我有一个dataSource,我使用Spring 3.0.3,Hibernate 3.5.1作为JPA提供程序,我使用MyBatis 3.0.2进行一些查询,我的应用程序在Tomcat 6上运行.我有一个HibernateDAO和一个MyBatisDAO,当我同时调用它们时从使用@Transactional注释的相同方法看起来它们不共享相同的事务,它们获得不同的连接.
我怎么能让他们这样做？

我已经尝试从DataSourceUtils.getConnection(dataSource)获取连接,我得到了MyBatis使用的连接,这很奇怪我认为问题出在MyBatis配置中,它不能使用JpaTransactionManager.甚至多次调用DataSoruceUtils.getConnection总是给出相同的连接,这没关系.

经过一些谷歌搜索后我尝试了spring-instrument-tomcat的类加载器(虽然我不知道tomcat是否真的使用它:))

部分applicationContext

<bean class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" id="dataSource">
    <property name="driverClassName" value="${database.driverClassName}"/>
    <property name="url" value="${database.url}"/>
    <property name="username" value="${database.username}"/>
    <property name="password" value="${database.password}"/>
</bean>

<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/>

<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
    <property name="dataSource" ref="dataSource"/>
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:META-INF/mybatis/mybatis-config.xml" />
</bean>

部分mybatis配置

<settings>
    <setting name="cacheEnabled" value="false" />
    <setting name="useGeneratedKeys" value="false" />
    <setting name="defaultExecutorType" value="REUSE" />
    <setting name="lazyLoadingEnabled" value="false"/>
</settings>

部分persistence.xml

<persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>

我有加入继承的实体：

支持者

@Entity
@Inheritance(strategy=InheritanceType.JOINED)
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "supporterType")
@JsonSubTypes({
    @JsonSubTypes.Type(value = PersonSupporterEntity.class, name = "PERSON"),
    @JsonSubTypes.Type(value = CompanySupporterEntity.class, name = "COMPANY")
})
@DiscriminatorColumn(name="supporter_type")
@Table(name = "supporter")
public class SupporterEntity extends UpdatableEntity {
    private long id;
    private SupporterType supporterType;
    private PartnerEntity partner;
...
}

个人支持者

@Entity
@DiscriminatorValue("PERSON")
@Table(name = "person_supporter")
public class PersonSupporterEntity extends SupporterEntity {
...
}

公司支持者

@Entity
@DiscriminatorValue("COMPANY")
@Table(name = "company_supporter")
public class CompanySupporterEntity extends SupporterEntity {
...
}

我有另一个引用 SupporterEntity 的实体

@Entity …

我们的代理程序崩溃了,我试图在Maven关闭时更新依赖关系.从那时起,我无法使用Maven下载任何内容.我得到这个错误的一切.我尝试了-U选项,删除我的本地存储库并尝试了不同的Maven版本(2.0.9,2.2.1),但它不起作用.不知道怎么解决这个问题？

此前它还说'存储库将被列入黑名单'给所有人.
