我正在尝试将管道分隔的字符串转换为 xml，它工作正常。但是，我没有得到下面显示的实际输出。在我的输出中，父标签与包名一起生成，也没有生成我想要的命名空间。谁能帮助我如何将平面文件转换为我期望的确切输出。

CamelConfig.java

@Component
public class CamelConfig extends RouteBuilder {
    @Override
    public void configure() throws Exception {
        try {
            CamelContext context = new DefaultCamelContext();
            ConverterRoute route = new ConverterRoute();
            route.addRoutesToCamelContext(context);
            context.start();
            Thread.sleep(5000);
            context.stop();

        } catch (Exception exe) {
            exe.printStackTrace();
        }
    }
}

转换器路由.java

public class ConverterRoute implements RoutesBuilder {

    private static final String SOURCE_INPUT_PATH = "file://inbox?fileName=Source.txt";

    private static final String SOURCE_OUTPUT_PATH = "file://outbox?fileName=file.xml";

    public void addRoutesToCamelContext(CamelContext context) throws Exception {

        context.addRoutes(new RouteBuilder() {
            public void configure() {
                try {
                    DataFormat bindyFixed = new BindyCsvDataFormat(Test.class);

                    from(SOURCE_INPUT_PATH).
                            unmarshal(bindyFixed).
                            marshal().
                            xstream().
                            to(SOURCE_OUTPUT_PATH).log("Finished Transformation").end();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

测试.java

package com.john;
@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

测试.xml

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

预期产出

测试.xml

<?xml version='1.0' encoding='UTF-8'?>
    <Test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <ALT_NUM>55158</ALT_NUM>
            <PRTNUM>11901</PRTNUM>
            <UOMCOD>2346</UOMCOD>
    </Test>

aliases您可以使用dataformat 属性定义类型别名：

XStreamDataFormat xstream = new XStreamDataFormat();
xstream.setAliases(Collections.singletonMap("Test", Test.class.getCanonicalName()));
//...
.marshal(xstream)

为了在您的实体中定义自定义命名空间使用@XStreamAsAttribute和：@XStreamAlias

public class Test {
    @XStreamAsAttribute
    @XStreamAlias("xmlns:xsi")
    private final String xmlns = "http://www.w3.org/2001/XMLSchema-instance";
    //...
}
