Spring_事务控制_动态代理
目录
二、使用动态代理在业务层来控制事务的提交和回滚，解决“转账”问题
三、通过 Spring中的 AOP 来解决上面的“转账”需求
一、“转账”需求引发的BUG
在前面我们实现了对单表的增删改查，我们现在有一个类似银行转账的需求，我们增加相应的代码：
1. 在 IAccountService 接口里面添加转账的方法
/**
* 转账
* @param sourceName 转出账户名称
* @param targetName 转入账户名称
* @param money 转账金额
*/
void transfer(String sourceName,String targetName,Float money);2. 在实现类 AccountServiceImpl 添加实现方法
@Override
public void transfer(String sourceName, String targetName, Float money) {
System.out.println("transfer....");
//2.1根据名称查询转出账户
Account source = accountDao.findAccountByName(sourceName);
//2.2根据名称查询转入账户
Account target = accountDao.findAccountByName(targetName);
//2.3转出账户减钱
source.setMoney(source.getMoney()-money);
//2.4转入账户加钱
target.setMoney(target.getMoney()+money);
//2.5更新转出账户
accountDao.updateAccount(source);
// int i=1/0;
//2.6更新转入账户
accountDao.updateAccount(target);
}
3. 在 IAccountDao 接口里面添加一个通过name来查找记录的方法
/**
* 根据名称查询账户
* @param accountName
* @return 如果有唯一的一个结果就返回，如果没有结果就返回null
* 如果结果集超过一个就抛异常
*/
Account findAccountByName(String accountName);4. 在实现类 AccountDaoImpl 里面实现方法
@Override
public Account findAccountByName(String accountName) {
try{
List<Account> accounts = runner.query("select * from account where name = ? ", new BeanListHandler<>(Account.class),accountName);
if(accounts == null || accounts.size() == 0){
return null;
}
if(accounts.size() > 1){
throw new RuntimeException("结果集不唯一，数据有问题");
}
return accounts.get(0);
}catch (Exception e) {
throw new RuntimeException(e);
}
}5. 在测试类 AccountServiceTest 里面添加测试方法
/**
* 测试转账功能
*/
@Test
public void testTransfer(){
as.transfer("aaa","bbb",100f);
}6. 运行 没错一切正常，aaa账户少的100，bbb账户增加了100，但是这些都是假象，如果我们的转账代码中间出现了异常程序终止，这样会造成数据的不一致。
7. 去掉 AccountServiceImpl 实现类里面的 int i=1/0; 注释，这个时候回发现aaa的钱确实少了，但是bbb的钱并没有加上去，这就是我们没有手动的控制事务的原因。
8. 我们的事务功能是开启了的，不然也不会执行前面的CRUT代码，产生失败的原因是事务被自动控制了。换言之，我们使用了 connection 对象的 setAutoCommit(true) 此方式控制事务，如果我们每次都执行一条 sql 语句，没有问题，但是如果业务方法一次要执行多条 sql 语句，这种方式就无法实现功能了。
二、使用动态代理在业务层来控制事务的提交和回滚，解决“转账”问题
解决前面的问题，我们需要让业务层来控制事务的提交和回滚，当我们执行时，由于执行有异常，转账失败。但是因为我们是每次执行持久层方法都是独立事务，导致无法实现事务控制（不符合事务的一致性）
这个时候我们一次完整的操作使用到的 Connection 应该是同一个，而不是像前面 AccountDaoImpl 类里面的 QueryRunner ，每次操作都是从连接池里面拿到的新的连接。
1、在 com.itheima.utils 包小创建两个工具类
我们使用 ThreadLocal 让同一个线程访问到的是同一个 Connection。
ConnectionUtils： 连接的工具类，它用于从数据源中获取一个连接，并且实现和线程的绑定
package com.itheima.utils;
import javax.sql.DataSource;
import java.sql.Connection;
/**
* 连接的工具类，它用于从数据源中获取一个连接，并且实现和线程的绑定
*/
public class ConnectionUtils {
private ThreadLocal<Connection> tl = new ThreadLocal<Connection>();
private DataSource dataSource;
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
/**
* 获取当前线程上的连接
*
* @return
*/
public Connection getThreadConnection() {
try {
//1.先从ThreadLocal上获取
Connection conn = tl.get();
//2.判断当前线程上是否有连接
if (conn == null) {
//3.从数据源中获取一个连接，并且存入ThreadLocal中
conn = dataSource.getConnection();
tl.set(conn);
}
//4.返回当前线程上的连接
return conn;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* 把连接和线程解绑
*/
public void removeConnection() {
tl.remove();
}
}
TransactionManager：和事务管理相关的工具类，它包含了，开启事务，提交事务，回滚事务和释放连接
package com.itheima.utils;
/**
* 和事务管理相关的工具类，它包含了，开启事务，提交事务，回滚事务和释放连接
*/
public class TransactionManager {
private ConnectionUtils connectionUtils;
public void setConnectionUtils(ConnectionUtils connectionUtils) {
this.connectionUtils = connectionUtils;
