Question

我需要从spring-module.xml添加标头。我得到了低于回应

headers:    
file_name:  sample.txt
content_type:   text/plain

Payload: { "json":{ "type":"abcd","value":"1234" }}

在标题中我需要添加另一个字段，如“time：timestamp”这些标题我们应该只从spring-module.xml添加。期待下面的标题。

headers:    
file_name:  sample.txt
content_type:   text/plain
time:timestamp

下面的

是我的spring-module.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/integration"
  xmlns:beans="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                                 http://www.springframework.org/schema/context
                                 http://www.springframework.org/schema/context/spring-context.xsd">

<channel id="input"/>
  <transformer input-channel="input" output-channel="output">
    <beans:bean class="com.sample.PayloadValidation" >
    </beans:bean>
  </transformer>
<channel id="output"/>

</beans:beans>

我需要做些什么更改从spring-module.xml中添加一个更像“time”的标题..？

请参阅Header Enricher。

<int:header-enricher input-channel="in" output-channel="out">
    <int:header name="foo" value="123"/>
    <int:header name="bar" ref="someBean"/>
    <int:header name="baz" expression="@someBean.getHeaderValue(payload)"/>
</int:header-enricher>
