3. 配置数据库
   resources/database/jdbc.properties

mysql.driverClass=com.mysql.jdbc.Driver
mysql.url=地址
mysql.user=用户名
mysql.password=密码

SSM整合

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

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

1. Dao,Mappper,Domain
   com/fyh/blog/manager/login/dao/AccountDao.java

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

com/fyh/blog/manager/login/domain/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;
    }
}

/resources/mapper/AccountMapper.xml

    
        SELECT * FROM account WHERE account=#{account}
    
    
        INSERT INTO account (account,password) VALUES (#{account},#{password})
    

2. 整合配置
   resources/spring/spring-mybatis.xml

  
  
        
        
        
            
                com.fyh.blog.manager.login.domain.Account
            
        
    
     
    
        
        
    

3. 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
    private AccountDao accountDao;

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

事务配置

1. Spring配置文件
   resources/spring/spring-mybatis.xml

2. service
   com/fyh/blog/manager/login/service/impl/LoginServiceImpl .java

@Service
public class LoginServiceImpl implements LoginService{

    @Autowired
    private AccountDao accountDao;

    public void insertAccount() throws Exception {
        Account account = new Account();
        account.setPassword("23");
        account.setAccount("123");
        accountDao.insertAccount(account);
        throw new Exception("出错");
    }
}

3. 测试事务
   /test/com/fyh/blog/manager/login/service/TestLoginService.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:/spring/spring-mybatis.xml")
public class TestLoginService {
    @Autowired
    private LoginService loginService;
    @Test
    public void insertAccount() throws Exception {
        loginService.insertAccount();
    }
}

spring-mvc配置

1. 配置文件
   resources/spring-mvc/spring-mvc.xml

2. controller
   /com/fyh/blog/manager/login/action/LoginAction.java

@Controller
public class LoginAction {
    @RequestMapping("dd")
    public String dd(Model model) {
        model.addAttribute("1", "2");
        return "dd";
    }
}

3. 测试
   /test/com/fyh/blog/manager/login/action/TestLoginService.java

@RunWith(SpringJUnit4ClassRunner.class) //表示使用什么测试环境进行测试
@WebAppConfiguration
@ContextConfiguration(locations = {"classpath:/spring/spring-mybatis.xml", "classpath:/spring-mvc/spring-mvc.xml"})
public class TestLoginService {
    @Autowired
    WebApplicationContext webApplicationContext;
    //虚拟MVC请求，获取得到处理结果
    MockMvc mockMvc;

    @Before
    public void initMockMvc() {
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void testPage() throws Exception {
       MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/dd")).andReturn();
        MockHttpServletRequest request = mvcResult.getRequest();
        String s = (String) request.getAttribute("1");
        assert s.equals("2");
    }
}

配置web.xml

    
    
        contextConfigLocation
        classpath:spring/spring-mybatis.xml
    
    
    
        org.springframework.web.context.ContextLoaderListener
    

    
    
        encodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            UTF-8
        
    
    
        encodingFilter
        /*
    

    
    
        tt
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:spring-mvc/spring-mvc.xml
        
        1
    
    
        tt
        /
