问题概述

这个问题是一个老项目中遇见的，

关键依赖环境：

JDK 1.8

Spring boot 2.2.6.RELEASE

Mybatis-plus 3.4.1

项目打包编译通过，但是不管怎么样也无法启动，

报错：“ ...beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'xxx' ”

如下图：

具体异常信息如下：


org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'dbConfig': Unsatisfied dependency expressed through field 'mySQLQueryDao'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mySQLQueryDao' defined in file [E:\MY_CODE\...\project-name\target\classes\io\catalog\dao\MySQLQueryDao.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.baomidou.mybatisplus.autoconfigure.MybatisPlusAutoConfiguration': Unexpected exception during bean creation; nested exception is java.lang.TypeNotPresentException: Type org.apache.ibatis.mapping.DatabaseIdProvider not present

解决办法

关于这个问题的解决，从错误提示信息来看，依赖找不到，运行时的错误，实例无法被实例化，

先一步步来分析，

1、检查Mapper.xml 引用路径配置正确

实体对象的Mapper.xml中的两个路径必须配置正确，

一个是mapper.namespace，

一个是resultMap.type，

如下图：

2、检查Mapper.xml映射路径正确

mybatis-plus:
  mapperLocations: classpath:mapper/**/*.xml

如下图：

3、检查项目Application的@MapperScan

org.apache.ibatis.annotations.Mapper
用@Mapper注解的Mapper持久化Dao类所在目录，

启动时，会扫描注册到Spring容器中，

4、检查项目的Maven build

如果是Maven项目，检查调用的 Mapper 接口，如果在目标文件中没有找到 Mapper 映射的配置文件，在项目的 target 目标文件中可以看到，与接口对应的 Mapper 文件未加载，所以在程序启动时，就无法加载对应的映射文件，

在pom.xml的build节点中加入如配置（build节点的全部信息）：

	<build>
		<resources>
			<resource>
				<directory>src/main/java</directory>
				<includes>
					<include>**/*.properties</include>
					<include>**/*.xml</include>
				</includes>
				<filtering>false</filtering>
			</resource>
			<resource>
				<directory>src/main/resources</directory>
				<includes>
					<include>**/*.properties</include>
					<include>**/*.xml</include>
				</includes>
				<filtering>false</filtering>
			</resource>
		</resources>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
			<plugin><!--编译跳过测试文件检查的生命周期-->
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-surefire-plugin</artifactId>
				<configuration>
					<skip>true</skip>
				</configuration>
			</plugin>
		</plugins>
	</build>

如下图：

Maven build参考，

5、mybatis-plus-boot-starter版本冲突（博主是本问题导致的）

关于这个问题，

mybatis-plus-boot-starter
spring-boot-starter-parent
即Mybatis和Spring boot的版本冲突导致的，
把mybatis-plus-boot-starter修改正确即可！

参考mvnrepository.com修改正确即可，

之前为了解决
import org.apache.ibatis.annotations.Mapper;
@Mapper
导包的问题，
引入了tk.mybatis组件包：

        <dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper-spring-boot-starter</artifactId>
            <version>2.1.5</version>
        </dependency>

这个包和com.baomidou组件包：

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.3</version>
            <exclusions>
                <exclusion>
                    <groupId>com.baomidou</groupId>
                    <artifactId>mybatis-plus-generator</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

冲突了！！！
去除其中一个即可，
这里一般去除tk.mybatis组件包，用com.baomidou组件包即可！

6、启动测试

终于成功的启动了！！！

好了，关于 ...beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'xxx' 的解决办法就写到这儿了，如果还有什么疑问或遇到什么问题欢迎扫码提问，也可以给我留言哦，我会一一详细的解答的。
