问题描述

序列化时如果指定了Filters,IgnoreGetterError配置不起作用

环境信息

请填写以下信息:

  • OS信息: [e.g.:任何版本]
  • JDK信息: [e.g.:任何版本]
  • 版本信息:[e.g.:Fastjson2 2.0.6]

重现步骤

JSON.toJSONString(obj, dateFormat, defaultSerializeFilters, serializeFeatures);
其中:defaultSerializeFilters指定了一个ValueFilter和一个NameFilter;
serializeFeatures如下:
JSONWriter.Feature[] serializeFeatures = {
/* 序列化enum使用name /
JSONWriter.Feature.WriteEnumsUsingName,
/
序列化BigDecimal使用toPlainString,避免科学计数法*/
JSONWriter.Feature.WriteBigDecimalAsPlain,
/* 忽略getter方法异常 */
JSONWriter.Feature.IgnoreErrorGetter,
};
测试代码:

       DataVO3 d = new DataVO3();
		d.setV(localDateTime);
    	String json = JSON.toJSONString(d, "yyyy-MM-dd HH:mm:ss", defaultSerializeFilters, serializeFeatures);

	static class DataVO3 {
		LocalDateTime v;

		public LocalDateTime getV() {
			throw new RuntimeException("mock an exception");
		}
		public void setV(LocalDateTime v) {
			this.v = v;
		}
	}

期待的正确结果

对您期望发生的结果进行清晰简洁的描述。
