java - 与Jackson的http:outbound-gateway抛出解析异常，导致响应不匹配

我有个问题：

如何处理第三方以http：outbound-gateway（以及其中的jackson-com.fasterxml.jackson一种）未知的格式返回json响应的情况。



Spring集成配置：

<int:chain input-channel="ul_campaignSetup_channel">
    <int:header-enricher>
        <int:header name="Content-Type" value="application/json; charset=UTF-8"/>
    </int:header-enricher>

    <int-http:outbound-gateway id="ulHttpOutboundGateway"
                               http-method="POST"
                               url="${request.url}"
                               extract-request-payload="true"
                               error-handler="campaignSetupResponseHandler"
                               expected-response-type="integration.ul.message.CampaignSetupResponse"
                               request-factory="ulRequestFactory">
        <int-http:uri-variable name="url" expression="headers.url"/>
    </int-http:outbound-gateway>
    <int:service-activator method="handle" ref="campaignSetupResponseHandler" />

    <int:json-to-object-transformer id="myId" />

</int:chain>

<bean id="campaignSetupResponseHandler" class="integration.ul.message.CampaignSetupResponseHandler" />

<bean id="jackson2http" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
    <property name="objectMapper" ref="ulObjectMapper" />
</bean>

<bean id="ulObjectMapper" class="com.fasterxml.jackson.databind.ObjectMapper"/>

<bean id="ulRequestFactory" class="org.springframework.http.client.SimpleClientHttpRequestFactory">
    <property name="connectTimeout" value="10000" />
    <property name="readTimeout" value="10000" />
</bean>

public class CampaignSetupResponse {

    private String status;

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }
}

纠正来自第三方的JSON响应（有效）：

{
  "status" : "1"
}

来自第三方的不正确的JSON响应（导致异常）：

{
  "nonExistingProperty": "non existing value"
}

我得到的异常：

org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: Unrecognized field "nonExistingProperty" (class integration.ul.message.CampaignSetupResponse), not marked as ignorable (one known property: "status"])
at [Source: sun.net.www.protocol.http.HttpURLConnection$HttpInputStream@20fddd96; line: 2, column: 27] (through reference chain: integration.ul.message.CampaignSetupResponse["nonExistingProperty"]); nested exception is com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "nonExistingProperty" (class integration.ul.message.CampaignSetupResponse), not marked as ignorable (one known property: "status"])

at org.springframework.http.converter.json.MappingJackson2HttpMessageConverter.read(MappingJackson2HttpMessageConverter.java:220)

如何处理此解析异常？

我尝试了几种带有错误通道（http：outbound-gateway似乎没有一个）和错误处理程序（对于诸如500的实际http错误的处理程序）的解决方案，但无法处理Jackson解析异常。

大家欢迎任何想法，欢呼！

最佳答案

已经达成共识的接口是什么？
老实说，第二个响应与接口定义不符-我只是让他们修复它。 （对我来说，这看起来像是某种东西，例如不存在“ status”变量或其他东西）。
否则，您需要自己处理响应。
