jackson2.1.4反 序列化对象

public class User {

	private int id;
	
	private Date birthday;

	private double money;

	private String name;
}

{"id":1,"birthday":1365512156293,"money":0.0,"name":"JACK","age": 15}
当反序列化时 有多余的属性(age)会报错
//通过如下配置解决
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

mapper.addHandler(new DeserializationProblemHandler() {
			@Override
			public boolean handleUnknownProperty(DeserializationContext ctxt,
					JsonParser jp, JsonDeserializer<?> deserializer,
					Object beanOrClass, String propertyName)
					throws IOException, JsonProcessingException {
				if(propertyName == "age") {
					return true;
				}
				return false;
			}
	});
//也可以通过这种方式进行全局设置,在反序列化时会把user当中没有的属性(age)传递进来进行处理

	//或者
	@JsonAnySetter
	public void handleUnknown(String key, Object value) {
		// do something: put to a Map; log a warning, whatever
		 System.out.println(key + "---" + value.getClass());
	}

//也可以用注释对具体的类进行设置
@JsonIgnoreProperties(ignoreUnknown=true)
public class User