}
/**
* 开启事务
*/
public void beginTransaction() {
try {
connectionUtils.getThreadConnection().setAutoCommit(false);
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 提交事务
*/
public void commit() {
try {
connectionUtils.getThreadConnection().commit();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 回滚事务
*/
public void rollback() {
try {
connectionUtils.getThreadConnection().rollback();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 释放连接
*/
public void release() {
try {
connectionUtils.getThreadConnection().close();//还回连接池中
connectionUtils.removeConnection();
} catch (Exception e) {
e.printStackTrace();
}
}
}
注：由于我们是 web 应用，比如Tomcat 使用了连接池，和线程池技术，线程使用结束过后我们是要归还给Tomcat的这个时候我们需要把当前线程的Connection与线程解绑，不让后面程序拿到的线程里面有Connection 但是这个时候Connection已经关闭了，这是不可取的。
2、持久层实现 com.itheima.dao
package com.itheima.dao;
import com.itheima.domain.Account;
import java.util.List;
/**
* 账户的持久层接口
*/
public interface IAccountDao {
/**
* 查询所有
* @return
*/
List<Account> findAllAccount();
/**
* 查询一个
* @return
*/
Account findAccountById(Integer accountId);
/**
* 保存
* @param account
*/
void saveAccount(Account account);
/**
* 更新
* @param account
*/
void updateAccount(Account account);
/**
* 删除
* @param acccountId
*/
void deleteAccount(Integer acccountId);
/**
* 根据名称查询账户
* @param accountName
* @return 如果有唯一的一个结果就返回，如果没有结果就返回null
* 如果结果集超过一个就抛异常
*/
Account findAccountByName(String accountName);
}
实现类 com.itheima.dao.impl
package com.itheima.dao.impl;
import com.itheima.dao.IAccountDao;
import com.itheima.domain.Account;
import com.itheima.utils.ConnectionUtils;
import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.handlers.BeanHandler;
import org.apache.commons.dbutils.handlers.BeanListHandler;
import java.util.List;
/**
* 账户的持久层实现类
*/
public class AccountDaoImpl implements IAccountDao {
private QueryRunner runner;
private ConnectionUtils connectionUtils;
public void setRunner(QueryRunner runner) {
this.runner = runner;
}
public void setConnectionUtils(ConnectionUtils connectionUtils) {
this.connectionUtils = connectionUtils;
}
@Override
public List<Account> findAllAccount() {
try{
return runner.query(connectionUtils.getThreadConnection(),"select * from account",new BeanListHandler<Account>(Account.class));
}catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public Account findAccountById(Integer accountId) {
try{
return runner.query(connectionUtils.getThreadConnection(),"select * from account where id = ? ",new BeanHandler<Account>(Account.class),accountId);
}catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public void saveAccount(Account account) {
try{
runner.update(connectionUtils.getThreadConnection(),"insert into account(name,money)values(?,?)",account.getName(),account.getMoney());
}catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public void updateAccount(Account account) {
try{
runner.update(connectionUtils.getThreadConnection(),"update account set name=?,money=? where id=?",account.getName(),account.getMoney(),account.getId());
}catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public void deleteAccount(Integer accountId) {
try{
runner.update(connectionUtils.getThreadConnection(),"delete from account where id=?",accountId);
}catch (Exception e) {
throw new RuntimeException(e);
}
}
