iBatis3基于方言(Dialect)的分页

由 人走茶凉 提交于 2020-01-06 17:30:32
(注:以下代码是基于ibatis3 beta4的扩展，ibatis3正式版如果实现改变，将会继续跟进修改) iBatis3默认使用的分页是基于游标的分页，而这种分页在不同的数据库上性能差异不一致，最好的办法当然是使用类似hibernate的基于方言(Dialect)的物理分页功能。 iBatis3现在提供插件功能，通过插件我们可以编写自己的拦截器来拦截iBatis3的主要执行方法来完成相关功能的扩展。 能够拦截的的类如下: Java代码 收藏代码 Executor (update,query,flushStatements,commit,rollback,getTransaction,close,isClosed) ParameterHandler (getParameterObject,setParameters) ResultSetHandler (handleResultSets,handleOutputParameters) StatementHandler (prepare,parameterize,batch,update,query) 但此次我们感兴趣的是Executor.query()方法，查询方法最终都是执行该方法。 该方法完整是: Java代码 收藏代码 Executor.query(MappedStatement ms, Object parameter,

Unsafe类

由 余生颓废 提交于 2020-01-06 14:47:36
一、Unsafe类仅能被BootstrapClassLoader加载的类实例化，用户建的类默认都是ApplicationClassLoader加载的，实例化Unsafe时会报错。可以用反射实例化（方式一）。补充：加启动参数指定当前类由BootstrapClassLoader加载（方式二） private Unsafe() {//构造方法私有化 同单例模式 防止new } @CallerSensitive public static Unsafe getUnsafe() { Class var0 = Reflection.getCallerClass(); if (!VM.isSystemDomainLoader(var0.getClassLoader())) {//判断是否BootstrapClassLoader加载的类执行实例化的 throw new SecurityException("Unsafe"); } else { return theUnsafe; } } 二、反射实现实例化 public class UnsafeTest2 { static final Unsafe unsafe; static final long stateOffset; private volatile long state = 0; static { try { Field field =

What is the maximum value for row and column offsets in VBA for Excel 2010?

由 大兔子大兔子 提交于 2020-01-06 12:40:28
问题 I know a similar question has been answered here: What is the maximum value for row and column Range offset in VBA/Excel? However, that error seemed to be related to the number of rows in the worksheet in Excel 2003. Since I am running Excel 2010 (with 65,536 rows), I don't think my error is related to my worksheet size. Here is the line of code that is giving me Run-time error '6' Overflow: Range("OutputStart").Offset(1 + (iCounter1 - 1) * iDataPoints * 26 + iCounter2 * iDataPoints, 0)

return offset of a string with lua

由 ＊爱你＆永不变心＊ 提交于 2020-01-06 03:11:10
问题 I'm trying to search rather big files for a certain string and return its offset. I'm new to lua and my current approach would look like this: linenumber = 0 for line in io.lines(filepath) do result=string.find(line,"ABC",1) linenumber = linenumber+1 if result ~= nil then offset=linenumber*4096+result io.close end end I realize that this way is rather primitive and certainly slow. How could I do this more efficiently? Thanks in advance. 回答1: If the file is not too big, and you can spare the

EclipseLink generated SQL doesn't include pagination

由 孤街浪徒 提交于 2020-01-06 03:07:49
问题 (My environment: Windows 7 x64 and Server 2008, EclipseLink 2.5.2, I've tried the following with JTDS and the MS JDBC driver, and with MS SQL Server Express 2008 and 2012.) I'm doing a paginated query in a table with anywhere from 5-50 million rows, with about 5 million rows matching the filter criteria. The following is the paginated query I'm using to display this data in the UI 25 rows at a time. The pagination is working properly - the list contains just 25 rows for each page. However,
