java组织。springframework。刀。InvalidDataAccessApiUsageException:在只读模式下不允许执行写入操作

1 周，6 日 Questions & Answers 4837

我是SSH新手，使用的是Spring4、Hibernate4和Struts2。当我为一个DAO类创建一个单元测试时，我遇到了这个异常

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:testApplicationContext.xml"})
public class UserDaoTest {
    @Test
    public void testAddUserNotExists() {
        User user = new User("20116524", "785ee107c11dfe36de668b1ae7baacbb");
        userDao.addUser(user);

        assertNotNull(userDao.getUserByUsername("20116524"));
    }

    @Autowired
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

    /**
     * UserDao object to test.
     */
    private UserDao userDao;
}

我试图在web.xml中添加以下行，但不起作用

Reference: Java / Hibernate - Write operations are not allowed in read-only mode

我相信我的applicationContext.xml有问题，以下是内容：

<!-- Session Factory -->
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
        </props>
    </property>
    <property name="packagesToScan">
        <list>
            <value>emis.accounts.model</value>
        </list>
    </property>
</bean>
<!-- Transaction -->
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

没有关于AOP和tx:advice的配置。因此，我尝试添加一些行：

<!-- Transaction -->
<bean id="transactionManager"
    class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:advice id="txAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="*" propagation="REQUIRED" read-only="true"/>
        <tx:method name="get*" propagation="REQUIRED" read-only="true" />
        <tx:method name="find*" propagation="REQUIRED" read-only="true" />
        <tx:method name="list*" propagation="REQUIRED" read-only="true" />
        <tx:method name="load*" propagation="REQUIRED" read-only="true" />
        <tx:method name="save*" propagation="REQUIRED" rollback-for="Exception" />
        <tx:method name="add*" propagation="REQUIRED" rollback-for="Exception" />
        <tx:method name="save" propagation="REQUIRED" rollback-for="Exception" />
        <tx:method name="update*" propagation="REQUIRED" rollback-for="Exception" />
        <tx:method name="update" propagation="REQUIRED" rollback-for="Exception" />
        <tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception" />
        <tx:method name="delete" propagation="REQUIRED" rollback-for="Exception" />
        <tx:method name="*" propagation="REQUIRED" />
    </tx:attributes>
</tx:advice>

<aop:aspectj-autoproxy />
<aop:config>
    <aop:pointcut id="aopPointcut"
        expression="execution(* emis.*.service.*.*(..))" />
    <aop:advisor advice-ref="txAdvice" pointcut-ref="aopPointcut"/>
</aop:config>

不过，我还有一个例外：

我该怎么办？有人能帮我吗？非常感谢
