json转java的Bean和Bean转json时Date时间处理

2019独角兽企业重金招聘Python工程师标准>>>

准备工作：

json-2.4.jar

ezmorph-1.0.6.jar

类

public class JsonDateValueProcessor implements JsonValueProcessor {
    private String datePattern = "yyyy-MM-dd";

    public JsonDateValueProcessor() {
        super();
    }

    public JsonDateValueProcessor(String format) {
        super();
        this.datePattern = format;
    }

    @Override
    public Object processArrayValue(Object value, JsonConfig jsonConfig) {
        return process(value);
    }

    @Override
    public Object processObjectValue(String key, Object value,
            JsonConfig jsonConfig) {
        return process(value);
    }

    private Object process(Object value) {
        try {
            if (value instanceof Date) {
                SimpleDateFormat sdf = new SimpleDateFormat(datePattern,
                        Locale.UK);
                return sdf.format((Date) value);
            }
            return value == null ? "" : value.toString();
        } catch (Exception e) {
            return "";
        }

    }

    public String getDatePattern() {
        return datePattern;
    }

    public void setDatePattern(String pDatePattern) {
        datePattern = pDatePattern;
    }
}

1.json转bean

String[] dateFmts = new String[] { "yyyy/MM/dd", "yyyy-MM-dd HH:mm:ss" };  
（没有时分秒去HH:mm:ss掉即可）
JSONUtils.getMorpherRegistry().registerMorpher( new DateMorpher(dateFmts));
ReportRfid rr = (ReportRfid)JSONObject.toBean(JSONObject,ReportRfid.class);

2.bean转json

JsonConfig jsonConfig = new JsonConfig();  
jsonConfig.registerJsonValueProcessor(Date.class , new JsonDateValueProcessor());
JSONArray tempJsonArray = JSONArray.fromObject(tempList,jsonConfig);
单个bean同上
