我在启动webapp时遇到异常

java.lang.NoSuchMethodError: org.springframework.data.util.ClassTypeInformation.from(Ljava/lang/Class;)Lorg/springframework/data/util/ClassTypeInformation;

这是我的依赖项：

有谁知道这里发生了什么？我试图添加版本，删除它们但它不起作用。我只编写过模型类，但是hibernate并不会因为该异常而创建db。

您正在尝试为您的pom添加更多内容，而且您的版本都存在冲突。别这样做。使用启动器，只使用您真正需要的其他依赖项。

删除大多数依赖项并使用它运行。

<dependencies>
    <!-- Spring -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
    </dependency>
    <!-- hibernate -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-osgi</artifactId>
        <version>5.0.11.Final</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-envers</artifactId>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-ehcache</artifactId>
    </dependency>
    <!-- MySql -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <!-- JUnit -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>pring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <!-- Lombok -->
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
    <!-- Commons -->
    <dependency>
        <groupId>commons-dbcp</groupId>
        <artifactId>commons-dbcp</artifactId>
    </dependency>
</dependencies>

您已经通过初学者获得的所有其他依赖项（spring-context，servlet-api，hibernate-validator）。使用differ4ent版本再次添加它们（比如spring-data的东西）会引入不兼容的版本。

初学者的全部意义在于，您可以获得所需的所有依赖关系以及协同工作的组合。

注意：我将Hibernate版本与Spring Boot 1.4.2管理的版本对齐。
