I am using Spring Integration to implement a solution where i have to read file and search some data in other file and then i need to write on xml file .
1)I have created integration flow like that :
@Bean
public IntegrationFlow fileIntegrationFlow(){
return IntegrationFlows.from(readFilefromDirectory(), fileInboundPollingConsumer())
.split(new FileSplitter())
.transform(dataDataTransformer())
.transform(Transformers.marshaller(getMarshaller(),resultTransformer(),true))
.wireTap(logChannel())
.handle(fileWriter()).get();
}
2)File writer i have configured below like that :
@Bean
public FileWritingMessageHandler fileWriter() {
FileWritingMessageHandler writer = new FileWritingMessageHandler(
new File("D://example_tex//write"));
writer.setExpectReply(false);
writer.setFileExistsMode(FileExistsMode.APPEND);
writer.setAppendNewLine(true);
writer.setFileNameGenerator(fileNameGenerator());
return writer;
}
3)I have configured marshaller like that :
@Bean
public Marshaller getMarshaller(){
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setPackagesToScan("com.springintegration.example");
return marshaller;
}
4)I have used Result transformer below like this :
@Bean
public ResultTransformer resultTransformer() {
ResultToStringTransformer resultToStringTransformer= new ResultToStringTransformer();
Properties p = new Properties();
p.setProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
resultToStringTransformer.setOutputProperties(p);
return resultToStringTransformer;
}
So above is my configuration for Spring Integration flow .
My Question is Below :
1)After splitting one message flow goes further and it is processed and written in file .But in xml file while writing where should i configure header and footer so that it is written once and proper xml file is generated .
我有一个客户对象，它是在monitoringdata对象中列出的。我需要为这个对象创建xml文件。 @XmlRootElement 公共类MonitoringData {
List<Customer> customerList ;
public List<Customer> getCustomerList() {
return customerList;
}
public void setCustomerList(List<Customer> customerList) {
this.customerList = customerList;
}
}
Final Xml file after all customer object added in file Shoul look like this.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<MonitoringData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="java:java.lang.String">
<customer><cust-name>33334444</cust-name></customer>
<customer><cust-name>3333333</cust-name></customer>
</MonitoringData>
我能够编写客户对象部分并逐一编写但是如何在输出文件中添加Monitoringdata对象和xml头。
更新的代码流程： 我已经创建了这样的流程但是文件没有被创建：我是否想念一些东西。
@Bean
public IntegrationFlow fileIntegrationFlow(){
return IntegrationFlows.from(readFilefromDirectory(), fileInboundPollingConsumer())
.split(new FileSplitter())
.transform(dataDataTransformer())
.wireTap(logChannel())
.aggregate()
.<List<Customer>>handle((p, h) -> new MonitoringData(p))
.transform(Transformers.marshaller(getMarshaller(),resultTransformer(),true))
.handle(fileWriter()).get();
}
数据转换器：
@MessageEndpoint
public class DataTransformer {
@Transformer
public Customer transferData(String payload){
Customer customer = new Customer();
customer.setCustName(payload);
return customer;
}

答案 0 :(得分：0)
好吧，我认为我们应该将页眉和页脚视为要追加的消息。
FileSplitter可以发出FileMarker s（new FileSplitter(true, true)），其中FileMarker.Mark.START您可以转换为header消息，因此FileMarker.Mark.END到footer。
您的dataDataTransformer()应该关注FileMarker.Mark转换为适当的对象XML字符串以进行下游追加。
我想您为了这个目的需要.filter()来绕过.marshaller()转换，因为您没有从FileMarker.Mark获得适当的对象来编组有效的XML。
为此，我这样做：
@Bean
public IntegrationFlow fileIntegrationFlow() {
return IntegrationFlows.from(readFilefromDirectory(), fileInboundPollingConsumer())
.split(new FileSplitter(true, true))
.filter(p -> !(p instanceof FileSplitter.FileMarker.Mark),
f -> f.discardChannel("convertToHeaderOrFooterChannel"))
.transform(dataDataTransformer())
.transform(Transformers.marshaller(getMarshaller(),resultTransformer(),true))
.wireTap(logChannel())
.channel("appendToFile")
.handle(fileWriter()).get();
}
.filter()检查payload类型，然后放弃convertToHeaderOrFooterChannel Mark转换为所需的字符串。
convertToHeaderOrFooterChannel流程可能如下所示：
@Bean
public IntegrationFlow markTransformationFlow() {
return IntegrationFlows.from("convertToHeaderOrFooterChannel")
.transform(...)
.channel("appendToFile");
}
注意.channel（＆＃34; appendToFile＆＃34;）用法。此markTransformationFlow()将其结果发送到该主渠道中fileWriter()之前的那个渠道！

根据新收入
在文件中添加所有客户对象后的最终Xml文件。
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<MonitoringData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="java:java.lang.String">
<customer><cust-name>33334444</cust-name></customer>
<customer><cust-name>3333333</cust-name></customer>
</MonitoringData>
像33334444 3333333这样的数据我将解决方案视为.aggregate()来构建List<Customer>，然后MonitoringData作为结果。
只有在那之后，我才会完全整理并立即写入文件。
