这个是排序工具类ListSortUtil.java（是安装字段属性值进行排序，比如表中有userid，username,userpwd）,可以按照表中任何一个属性值进行排序，排序规则如下：

import java.util.List;
import java.lang.reflect.Method;
public class ListSortUtil<T>
/**
* @param targetList 目标排序List

* @param sortMode 排序方式（asc or desc）
*/

public void sort(List<T> targetList, final String sortField, final String sortMode)

public int compare(Object obj1, Object obj2)
int retVal = 0;
try
//首字母转大写
String newStr=sortField.substring(0, 1).toUpperCase()+sortField.replaceFirst("\\\\w","");
String methodStr="get"+newStr;
Method method1 = ((T)obj1).getClass().getMethod(methodStr, null);
Method method2 = ((T)obj2).getClass().getMethod(methodStr, null);
if (sortMode != null && "desc".equals(sortMode))
retVal = method2.invoke(((T) obj2), null).toString().compareTo(method1.invoke(((T) obj1), null).toString()); // 倒序
else
retVal = method1.invoke(((T) obj1), null).toString().compareTo(method2.invoke(((T) obj2), null).toString()); // 正序
catch (Exception e)
throw new RuntimeException();
