java - 带有 JTA 事务的 Spring java 配置

Question

我在 Spring 中编写了一个简单的项目，我想使用 JTA 事务。我想要 java 类基本配置，而不是 xml。我在互联网上搜索好的配置，但没有找到任何有趣的教程。我的配置类:

    package pl.airlines.configuration;

import java.util.Properties;
import javax.persistence.EntityManagerFactory;
import javax.sql.DataSource;
import org.springframework.core.env.Environment;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver;
import org.springframework.jdbc.datasource.lookup.JndiDataSourceLookup;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.jta.JtaTransactionManager;

@Configuration
@ComponentScan("pl.airlines")
@EnableTransactionManagement
public class PersistenceConfig {

    @Bean
    public PlatformTransactionManager platformTransactionManager() {
        return new JtaTransactionManager();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(true);
        vendorAdapter.setShowSql(true);
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setDataSource(dataSource());
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan("pl.airlines.model");

        factory.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
        return factory;
    }

    @Bean
    public DataSource dataSource() {
        JndiDataSourceLookup jndiDataSourceLookup = new JndiDataSourceLookup();
        return jndiDataSourceLookup.getDataSource("java:app/jdbc/airlinesDS");
    }

}

当我启动我的应用程序时，我收到以下警告:

我的 persistence.xml:

    <?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>

    </properties>
  </persistence-unit>
</persistence>

如何使用JTA配置spring？上面的代码不好，因为当我尝试用简单的方法坚持时

    @Transactional
public void add() {
    User user = new User();
    user.setId(1L);
    user.setUsername("Jan");
    user.setPassword("abcd");
    entityManager.persist(user);
}

用户未保存。有人有 Spring JTA 配置的好例子吗？当然，我指的是基于 Java 类的配置。

Answer 1

添加此属性 <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>在 persistence.xml 文件中。
