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

以下回复参考：皆我百晓生、券券喵儿等免费微信小程序作答:

根据您提供的信息，问题可能是由于MyBatis-Plus的版本与Spring Boot的版本不兼容导致的。您可以尝试以下解决方案：

1. 将MyBatis-Plus的版本升级到与Spring Boot版本兼容的版本。例如，如果您使用的是Spring Boot 3.3.2，您可以尝试使用MyBatis-Plus 3.5.5或更高版本。

2. 检查您的项目中是否有其他依赖冲突。您可以使用Maven或Gradle的依赖树功能来查看项目的依赖关系。如果有冲突，请尝试解决它们。

3. 确保您的DriverInfoMapper接口使用了正确的注解。它应该包含@Mapper注解，以便Spring能够识别并自动创建相应的bean。例如：

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface DriverInfoMapper extends BaseMapper<DriverInfo> {
    // Your methods here
}

1. 如果问题仍然存在，您可以尝试在启动类上添加@EnableTransactionManagement注解，以启用事务管理：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@SpringBootApplication
@EnableTransactionManagement
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

希望这些建议能帮助您解决问题。如果问题仍然存在，请随时提供更多详细信息，以便我们能够更好地帮助您。
