1.引入需要的jar包，在pom.xml中配置依赖
Java代码
<dependency> <groupId>com.thoughtworks.xstream</groupId> <artifactId>xstream</artifactId> <version>
1.4.
2</version> </dependency>
<dependency>
<groupId>com.thoughtworks.xstream</groupId>
<artifactId>xstream</artifactId>
<version>1.4.2</version>
</dependency>
2.创建要转换的实例类，本文以简单的硬件信息为例
Java代码
package com.ajita.xstream;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamAsAttribute;
@XStreamAlias(
"DiskInfo")
public class DiskInfo {
@XStreamAsAttribute @XStreamAlias(
"diskName")
private String name;
private int totalSize;
private int avilableSize;
private int usedSize;
public String getName() {
return name; }
public void setName(String name) {
this.name = name; }
public int getTotleSize() {
return totalSize; }
public void setTotleSize(
int totleSize) {
this.totalSize = totleSize; }
public int getAvilableSize() {
return avilableSize; }
public void setAvilableSize(
int avilableSize) {
this.avilableSize = avilableSize; }
public int getUserSize() {
return usedSize; }
public void setUserSize(
int userSize) {
this.usedSize = userSize; }
public String toString() { StringBuilder sb =
new StringBuilder(); sb.append(name +
"\r\n"); sb.append(
"TotalSize:" + totalSize +
"|Used Size:" + usedSize +
"|Available Size:" + avilableSize);
return sb.toString(); } }
package com.ajita.xstream;
import java.util.List;
import com.thoughtworks.xstream.annotations.XStreamAlias;
@XStreamAlias(
"HardwareInfo")
public class HardwareInfo {
private String cpuInfo;
private String networkInfo;
private List<DiskInfo> diskInfos;
public String getCpuInfo() {
return cpuInfo; }
public void setCpuInfo(String cpuInfo) {
this.cpuInfo = cpuInfo; }
public String getNetworkInfo() {
return networkInfo; }
public void setNetworkInfo(String networkInfo) {
this.networkInfo = networkInfo; }
public List<DiskInfo> getDiskInfos() {
return diskInfos; }
public void setDiskInfos(List<DiskInfo> diskInfos) {
this.diskInfos = diskInfos; }
public String toString() { StringBuilder sb =
new StringBuilder(); sb.append(cpuInfo); sb.append(
"\r\n"); sb.append(networkInfo); sb.append(
"\r\n");
for (DiskInfo disk : diskInfos) { sb.append(disk.toString()); sb.append(
"\r\n"); }
return sb.toString(); } }
package com.ajita.xstream;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamAsAttribute;
@XStreamAlias("DiskInfo")
public class DiskInfo {
@XStreamAsAttribute
@XStreamAlias("diskName")
private String name;
private int totalSize;
private int avilableSize;
private int usedSize;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getTotleSize() {
return totalSize;
}
public void setTotleSize(int totleSize) {
this.totalSize = totleSize;
}
public int getAvilableSize() {
return avilableSize;
}
public void setAvilableSize(int avilableSize) {
this.avilableSize = avilableSize;
}
public int getUserSize() {
return usedSize;
}
public void setUserSize(int userSize) {
this.usedSize = userSize;
}
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append(name + "\r\n");
sb.append("TotalSize:" + totalSize + "|Used Size:" + usedSize
+ "|Available Size:" + avilableSize);
return sb.toString();
}
}
package com.ajita.xstream;
import java.util.List;
import com.thoughtworks.xstream.annotations.XStreamAlias;
@XStreamAlias("HardwareInfo")
public class HardwareInfo {
private String cpuInfo;
private String networkInfo;
private List<DiskInfo> diskInfos;
public String getCpuInfo() {
return cpuInfo;
}
public void setCpuInfo(String cpuInfo) {
this.cpuInfo = cpuInfo;
}
public String getNetworkInfo() {
return networkInfo;
}
public void setNetworkInfo(String networkInfo) {
this.networkInfo = networkInfo;
}
public List<DiskInfo> getDiskInfos() {
return diskInfos;
}
public void setDiskInfos(List<DiskInfo> diskInfos) {
this.diskInfos = diskInfos;
}
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append(cpuInfo);
sb.append("\r\n");
sb.append(networkInfo);
sb.append("\r\n");
for (DiskInfo disk : diskInfos) {
sb.append(disk.toString());
sb.append("\r\n");
}
return sb.toString();
}
}
3.新建测试代码
Java代码
package com.ajita.xstream;
import java.util.ArrayList;
import com.thoughtworks.xstream.XStream;
public class TestXStream {
public static void main(String[] args) { DiskInfo disk1 =
new DiskInfo(); disk1.setName(
"D:\\"); disk1.setTotleSize(
100); disk1.setUserSize(
20); disk1.setAvilableSize(
80); DiskInfo disk2 =
new DiskInfo(); disk2.setName(
"E:\\"); disk2.setTotleSize(
200); disk2.setUserSize(
40); disk2.setAvilableSize(
160); ArrayList<DiskInfo> diskInfos =
new ArrayList<DiskInfo>(); diskInfos.add(disk1); diskInfos.add(disk2); HardwareInfo hwInfo =
new HardwareInfo(); hwInfo.setCpuInfo(
"cpu info is ..."); hwInfo.setNetworkInfo(
"network info is ..."); hwInfo.setDiskInfos(diskInfos); XStream xStream =
new XStream(); xStream.autodetectAnnotations(
true); String xml = xStream.toXML(hwInfo); System.out.println(xml); HardwareInfo info2 = (HardwareInfo) xStream.fromXML(xml); System.out.println(info2); } }
package com.ajita.xstream;
import java.util.ArrayList;
import com.thoughtworks.xstream.XStream;
public class TestXStream {
/**
* @param args
*/
public static void main(String[] args) {
DiskInfo disk1 = new DiskInfo();
disk1.setName("D:\\");
disk1.setTotleSize(100);
disk1.setUserSize(20);
disk1.setAvilableSize(80);
DiskInfo disk2 = new DiskInfo();
disk2.setName("E:\\");
disk2.setTotleSize(200);
disk2.setUserSize(40);
disk2.setAvilableSize(160);
ArrayList<DiskInfo> diskInfos = new ArrayList<DiskInfo>();
diskInfos.add(disk1);
diskInfos.add(disk2);
HardwareInfo hwInfo = new HardwareInfo();
hwInfo.setCpuInfo("cpu info is ...");
hwInfo.setNetworkInfo("network info is ...");
hwInfo.setDiskInfos(diskInfos);
XStream xStream = new XStream();
xStream.autodetectAnnotations(true);
String xml = xStream.toXML(hwInfo);
System.out.println(xml);
HardwareInfo info2 = (HardwareInfo) xStream.fromXML(xml);
System.out.println(info2);
}
}
输出如下：
Java代码
<HardwareInfo> <cpuInfo>cpu info is ...</cpuInfo> <networkInfo>network info is ...</networkInfo> <diskInfos> <DiskInfo diskName=
"D:\"> <totalSize>
100</totalSize> <avilableSize>

cpu info is ...
network info is ...
D:\

E:\

4.常用XStream注解
1）@XStreamAlias注解可在类与属性上使用设置名称,相当于: xstream.alias("blog", Blog.class);
2）@XStreamImplicit去集合节点名:相当于 xstream.addImplicitCollection(Blog.class, "entries");
3） @XStreamConverter(SingleValueCalendarConverter.class)
private Calendar createdTime = new GregorianCalendar();
