Apache骆驼:绑定非法参数异常 [英] Apache camel:bindy illegal argument exception

问题描述

我正在 POJO 和 CSV 之间进行数据格式转换，反之亦然.在将 CSV 转换为对象文件(解组)时，我收到了 int 数据类型的非法参数异常.仅用于字符串其工作正常.下面是我的POJO

I am doing data format conversion between POJO to CSV and vice versa. In this while converting CSV to Object file(Unmarshalling) i am getting illegal argument exception for int data type. Only for string its working fine. Below is my POJO

@CsvRecord(separator="//|",crlf="UNIX",generateHeaderColumns=false)
public class EmployeeVO implements Serializable{

    private static final long serialVersionUID = -663135747565879908L;

    @DataField(pos=1)
    private String name;

    @DataField(pos=3)
    private Integer age;

    @DataField(pos=2)
    private String grade;
        // getter setter
}   

csv 数据

sumit|4th standrad|22

上面的csv是从上面的POJO生成的.但是在将 CSV 转换为 POJO 时，我遇到了以下异常

the above csv is generated from the above POJO. But at the time of converting CSV to POJO i am getting folloing exception

java.lang.IllegalArgumentException: Parsing error detected for field defined at the position: 3, line: 1

推荐答案

需要指定csv记录如下

You need to specify the csv record as follows

@CsvRecord(separator = "\\|")
