Question

您好我正在尝试使用spring数据jpa在wildfly 9上创建一个spring mvc应用程序，当我添加jpa相关的配置和依赖项时，它会收到NoClassDef Found错误。这是服务器日志：

引起：java.lang.NoClassDefFoundError：org / hibernate / HibernateException 在org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter。（HibernateJpaVendorAdapter.java:60）

Maven pom：

配置类

package com;

//import skipped...

@Configuration
@ComponentScan(basePackages = "com*")
@EnableWebMvc
@EnableJpaRepositories
@EnableTransactionManagement
public class TestAppConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.freeMarker().cache(false);
    }

    @Bean
    public FreeMarkerConfigurer freeMarkerConfigurer() throws TemplateException, IOException {
        FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
        configurer.setTemplateLoaderPath("/WEB-INF/freemarker/");
        return configurer;
    }

    @Bean
    public AbstractPlatformTransactionManager transactionManager() {
        return new JpaTransactionManager(entityManagerFactory());
    }

    @Bean
    public EntityManagerFactory entityManagerFactory() {
        final LocalContainerEntityManagerFactoryBean bean = new LocalContainerEntityManagerFactoryBean();
        bean.setJpaVendorAdapter(new HibernateJpaVendorAdapter()); //This is the line the log complaining
        bean.setDataSource(dataSource());
        final Properties props = new Properties();
        props.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
        props.setProperty("hibernate.hbm2ddl.auto", "validate");
        props.setProperty("hibernate.show_sql", "true");
        props.setProperty("hibernate.format_sql", "true");

        bean.setJpaProperties(props);
        return bean.getObject();
    }

    @Bean
    public DataSource dataSource() {
        final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
        dsLookup.setResourceRef(true);
        DataSource dataSource = dsLookup.getDataSource("java:/PostgresDS");
        return dataSource;
    }
}

我做错了吗？

对于maven，我在某处读到使用jpa不应该包含hibernate-core但是HibernateException在那里，但是include和exclude它会产生同样的错误。

Project使用eclipse和wildfly插件在wildfly 9上运行。

非常感谢你。

你需要为jpa 2.1 api提供提供的范围，并从hibernate核心中排除相同的api才能工作。

Wildfly，spring data jpa get NoClassDefFoundError：HibernateException
