复现case如下：用 1.2.69 和 1.2.83 版本的 fastjson 会得出不同的结果

import com.alibaba.fastjson.annotation.JSONField;

    @Data
    public static class SomeModel {
        private String id;
        @JSONField(name = "some_value")
        private int someValue;
    }

    /**

* fastjson 1.2.69 即使标注了 JSONField, 仍然会用 propertyName 解析注入
* 但是 fastjson 1.2.83 只会根据 JSONField  声明的 field 注入

    @Test
    void testFastJson1() {
        String json1 = "{\"id\":\"135951990146386429\",\"someValue\":1}";
        SomeModel dto1 = JSON.parseObject(json1, SomeModel.class);
        Assertions.assertEquals(0, dto1.someValue);
    }

    @Test
    void testFastJson2() {
        String json1 = "{\"id\":\"135951990146386429\",\"some_value\":1}";
        SomeModel dto1 = JSON.parseObject(json1, SomeModel.class);
        Assertions.assertEquals(1, dto1.someValue);
