Hibernate对Spring-WS无响应

Question

我有一个单上下文的Spring-WS应用程序（也就是说，我的项目中只有一个文件包含定义），即something-servlet.xml。 当我通过DAO调用persist时，数据库中没有创建任何条目。 我也没有抛出任何异常。

如果我遗漏了更多有助于确定问题的信息，请告诉我。 谢谢。

一些-servlet.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:sws="http://www.springframework.org/schema/web-services"

    <sws:annotation-driven />

    <sws:dynamic-wsdl id="manager" portTypeName="AbcDirect"
        locationUri="/mailerManagerService/" targetNamespace="http://ecsdfsds.com/direct/definitions">
        <sws:xsd location="/WEB-INF/mailManagerRequest.xsd" />
    </sws:dynamic-wsdl>

    <bean id="mailServerPersistenceManager"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="directMailDataSource" />
        <property name="packagesToScan" value="com.abc.direct.mailserver.dao"/>
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
        </property>
    </bean>

    <bean id="directMailDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <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>
</beans>

道类：

@Entity
@Table(name="virtualusertable")
public class VirtualUser {

    @Id
    @Column(name="user")
    private String user;
//  private String domain;
//  private String targetAddress;

    public VirtualUser(String username) {
        this.user = username;
    }

    public String getUser() {
        return user;
    }

    public void setUser(String user) {
        this.user = user;
    }
}

---

@Component
public class VirtualUsers {

    @PersistenceContext
    EntityManager entityManager;

    public void save(VirtualUser user) {
        this.entityManager.persist(user);
    }

    public void setEntityManager(EntityManager entityManager) {
        this.entityManager = entityManager;
    }
}

终点：

@Endpoint
public class MailManagerEndpoint {

    private static final String NAMESPACE_URI = "http://asfsdfs.com/direct/schemas";
    static final Namespace NAMESPACE = Namespace.getNamespace(NAMESPACE_URI);

    private MailManagerService service;
    @Autowired
    private VirtualUsers virtualUsers;

    @Autowired
    public MailManagerEndpoint(MailManagerService mailManagerService) {

        this.service = mailManagerService;
    }

    @PayloadRoot(namespace = NAMESPACE_URI, localPart = "MailManagerRequest")
    public @ResponsePayload Element handleRequest(@RequestPayload Element element) throws JDOMException, IOException {

        VirtualUser user = new VirtualUser("newuser");
        virtualUsers.save(user);

        return new Element("success");
    }
}

在启动日志中，我真的很好奇为什么此块会重复7次：

更新：添加@Transactional和后，persist（）输出：

如果要将数据插入数据库，则需要进行事务处理。 为了让Spring提供事务，您需要将<tx:annotation-driven />放置到Spring上下文文件中，并在将数据插入DB的方法上放置@Transactional注释。 这样，Spring将在方法执行开始时为您启动事务，并在方法执行结束时将其提交（如果抛出异常，则将其回滚）。
