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

问题描述

我做的到CSV POJO之间的数据格式转换，反之亦然。在此同时，转换CSV到目标文件（解组）我得到的int数据类型非法参数异常。只有字符串其工作罚款。
下面是我的POJO

  @CsvRecord（分隔符=// |CRLF =UNIX，generateHeaderColumns = FALSE）
公共类EmployeeVO实现Serializable {    私有静态最后的serialVersionUID长= -663135747565879908L;    @DataField（POS = 1）
    私人字符串名称;    @DataField（POS = 3）
    私人整数年龄;    @DataField（POS = 2）
    私人字符串等级;
        //吸气二传手
}
 

CSV数据

  SUMIT | 4 standrad | 22
 

上述的csv从上述POJO生成。但在CSV转换成POJO我得到folloing异常时

  java.lang.IllegalArgumentException异常：3，行：在位置定义的字段检测分析错误1
 

以下是我的骆驼 - 供大家参考上下文文件

解决方案

您需要按以下方式指定CSV记录

  @CsvRecord（分隔符=\\\\ |）
 

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 data

sumit|4th standrad|22

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

following are my camel - context file for your reference

marshal

<route>
        <from uri="cxf:bean:rtoemplyeeService"/>
        <convertBodyTo type="java.lang.String" id="stringInput"/>
        <bean ref="govtEmpBean" method="getEmployeeCSV" beanType="govtEmpBean" id="govtEmp"/>
        <log message="before marshalling ================== ${body}"/>
        <marshal ref="bindyDataformat">
            <bindy type="Csv" packages="com.mycompany.converter.vo"/>
        </marshal>
        <log message="after marshalling ================== ${body}"/>
        <to uri="file://D:/JATO_WORK/repo_bkp/csv/"/>
        <setBody>
            <simple>CSV output is generated at file system </simple>
        </setBody>
    </route>

un marshal

 <route id="csvtoobject">
        <from uri="file://D:/JATO_WORK/repo_bkp/csv?delay=10000&amp;initialDelay=10"/>
        <log message="csv string ============= ${body}"/>
        <unmarshal ref="bindyDataformat"/>
        <log message="${body}"/>
        <bean ref="govtEmpBean" method="printCSVObject" beanType="govtEmpBean" id="govtEmp"/>
    </route>

解决方案

You need to specify the csv record as follows

@CsvRecord(separator = "\\|")
