测试场景1:

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONReader;

import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;
import lombok.ToString;

public class JSONTest {
	@Setter
	@Getter
	@NoArgsConstructor
	@AllArgsConstructor
	@ToString
	public static class TestVO{
		private String Ref;
		private Double Width;
		private Double High;
	}
	/**
	 * Fastjson默认读特性
	 */
	public static final JSONReader.Feature[] FASTJSON_DEFAULT_READER_FEATURES = {JSONReader.Feature.SupportSmartMatch, JSONReader.Feature.SupportArrayToBean, JSONReader.Feature.UseNativeObject, JSONReader.Feature.SupportClassForName,JSONReader.Feature.IgnoreSetNullValue,JSONReader.Feature.AllowUnQuotedFieldNames,JSONReader.Feature.IgnoreCheckClose,JSONReader.Feature.IgnoreAutoTypeNotMatch };
	
	public static void main(String[] args) {
		String json = "{\r\n"
				+ "	\"Ref\": \"\",\r\n"
				+ "	\"Width\": \"\",\r\n"
				+ "	\"High\": \"\"\r\n"
				+ "}";
//		String json = "{\"Ref\": \"\",\"Width\": \"\",\"High\": \"\"}";
		TestVO jsonRootBean = JSON.parseObject(json, TestVO.class, FASTJSON_DEFAULT_READER_FEATURES);
	     System.out.println(jsonRootBean);
	}
}

测试场景2:

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONReader;

import lombok.AllArgsConstructor;

	public static class TestVO{
		private String Ref;
		private Double Width;
		private Double High;
	}
	/**
	 * Fastjson默认读特性
	 */
	public static final JSONReader.Feature[] FASTJSON_DEFAULT_READER_FEATURES = {JSONReader.Feature.SupportSmartMatch, JSONReader.Feature.SupportArrayToBean, JSONReader.Feature.UseNativeObject, JSONReader.Feature.SupportClassForName,JSONReader.Feature.IgnoreSetNullValue,JSONReader.Feature.AllowUnQuotedFieldNames,JSONReader.Feature.IgnoreCheckClose,JSONReader.Feature.IgnoreAutoTypeNotMatch };
	
	public static void main(String[] args) {
		String json = "{\r\n"
				+ "	\"Ref\": \"\",\r\n"
				+ "	\"Width\": \"\",\r\n"
				+ "	\"High\": \"\""
				+ "}";
//		String json = "{\"Ref\": \"\",\"Width\": \"\",\"High\": \"\"}";
		TestVO jsonRootBean = JSON.parseObject(json, TestVO.class, FASTJSON_DEFAULT_READER_FEATURES);
	     System.out.println(jsonRootBean);
	}
}
