SpringBoot3.2.0整合MyBatis-plus的相关问题

Springboot3.2.0 GA版发布于 2023-11-24

环境：SpringBoot3.2.0+Gradle8.x+Java17

1. build.gradle

plugins {id 'java'id 'org.springframework.boot' version '3.2.0'
}group = 'com.yuan'
version = '1.0.0'
java {sourceCompatibility = '17'
}configurations {compileOnly {extendsFrom annotationProcessor}
}repositories {mavenLocal()mavenCentral()
}dependencies {//....implementation 'org.springframework.boot:spring-boot-starter-actuator'implementation 'com.baomidou:mybatis-plus-boot-starter:3.5.4.1'
}tasks.named('test') {outputs.dir snippetsDiruseJUnitPlatform()
}tasks.named('asciidoctor') {inputs.dir snippetsDirdependsOn test
}hibernate {enhancement {enableAssociationManagement = true}
}

2. mybatis-plus整合问题

1. 错误描述

升级后出现java.lang.IllegalArgumentException: Invalid value type for attribute 'factoryBeanObjectType': java.lang.String 问题，如下

2. 问题分析及解决

1. 原因分析

经排查发现引入的mybaits-plus版本为3.5.4.1,依赖spring与mybatis整合的版本为org.mybatis:mybatis-spring:2.1.1,

所以会导致Invalid value type for attribute 'factoryBeanObjectType': java.lang.String的问题

2. 解决方式

有两种解决方式

1. 升级Mybatisplus的版本到最高版本,如implementation 'com.baomidou:mybatis-plus-generator:3.5.5'
2. 还是用3.5.4.1版本，需要在build.gradle中引入mybatis-spring的高版本，如下mybatis-spring:3.0.3

plugins {id 'java'id 'org.springframework.boot' version '3.2.0'
}group = 'com.yuan'
version = '1.0.0'
java {sourceCompatibility = '17'
}configurations {compileOnly {extendsFrom annotationProcessor}
}repositories {mavenLocal()mavenCentral()
}dependencies {//....implementation 'org.springframework.boot:spring-boot-starter-actuator'implementation 'com.baomidou:mybatis-plus-boot-starter:3.5.4.1'// https://mvnrepository.com/artifact/org.mybatis/mybatis-spring//解决MyBaits-Plus依赖中spring-mybatis:2.1.1版本报`Invalid value type for attribute 'factoryBeanObjectType': java.lang.String`的问题implementation 'org.mybatis:mybatis-spring:3.0.3'}tasks.named('test') {outputs.dir snippetsDiruseJUnitPlatform()
}tasks.named('asciidoctor') {inputs.dir snippetsDirdependsOn test
}hibernate {enhancement {enableAssociationManagement = true}
}
