SpringBoot整合Mybatis-plus8.0.30报错

Question

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'persistenceExceptionTranslationPostProcessor' defined in class path resource [org/springframework/boot/autoconfigure/dao/PersistenceExceptionTranslationAutoConfiguration.class]: Unsatisfied dependency expressed through method 'persistenceExceptionTranslationPostProcessor' parameter 0: Invalid bean definition with name 'driverInfoMapper' defined in file [E:\workspace\Springsecture-01-test\target\classes\com\xgj\application\mapper\DriverInfoMapper.class]: Invalid value type for attribute 'factoryBeanObjectType': java.lang.String

使用的是mybatis-plus-boot-starter下3.5.3.2的版本；spring-boot-starter-parent使用的是3.3.2版本报的错；启动类上加了 代码

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
@MapperScan("com.xgj.application.mapper")

后面改成下面依赖

  <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-spring-boot3-starter</artifactId>
            <version>3.5.5</version>
        </dependency>

继续报错，还是报如下错(依赖树没有冲突)

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'driverInfoServiceImpl': Unsatisfied dependency expressed through field 'baseMapper': Error creating bean with name 'driverInfoMapper' defined in file [E:\workspace\Springsecture-01-test\target\classes\com\xgj\application\mapper\DriverInfoMapper.class]: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

问题分析

根据报错信息，问题主要集中在 driverInfoMapper 这个 Bean 的定义上。具体错误是 Invalid value type for attribute 'factoryBeanObjectType': java.lang.String，以及 Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required。

解决方案

1. 检查 DriverInfoMapper 接口

首先，确保 DriverInfoMapper 接口正确继承了 MyBatis-Plus 的 BaseMapper 接口，并且没有其他错误的注解或配置。

package com.xgj.application.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.xgj.application.entity.DriverInfo;

public interface DriverInfoMapper extends BaseMapper<DriverInfo> {
    // 其他自定义方法
}

2. 检查 application.properties 或 application.yml 配置文件

确保数据库连接配置正确，特别是 mybatis-plus 相关的配置。

# application.properties
spring.datasource.url=jdbc:mysql://localhost:3306/your_database
spring.datasource.username=root
spring.datasource.password=your_password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

mybatis-plus.mapper-locations=classpath:mapper/*.xml
mybatis-plus.type-aliases-package=com.xgj.application.entity

3. 检查依赖

确保依赖没有冲突，并且使用正确的版本。根据报错信息，建议使用以下依赖：

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.5.3.2</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jdbc</artifactId>
</dependency>
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.26</version>
</dependency>

4. 检查启动类注解

确保启动类上的注解配置正确，特别是 @MapperScan 注解。

package com.xgj.application;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
@MapperScan("com.xgj.application.mapper")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

5. 检查 DriverInfoServiceImpl 类

确保 DriverInfoServiceImpl 类正确注入了 DriverInfoMapper。

package com.xgj.application.service.impl;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.xgj.application.entity.DriverInfo;
import com.xgj.application.mapper.DriverInfoMapper;
import com.xgj.application.service.DriverInfoService;
import org.springframework.stereotype.Service;

@Service
public class DriverInfoServiceImpl extends ServiceImpl<DriverInfoMapper, DriverInfo> implements DriverInfoService {
    // 其他业务逻辑
}

总结

通过以上步骤，逐一检查和修正 DriverInfoMapper 的定义、配置文件、依赖、启动类注解以及 DriverInfoServiceImpl 类的注入，应该能够解决 UnsatisfiedDependencyException 和 BeanDefinitionStoreException 的问题。如果问题依然存在，建议检查日志中的其他错误信息，或者尝试重新构建项目。
