NameFilter

FASTJSON提供了一个序列化时对字段名做处理的扩展叫做NameFilter，接口如下

package com.alibaba.fastjson2.filter;

public interface NameFilter
        extends Filter {
    String process(Object object, String name, Object value);
}

NameFilter通过of方法提供了常见需求的实现，比如：

public class Bean {
    public int userId;
}

@Test
public void test() {
    Bean bean = new Bean();
    bean.userId = 101;

    NameFilter pascalNameFilter = NameFilter.of(PropertyNamingStrategy.PascalCase);
    String str = JSON.toJSONString(bean, pascalNameFilter);
    assertEquals("{\"UserId\":101}", str);
    JSONObject object = JSON.parseObject(str);
    assertEquals(101, object.get("UserId"));
}
