Failed to bind properties under 'mybatis.configuration.mapped-statements[0]

原因是mybatis版本不兼容导致

在springcloud项目版本设置

当springboot为2.1.5.RELEASE

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.5.RELEASE</version>
        <relativePath/>
    </parent>

    <!--这里是为了统一控制版本-->
    <dependencyManagement>
        <dependencies>
            <!--引入springcloud版本-->
            <dependency>
                <groupId>org.springframework.cloud</groupId>

                <type>pom</type>
                <scope>import</scope>
            </dependency>



        </dependencies>

            <version>2.0.1</version>
        </dependency>

　　springboot为2.2.5.RELEASE版本时

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.5.RELEASE</version>

            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.2.1</version>
        </dependency>

　　当springboot版本为2.3.2.RELEASE

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.2.RELEASE</version>
