Custom output results in the response plugin

ShenYu code:

    public ShenyuPlugin responsePlugin(final ObjectProvider<List<MessageWriter>> httpWriter) {
        Map<String, MessageWriter> writerMap = new LinkedHashMap<>();
        List<MessageWriter> writerList = httpWriter.getIfAvailable(ArrayList::new);
        for (MessageWriter writer : writerList) {
            List<String> supportTypes = writer.supportTypes();
            for (String type : supportTypes) {
                writerMap.put(type, writer);
        return new ResponsePlugin(writerMap);

User-defined implementation: rg.apache.shenyu.plugin.response.strategy.MessageWriter

 * The interface Message writer.
public interface MessageWriter {

     * Write with exchange and shenyu plugin chain.
     * @param exchange exchange the current server exchange
     * @param chain provides a way to delegate to the next filter
     * @return {@code Mono<Void>} to indicate when request processing is complete
    Mono<Void> writeWith(ServerWebExchange exchange, ShenyuPluginChain chain);

     * Support type list.
     * @return the list
    List<String> supportTypes();

Registration Center

The purpose of ShenYu’s registry is to expose the instance of the gateway in order to support ShenYu’s cluster function. You can use the shenyu-nginx project or connect to other load balancing services.


Added support for Nacos

Use: Add the following configuration to the yaml of the gateway bootstarp:

shenyu :
    enabled: true //设置true表示打开
    registerType: nacos //类型为nacos
    serverLists: localhost:8848

Added support for Consul

Use: Add the following configuration to the yaml of the gateway bootstarp:

shenyu :
    enabled: true //设置true表示打开
    registerType: consul //类型为consul
    serverLists: localhost:2379

performance optimization

  • Upgrade SpringBoot to 2.6.8 and Reactor-netty to 1.0.19

  • The gateway customizes Netty full parameter configuration.Meet the user’s personalized configuration

For details, please refer to:

Added matching cache policy.The flow matching efficiency is O(1).

How to use? Configure it in the gateway’s yaml file:

    enabled: true //设置为true 开启
    maxFreeMemory: 256 # //内存大小 单位M

Added custom thread shared thread pool.

How to use? Configure it in the gateway’s yaml file:

   enable: true
   prefix: "shenyu-shared"
   corePoolSize: 200
   maximumPoolSize: 2000
   keepAliveTime: 60000
   maxWorkQueueMemory: 1073741824 # 1GB
   maxFreeMemory: 268435456 # 256MB
