JAXB返回null

标签: java xml jaxb

我已经阅读了几个JAXB教程,并尝试实现自己的教程。我回来了。我不确定为什么我会变空。 这是我的XML文档。我很抱歉这篇文章的主要代码有多长。我只是不确定我是否正确实现JAXB。

这是我的运行类来解组我的xml。

import java.io.File;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;

import com.interpro.Objects.*;
public class run {

/**
 * @param args
 */
public static void main(String[] args) {
    try {

        File file = new File("C:/Development/workspace/com.interpro.xml/src/XML/offlineconfig.xml");
        JAXBContext jaxbContext = JAXBContext.newInstance(EZMAXMOBILE_OFFLINE_PROPERTIES.class);

        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        EZMAXMOBILE_OFFLINE_PROPERTIES emm = (EZMAXMOBILE_OFFLINE_PROPERTIES) jaxbUnmarshaller.unmarshal(file);
        System.out.println();

      } catch (JAXBException e) {
        e.printStackTrace();
      }


}

}

以下是我生成的一些课程。

package com.interpro.Objects;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
@XmlRootElement(name = "EZMAXMOBILE_OFFLINE_PROPERTIES")
@XmlType(propOrder = {"entity_defs", "selection_defs", "tx_settings", "offline_file_cache"})
public class EZMAXMOBILE_OFFLINE_PROPERTIES {
private String synctime;
private ENTITY_DEFS entity_defs;
public ENTITY_DEFS getEntity_defs() {
    return entity_defs;
}
@XmlElement
public void setEntity_defs(ENTITY_DEFS entity_defs) {
    this.entity_defs = entity_defs;
}

public SELECTION_DEFS getSelection_defs() {
    return selection_defs;
}
@XmlElement
public void setSelection_defs(SELECTION_DEFS selection_defs) {
    this.selection_defs = selection_defs;
}

public TX_SETTINGS getTx_settings() {
    return tx_settings;
}
@XmlElement
public void setTx_settings(TX_SETTINGS tx_settings) {
    this.tx_settings = tx_settings;
}

public OFFLINE_FILE_CACHE getOffline_file_cache() {
    return offline_file_cache;
}
@XmlElement
public void setOffline_file_cache(OFFLINE_FILE_CACHE offline_file_cache) {
    this.offline_file_cache = offline_file_cache;
}

private SELECTION_DEFS selection_defs;
private TX_SETTINGS tx_settings;
private OFFLINE_FILE_CACHE offline_file_cache;

public String getSynctime() {
    return synctime;
}
@XmlAttribute
public void setSynctime(String synctime) {
    this.synctime = synctime;
}

} EZMAXMOBILE_OFFLINE_PROPERTIES类应生成Entity_defs对象

package com.interpro.Objects;

import java.util.ArrayList;

import javax.xml.bind.annotation.XmlElement;

public class ENTITY_DEFS {
private ArrayList<ENTITY> entitylist;

public ArrayList<ENTITY> getEntitylist() {
    return entitylist;
}
@XmlElement
public void setEntitylist(ArrayList<ENTITY> entitylist) {
    this.entitylist = entitylist;
}

} 然后在ENTITY_DEFS内部,它应该列出ENTITY对象。

package com.interpro.Objects;

import java.util.ArrayList;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;

public class ENTITY {
private String name;

public String getName() {
    return name;
}@XmlAttribute
public void setName(String name) {
    this.name = name;
}

private INDEXES indexes;

public INDEXES getIndexes() {
    return indexes;
}@XmlElement
public void setIndexes(INDEXES indexes) {
    this.indexes = indexes;
}

public COLUMNS getColumns() {
    return columns;
}@XmlElement
public void setColumns(COLUMNS columns) {
    this.columns = columns;
}

public INIT_ACTION getInit_action() {
    return init_action;
}@XmlElement
public void setInit_action(INIT_ACTION init_action) {
    this.init_action = init_action;
}

public DELTA_ACTION getDelta_action() {
    return delta_action;
}@XmlElement
public void setDelta_action(DELTA_ACTION delta_action) {
    this.delta_action = delta_action;
}

public SYNC_ACTION getSync_action() {
    return sync_action;
}@XmlElement
public void setSync_action(SYNC_ACTION sync_action) {
    this.sync_action = sync_action;
}

private COLUMNS columns;
private INIT_ACTION init_action;
private DELTA_ACTION delta_action;
private SYNC_ACTION sync_action;

}

您可以填充对象模型,然后编组它以了解JAXB当前期望的XML输入。快速浏览一下您的模型,您至少需要以下内容:

  • 使用@XmlElement注释指定要映射到的元素名称,因为基于您的字段/属性的默认名称不匹配。
  • 由于您的馆藏中包含分组元素,因此您可以使用@XmlElementWrapper注释。
