Question

好吧，我在论坛中查看了与我的问题相关的所有问题，但我无法解决我的问题。所以我向任何能帮我解决问题的人寻求帮助。

如果一切都在不使用@Transactional注释的情况下工作，但是我想让它以这种方式工作，等待评论。

这是我的persistence.xml：

    <persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">
    <!-- Persistence Unit -->
    <persistence-unit name="databaseEstoque" transaction-type="RESOURCE_LOCAL">
        <!-- Implements to JPA, in this case Hibernate -->
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <!-- Here you can see all entities -->
        <class>com.systemhaus.examples.domain.Produto</class>
        <class>com.systemhaus.examples.domain.Gaveta</class>
        <class>com.systemhaus.examples.domain.AbstractOperacao</class>
        <class>com.systemhaus.examples.domain.AdicionaQuantidade</class>
        <class>com.systemhaus.examples.domain.RetiraQuantidade</class>

        <properties>
            <!-- JDBC properties -->

            <!-- Hibernate specific settings -->
            <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true" />
        </properties>
    </persistence-unit>
</persistence>

这是我的applicationContext.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"

    </bean>

    <bean id="estoque" class="com.systemhaus.examples.domain.Estoque">
        <constructor-arg ref="estoqueRepositoryDB" />
    </bean>

    <bean id="estoqueRepositoryDB"

        <property name="username" value="Paulo" />
        <property name="password" value="1" />
    </bean>

</beans>

这是我的方法：

private EntityManagerFactory emf;

    @PersistenceUnit
    public void setEntityManagerFactory(EntityManagerFactory emf) {
        this.emf = emf;
    }

    @Override
    @Transactional
    public void saveGaveta(Gaveta gaveta) {
        EntityManager em = emf.createEntityManager();
        em.persist(gaveta);
        em.flush();
    }

我能够解决我的问题，碰巧这是我第一次创建Maven项目。所以我已经在我的lib中导入了JAR，但我使用的是pom.xml，即使我正在更改我的pom.xml依赖项，他也使用从我的lib导入的类，我的解决方案是清理已编译的内容并从lib中删除所有JARS并在pom.xml中添加依赖项。
