Jackson 转json 时日期格式化，排除字段，包含字段

package com.dj.spring3.jackson;
import org.codehaus.jackson.map.SerializationConfig;
import org.codehaus.jackson.map.introspect.BasicBeanDescription;
import org.codehaus.jackson.map.ser.BeanSerializerFactory;


/**

public class BidBeanSerializerFactory extends BeanSerializerFactory {


    public final static BidBeanSerializerFactory instance = new BidBeanSerializerFactory(null);
    
    private Object filterId;
    
protected BidBeanSerializerFactory(Config config) {
super(config);
}

    @Override
    protected Object findFilterId(SerializationConfig config,
    BasicBeanDescription beanDesc) {
    return getFilterId();
    }


public Object getFilterId() {
return filterId;
}


public void setFilterId(Object filterId) {
this.filterId = filterId;
}
}

=======测试代码======================

* @throws Exception
*/
public static void main(String[] args) throws Exception {

ObjectMapper objectMapper = new ObjectMapper();

//排除
SimpleFilterProvider fileter = new SimpleFilterProvider();
fileter.addFilter(
"executeFilter",

 "quality" }));
objectMapper.setFilters(fileter);

//仅包含
// SimpleFilterProvider fileter2 = new SimpleFilterProvider();
// fileter2.addFilter(
// "includeFilter",
// SimpleBeanPropertyFilter.filterOutAllExcept(new String[] {

// objectMapper.setFilters(fileter2);

//设置日期格式化
objectMapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));

JsonGenerator generator = objectMapper.getJsonFactory()
.createJsonGenerator(System.out, encoding);
BidBeanSerializerFactory bidBeanFactory = BidBeanSerializerFactory.instance;
bidBeanFactory.setFilterId("executeFilter"); //如果是仅包含这里填写  includeFilter
objectMapper.setSerializerFactory(bidBeanFactory);
