maven配置正确，其它项目可以正常启动，就这个项目一直启动不了，试了war和war exploded模式都不行。
日志如下：
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

望采纳，谢谢
我觉得有可能是中文路径乱码，或者是bean注入失败，检查一下那个方法没有注入
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in file
报错信息 bean注入失败 加载sqlSession时报错，看配置文件 如果不想连接就在启动类上加注解
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})根据 log \WEB-INF\classes\spring\spring-context.xml]: Invocation of init method failed; nested exception is com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
配置文件里的mysql链接失败,看看是不是地址或者账号密码错了
在做登录吗？看下mapper编译有没有class和xml在同一个目录
