  </dependencies>

注意：

Maven项目中，如果源代码(src/main/java)存在xml、properties、tld 等文件，Maven默认不会自动编译该文件到输出目录,如果要编译源代码中xml properties tld 等文件需要显式配置resources 标签

<build>
    <finalName>ssm</finalName>
    <resources>
      <resource>
        <directory>src/main/resources</directory>
      </resource>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.xml</include>
          <include>**/*.properties</include>
          <include>**/*.tld</include>
        </includes>
        <filtering>false</filtering>
      </resource>
    </resources>
   </build>

三、添加Spring框架

1.配置spring.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:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!--开启注解扫描，只扫描处理service和dao，controller不需要Spring框架扫描处理-->
    <context:component-scan base-package="cn.ybzy" >
        <!--配置那种类型注解不扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>
</beans>

2.注解配置Service层、Dao层

Account 实体类

public class Account implements Serializable{

    private Integer id;
    private String name;
    private Double money;
    //getter() setter()
}

AccountDao接口与AccountDaoImpl实现类

public interface AccountDao {
	
	void save(Account account);
	
	List<Account> findAll();
}

@Repository("accountDao")
public class AccountDaoImpl implements IAccountDao {

	@Override
	public List<Account> findAllAccount() {
	System.out.println("Dao查询所有账户...");
	return null;
	}
	@Override
	public void saveAccount(Account account) {
	System.out.println("Dao保存账户...");
	}
}

AccountService接口与AccountServiceImpl实现类

public interface AccountService {

    // 查询所有账户
    public List<Account> findAll();

    // 保存帐户信息
    public void saveAccount(Account account);

}

@Service("accountService")
public class AccountServiceImpl implements AccountService{

    @Autowired
    private AccountDao accountDao;

    @Override
    public List<Account> findAll() {
        System.out.println("Service查询所有账户...");
        return accountDao.findAll();
    }


    @Override
    public void saveAccount(Account account) {
        System.out.println("Service保存帐户...");
        accountDao.saveAccount(account);
    }
}

3.配置日志

log4j.rootCategory=info, CONSOLE, LOGFILE

log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\spring-mvc.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

4.执行测试

@Test
    public void run1(){
        // 加载配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring.xml");
        // 获取对象
        AccountService as = (AccountService) ac.getBean("accountService");
        // 调用方法
        as.findAll();
    }

四、添加Spring MVC框架

1.配置springmvc.xml

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

    <!--开启注解扫描，只扫描Controller注解-->
    <context:component-scan base-package="cn.ybzy">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <!--配置的视图解析器对象-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!--过滤静态资源-->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />
    <!-- 静态资源文件的处理放行 -->
	 <!-- <mvc:default-servlet-handler /> -->
	
    <!--开启SpringMVC注解的支持-->
    <mvc:annotation-driven/>
</beans>

2.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">


  <!--配置前端控制器-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--加载springmvc.xml配置文件-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <!--启动服务器，创建该servlet-->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!--解决中文乱码的过滤器-->
  <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  
</web-app>

3.注解配置Controller表现层

AccountController

@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("Controller查询所有账户...");
        // 调用service的方法
        List<Account> list = accountService.findAll();
        //使用model视图返回
        model.addAttribute("list",list);
        return "list";
    }
}

五、整合 Spring和SpringMVC

在web.xml中配置spring的监听器实现启动服务创建容器

<!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--设置配置文件的路径-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml</param-value>
  </context-param>

六、添加Mybatis框架

1.编写注解SQL

@Repository
public interface AccountDao {

    // 查询所有账户
    @Select("select * from account")
    public List<Account> findAll();

    // 保存帐户信息
    @Insert("insert into account (name,money) values (#{name},#{money})")
    public void saveAccount(Account account);

}

2.配置 SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
   <!-- <properties resource="jdbcConfig.properties"></properties>-->
    <environments default="mysql">
        <environment id="mysql">
            <transactionManager type="JDBC"></transactionManager>
            <dataSource type="pooled">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/ssm"/>
                <property name="username" value="root"/>
                <property name="password" value="123456"/>
            </dataSource>
        </environment>
    </environments>
    <mappers>
  	  <!--mapper映射器,扫描接口类-->
      <mapper class="cn.ybzy.dao.AccountDao"/>
    </mappers>
</configuration>

