Class_Level_SerializeFilter

对于框架来说，如果在toJSONString的时候，传入SerializeFilter，会导致对所有的类型做过滤，性能会受到一定影响。在1.2.10版本之后，fastjson提供类级别的SerializeFilter支持。

Support Version

1.2.10 and later

Interface

packagecom.alibaba.fastjson.serializer;
publicclassSerializeConfig {
publicvoidaddFilter(Class<?> clazz, SerializeFilterfilter);
}

Sample

publicclassClassNameFilterTestextendsTestCase {
publicvoidtest_filter() throwsException {
NameFilterupcaseNameFilter = newNameFilter() {
publicStringprocess(Objectobject, Stringname, Objectvalue) {
returnname.toUpperCase();
}
};
SerializeConfig.getGlobalInstance() //
.addFilter(A.class, upcaseNameFilter);
Assert.assertEquals("{\"ID\":0}", JSON.toJSONString(newA()));
Assert.assertEquals("{\"id\":0}", JSON.toJSONString(newB()));
}
publicstaticclassA {
publicintid;
}
publicstaticclassB {
publicintid;
}
