解决：
1.自己继承BeanUtils,并且增加如下代码。
1 static { 2 ConvertUtils.register(new DateConverter(null), java.util.Date.class); 3 ConvertUtils.register(new DateConverter(null), java.sql.Date.class); 4 ConvertUtils.register(new IntegerConverter(null), java.lang.Integer.class); 5 ConvertUtils.register(new LongConverter(null), java.lang.Long.class); 6 }
