Spring 3 and MyBatis 3.0.4 / 3.0.6: MalformedParameterizedTypeException
- 博客分类:
- java
根据网络的资料通过maven构建了一个Spring+MyBatis项目,其中pom.xml文件中引入mybatis和Spring架包:
<!-- spring webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>3.0.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>3.0.6.RELEASE</version> </dependency> <!-- spring-mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.0.2</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.0.4</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.14</version> </dependency>
结果运行后报错如下:

困恼啊 一遍一遍查看代码 都无发现重大错误 后在国外的老外的一片文章中找到了和我出现一样问题
看后顿然醒悟,原来自己”二二“地搞错了版本,解决方案,把mybatis的版本从3.0.4改成更高一点版本3.0.6便可:
<dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.0.6</version> </dependency>
总结:问题不是很严重,只怪自己太小白,因为问题太简单了,别人都没出现这种”二“不能在“二”的低级错误,故写这篇文章来取消自己一下!
