一、报错信息：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
    2020-06-17 19:59:42.456 ERROR 9977 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 
    
    ***************************
    APPLICATION FAILED TO START
    ***************************
    
    Description:
    
    An attempt was made to call a method that does not exist. The attempt was made from the following location:
    
        org.hibernate.jpa.boot.internal.PersistenceUnitInfoDescriptor.getValidationMode(PersistenceUnitInfoDescriptor.java:88)
    
    The following method did not exist:
    
        javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;
    
    The method's class, javax.persistence.spi.PersistenceUnitInfo, is available from the following locations:
    
        jar:file:/Users/wangjun/.m2/repository/javax/persistence/persistence-api/1.0/persistence-api-1.0.jar!/javax/persistence/spi/PersistenceUnitInfo.class
        jar:file:/Users/wangjun/.m2/repository/jakarta/persistence/jakarta.persistence-api/2.2.3/jakarta.persistence-api-2.2.3.jar!/javax/persistence/spi/PersistenceUnitInfo.class
    
    It was loaded from the following location:
    
        file:/Users/wangjun/.m2/repository/javax/persistence/persistence-api/1.0/persistence-api-1.0.jar
    
    
    Action:
    
    Correct the classpath of your application so that it contains a single, compatible version of javax.persistence.spi.PersistenceUnitInfo
    
    Disconnected from the target VM, address: '127.0.0.1:64263', transport: 'socket'
    
    Process finished with exit code 1

二、原因分析：

项目是SpringBoot+mybatis，在pom.xml文件中引入了tk.mybatis的依赖，因为tk.mybatis会自动引用依赖引入persistence-api-1.0.jar包，而persistence-api-1.0.jar的PersistenceUnitInfo类中并没有getValidationMode()方法，而在springboot（2.1.0.RELEASE）中自动引入的依赖persistence-api-2.2.jar包的PersistenceUnitInfo类则有实现getValidationMode()方法。此时两个类冲突了，导致报了以下的错误。解决方法就是在tk.mybatis中排除掉persistence-api-1.0.jar的自动依赖

三、解决方法

错误的引入方法：

<dependency>
                <groupId>tk.mybatis</groupId>
                <artifactId>mapper</artifactId>
                <version>4.1.5</version>
            </dependency>

正确的引入方法：

<dependency>
                <groupId>tk.mybatis</groupId>
                <artifactId>mapper</artifactId>
                <version>4.1.5</version>
                <exclusions>
                    <exclusion>
                        <groupId>javax.persistence</groupId>
                        <artifactId>persistence-api</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
