public class ConverterRoute implements RoutesBuilder {

    public void addRoutesToCamelContext(CamelContext context) throws Exception {
        Tracer tracer = new Tracer();
        tracer.setTraceOutExchanges(true);

        // we configure the default trace formatter where we can
        // specify which fields we want in the output
        DefaultTraceFormatter formatter = new DefaultTraceFormatter();
        formatter.setShowOutBody(true);
        formatter.setShowOutBodyType(true);

        // set to use our formatter
        tracer.setFormatter(formatter);

        context.addInterceptStrategy(tracer);
        context.addRoutes(new RouteBuilder() {

            public void configure() {

    @XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@CsvRecord(separator = ",", skipFirstLine = true)
public class EmployeeDTO implements Serializable{
@XmlAttribute
      @DataField(pos = 1)
      private int employeeId;
      @XmlAttribute
      @DataField(pos = 2)
      private String firstName;
      @XmlAttribute
      @DataField(pos = 3)
      private String lastName;
      @XmlAttribute
      @DataField(pos = 4)
      private String role;
}

我收到了以下错误：

启动........
log4j：WARN找不到logger（org.apache.camel.impl.DefaultCamelContext）的appender。 log4j：WARN请正确初始化log4j系统结束........

在欲望文件夹中没有生成转换后的xml。

首先，WARNING表示类路径中没有log4j配置文件。尝试添加一个名为＆＃34; log4j.properties＆＃34;的文件。在资源目录中包含以下内容：

log4j.rootLogger=INFO, out
# uncomment the following line to turn on Camel debugging
log4j.logger.org.apache.camel=INFO
log4j.logger.org.apache.camel.component.mongodb=DEBUG
log4j.logger.org.springframework=WARN
log4j.appender.out=org.apache.log4j.ConsoleAppender
log4j.appender.out.layout=org.apache.log4j.PatternLayout
log4j.appender.out.layout.ConversionPattern=[%30.30t] %-30.30c{1} %-5p %m%n

通过以上操作，您将获得IDE中的日志，并可以查看正在进行的操作。

最后，您可以使用JAXB而不是XTREAM。您唯一需要做的就是使用JAXB注释注释EmployeeDTO。

使用apache camel将CSV文件转换为xml文件：未创建XML文件
