arganzheng / Import an existing repository to Bitbucket
Last active December 19, 2015 03:59
Git常用命令备忘录
如果你本地工程已经是一个Git Repository（已经执行过[Import an existing, unversioned code project to an empty repository]），那么可以这样把它加入你在Bitbucket创建的远程仓库中：
cd /path/to/my/repo
# Creates a remote named "origin" pointing at your GitHub/Bitbucket repository (设置远程仓库地址)
git remote add origin ssh://git@bitbucket.org/arganzheng/remote-terminator.git
# Sends your commits in the "master" branches to GitHub/Bitbucket
git push -u origin master
当然在你能push之前必须先设置你的账号信息，并且最好使用Password Caching或者SSH key避免每次提交代码都要提示输入密码。

可以使用这个ok.jsp检查应用是否正常启动
<%@page import="org.springframework.web.context.WebApplicationContext"%>
<%@page import="org.springframework.web.context.support.WebApplicationContextUtils"%>
<%@page import="org.springframework.web.context.support.XmlWebApplicationContext"%>
<%
XmlWebApplicationContext context = (XmlWebApplicationContext)WebApplicationContextUtils.getWebApplicationContext(application);
try{
if(!context.isActive()){
context.refresh();
}

如何打印ibatis拼凑的动态SQL语句

log4j.logger.java.sql.PreparedStatement=debug
log4j.logger.java.sql.Connection=debug

将打印出Connection和Statement信息：

[DEBUG] 11:48:17 Connection - {conn-100000} Connection

[DEBUG] 11:48:17 Connection - {conn-100000} Preparing Statement: select api.id from t_api_metadata_api api, t_api_metadata_module module where api.module_id=module.id and api.source = ? and api.name = ? and api.module_id = ? and module.name = ?

如何autowired sqlMapClient到Dao对象中，解决这个问题`java.lang.IllegalArgumentException: Property 'sqlMapClient' is required`。参考文章: 1. http://edwin.baculsoft.com/2010/08/yet-another-simple-swing-spring-and-ibatis-integration-example/ 2. http://stackoverflow.com/questions/3807707/injecting-derived-property-for-repository-bean-without-autowired-in-super-clas
@Repository
public class ApiDao extends SqlMapClientDaoSupport {
// empty constructor
public ApiDao() {
}
// autowired constructor
// i dont know why, but i cant autowired sqlMapClient directly
// it will cause java.lang.IllegalArgumentException: Property 'sqlMapClient' is required
