resteasy - Rest Client - 我可以设置 connectionPoolSize 吗？

Question

Microprofile 允许从 RestClient 定义 connectionPoolSize，如下所示：

io.smallrye.restclient.tests.proxy.HelloClient/property/resteasy.connectionPoolSize = 4

当我在我的项目中设置这个属性时，quarkus 会忽略它。我该如何定义它？

Answer 1

如果您配置的客户端是 @RegisterRestClient(configKey="myClient")，则要设置池大小，请使用：

quarkus.rest-client.myClient.connection-pool-size: 5

（...而不是 myClient/mp-rest/connectionPoolSize）

Answer 2

1. 创建类MyRestClientBuilderListener实现RestClientBuilderListener：

package org.myproject.config

public class MyRestClientBuilderListener implements RestClientBuilderListener {
    
    static final Logger LOG = LoggerFactory.getLogger(MgiRestClientBuilderListener.class);
    static final String CONNECTION_POOL_SIZE_PROP = "config.restclient.connectionPoolSize";

    @Override
    public void onNewBuilder(RestClientBuilder builder) {
        Config cfg = ConfigProvider.getConfig();
        Integer poolSizeConnection = cfg.getValue(CONNECTION_POOL_SIZE_PROP, Integer.class);
        
        if(poolSizeConnection == null) {
            poolSizeConnection = 50;//default
        }

        builder.property("resteasy.connectionPoolSize", poolSizeConnection);
    }
}

2. 在META-INF\services中创建名为org.eclipse.microprofile.rest.client.spi.RestClientBuilderListener的文件，其内容为：

org.myproject.config.MyRestClientBuilderListener
