Java编程实现NBA赛事接口调用实例代码

2021-02-07 17:01笑容刺眼 Java教程

这篇文章主要介绍了Java编程实现NBA赛事接口调用实例代码,具有一定参考价值,需要的朋友可以了解下。

第一步:找别人提供的接口,比如在这里我选择的是聚合数据提供的接口

第二步:要申请相应的appkey方可使用,此参数会作为接口的参数调用

第三步:调用别人提供的接口方法

代码如下:

在使用上述代码时可能会出现异常,一般都是由于jar包不全导致的。

问题一: 抛出 nestableruntimeexception

Java编程实现NBA赛事接口调用实例代码

解决办法: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 (使用过高版本也会报nestableruntimeexception)

commons-logging-1.1.1.jar

ezmorph-1.0.6.jar

json-lib-2.1.jar

log4j.jar

问题二:user-specified log class'org.apache.commons.logging.impl.log4jlogger' cannot be found or is notuseable.

解决办法:添加log4j的jar包。
