报错问题解决(执行入口程序后):
- 1、Error starting ApplicationContext. To display the conditions report re-run your application with ‘debug‘ enabled.
2019-06-20 22:37:15.167 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘demo‘: Unsatisfied dependency expressed through field ‘template‘; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘sqlSessionTemplate‘ defined in class path resource- 解决:一般是数据库配置有问题,比如application.yml文件中,数据库的url: jdbc:mysql://localhost:3306/course,若该数据库只有localhost有链接权限,其他ip都无权限,则报此错误,如将localhost改成127.0.0.1,就会出现这种错误。
- 2、ERROR com.zaxxer.hikari.pool.HikariPool - HikariPool-1 - Exception during pool initialization.
java.sql.SQLException: The server time zone value ‘?й???????‘ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.- 解决:造成这个原因是因为mysql的版本过高。修改为:
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.24</version> <scope>runtime</scope> </dependency>
SpringBoot 去除"No MyBatis mapper was found in ‘[com.XXX]‘ package. " 警告
仔细观察发现,这个包恰恰是 Application 主类的包,看样子是默认扫描了。虽然不影响使用,但不想让这个警告出现,怎么去掉这个警告呢?偶然想到一个思路,既然你要找主类包里的mapper,我就给你一个mapper。如下
NoWarnMapper.java package com.course; @org.apache.ibatis.annotations.Mapper public interface NoWarnMapper { }
请求的响应中,出现EDT错误
解决如下:(若没有出现EDT错误,则不需要加如下内容)
在application.yml中,加入serverTimezone=GMT
