① java中No value specified是什么意思
no value specified意思是没有指定值。引起原因：当用到了时间等非内置对象时，如果对象为NULL则，会出现此异常。最简单的方法就是保证非内置对象不为NULL。问题解决办法： 读了他的源程序，发现日期java.sql.date主要是用org.apache.commons.beanutils.converters.SqlDateConverter类进行转的：修改下面的代码就可以了 public SqlDateConverter(Object defaultValue) { this.defaultValue = defaultValue; this.useDefault = true; //原本为false; }public SqlDateConverter() { this.defaultValue = null; this.useDefault = true; //原本为false; 修改为true就可以了 }
