我正在尝试使用bindy将csv文件转换为pojo，但收到错误
Pojo课程：
@CsvRecord(separator = ",")
public class PurchaseOrder {
@DataField(pos = 1)
private String name;
@DataField(pos = 2)
private BigDecimal price;
@DataField(pos = 3)
private int amount;
//getters, setters
}
主要课程
CamelContext context = new DefaultCamelContext();
context.addRoutes(new RouteBuilder() {
public void configure() {
from("file://data/inbox?noop=true")
.unmarshal()
.bindy(BindyType.Csv, PurchaseOrder.class)
.process(new Processor() {
public void process(Exchange exchange) throws Exception {
PurchaseOrder object = (PurchaseOrder) exchange.getIn().getBody();
System.out.println(object);
}
});
context.start();
Thread.sleep(3000);
context.stop();
data.csv中的文件inbox包含数据：
Camel in Action,39.95,"1"
这是我得到的错误：
Failed delivery for (...). Exhausted after delivery attempt: 1 caught: java.lang.NullPointerException
