Question

在对部署在Tomcat上的Web服务进行插入操作时，我面临以下异常

javax.persistence.TransactionRequiredException：否EntityManager具有当前线程可用的实际事务-无法可靠地处理“持续”呼叫

我的spring-jpa.xml如下

<?xml version="1.0" encoding="UTF-8"?>

    <!-- ========================= RESOURCE DEFINITIONS ========================= -->

    <!-- Activates a load-time weaver for the context. Any bean within the context that implements LoadTimeWeaverAware 
        (such as LocalContainerEntityManagerFactoryBean) will receive a reference to the autodetected load-time weaver. -->



    <context:load-time-weaver aspectj-weaving="on" weaver-class="org.springframework.instrument.classloading.tomcat.TomcatLoadTimeWeaver" />



    <bean id="entityManagerFactoryReadOnly" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="ReadOnlyBasePersistenceUnit" />
    </bean>

    <bean id="entityManagerFactoryReadWrite" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="ReadWriteBasePersistenceUnit" />
    </bean>

    <bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter" />

        <property name="entityManagerFactory" ref="entityManagerFactoryReadOnly" />
        <property name="defaultTimeout" value="90" />
    </bean>

    <bean id="transactionManagerReadWrite" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactoryReadWrite" />
        <property name="defaultTimeout" value="90" />
    </bean>


    <!-- ========================= BUSINESS OBJECT DEFINITIONS ========================= -->

    <!-- Instruct Spring to perform declarative transaction management automatically on annotated classes. -->
    <tx:annotation-driven mode="aspectj" transaction-manager="transactionManagerReadWrite"/>
    <tx:annotation-driven mode="aspectj" transaction-manager="transactionManagerReadOnly"/>

    <!-- Post-processor to perform exception translation on @Repository classes (from native exceptions such 
         as JPA PersistenceExceptions to Spring's DataAccessException hierarchy). -->
    <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />

</beans>

dependecncies.gradle如下

    compile (
        'commons-lang:commons-lang:2.2',
        'javax.xml:jsr173:1.0',
        'commons-httpclient:commons-httpclient:3.1',
        'javax.servlet:servlet-api:2.5',
        'regexp:regexp:1.3',

        'javax.persistence:javax.persistence-api:2.2',
        'org.eclipse.persistence:eclipselink:2.5.2' 
}

服务类别如下

class Facade impelments Ifacade {
@Autowired

@Override
@Transactional
public CreateRequestResponse createRequests(List<BusinnessObject> bobject) {
          this.dao.createRequests(bobject)
} 

}
