从错误信息可以看出你引用的两个包中都有Date类，这种情况下你在程序中写全路径就可以了。

[j2nix]

reference to Date is ambiguous, both class
java.util.Date in java.util and class
java.sql.Date in java.sql match
Date currentTime = new Date();

改为：
java.util.Date currentTime = new java.util.Date();

[凋零的老树]

Date在两个类中都有，你必须指明你是引用哪个类的Date

[皮鲁]

指清楚你要用那个包里的Date
