xstream ——---json_xstream jettisonmappedxmldriver jsonhierarchicalst-优快云博客

本文介绍如何使用XStream库将Java对象转换为JSON格式。通过实例演示了配置XStream来支持JSON输出的方法，包括设置输出模式和别名。

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。

package com.xstream.demo1;

import java.io.Writer;
import java.util.ArrayList;
import java.util.List;

import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.HierarchicalStreamWriter;
import com.thoughtworks.xstream.io.json.JsonHierarchicalStreamDriver;
import com.thoughtworks.xstream.io.json.JsonWriter;
import com.xstream.vo1.Address;
import com.xstream.vo1.Addresses;

public class XstreamJsonDemo {
   public static void main(String args[]){
       XstreamJsonDemo tester = new XstreamJsonDemo();
       XStream xstream = new XStream(new JsonHierarchicalStreamDriver() {
            public HierarchicalStreamWriter createWriter(Writer writer) {
                return new JsonWriter(writer, JsonWriter.DROP_ROOT_MODE);
            }

       });

       List<Address> list = new ArrayList<Address>();
       Address address1 = new Address("t1", "p1");
       Address address2 = new Address("t2", "p2");
       list.add(address1);
       list.add(address2);
       Addresses addresses = new Addresses(list);


       xstream.setMode(XStream.NO_REFERENCES);
        xstream.alias("addresses", Addresses.class);

        System.out.println(xstream.toXML(addresses));

   }
