只要继承它的抽象类：public abstract class JsonSerializer<T>，并在相应的属性方法上添加指定注解：@JsonSerialize 即可实现。
编写Date日志自定义转换类：
CustomDateSerializer.java
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.codehaus.jackson.JsonGenerator;
import org.codehaus.jackson.JsonProcessingException;
import org.codehaus.jackson.map.JsonSerializer;
import org.codehaus.jackson.map.SerializerProvider;
public class CustomDateSerializer extends JsonSerializer<Date> {
@Override
public void serialize(Date value, JsonGenerator jgen,SerializerProvider provider)
throws IOException,JsonProcessingException {
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String formattedDate = formatter.format(value);
jgen.writeString(formattedDate);
}
}javabean对应get方法添加注解：
@JsonSerialize(using = CustomDateSerializer.class)
public Date getCreateDate() {
return createDate;
}
