JDBC Connection ill not be managed by Spring

JDBC Connection不会被Spring管理的原因可能是因为事务同步未激活。可以通过检查日志来验证是否配置全面。如果日志中出现类似于“SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@4b8729ff] was not registered for synchronization because synchronization is not active JDBC Connection [com.mysql.jdbc.JDBC4Connection@37fb0bed] will not be managed by Spring”的信息,则说明事务同步未激活。此时,JDBC Connection将不会被Spring管理。可以通过激活事务同步来解决这个问题。

程序报错:jdbcconnection will not be managed by spring
This error message typically occurs when you are using Spring framework to manage database connections, but the JDBC connection is not being properly managed by Spring.
To resolve this issue, you need to make sure that you are using the correct Spring JDBC templates and that you have properly configured your data source. Here are some steps that you can follow to fix this error:
1. Make sure that you are using the correct Spring JDBC templates. Depending on your project setup, you may need to use either the JdbcTemplate or NamedParameterJdbcTemplate.
2. Ensure that you have properly configured your data source. You can do this by defining a DataSource bean in your Spring configuration file and setting the necessary properties (e.g. URL, username, password, etc.).
3. Make sure that you are using the correct transaction management settings. If you are using Spring's declarative transaction management, make sure that you have properly annotated your service methods with the @Transactional annotation.
4. Check your code for any manual creation or management of JDBC connections. This can interfere with Spring's management of database connections and cause the error message.
By following these steps, you should be able to resolve the "jdbcconnection will not be managed by spring" error and properly manage your database connections using Spring.
JDBC Connection will be managed by Spring
是的,JDBC Connection可以通过Spring进行管理。具体实现方法如下:
1.在dispatcher-servlet.xml文件中添加以下代码,开启事务管理:
```xml
<tx:annotation-driven transaction-manager="transactionManager" />
```
2.在applicationContext.xml文件中配置以下代码,创建DataSourceTransactionManager对象:
```xml
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
```
3.在需要使用JDBC Connection的类中,使用@Autowired注解将DataSourceTransactionManager对象注入进来,然后使用@Transactional注解开启事务管理:
```java
@Autowired
private DataSourceTransactionManager transactionManager;
@Transactional
public void doSomething() {
// 在这里使用JDBC Connection进行数据库操作
}
```
这样就可以通过Spring管理JDBC Connection了。
