SpringBoot+Mybatis搭建之采坑记录（持续更新...）

Stopping service [Tomcat]  
1.缺少 Serivce注解无法启动tomcat 
2.包名错误
3.写了注解没写参数

使用Eclipse调试Spring boot项目时总是直接进入SilentExitExceptionHandler

解决方案：Window-->Preference-->java-->debug-->Suspend execution on uncaught exceptions选项前面的勾去掉

springBoot 保存中文乱码 插入数据 ？？ 

解决方案：spring.datasource.url=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf8

springBoot上传文件  获取文件 file 为null
MultipartHttpServletRequest mh=(MultipartHttpServletRequest) request;
CommonsMultipartFile cmf=(CommonsMultipartFile) mh.getFile("file"); 

解决方法:
MultipartResolver resolver = new CommonsMultipartResolver(request.getSession().getServletContext());
MultipartHttpServletRequest multipartRequest = resolver.resolveMultipart(request);
CommonsMultipartFile cmf = (CommonsMultipartFile) multipartRequest.getFile("file");

freemarker thymeleaf 访问页面不显示缓存

@RestController 替换为  @Controller

log4j jar包冲突

解决方法：注掉log包添加pom
