Java对象序列化/反序列化为JSON/XML格式

//Java对象序列化为JSON格式（需引入jackson-all-1.7.6.jar）
Person person = new Person();

String personJson = null;
ObjectMapper mapper = new ObjectMapper();
StringWriter sw = new StringWriter();
JsonGenerator gen = new JsonFactory().createJsonGenerator();
mapper.writeValue(gen, person);
gen.close();

personJson = sw.toString();

//JSON反序列化
Person zhansan = (Person)mapper.readValue(personJson, Person.class);


//Java对象序列化为XML格式（需引入xstream-1.4.4.jar）
Person person = new Person();

XStream xStream = new XStream(new DomDriver());
xStream.alias("person", Person.class);

String personXML = xStream.toXML(person);

//XML反序列化
Person zhangsan = (Person)xStream.fromXML(personXML);
