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>
