struts2自定义类型转换器

1.1.  struts2自定义类型转换器

1)        自定类型转换类，继承DefaultTypeConverter类

package com.morris.ticket.conversion;   import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Map;   import com.opensymphony.xwork2.conversion.impl.DefaultTypeConverter;   public class DateConversion extends DefaultTypeConverter {            public Object convertValue(Map<String, Object> context, Object value,                             Class toType) {                      String[] parameters = (String[]) value;                    // 从页面中name获得的参数有多个，取第一个                    String dateStr = parameters[0];                      SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");                      // 如果要转换的类型是时间类型                    if (toType == Date.class) {                             try {                                      return sdf.parse(dateStr);                             } catch (ParseException e) {                                      e.printStackTrace();                             }                    }                    return null;          }   }

2)        配置自定义类型转换器，在src目录下新建xwork-conversion.properties文件

java.util.Date:com.morris.ticket.conversion.DateConversion
