JsonConfig config = new JsonConfig();
config.setIgnoreDefaultExcludes(false);
config.setCycleDetectionStrategy(CycleDetectionStrategy.LENIENT);
config.registerJsonValueProcessor(Date.class,new DateJsonValueProcessor("yyyy-MM-dd")); //date processor register
config.setExcludes(new String[]{//只要設(shè)置這個數(shù)組，指定過濾哪些字段。
"consignee",
"contract",
"coalInfo",
"coalType",
"startStation",
"balanceMan",
"endStation"
});

2.設(shè)置JSON-LIB的setCycleDetectionStrategy屬性讓其自己處理循環(huán)，省事但是數(shù)據(jù)過于復(fù)雜的話會引起數(shù)據(jù)溢出或者效率低下。
