    @Bean
    public ResourceConfig resourceConfig() {
        ResourceConfig resourceConfig = new ResourceConfig();

        // 用FastJson替换掉默认的Jackson
        resourceConfig.register(FastJsonResolver.class);
        resourceConfig.register(FastJsonFeature.class);

        return resourceConfig;
    }

    @Provider
    static class FastJsonResolver implements ContextResolver<FastJsonConfig> {
        // 用FastJson替换掉默认的Jackson
        public FastJsonConfig getContext(Class<?> type) {
            FastJsonConfig fastJsonConfig = new FastJsonConfig();
            return fastJsonConfig;
        }
