坑爹的No matching method
来源:互联网 发布:mysql sp help 编辑:程序博客网 时间:2024/06/03 16:53
最近自己写了个udf,发现怎么样都不行 ,代码如下:
public String evalulate()
{
return "hello worlds!";
}
public String evalulate(String str)
{
return "hello world!"+str;
}
提示错误都是:
FAILED: Error in semantic analysis: Line 1:7 Wrong arguments ''1'': No matching method for class
这个问题坑了我两天,昨天才发现,竟然方法名字写错了。其实错误的提示也已经很明显了。方法名字不对。
evalulate-->evaluate
改成这样就对了。。
