Test.java

@CsvRecord(separator = "\\|",skipField = true,name = "Test")
public class Test {

    @DataField(pos = 1,name = "ALT_NUM")
    private BigDecimal ALT_NUM;

    @DataField(pos = 2,name = "PRTNUM")
    private BigDecimal PRTNUM;

    @DataField(pos = 3,name = "UOMCOD")
    private Integer UOMCOD;

}

输出

* File.xml *

<?xml version='1.0' encoding='UTF-8'?>
<list>
    <com.john.Test>
            <ALT_NUM>55158</ALT_NUM>
            <PRTNUM>11901</PRTNUM>
            <UOMCOD>2346</UOMCOD>
    </com.john.Test>

我能够用单个文件中的所有字段生成xml文件。我想要单个xml文件中的单个记录。谁能帮我。输出文件根元素中的标记名称也会生成该类的包名称。

您可能可以使用split()来分别处理csv记录中的每一行。

from(SOURCE_INPUT_PATH).
 .split().tokenize(System.lineSeparator())
   unmarshal(bindyFixed).
   marshal().
   xstream().
   to(SOURCE_OUTPUT_PATH).log("Finished Transformation").end();
