maven建立逆向工程中出现的错误

一、连接数据库的driver错误

1、提示：

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. 
The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

原因：

　　com.mysql.jdbc.Driver已经不能用

解决办法：

　　url改成 com.mysql.cj.jdbc.Driver

二、连接数据库的url错误

2、提示：

Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: 
Could not get JDBC Connection; nested exception is 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.

解决办法：

在url代码后面添加?serverTimezone=UTC例如：

jdbc:mysql://localhost:3306/ssm_crud?serverTimezone=UTC

三、缺少依赖导致的错误

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

 原因：

　　缺少slf4j和ibatis的依赖

解决：

<dependency>  
    <groupId>org.slf4jgroupId> 
    <artifactId>slf4j-nopartifactId> 
    <version>1.7.2version> 
dependency>
        
<dependency>
    <groupId>org.apache.ibatisgroupId>
    <artifactId>ibatis-coreartifactId>
     <version>3.0version>
dependency>        

四、逆向工程生成位置路径错误

若运行没有文件生成，相对路径或绝对路径，可以改一下试试
