JSONField 定义在抽象类中，对子类不起作用。

abstract class B {
    private String id;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    @JSONField(serialize = false, deserialize = false)
    public abstract String getName();

}

class C extends B {
    private String c;

    private String name;

    public String getC() {
        return c;
    }

    public void setC(String c) {
        this.c = c;
    }

    @Override
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

 public void test() {

        LoanContractVO loanContractVO = new LoanContractVO();

        C c = new C();
        c.setId("22222222222");
        c.setName("name");
        c.setC("dddddddddddddddddd");

        String json = JSON.toJSONString(c);

        JSONObject obj = JSON.parseObject(json);

        System.out.println(json);
    }

结果：
{"c":"dddddddddddddddddd","id":"22222222222","name":"name"}

期望结果：
{"c":"dddddddddddddddddd","id":"22222222222"}
