Question

我的应用程序正在使用Spring Boot +批处理+ gradle + mssql + aws Lambda。我将罐子上传到s3存储桶中，并测试了lambda功能 “ errorMessage”：“没有可用的名为'entityManagerFactory'的bean”， “ errorType”：“ org.springframework.beans.factory.NoSuchBeanDefinitionException”。应用程序在本地运行良好，尚未设置AWS Cloud RDBMS，我想知道这是错误的原因是因为云中不存在DATABASE和TABLES。有任何建议专家吗？

我通过升级Javassist版本解决了相同的问题。更新Javassist时，我从工件“ spring-boot-starter-data-jpa”中排除了旧版本的Javassist。

对于Gradle Project更新build.gradle，如下所示：

compile('org.springframework.boot:spring-boot-starter-data-jpa:2.0.4.RELEASE'){
        exclude group: 'org.javassist', module: 'javassist'
    }
compile 'org.javassist:javassist:3.22.0-GA'

对于Maven项目，更新pom.xml，如下所示：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
    <exclusions>
        <exclusion>
            <artifactId>javassist</artifactId>
            <groupId>org.javassist</groupId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.22.0-GA</version>
    <scope>runtime</scope>
</dependency>
