我有一个Jackson可序列化对象，它包含了下面几层的其他对象。在某些情况下（可以用@JsonSerialize注解），我想更改该内部对象的序列化。我似乎不知道如何做到这一点。
在下面的示例中，整个Foo对象Request1通过默认序列化进行序列化，但在Request2中，Foo的所有示例都使用自定义序列化程序进行序列化。
请求1 JSON：

{
    id: "8c88e31c-f6da-4ce5-8c75-3cacd5cb6694",
    pojo: {
        foo: {
            value1: "abc",
            value2: "def"
        },
        bar: {
            other: {
                value1: "uvw",
                value2: "xyz"
            }
        }
    }
}

请求2 JSON：

{
    id: "8c88e31c-f6da-4ce5-8c75-3cacd5cb6694",
    pojo: {
        foo: [
            "abc",
            "def"
        ],
        bar: {
            other: [
                "uvw",
                "xyz"
            ]
        }
    }
}

Request1.java:

public class Request1 {
    private UUID id;
    private MyPojo pojo;
}

型
Request2.java:

public class Request2 {
    private UUID id;

    @JsonSerialize(using = MyPojoSerializer.class)
    private MyPojo pojo;
}

MyPojo.java:

public class MyPojo {
    private Foo foo;
    private Bar bar;

    public static class Bar {
        private Foo other;
    }
}

Foo.java:

public class Foo {
    private String value1;
    private String value2;

用于MyPojo的串行器：

public class MyPojoSerializer extends JsonSerializer<MyPojo> {

    @Override
    public void serialize(final MyPojo value, final JsonGenerator gen,
            final SerializerProvider serializers) throws IOException {
       
        // how to set custom serializer for Foo before serializing the MyPojo object???

        gen.writeObject(value);
    }

    private static class FooSerializer extends JsonSerializer<Foo> {
        @Override
        public void serialize(final Foo value, final JsonGenerator gen,
                final SerializerProvider serializers) throws IOException {
            gen.writeStartArray();
            gen.writeString(value.getValue1());
            gen.writeString(value.getValue2());
            gen.writeEndArray();
        }
    }
}
