提供Redisson的Codec

[tywo45]

请描述您的需求或者改进建议

对比过几大顶流序列化框架，FastJson的JSONB性能非常优异，想在redisson中使用FastJson的JSONB作为Codec

请描述你建议的实现方案

实现Redisson的接口Codec

描述您考虑过的替代方案

除了自己实现Codec，也可以和Redisson的开发人员沟通，让Redisson实现FastJson版的Redisson的Codec

已经支持，请帮忙用2.0.49-SNAPSHOT版本验证，2.0.49版本预计在明天（4月14日）发布

• Maven依赖

<dependency>
    <groupId>com.alibaba.fastjson2</groupId>
    <artifactId>fastjson2-extension</artifactId>
    <version>2.0.49-SNAPSHOT</version>
</dependency>

• 示例代码

    @Test
    public void json() throws Exception {
        JSONCodec codec = new JSONCodec(Bean.class);

        Bean bean = new Bean();
        bean.name = "abc";

        ByteBuf encoded = codec.getValueEncoder()
                .encode(bean);

        Bean decoded = (Bean) codec.getValueDecoder().decode(encoded, null);
        assertEquals(bean.name, decoded.name);
    }

    @Test
    public void jsonAutoType() throws Exception {
        JSONCodec codec = new JSONCodec(
                JSONFactory.createWriteContext(JSONWriter.Feature.WriteClassName),
                JSONFactory.createReadContext(JSONReader.autoTypeFilter(Bean.class))
        );

        Bean bean = new Bean();
        bean.name = "abc";

        ByteBuf encoded = codec.getValueEncoder()
                .encode(bean);

        Bean decoded = (Bean) codec.getValueDecoder().decode(encoded, null);
        assertEquals(bean.name, decoded.name);
    }

    @Test
    public void jsonb() throws Exception {
        JSONBCodec codec = new JSONBCodec(Bean.class);

        Bean bean = new Bean();
        bean.name = "abc";

        ByteBuf encoded = codec.getValueEncoder()
                .encode(bean);

        Bean decoded = (Bean) codec.getValueDecoder().decode(encoded, null);
        assertEquals(bean.name, decoded.name);
    }

    @Test
    public void jsonbAutoType() throws Exception {
        JSONBCodec codec = new JSONBCodec(
                JSONFactory.createWriteContext(JSONWriter.Feature.WriteClassName),
                JSONFactory.createReadContext(JSONReader.autoTypeFilter(Bean.class))
        );

        Bean bean = new Bean();
        bean.name = "abc";

        ByteBuf encoded = codec.getValueEncoder()
                .encode(bean);

        Bean decoded = (Bean) codec.getValueDecoder()
                .decode(encoded, null);
        assertEquals(bean.name, decoded.name);
    }

    public static class Bean {
        public String name;
    }

其中autoType的例子，为了避免自动类型带来的安全问题，手动配置JSONReader.autoTypeFilter是配置自动类型支持的类名前缀，参考
