Question

我在这里从互联网上获取了一系列货币：http://dnb.no/portalfront/datafiles/miscellaneous/csv/kursliste_ws.xml

现在我想把它变成一个Java对象，所以我可以用它来做。我正在尝试使用jaxbUnmarshal，但我对任何事情持开放态度。

package com.domain.subdomain.routes;

import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.dataformat.JaxbDataFormat;

public class CurrencyRoute extends RouteBuilder {


    private String currencyWsURL; // http://dnb.no/portalfront/datafiles/miscellaneous/csv/kursliste_ws.xml from Spring template

    @Override
    public void configure() {
        from("quartz://myTimer?trigger.repeatCount=0")
                .log("### Quartz trigger ###")
                .to("direct:readFile");

        from("direct:readFile")
                .log("### Read file ###")
                .to("https4://" + currencyWsURL)
                .to("dataformat:jaxb:unmarshal")
                .log("${body}");
    }

    public void setCurrencyWsURL(String currencyWsURL) {
        this.currencyWsURL = currencyWsURL;
    }
}

我创建了一个名为Currency的Java对象：

package com.domain.subdomain.domain;

public class Currency {
    String country;
    String isoCode;
    String code;
    Double unit;
    String name;

    Double transferPurcase;
    Double transferSell;
    Double transferChanges;
    Double transferPrevious;
    Double transferMiddleCourse;

    Double notePurcase;
    Double noteSell;

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    public String getIsoCode() {
        return isoCode;
    }

    public void setIsoCode(String isoCode) {
        this.isoCode = isoCode;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public Double getUnit() {
        return unit;
    }

    public void setUnit(Double unit) {
        this.unit = unit;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Double getTransferPurcase() {
        return transferPurcase;
    }

    public void setTransferPurcase(Double transferPurcase) {
        this.transferPurcase = transferPurcase;
    }

    public Double getTransferSell() {
        return transferSell;
    }

    public void setTransferSell(Double transferSell) {
        this.transferSell = transferSell;
    }

    public Double getTransferChanges() {
        return transferChanges;
    }

    public void setTransferChanges(Double transferChanges) {
        this.transferChanges = transferChanges;
    }

    public Double getTransferPrevious() {
        return transferPrevious;
    }

    public void setTransferPrevious(Double transferPrevious) {
        this.transferPrevious = transferPrevious;
    }

    public Double getTransferMiddleCourse() {
        return transferMiddleCourse;
    }

    public void setTransferMiddleCourse(Double transferMiddleCourse) {
        this.transferMiddleCourse = transferMiddleCourse;
    }

    public Double getNotePurcase() {
        return notePurcase;
    }

    public void setNotePurcase(Double notePurcase) {
        this.notePurcase = notePurcase;
    }

    public Double getNoteSell() {
        return noteSell;
    }

    public void setNoteSell(Double noteSell) {
        this.noteSell = noteSell;
    }
}

当我运行代码时，我收到此错误：

java.lang.IllegalArgumentException：无法找到名称为的数据格式： JAXB

首先对不起我的简短回答，但我正在通过我的手机写作。

但是这里有我的项目，我做这样的事情，请看，我希望它可以帮到你。

https://github.com/vtripeno/integration_camel_apis/blob/master/Camel/src/main/java/br/com/camel/integration/credit/user/routes/IntegrationRoute.java

你可以在POJO中做这样的事情：

@ApiModel(description = "The Credit contract.")
@Validated
@XmlRootElement(name = "root_element")
@XmlAccessorType(XmlAccessType.FIELD)
public class POJO implements Serializable {

@JsonProperty("data")
@ApiModelProperty(value = "The credit proposal object")
private Stirng data;
// GETTER AND SETTER
}

你只需要在邮件标题'Content-Type = application / xml'中发送send，它就可以了。但是，如果你想用XML转换你的POJO，你需要做这样的事情：

@Component
public class IntegrationRoute extends RouteBuilder {
@Override
public void configure() throws Exception {

    XmlJsonDataFormat xmlJsonFormat = new XmlJsonDataFormat();
    xmlJsonFormat.setForceTopLevelObject(true);
    xmlJsonFormat.setEncoding("UTF-8");
    xmlJsonFormat.setForceTopLevelObject(true);
    xmlJsonFormat.setTrimSpaces(true);
    xmlJsonFormat.setRootName("data");
    xmlJsonFormat.setSkipNamespaces(true);
    xmlJsonFormat.setRemoveNamespacePrefixes(true);
    xmlJsonFormat.setExpandableProperties(Arrays.asList("d", "e"));
from("direct:your_route").id("yourRoute")
        .unmarshal(xmlJsonFormat)
        .to("log:end")
        .end();
}

如何在Apache驼峰中将XML转换为Java对象？
