springmvc整合mybaits配置数据源问题

程序员文章站 2022-03-30 19:53:39

...

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
