Spring-Integration:如何通过网关触发文件读取

<int-file:inbound-channel-adapter directory="/data/in"
                                  filter="xmlFileFilter"
                                  channel="inputChannel">
    <int:poller fixed-delay="1000" />
</int-file:inbound-channel-adapter>

<bean id="xmlFileFilter" class="org.springframework.integration.file.filters.SimplePatternFileListFilter">
    <constructor-arg value="*.xml" />
</bean>

<int:service-activator input-channel="inputChannel" ref="fileHandler" method="handleFile" />

<bean id="fileHandler" class="com.example.FileHandler" />

public class FileHandler {
    public void handleFile(File file) {
        // 处理文件逻辑
        System.out.println("文件处理：" + file.getAbsolutePath());
    }
}
