如何解决java.net.MalformedURLException? [英] How to resolve java.net.MalformedURLException?
问题描述
我收到此错误:
java.net.MalformedURLException:协议没有找到[java.lang.StringBuilder中]
在下面一行是越来越执行:
URL =新的URL(urlString.toString());
urlString存储以下值:
<$p$p><$c$c>http://maps.google.com/maps?f=d&hl=en&saddr=25.04202,121.534761&daddr=25.05202,121.554761&ie=UTF8&0&om=0&output=kml
是什么原因导致这种异常?
有机会,你更改后没有清洁
URL =新的URL(urlString);
到
URL =新的URL(urlString.toString());
您应该登录传递到URL的构造函数的参数的值。 这是不是你认为它应该是。
urlString将在java.lang.StringBuilder中的形式打印值@ 如果你尝试建立一个url出来,如此抛出异常。
但使用到的字符串将打印在StringBuilder的内置内容字符串的值。
I am getting this error:
java.net.MalformedURLException: Protocol not found[java.lang.StringBuilder]
When the following line is getting executed:
url = new URL(urlString.toString());
urlString stores the following value:
http://maps.google.com/maps?f=d&hl=en&saddr=25.04202,121.534761&daddr=25.05202,121.554761&ie=UTF8&0&om=0&output=kml
What causes this Exception?
Chances are that you didn't clean after changing from
url = new URL( urlString );
to
url = new URL(urlString.toString());
You should log the value of the parameter passed to the constructor of URL. It's not what you think it should be.
urlString would print a value in the form of java.lang.StringBuilder@ thus throwing the exception if you try to build a url out of that.
But using to String will print the value of the content string built by the stringbuilder.
