我為 spring batch 創建了一個小的 hello world 項目：構建.gradle：buildscript { repositories { mavenCentral() } dependencies { classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.6.RELEASE") }}apply plugin: 'java'apply plugin: 'eclipse'apply plugin: 'idea'apply plugin: 'org.springframework.boot'apply plugin: 'io.spring.dependency-management'bootJar { baseName = 'gs-batch-processing' version = '0.1.0'}repositories { mavenCentral()}sourceCompatibility = 1.8targetCompatibility = 1.8dependencies { compile("org.springframework.boot:spring-boot-starter-batch") compile("org.postgresql:postgresql") compile("org.springframework.boot:spring-boot-starter-data-jpa") //to fix exception on startup //compile('org.hibernate:hibernate-core:5.4.2.Final') testCompile("junit:junit")}配置：@Configuration@EnableBatchProcessingpublic class BatchConfiguration { @Autowired public JobBuilderFactory jobBuilderFactory; @Autowired public StepBuilderFactory stepBuilderFactory; @Autowired private DbPersonWriter dbPersonWriter; @Autowired private ToLowerCasePersonProcessor toLowerCasePersonProcessor; @Value("${app.users-location}") Resource csvResource; @Bean public Job job() { return jobBuilderFactory.get("myJob") .incrementer(new RunIdIncrementer()) .flow(csvToDataBaseStep()) .end() .build(); } private Step csvToDataBaseStep() { return stepBuilderFactory.get("csvToDatabaseStep") .<Person, Person>chunk(100) .reader(csvPersonReader()) .processor(toLowerCasePersonProcessor) .writer(dbPersonWriter) .build(); }

這是一個 Hibernate問題。如果您使用的是 Spring Boot 最新版本，您可以?在2.0.x此處查看，但此問題已在5.4.0.CR1上修復，那么您需要添加該依賴項，或者如果可能，請添加最新版本：2.1.xHibernate 5.3.10.finalHibernate version
對于搖籃：
compile('org.hibernate:hibernate-core:5.4.2.Final')對于胃：
<dependency> ????<groupId>org.hibernate</groupId> ????<artifactId>hibernate-core</artifactId> ????<version>5.4.2.Final</version> </dependency>
更新“彈簧啟動 2.2.0.M(1-4)”
此外Spring boot v2.2.0.Mx，現在還包括Hibernate v5.4.x這些版本的此問題已修復。