@Override
public Account findAccountByName(String accountName) {
try{
List<Account> accounts = runner.query(connectionUtils.getThreadConnection(),"select * from account where name = ? ",new BeanListHandler<Account>(Account.class),accountName);
if(accounts == null || accounts.size() == 0){
return null;
}
if(accounts.size() > 1){
throw new RuntimeException("结果集不唯一，数据有问题");
}
return accounts.get(0);
}catch (Exception e) {
throw new RuntimeException(e);
}
}
}
3、业务层 com.itheima.service
package com.itheima.service;
import com.itheima.domain.Account;
import java.util.List;
/**
* 账户的业务层接口
*/
public interface IAccountService {
/**
* 查询所有
* @return
*/
List<Account> findAllAccount();
/**
* 查询一个
* @return
*/
Account findAccountById(Integer accountId);
/**
* 保存
* @param account
*/
void saveAccount(Account account);
/**
* 更新
* @param account
*/
void updateAccount(Account account);
/**
* 删除
* @param acccountId
*/
void deleteAccount(Integer acccountId);
/**
* 转账
* @param sourceName 转出账户名称
* @param targetName 转入账户名称
* @param money 转账金额
*/
void transfer(String sourceName,String targetName,Float money);
//void test();//它只是连接点，但不是切入点，因为没有被增强
}
IAccountService 接口的实现类里面我们先写一个代码量大的实现
package com.itheima.service.impl;
import com.itheima.dao.IAccountDao;
import com.itheima.domain.Account;
import com.itheima.service.IAccountService;
import com.itheima.utils.TransactionManager;
import java.util.List;
/**
* 账户的业务层实现类
*
* 事务控制应该都是在业务层
*/
public class AccountServiceImpl_OLD implements IAccountService{
private IAccountDao accountDao;
private TransactionManager txManager;
public void setTxManager(TransactionManager txManager) {
this.txManager = txManager;
}
public void setAccountDao(IAccountDao accountDao) {
this.accountDao = accountDao;
}
@Override
public List<Account> findAllAccount() {
try {
//1.开启事务
txManager.beginTransaction();
//2.执行操作
List<Account> accounts = accountDao.findAllAccount();
//3.提交事务
txManager.commit();
//4.返回结果
return accounts;
}catch (Exception e){
//5.回滚操作
txManager.rollback();
throw new RuntimeException(e);
}finally {
//6.释放连接
txManager.release();
}
}
@Override
public Account findAccountById(Integer accountId) {
try {
//1.开启事务
txManager.beginTransaction();
//2.执行操作
Account account = accountDao.findAccountById(accountId);
//3.提交事务
txManager.commit();
//4.返回结果
return account;
}catch (Exception e){
//5.回滚操作
txManager.rollback();
throw new RuntimeException(e);
}finally {
//6.释放连接
txManager.release();
}
}
@Override
public void saveAccount(Account account) {
try {
//1.开启事务
txManager.beginTransaction();
//2.执行操作
accountDao.saveAccount(account);
//3.提交事务
txManager.commit();
}catch (Exception e){
//4.回滚操作
txManager.rollback();
}finally {
//5.释放连接
txManager.release();
}
}
@Override
public void updateAccount(Account account) {
try {
//1.开启事务
txManager.beginTransaction();
//2.执行操作
accountDao.updateAccount(account);
//3.提交事务
txManager.commit();
}catch (Exception e){
//4.回滚操作
txManager.rollback();
}finally {
//5.释放连接
txManager.release();
}
}
@Override
public void deleteAccount(Integer acccountId) {
try {
//1.开启事务
txManager.beginTransaction();
//2.执行操作
accountDao.deleteAccount(acccountId);
//3.提交事务
txManager.commit();
}catch (Exception e){
//4.回滚操作
txManager.rollback();
}finally {
//5.释放连接
txManager.release();
}
}
@Override