3.执行测试

public class TestMyBatis {

    @Test
    public void test1() throws Exception {
        // 加载配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        // 创建SqlSessionFactory对象
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        // 创建SqlSession对象
        SqlSession session = factory.openSession();
        // 获取到代理对象
        AccountDao dao = session.getMapper(AccountDao.class);
        // 查询所有数据
        List<Account> list = dao.findAll();
        for(Account account : list){
            System.out.println(account);
        }
        // 关闭资源
        session.close();
        in.close();
    }

    @Test
    public void test2() throws Exception {
        Account account = new Account();
        account.setName("大白");
        account.setMoney(123D);

        // 加载配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        // 创建SqlSessionFactory对象
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        // 创建SqlSession对象
        SqlSession session = factory.openSession();
        // 获取到代理对象
        AccountDao dao = session.getMapper(AccountDao.class);
        // 保存
        dao.saveAccount(account);
        // 提交事务
        session.commit();
        // 关闭资源
        session.close();
        in.close();
    }

}

七、整合Spring和MyBatis

整合Spring和MyBatis只需要把 mybatis 配置文件（SqlMapConfig.xml）中内容配置到 spring 配置文件中。

<!--Spring整合MyBatis框架-->

<!-- 加载配置文件 -->
<!-- <context:property-placeholder location="classpath:jdbcConfig.properties" />-->

    <!--配置连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql:///ssm"/>
        <property name="user" value="root"/>
        <property name="password" value="123456"/>
    </bean>

    <!--配置 MyBatis 的SqlSessionFactory工厂-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
    </bean>

   <!-- 配置扫描dao的包 -->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.ybzy.dao"/>
    </bean>

八、配置 spring 的事务

<!--配置Spring框架声明式事务管理-->
    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
        <tx:method name="save*" propagation="REQUIRED" read-only="false"/>
           <tx:method name="*" propagation="REQUIRED" read-only="false"/>
			<tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
        </tx:attributes>
    </tx:advice>

	
 
    <!--配置AOP-->
    <aop:config>
    <!-- 配置切入点表达式 -->
		<aop:pointcut expression="execution(* cn.ybzy.service.impl.*.*(..))" id="pt1"/>
		
   		 <!-- 建立通知和切入点表达式的关系 -->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pt1"/>
    </aop:config>

九、测试整合结果

1.执行方法测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations= {"classpath:spring.xml"})
public class TestSpringMabatis {
	@Autowired
	private AccountService accountService;
	
	@Test
	public void testFindAll() {
		List list = accountService.findAllAccount();
		System.out.println(list);
	}
	
	@Test
	public void testSave() {
		Account account = new Account();
		account.setName("Test");
		account.setMoney(123D);
		accountService.saveAccount(account);
	}
}

2.Controller表现层添加方法

@RequestMapping("/findAll")
public ModelAndView findAll() {
	List<Account> accounts = accountService.findAll();
	ModelAndView mv = new ModelAndView();
	mv.addObject("accounts", accounts);
	mv.setViewName("accountlist");
	return mv;
}

@RequestMapping("/saveAccount")
public String saveAccount(Account account) {
	accountService.saveAccount(account);
	return "redirect:findAll";
}

3.编写Jsp页面

index.jsp :保存页面

<body>
<a href="account/findAll">查询所有账户</a>
	<hr/>
	<form action="account/saveAccount" method="post">
	账户名称：<input type="text" name="name"/><br/>
	账户金额：<input type="text" name="money"><br/>
	<input type="submit" value=" 保存 "/>
	</form>
</body>

账户列表页面: accountlist.jsp

<body>
<table border="1" width="300px">
	<tr>
		<th>编号ID</th>
		<th>账户名称</th>
		<th>账户金额</th>
	</tr>
<c:forEach items="${accounts}" var="account" varStatus="as">
	<tr>
		<!--varStatus as.count输出行号，从1开始-->
		<td>${as.count}</td>
		<td>${account.name }</td>
		<td>${account.money }</td>
	</tr>
</c:forEach>
</table>
</body>
