我正在尝试设置一个http:inbound-gateway
只接受 json 的。我的 xml 配置看起来像。
<int-http:inbound-gateway id="inboundGateway"
supported-methods="POST"
request-payload-type="eu.model.MyRequest"
request-channel="inputChannel"
mapped-response-headers="Return-Status, Return-Status-Msg, HTTP_RESPONSE_HEADERS"
path="/myService"
reply-timeout="50000"
message-converters="converters"
merge-with-default-converters="false"
validator="myValidator">
<int-http:request-mapping consumes="application/json"/>
</int-http:inbound-gateway>
<util:list id="converters">
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
</util:list>
我已经看到,从 5.2 版本开始,验证器可用于在发送到通道之前检查有效负载,但我似乎找不到示例。添加validator="myValidator"
似乎验证了 myRequest。
但是,尽管<int-http:request-mapping consumes="application/json"/>
将内容限制为有效的 json 并且 Validator 发出HTTP Status 400 – Bad Request
错误是在 html 中返回的?
如何覆盖它以返回自定义 json 响应?
编辑 1 这是我的完整 xml 配置
<int-http:inbound-gateway id="inboundGateway"
supported-methods="POST"
request-payload-type="eu.neurocom.wind.msdp.cis.model.MyRequest"
request-channel="inputChannel"
reply-channel="responseChannel"
error-channel="errorChannel"
mapped-response-headers="Return-Status, Return-Status-Msg, HTTP_RESPONSE_HEADERS"
path="/myservice"
reply-timeout="50000"
message-converters="converters"
merge-with-default-converters="false"
validator="myValidator">
<int-http:request-mapping consumes="application/json" produces="application/json" />
</int-http:inbound-gateway>
<util:list id="converters">
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
</util:list>
<int:service-activator
input-channel="errorChannel"
output-channel="responseChannel"
ref="globalExceptionHandler"
method="handleError"
/>
<int:service-activator ref="incomingActivator" input-channel="inputChannel" output-channel="responseChannel" method="handle"></int:service-activator>
我的端点激活器方法看起来像
public Message<MyResponse> handle(Message<MyRequest> message) {
logger.info("Received {}", message);
...}
如果在激活器中引发错误,则错误通道将返回我的自定义 json 响应,否则甚至在记录我在 text/html 中的响应下方得到的消息之前;。
<body>
<h1>HTTP Status 400 – Bad Request</h1>
<hr class="line" />
<p><b>Type</b> Status Report</p>
<p><b>Message</b> Validation failure</p>
<p><b>Description</b> The server cannot or will not process the request due to something that is perceived to be a
client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
</p>
<hr class="line" />
<h3>Apache Tomcat/8.5.58</h3>
编辑 2 Bellow 是我的验证器类,调用了 looger,如果不存在 msidsn 则触发
public class MyRequestValidator implements Validator {
private static final Logger logger = LoggerFactory.getLogger(MyRequestValidator.class);
@Override
public boolean supports(Class<?> clazz) {
return CisRequest.class.equals(clazz);
}
@Override
public void validate(Object target, Errors errors) {
logger.debug("validatorCalled");
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "msisdn", "msisdn.required");
}
}
