bean定义：

    <cxf:rsServer id="rsServer" address="/{{publicAddress}}"  serviceClass="a.b.cPaymentSandboxService"
        loggingFeatureEnabled="true">
        <cxf:providers>
            <ref bean="jsonProvider" />
            <ref bean="formUrlEncodeProvider" />
        </cxf:providers>
    </cxf:rsServer>


<bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.JSONProvider">
  <property name="marshallAsJaxbElement" value="true" />
</bean>
<bean id="formUrlEncodeProvider" class="org.apache.cxf.jaxrs.provider.FormEncodingProvider" />

当我发送内容类型为“application/json”的请求时，一切正常。但当发送内容类型为“application/x-www-form-urlencoded”的请求时，请求会命中服务器，但在将正文转换为所需的数据类型时失败。下面是我在Fuse-esb日志中获得的日志部分。

一份汤（谢尔盖的）http://cxf.547215.n5.nabble.com/Consume-quot-application-x-www-form-urlencoded-quot-Content-Type-in-REST-Web-Service-cxf-rsServer-td5730399.html#a5730446

不同的解决方案包括：

• 使用Form或MultivaluedMap参数代替AmountTransaction，并手动填充AmountTransaction
• 有一个自定义提供商（如您所建议）
• 将cxf扩展名@FormParam（“”）与AmountTransaction一起使用
• 使用JAX-RS 2.0@BeanParam，并使用FormParam注释AmountTransaction属性
