1.手动配置事务的方式是

applicationContext.xml

 

dao层（接口类这里不写）

package com.test.spring.aop.tansation.example.dao;import org.springframework.jdbc.core.support.JdbcDaoSupport;public class AccountDaoImpl extends JdbcDaoSupport implements AccountDao {    public void in(String inner, int money) {        this.getJdbcTemplate().update("update account set money = money -? where username = ?", money, inner);    }    public void out(String outter, int money) {        this.getJdbcTemplate().update("update account set money = money +? where username = ?", money, outter);    }}

 

service层

package com.test.spring.aop.tansation.example.service;import org.springframework.transaction.TransactionStatus;import org.springframework.transaction.support.TransactionCallbackWithoutResult;import org.springframework.transaction.support.TransactionTemplate;import com.test.spring.aop.tansation.example.dao.AccountDao;public class AccountServiceImpl implements AccountService {    private AccountDao accountDao;    private TransactionTemplate transactionTemplate;        public void setAccountDao(AccountDao accountDao) {        this.accountDao = accountDao;    }    public void setTransactionTemplate(TransactionTemplate transactionTemplate) {        this.transactionTemplate = transactionTemplate;    }            public void tansfer(final String inner, final String outter, final int money) {                //手动方式配置        transactionTemplate.execute(new TransactionCallbackWithoutResult() {                        @Override            protected void doInTransactionWithoutResult(TransactionStatus status) {                accountDao.out(outter, money); 　　　　　　　　　　//遇到异常时，事务回滚                int i = 1/0;                accountDao.in(inner, money);                            }        });            }}

 

测试

package com.test.spring.aop.tansation.example;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.test.spring.aop.tansation.example.service.AccountService;public class TestExample {    @Test    public void test() {        ApplicationContext ctx = new ClassPathXmlApplicationContext("com/test/spring/aop/tansation/example/applicationContext.xml");            AccountService as = ctx.getBean("accountService",AccountService.class);                as.tansfer("jack", "peter", 200);    }}

 

2.半自动，使用代理的方式

这里只需要修改一下service层和配置就可以了

 

applicationContext.xml

 

service层

package com.test.spring.aop.tansation.example.service;import org.springframework.transaction.TransactionStatus;import org.springframework.transaction.support.TransactionCallbackWithoutResult;import org.springframework.transaction.support.TransactionTemplate;import com.test.spring.aop.tansation.example.dao.AccountDao;public class AccountServiceImpl implements AccountService {    private AccountDao accountDao;    private TransactionTemplate transactionTemplate;        public void setAccountDao(AccountDao accountDao) {        this.accountDao = accountDao;    }    public void setTransactionTemplate(TransactionTemplate transactionTemplate) {        this.transactionTemplate = transactionTemplate;    }            public void tansfer(final String inner, final String outter, final int money) {
                    accountDao.out(outter, money);        int i = 1/0;        accountDao.in(inner, money);    }}

 

3. 使用spring自动的方式

根据上面的一大串配置，会是很头疼，现在就是用全自动，简化上面繁琐的配置，除了修改配置外，其余的都不需要修改
