java – 以编程方式更改JsonProperty(Access.WRITE_ONLY)

使用fasterXML创建过滤器,并定义要过滤的字段.可以使用硬编码定义属性列表,也可以在运行时计算属性列表.
例如,在admin控制器中,过滤器列表为空(或部分),而常规控制器过滤器列表包含值：
您要序列化的类：

@JsonFilter("PersonFilter")
public class Person
{
   private List<Integer> integerList; 
   private Integer creditCardNUmber;
   private String firstName;
   private String lastName;

public static FilterProvider getFilter(){
    Set<String> fieldsToFilter= new HashSet<>(Arrays.asList("creditCardNUmber","integerList");
    SimpleBeanPropertyFilter theFilter = SimpleBeanPropertyFilter
            .serializeAllExcept(fieldsToFilter);
    FilterProvider filters = new SimpleFilterProvider()
            .addFilter("PersonFilter",theFilter);
    return filters;
}
}

序列化对象时,可以使用预定义的属性列表进行过滤(public static FilterProvider getFilter(){..}),或者在运行时定义它们.

public static String GetObjectAsStringWithFilter(FilterProvider filters,Object jsonObject)
{
    if (jsonObject == null)
    {
        return null;
    }
    String objectAsString = null;
    try
    {
        objectAsString = objectMapper.writer(filters).writeValueAsString(jsonObject);
    }
    catch (Exception e)
    {
        ...
    }

    return objectAsString;
}
