我们将创建一个方法initializeMap来向 Map 中添加一些元素,如下所示: publicstaticvoidinitializeMap(){exampleMap.put("Apple",1);// 将键值对 "Apple" -> 1 添加到 Map 中exampleMap.put("Banana",2);// 将键值对 "Banana" -> 2 添加到 Map 中exampleMap.put("Orange",3);// 将键值对 "Orange"...

由于该类的initialize方法注解有@PostConstruct,因此会在初始化后执行.代码如下: @PostConstruct public void initialize() { // 1. 尝试获取主数据源 返回null,意味着主数据源不存在 DataSource primaryDataSource = getPrimaryDataSource(); // 2. 实例化DataSourcePoolMetadataProvider ...
private void initializePool() { for (int i = 0; i < maxConnections; i++) { try { ZooKeeper zk = new ZooKeeper(connectionString, 3000, watchedEvent -> {}); pool.add(zk); } catch (IOException e) { e.printStackTrace(); }
