dt.Columns.Add("ColumnName", typeof(Boolean)); dt.Columns["ColumnName"].DefaultValue = false; 发现这样各种尝试设置...DefaultValue 值都没有用,调试代码看dt里新增ColumnName列中还是没值。...new DataColumn(); cid_column.DataType=typeof(String); cid_column.ColumnName = "cid"; cid_column.DefaultValue
@RequestParam使用defaultValue属性设置默认值 注意设置必须是string类型的,框架自己会做转换 @RequestParam(value = "page", required...= false, defaultValue = "1") Integer page, @RequestParam(value = "size", required = false) Integer
问题,为了方便调试,引入了swagger2,但是在第一次访问的时候总是报 Illegal DefaultValue null for parameter type integer 让人看着很不输入
在Spring Boot中集成Swagger2,使用@ApiImplicitParam注解时出现如下异常“Illegal DefaultValue 0 for parameter type integer...”,异常详情如下: Illegal DefaultValue 0 for parameter type integer java.lang.NumberFormatException: For input...= "id", value = "用户ID", paramType = "path", required = true, dataType = "Long", defaultValue...而且异常的描述具有迷糊性,说什么“DefaultValue”类型非法。...= "id", value = "用户ID", paramType = "path", required = true, dataType = "Long", defaultValue
