这几天搭建了个自己测试用的框架，springmvc+mybatis，由于使用maven，所以就想尝尝鲜，各种jar包都去搞得最新的，结果悲剧就此上演，首先配置数据库就让差点没吐出血来。记录下来

jdbc.properties:
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull jdbc.username=root jdbc.password=root
数据源方案配置一 ，写死连接在xml中是没有问题的。
数据源方案配置二，启动报错如下：
Caused by: java.sql.SQLException: org.logicalcobwebs.proxool.ProxoolException: Couldn't load class ${jdbc.driver}
将default-autowire="byName"去掉，报错如下：
Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required
奶奶的，不是说sqlSessionFactory是自动注入的么，居然报错。
原来是
mybaits-spring-1.2.2.jar的SqlSessionDaoSupport
/**
* Convenient super class for MyBatis SqlSession data access objects.
* It gives you access to the template which can then be used to execute SQL methods.
* <p>
* This class needs a SqlSessionTemplate or a SqlSessionFactory.
* If both are set the SqlSessionFactory will be ignored.
* <p>
* {code Autowired} was removed from setSqlSessionTemplate and setSqlSessionFactory
* in version 1.2.0.
*
* @author Putthibong Boonbong
*
* @see #setSqlSessionFactory
* @see #setSqlSessionTemplate
* @see SqlSessionTemplate
* @version $Id$
*/
public abstract class SqlSessionDaoSupport extends DaoSupport {
* This class needs a SqlSessionTemplate or a SqlSessionFactory
晕死，于是在继承SqlSessionDaoSupport的类中注入sqlSessionFactory
如下：
@Service(value="userService")
public class UserServiceImpl extends SqlSessionDaoSupport implements UserService{
/**
* sqlSessionFactory setSqlSessionFactory
*/
@Autowired
@Override
public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {
super.setSqlSessionFactory(sqlSessionFactory);
}
}
启动就正常了，根据：http://www.oschina.net/code/snippet_1029551_21550
将这个问题记录下，目前还不知道怎么用xml实现
