spring tx事务实现

spring tx事务实现

anno 注解实现

在调用事务的类上 加上一个@Transactional注解

import com.zho.dao.IAccountDao;
import com.zho.domian.Account;
import com.zho.service.IAccountService;
import org.aspectj.lang.annotation.Around;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service("accountService")
@Transactional
public class AccountServiceImpl implements IAccountService {

    @Autowired
    private IAccountDao accountDao;



    @Override
    public Account findAccountById(int id) {
        return accountDao.findAccountById(id);

    }

    @Override
    public void transFor(String sourceName, String targetName, float money) {
        Account source = accountDao.findAccountByName(sourceName);
        Account target = accountDao.findAccountByName(targetName);
        source.setMoney(source.getMoney() + money);
        target.setMoney(target.getMoney() - money);
        accountDao.updateAccount(source);
//        int k = 1 / 0;
        accountDao.updateAccount(target);
        System.out.println("转账成功");
    }
}

创建一个事务类配置类

@Configuration
public class TransactionConfig {
	@Bean(name="transactionManager")
    public PlatformTransactionManager createTransactionManager(DataSource dataSource){
        return new DataSourceTransactionManager(dataSource);
    }
}

@Configuration
public class JdbcConfig {
    @Value("${jdbc.driver}")
    private String driver;
    @Value("${jdbc.url}")
    private String url;
    @Value("${jdbc.username}")
    private String username;
    @Value("${jdbc.password}")
    private String password;

    @Bean(name = "jdbcTemplate")
    public JdbcTemplate createJdbcTemplate(DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }

    @Bean(name="dataSource")
    public DataSource createDataSource() {
        DriverManagerDataSource ds = new DriverManagerDataSource();
        ds.setDriverClassName(driver);
        ds.setUrl(url);
        ds.setUsername(username);
        ds.setPassword(password);
        return ds;
    }
}

import org.springframework.context.annotation.*;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@ComponentScan("com.zho")
@Import({JdbcConfig.class,TransactionConfig.class})
@PropertySource("jdbcConfig.properties")
@EnableTransactionManagement
public class SpringConfiguration {
}

xml配置实现

还是需要一个事务配置 参数填充数据库源

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

配置通知

   <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED" read-only="false"/>
            <tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
        </tx:attributes>
    </tx:advice>

    <aop:config>
        <aop:pointcut id="pt" expression="execution(* com.zho.service.impl.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
    </aop:config>