public void transfer(String sourceName, String targetName, Float money) {
try {
//1.开启事务
txManager.beginTransaction();
//2.执行操作
//2.1根据名称查询转出账户
Account source = accountDao.findAccountByName(sourceName);
//2.2根据名称查询转入账户
Account target = accountDao.findAccountByName(targetName);
//2.3转出账户减钱
source.setMoney(source.getMoney()-money);
//2.4转入账户加钱
target.setMoney(target.getMoney()+money);
//2.5更新转出账户
accountDao.updateAccount(source);
int i=1/0;
//2.6更新转入账户
accountDao.updateAccount(target);
//3.提交事务
txManager.commit();
}catch (Exception e){
//4.回滚操作
txManager.rollback();
e.printStackTrace();
}finally {
//5.释放连接
txManager.release();
}
}
}
显而可见前面类的实现重复代码太多，不利于我们后期的维护，这里我们使用动态代理来解决上面的问题，增强的代码我们提取出来。
package com.itheima.service.impl;
import com.itheima.dao.IAccountDao;
import com.itheima.domain.Account;
import com.itheima.service.IAccountService;
import java.util.List;
/**
* 账户的业务层实现类
*
* 事务控制应该都是在业务层
*/
public class AccountServiceImpl implements IAccountService{
private IAccountDao accountDao;
public void setAccountDao(IAccountDao accountDao) {
this.accountDao = accountDao;
}
@Override
public List<Account> findAllAccount() {
return accountDao.findAllAccount();
}
@Override
public Account findAccountById(Integer accountId) {
return accountDao.findAccountById(accountId);
}
@Override
public void saveAccount(Account account) {
accountDao.saveAccount(account);
}
@Override
public void updateAccount(Account account) {
accountDao.updateAccount(account);
}
@Override
public void deleteAccount(Integer acccountId) {
accountDao.deleteAccount(acccountId);
}
@Override
public void transfer(String sourceName, String targetName, Float money) {
System.out.println("transfer....");
//2.1根据名称查询转出账户
Account source = accountDao.findAccountByName(sourceName);
//2.2根据名称查询转入账户
Account target = accountDao.findAccountByName(targetName);
//2.3转出账户减钱
source.setMoney(source.getMoney()-money);
//2.4转入账户加钱
target.setMoney(target.getMoney()+money);
//2.5更新转出账户
accountDao.updateAccount(source);
// int i=1/0;
//2.6更新转入账户
accountDao.updateAccount(target);
}
}
4、创建Service的代理对象的工厂
com.itheima.factory
package com.itheima.factory;
import com.itheima.service.IAccountService;
import com.itheima.utils.TransactionManager;
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;
/**
* 用于创建Service的代理对象的工厂
*/
public class BeanFactory {
//1.定义被代理对象
private IAccountService accountService;
private TransactionManager txManager;
public void setTxManager(TransactionManager txManager) {
this.txManager = txManager;
}
public final void setAccountService(IAccountService accountService) {
this.accountService = accountService;
}
/**
* 获取Service代理对象
* @return
*/
public IAccountService getAccountService() {
return (IAccountService)Proxy.newProxyInstance(accountService.getClass().getClassLoader(),
accountService.getClass().getInterfaces(),
new InvocationHandler() {
/**
* 添加事务的支持
*
* @param proxy
* @param method
* @param args
* @return
* @throws Throwable
*/
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
if("test".equals(method.getName())){
return method.invoke(accountService,args);
}
Object rtValue = null;
try {
//1.开启事务
txManager.beginTransaction();
//2.执行操作
rtValue = method.invoke(accountService, args);
//3.提交事务
txManager.commit();
//4.返回结果
return rtValue;
} catch (Exception e) {
//5.回滚操作
