问题： 当我在使用Getway时，我将uri写为 http://localhost:xxx的形式是可以正确转发到我的服务中的 但是我如果使用，uri: lb://cloud-uim 带上服务名称的话，就会出现已下的异常内容 我已经检查过我的，spring.application.name 是和要转发的服务名"cloud-uim" 一致的，麻烦大佬们帮我查看一下呢谢谢！

异常内容为： java.lang.NullPointerException: null at java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936) Suppressed: reactor.core.publisher.FluxOnAssembly$OnAssemblyException: Error has

Fix issue1866.

fastjson1.x:移除了key和value fastjson2.0.40:仅移除了value

能提供重现问题的testcase么？

FASTJSON 2.0.x has been released, faster and more secure, recommend you upgrade.

像下面这个代码，为什么没有打印出：{"a":0,"b":0,"c":"1"}

public class XxxxTest {
    public static void main(String[] args){
        ObjectWriterProvider writerProvider = new ObjectWriterProvider();
        writerProvider.register(Long.class, (out, obj, fieldName, fieldType, features) -> {
            out.writeString(String.valueOf(obj));
        });

        JSONWriter.Context writeContext = new JSONWriter.Context(writerProvider,
                JSONWriter.Feature.WriteNullNumberAsZero);

        Demo demo = new Demo();
        String tmp = JSON.toJSONString(demo, writeContext);
        System.out.println(tmp); //{"a":0,"b":0,"c":1}
    }

    public static class Demo{
        public Long a;
        public Long b;
        public Long c = 1L;
    }
} 

现在Long类型不支持自定义序列化

🚄 FASTJSON2 is a Java JSON library with excellent performance.

My version is as follows: <spring-boot.version>2.7.5</spring-boot.version> <alibaba-cloud.version>2021.0.4.0</alibaba-cloud.version> <springcloud.version>2021.0.4</springcloud.version>

It is found that @ SentinelRestTemplate does not take effect when it is placed in the restTemplate. There is no problem with calls between feigns. I guess the version is incompatible, Can you give me a compatible version? I used the version of spring boot recommended on the official website, which is 2.6.11, and it doesn't work
