1、报错：[org/springframework/security/config/annotation/authentication/configurers/GlobalAuthenticationConfigurerAdapter.class] cannot be opened because it does not exist

参考这里。
启动时排除SecurityAutoConfiguration类。

@SpringBootApplication(exclude = {
							DataSourceAutoConfiguration.class,
							org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class,
							org.activiti.spring.boot.SecurityAutoConfiguration.class })
public class RuoYiApplication
{
	...
}

2、报错：The following method did not exist: org.apache.ibatis.session.Configuration.setDefaultEnumTypeHandler(Ljava/lang/Class;)V

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.mybatis.spring.SqlSessionFactoryBean.buildSqlSessionFactory(SqlSessionFactoryBean.java:563)

The following method did not exist:

    org.apache.ibatis.session.Configuration.setDefaultEnumTypeHandler(Ljava/lang/Class;)V

The method's class, org.apache.ibatis.session.Configuration, is available from the following locations:

    jar:file:/D:/sde/maven/repository/org/mybatis/mybatis/3.4.2/mybatis-3.4.2.jar!/org/apache/ibatis/session/Configuration.class

It was loaded from the following location:

    file:/D:/sde/maven/repository/org/mybatis/mybatis/3.4.2/mybatis-3.4.2.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.apache.ibatis.session.Configuration

将mybatis从3.4.2更换成3.5.5。在POM.xml中添加：

        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.5.5</version>
        </dependency>
