时间格式的时间 转json的时候变成正常的string时间20170519

public class JsonDateValueProcessor implements JsonValueProcessor {    private String format ="yyyyMMdd";

public JsonDateValueProcessor() {        super();    }

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

@Override    public Object processArrayValue(Object paramObject,                                    JsonConfig paramJsonConfig) {        return process(paramObject);    }

@Override    public Object processObjectValue(String paramString, Object paramObject,                                     JsonConfig paramJsonConfig) {        return process(paramObject);    }

private Object process(Object value){        if(value instanceof Date){            SimpleDateFormat sdf = new SimpleDateFormat(format, Locale.CHINA);            return sdf.format(value);        }        return value == null ? "" : value.toString();    }}

controller里这样写

List<T> list = service.queryFromWtxs();   //查询到要显示的实体类表JsonConfig jsonConfig = new JsonConfig();jsonConfig.registerJsonValueProcessor(Date.class, new JsonDateValueProcessor());JSONArray jsonArray22=JSONArray.fromObject(list,jsonConfig);        //实体类表转成json；时间变转换器里的时间格式sum = list.size();mv.addObject("list",jsonArray22);        //在jsp使用“list”
