Question

我正在尝试将Spring Boot 1.5.9升级到2.0.3，并且该服务无法启动并出现以下错误：

***************************
APPLICATION FAILED TO START
***************************

Description:

Method mvcConversionService in org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration required a bean named 'entityManagerFactory' that could not be found.


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.


Process finished with exit code 1

该服务在Spring Boot 1.5.9中正常启动。

以下是yaml文件：

    spring:
      application:
      name: customer-crud-application

      datasource:
        url: jdbc:jtds:sqlserver://localhost:1433;databaseName=db-data-dev
        username: sa
        password: pwd
        driverClassName: net.sourceforge.jtds.jdbc.Driver

      jpa:
        show-sql: true
        hibernate:
        dialect: org.hibernate.dialect.SQLServer2012Dialect


    server:
      port: 8080
      max-http-header-size: 65536

和gradle.build

    dependencies {
        compile 'org.springframework.boot:spring-boot-starter-web'
        compile versions.lombok
        compile('net.sourceforge.jtds:jtds')

        compile versions.spring_jdbc
        compile versions.spring_boot_starter_data_jpa
    }

该项目是使用Spring Boot 2.0成功构建的，并且我已经清理了c：/ Users / {user} /。m2文件夹和intelliJ缓存。请帮忙！

Answer 1

I had this issue. When I checked maven build log I have realized that there was an error about hibernate packages about

"invalid LOC header (bad signature)".

I solved by deleting sub directories under

<user-home>\.m2\repository\org\hibernate\hibernate-core and recompiling my project.

@刘晓东..像这样

  spring:
        jpa:    
            show-sql: true
            database: MYSQL
            hibernate:
                ddl-auto: update
                dialect:
                   storage_engine: innodb
        datasource:
            url: jdbc:mysql://localhost:3306/databasename?useSSL=false
            username: user
            password: password

    server:
      port: 9999

Answer 3

添加以下内容。

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

考虑在您的配置中定义一个名为“ entityManagerFactory”的bean。在升级到Spring Boot 2之后，mssqlserver
