第一步：找別人提供的接口，比如在這里我選擇的是聚合數據提供的接口
第二步：要申請相應的appkey方可使用，此參數會作為接口的參數調用。
第三步：調用別人提供的接口方法
代碼如下：

在使用上述代碼時可能會出現異常，一般都是由于jar包不全導致的。
問題一： 拋出 nestableruntimeexception
解決辦法：查看jar包是否完整
包括：commons-beanutils-1.7.0.jar
commons-collections-3.1.jar
commons-lang-2.4.jar （使用過高版本也會報nestableruntimeexception）
commons-logging-1.1.1.jar
ezmorph-1.0.6.jar
json-lib-2.1.jar
log4j.jar
問題二：user-specified log class'org.apache.commons.logging.impl.log4jlogger' cannot be found or is notuseable.
解決辦法：添加log4j的jar包。
總結
以上就是本文關于java編程實現nba賽事接口調用實例代碼的全部內容，希望對大家有所幫助。
