Question

我正在使用Spring Transaction进行一些测试，这是我的配置：

DAO

@Repository
public class ClienteDaoJdbc implements ClienteDao {

private static final String SQL_INSERT = "INSERT INTO clientes (CodigoCliente,Nombres) "
                    + "VALUES (:codigo_cliente,:nombres)";

@Autowired
private NamedParameterJdbcTemplate jdbcTemplate;

public void insertBatch(List<Cliente> clientes) {
    Map<String, Object>[] batchValues = new HashMap[clientes.size()];
    for (int i = 0; i < batchValues.length; i++) {
        Map<String, Object> parametros = new HashMap<String, Object>();
        parametros.put("codigo_cliente", clientes.get(i).getCodigoCliente());
        parametros.put("nombres", clientes.get(i).getNombres());
        batchValues[i] = parametros;
    }
    this.jdbcTemplate.batchUpdate(SQL_INSERT, batchValues);
    }
}

服务

@Service
@Transactional(readOnly=true)
public class ClienteServiceImpl implements ClienteService {

    @Autowired
    private ClienteDao clienteDao;

    @Transactional(readOnly=false,propagation=Propagation.REQUIRES_NEW)
    public void register(List<Cliente> clientes) {
        this.clienteDao.insertBatch(clientes);
    }

}

春季配置

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/test"/>
        <property name="username" value="root"/>
        <property name="password" value=""/>
        <property name="defaultAutoCommit" value="false"/>
    </bean>

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">
        <constructor-arg ref="dataSource"/>
    </bean>

    <context:component-scan base-package="com.varas"/>

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <context:annotation-config/>

    <tx:annotation-driven/>

当我在独立的应用程序中使用此代码时，事务工作非常完美，为此我使用了一些代码来测试这个应用程序而且我得到了：

DEBUG: org.springframework.jdbc.datasource.DataSourceTransactionManager - Rolling back JDBC transaction on Connection [ProxyConnection[PooledConnection[com.mysql.jdbc.JDBC4Connection@1a10a9a1]]]
DEBUG: org.springframework.jdbc.datasource.DataSourceTransactionManager - Releasing JDBC Connection [ProxyConnection[PooledConnection[com.mysql.jdbc.JDBC4Connection@1a10a9a1]]] after transaction

回滚过程有效，但是当我在Spring MVC项目中使用相同的代码时，Spring事务显然无效并且回滚过程永远不会发生

我不知道为什么在这种情况下，在We App环境中，Spring Transaction不起作用？提前感谢您的回复。
