XStream支持JSON通过初始化XStream对象适当的驱动程序。 XStream目前支持JettisonMappedXmlDriver和JsonHierarchicalStreamDriver。
现在,让我们使用XStream处理JSON的代码测试。
创建一个Java类名为XStreamTester文件在 C:\>XStream_WORKSPACE\cn\sxt\xstream.
File: XStreamTester.java
package cn.sxt.xstream;
import java.io.Writer;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.io.HierarchicalStreamWriter;
import com.thoughtworks.xstream.io.json.JsonHierarchicalStreamDriver;
import com.thoughtworks.xstream.io.json.JsonWriter;
public class XStreamTester {
public static void main(String args[]){
XStreamTester tester = new XStreamTester();
XStream xstream = new XStream(new JsonHierarchicalStreamDriver() {
public HierarchicalStreamWriter createWriter(Writer writer) {
return new JsonWriter(writer, JsonWriter.DROP_ROOT_MODE);
}
});
Student student = new Student("Mahesh","Parashar");
xstream.setMode(XStream.NO_REFERENCES);
xstream.alias("student", Student.class);
System.out.println(xstream.toXML(student));
}
}
@XStreamAlias("student")
class Student {
private String firstName;
private String lastName;
public Student(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public String toString(){
return "Student [ firstName: "+firstName+", lastName: "+ lastName+ " ]";
}
}
验证结果
使用javac编译器编译如下类:
C:\XStream_WORKSPACE\cn\sxt\xstream>javac XStreamTester.java
现在运行XStreamTester看到的结果:
C:\XStream_WORKSPACE\cn\sxt\xstream>java XStreamTester
验证输出
{
"firstName": "Mahesh",
"lastName": "Parashar"
}
