解决jar 冲突的一个办法

 

可用类似下面的方式找到类的加载位置

http://stackoverflow.com/questions/227486/find-where-java-class-is-loaded-from

 

package foo;

public class Test
{
    public static void main(String[] args)
    {
        ClassLoader loader = Test.class.getClassLoader();
        System.out.println(loader.getResource("foo/Test.class"));
    }
}

 This printed out:

file:/C:/Users/Jon/Test/foo/Test.class
