SSM整合

Spring数据源配置
resources/spring/spring-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mybatis="http://mybatis.org/schema/mybatis-spring"

</beans>

1 测试数据库连通性
test/java/common/TestDataBase.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/spring/spring-mybatis.xml")
public class TestDataBase {
    @Autowired
    @Qualifier("dataSource")
    private BasicDataSource dataSource;
  //测试数据库连通性
    @Test
    public void testDataBase() throws SQLException {
        //返回的是java.sql.Connection
        Connection connection = dataSource.getConnection();
        PreparedStatement preparedStatement = connection.prepareStatement("SELECT * from category");
        ResultSet resultSet = preparedStatement.executeQuery();
        while (resultSet.next()){
            System.out.println(resultSet.getInt("id"));
            System.out.println(resultSet.getString("kind"));
        }
    }
}

整合Spring和MyBatis

public interface AccountDao {
    Account selectByAccount(String account);
    int insertAccount(Account account);
}

@Alias("account") 
public class Account {
    private String account;
    private String password;

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

    </select>
    <insert id="insertAccount">
        INSERT INTO account (account,password) VALUES (#{account},#{password})

        <property name="sqlSessionFactoryBeanName" value="sessionFactory"/>
        <property name="basePackage" value="com.fyh.blog.manager.*.dao"/>
    </bean>

测试MyBatis
/test/com/fyh/blog/manager/login/dao/TestAccountDao.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:/spring/spring-mybatis.xml")
public class TestAccountDao {
    @Autowired

    @Test
    public void testMyBatis(){
        Account account =  accountDao.selectByAccount("admin");
        System.out.println(account.getAccount() + "," + account.getPassword());
    }
}

事务配置

        account.setAccount("123");
        accountDao.insertAccount(account);
        throw new Exception("出错");
    }
}

测试事务
