pulsar-client-1-2 PulsarClient构造函数

前言

上文说到，PulsarClient通过链式调用构建，而在build()中调用了new PulsarClientImpl(conf)，而Producer 本文通过解析构造函数，了解其主要结构。

// 创建PulsarClient
PulsarClient client = PulsarClient.builder()
        .serviceUrl("pulsar://localhost:6650")
        .build();

@Override
public PulsarClient build() throws PulsarClientException {
   
    
    
    // 1. 参数检验
    ...

	// 2. 构造PulsarClient
    PulsarClient client = new PulsarClientImpl(conf);
    if (conf.getServiceUrlProvider() != null) {
   
    
    
        conf.getServiceUrlProvider().initialize(client);
    }
    return client;
}

PulsarClient构造函数

构造函数依次调用了下文的ctor1、ctor2、ctor3(见注释)。其中ctor1创建了EventLoopGroup, ctor2创建了ConnectionPool，ctor3创建的组件较多，内容省略。

// ctor1
public PulsarClientImpl(ClientConfigurationData conf) throws PulsarClientException {
   
    
    
    this(
