SpringBoot3整合Mybatis-Plus与PageHelper包冲突解决

前言

在将项目由SpringBoot2.x升级为SpringBoot3.2.0时，对Mybatis-Plus及Pagehelper同时进行了升级，升级过程组出现了包冲突以及factoryBeanObjectType异常的情况，下面是一个总结！

1、SpringBoot3在整合Mybatis-Plus与PageHelper的同时会出现，包冲突问题

pagehelper-spring-boot-starter包中会引入mybatis-spring-boot-starter包，会与mybatis-plus-boot-starter出现冲突：

***************************
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:

    com.baomidou.mybatisplus.autoconfigure.MybatisPlusProperties$CoreConfiguration.applyTo(MybatisPlusProperties.java:356)

The following method did not exist:

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

The calling method's class, com.baomidou.mybatisplus.autoconfigure.MybatisPlusProperties$CoreConfiguration, was loaded from the following location:

    jar:file:/D:/m2/com/baomidou/mybatis-plus-spring-boot-autoconfigure/3.5.4.1/mybatis-plus-spring-boot-autoconfigure-3.5.4.1.jar!/com/baomidou/mybatisplus/autoconfigure/MybatisPlusProperties$CoreConfiguration.class

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

    jar:file:/D:/m2/org/mybatis/mybatis/3.5.9/mybatis-3.5.9.jar!/org/apache/ibatis/session/Configuration.class

The called method's class hierarchy was loaded from the following locations:

    org.apache.ibatis.session.Configuration: file:/D:/m2/org/mybatis/mybatis/3.5.9/mybatis-3.5.9.jar


Action:

Correct the classpath of your application so that it contains compatible versions of the classes com.baomidou.mybatisplus.autoconfigure.MybatisPlusProperties$CoreConfiguration and org.apache.ibatis.session.Configuration

解决包冲突：
需要排除mybatis-spring-boot-starter

<dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.4.5</version>
            <exclusions>
                <exclusion>
                    <groupId>org.mybatis.spring.boot</groupId>
                    <artifactId>mybatis-spring-boot-starter</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

2、factoryBeanObjectType错误

出现java.lang.IllegalArgumentException: Invalid value type for attribute 'factoryBeanObjectType': java.lang.String异常信息

java.lang.IllegalArgumentException: Invalid value type for attribute 'factoryBeanObjectType': java.lang.String
	at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.getTypeForFactoryBeanFromAttributes(FactoryBeanRegistrySupport.java:86)

	at com.lhz.demo.DemoApplication.main(DemoApplication.java:10)

解决方案：
需要排除mybatis-plus-boot-starter中mybatis-spring，并且单独引入高版本的mybatis-spring

<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.4.1</version>
            <exclusions>
                <exclusion>
                    <groupId>org.mybatis</groupId>
                    <artifactId>mybatis-spring</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>3.0.3</version>
        </dependency>

3、完整pom配置

<dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.4.5</version>
            <exclusions>
                <exclusion>
                    <groupId>org.mybatis.spring.boot</groupId>
                    <artifactId>mybatis-spring-boot-starter</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.4.1</version>
            <exclusions>
                <exclusion>
                    <groupId>org.mybatis</groupId>
                    <artifactId>mybatis-spring</artifactId>
                </exclusion></exclusions>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>3.0.3</version>
        </dependency>
