【问题描述】：

我为春季批次创建了小型 hello world 项目：

build.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 = 1.8
targetCompatibility = 1.8

dependencies {
    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
@EnableBatchProcessing
public 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();

    }

在启动时我看到以下异常：

我不得不说一切都按预期工作，这条痕迹只是在我的日志中乱扔垃圾。但我想避免它。

我找到了解决方法（感谢这个话题How to resolve org.postgresql.jdbc.PgConnection.createClob() is not yet implemented）：

刚刚添加的依赖和excption消失了：

compile('org.hibernate:hibernate-core:5.4.2.Final')

还有更优雅的方式吗？我认为解决方法不是一个好的解决方案

附言

要玩源代码，你可以关注my github repo

【问题讨论】：

  • 不，因为这是Hibernate的问题，所以你需要升级它，hibernate.atlassian.net/browse/HHH-12368
  • 嗯...我用的是最新的spring boot版本
  • 到目前为止，我知道最新的 Spring Boot 版本不包括这个 Hibernate 版本，你可以看看 Spring Boot 版本 2.1.0 包括 Hibernate 版本 5.3 所以我认为 2.1.6 没有t 包括您可以查看添加的依赖项。 spring.io/blog/2018/10/30/spring-boot-2-1-0
  • @Jonathan Johx 你能添加答案吗？这将对未来的谷歌人有所帮助，并将关闭我们的主题
  • 我更新了我的答案，这已在Spring Boot 2.2.0.M(1-4) 上得到修复，所以这个问题应该在这些版本上得到修复。

【解决方案1】：

这是一个休眠issue。 如果您使用 Spring Boot 最新版本从 2.0.x 到 2.1.x 包括Hibernate 5.3.10.final 你可以看看here 但是这个问题在Hibernate version 上得到了修复5.4.0.CR1 然后你需要添加那个依赖或者如果它可能是最新版本：

对于 Gradle：

compile('org.hibernate:hibernate-core:5.4.2.Final')

对于 Maven：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.4.2.Final</version>
</dependency>

更新了“SPRING BOOT 2.2.0.M(1-4)”

此外，Spring boot v2.2.0.Mx 现在包括 Hibernate v5.4.x，然后针对这些版本修复了此问题。
