spring-jdbc：如何使用namedJdbcTemplate管理事务以对Oracle数据库执行CRUD

Question

As the following code, I use spring-jdbc to access Oracle db. I use namedJdbcTemplate to update and insert.

Now I want to manage transaction with DatasourceTransactionManager. What can I do to code this?

Dao code:

@Autowired
@Qualifier("svsJdbcTemplate")
JdbcTemplate jdbcTemplate;

protected NamedParameterJdbcTemplate namedJdbcTemplate;

private static final Logger logger = LoggerFactory
        .getLogger(DashboardDaoImpl.class);

@PostConstruct
public void setup() {
    namedJdbcTemplate = new NamedParameterJdbcTemplate(
            jdbcTemplate.getDataSource());
}

application-jdbc.xml configuration:

<bean id="svsJdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="svsDataSource"></property>
</bean>


<!-- JNDI Data Source -->
<bean id="svsDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<!-- 
    <property name="resourceRef" value="true" />
    <property name="jndiName" value="jdbc/svsDB" />
 -->
    <property name="jndiName" value="java:comp/env/jdbc/svsDB"/>
</bean>

<tx:annotation-driven proxy-target-class="true"
    transaction-manager="transactionManager" />

<!-- Creating TransactionManager Bean, since JDBC we are creating of type 
    DataSourceTransactionManager -->
<bean id="transactionManager"
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="svsDataSource" />
</bean>

Answer 1

In the spring config file replace

<bean id="svsJdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="svsDataSource"></property>
</bean>

with

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

and in the dao class autowire svsJdbcTemplate as follows.

@Autowired
NamedParameterJdbcTemplate  svsJdbcTemplate;

Now for managing the transactions use the @Transactional annotation in the service classes.
