问题：

springboot版本问题 Cannot load configuration class: org.mybatis.spring.boot.autoconfigure.MybatisAutoConfiguration

http://3ms.huawei.com/km/blogs/details/5457353

当你看到这个异常时,你试一试把springboot版本升级

Cannot load configuration class: org.mybatis.spring.boot.autoconfigure.MybatisAutoConfiguration

	
		
			
				
				org.springframework.boot
				spring-boot-dependencies
				1.4.2.RELEASE
				pom
				 import
			
		
	

 

使用mybatis报错The error occurred while setting parameters的终极解决办法

1.检查sql语句，最好的检查方法就是将sql语句复制到查询器中执行一遍。

2.检查Mapper接口，参数名一定要对上！！！

3.检查字段是否出现sql关键字！（比如call），这个很重要，因为call在java中并不是关键字，但是在sql中是关键字！

 

 service 打成可执行性的jar包