txManager.rollback();
throw new RuntimeException(e);
} finally {
//6.释放连接
txManager.release();
}
}
});
}
}
注：这里我没没有写贴ben对象的代码和pom.xml，复制前面连接里面的代码即可。
5、测试代码
import com.itheima.service.IAccountService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
/**
* 使用Junit单元测试：测试我们的配置
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:bean.xml")
public class AccountServiceTest {
@Autowired
@Qualifier("proxyAccountService")
private IAccountService as;
@Test
public void testTransfer(){
as.transfer("aaa","bbb",100f);
}
}
bean.xml
现在我们在配置 QueryRunner 的时候我们就不会注入数据源了，这个时候的Connection 是通过ConnectionUtils 获取，所有在dao层我们需要传入一个Connection。

<!-- 注入ConnectionUtils -->
<property name="connectionUtils" ref="connectionUtils"/>
</bean>
</beans>三、通过 Spring中的 AOP 来解决上面的“转账”需求
1. 工具类我们这里依然需要
com.itheima.utils
package com.itheima.utils;
import javax.sql.DataSource;
import java.sql.Connection;
/**
* 连接的工具类，它用于从数据源中获取一个连接，并且实现和线程的绑定
*/
public class ConnectionUtils {
private ThreadLocal<Connection> tl = new ThreadLocal<Connection>();
private DataSource dataSource;
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
/**
* 获取当前线程上的连接
*/
public Connection getThreadConnection() {
try{
//1.先从ThreadLocal上获取
Connection conn = tl.get();
//2.判断当前线程上是否有连接
if (conn == null) {
//3.从数据源中获取一个连接，并且存入ThreadLocal中
conn = dataSource.getConnection();
tl.set(conn);
}
//4.返回当前线程上的连接
return conn;
}catch (Exception e){
throw new RuntimeException(e);
}
}
/**
* 把连接和线程解绑
*/
public void removeConnection(){
tl.remove();
}
}
package com.itheima.utils;
/**
* 和事务管理相关的工具类，它包含了，开启事务，提交事务，回滚事务和释放连接
*/
public class TransactionManager {
private ConnectionUtils connectionUtils;
public void setConnectionUtils(ConnectionUtils connectionUtils) {
this.connectionUtils = connectionUtils;
}
/**
* 开启事务
*/
public void beginTransaction(){
try {
connectionUtils.getThreadConnection().setAutoCommit(false);
}catch (Exception e){
e.printStackTrace();
}
}
/**
* 提交事务
*/
public void commit(){
try {
connectionUtils.getThreadConnection().commit();
}catch (Exception e){
e.printStackTrace();
}
}
/**
* 回滚事务
*/
public void rollback(){
try {
connectionUtils.getThreadConnection().rollback();
}catch (Exception e){
e.printStackTrace();
}
}
/**
* 释放连接
*/
public void release(){
try {
connectionUtils.getThreadConnection().close();//还回连接池中
connectionUtils.removeConnection();
}catch (Exception e){
e.printStackTrace();
}
}
}
2. 业务层代码
package com.itheima.service;
import com.itheima.domain.Account;
import java.util.List;
/**

*/
public interface IAccountService {
/**

*/
void transfer(String sourceName,String targetName,Float money);
//void test();//它只是连接点，但不是切入点，因为没有被增强
}
package com.itheima.service.impl;
import com.itheima.dao.IAccountDao;
import com.itheima.domain.Account;
import com.itheima.service.IAccountService;
import java.util.List;
/**

* 事务控制应该都是在业务层
*/
public class AccountServiceImpl implements IAccountService{
private IAccountDao accountDao;
public void setAccountDao(IAccountDao accountDao) {
this.accountDao = accountDao;
}
//@Override
public List<Account> findAllAccount() {

}
// @Override

System.out.println("transfer....");
//2.1根据名称查询转出账户
Account source = accountDao.findAccountByName(sourceName);
//2.2根据名称查询转入账户
Account target = accountDao.findAccountByName(targetName);
//2.3转出账户减钱

//2.5更新转出账户

}
}
3. dao层代码
