The following method did not exist:

    'void org.apache.ibatis.session.Configuration.parsePendingMethods(boolean)'

The calling method's class, com.baomidou.mybatisplus.core.MybatisMapperAnnotationBuilder, was loaded from the following location:

    jar:file:/C:/MyApplication/Work/repository/maven/repository/com/baomidou/mybatis-plus-core/3.5.7/mybatis-plus-core-3.5.7.jar!/com/baomidou/mybatisplus/core/MybatisMapperAnnotationBuilder.class

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

    jar:file:/C:/MyApplication/Work/repository/maven/repository/org/mybatis/mybatis/3.5.14/mybatis-3.5.14.jar!/org/apache/ibatis/session/Configuration.class

    org.apache.ibatis.session.Configuration: file:/C:/MyApplication/Work/repository/maven/repository/org/mybatis/mybatis/3.5.14/mybatis-3.5.14.jar

Action:

Correct the classpath of your application so that it contains compatible versions of the classes com.baomidou.mybatisplus.core.MybatisMapperAnnotationBuilder and org.apache.ibatis.session.Configuration

原因

1	MyBatis 和 MyBatis-Plus 的版本冲突

引入 spring-cloud-gateway 时，提示了 Spring MVC 与 Spring Cloud Gateway 不兼容

原因

Spring Cloud Gateway 是基于 响应式（Reactive） 编程模型，而 Spring MVC 是基于阻塞式的模型。

解决方案

修改配置文件，设置为响应式 Web 应用程序

application.yml

spring:
main:
web-application-type: reactive

移除 spring-boot-starter-web 依赖

因为其是为 Spring MVC 服务的，如果需要使用 Spring Cloud Gateway 和响应式编程，应使用 spring-boot-starter-webflux 代替。

移除 spring-boot-starter-web：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

添加 spring-boot-starter-webflux：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
