(项目结构图参照文章末尾)

1、创建maven工程,在pom.xml文件中导入需要的jar包依赖:

2、整合SpringMVC:

(1)在web.xml文件中配置前端控制器:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="serviceMarket" version="2.5">
	
	<display-name>ssm-test</display-name>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
 
	<!-- 加载spring相关配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring/applicationContext*.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener> 
	
	<!-- 解决post乱码 -->
	<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>
	
	
	<!-- springmvc的前端控制器 -->
 	<servlet>
		<servlet-name>ssm-test</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 加载springmvc的配置文件(处理器映射器、处理器适配器等等) -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>ssm-test</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
 
</web-app>

(2)编写springmvc.xml文件:

在文件中配置与springmvc框架相关的配置,比如:springmvc.xml约束、处理器映射器、处理器适配器、视图解析器、Handler等配置。

<?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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	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-4.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
 
	<!-- 使用注解驱动:自动配置处理器映射器与处理器适配器 -->
	<mvc:annotation-driven />
 
	<!-- 注解方式:配置Handler,自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 -->
       <!-- 批量加载:组件扫描方式: -->
	<context:component-scan base-package="com.zwp.controller" />
 
 	<!-- 视图解析器:解析jsp页面,默认使用jstl标签,classpath下得有jstl的包 -->  
       <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
           <!-- 配置前后缀 -->
           <property name="prefix" value="/WEB-INF/jsp/"></property>
          <property name="suffix" value=".jsp"></property>
       </bean>
	
	<!-- 静态资源处理,不拦截静态资源,如css、js、imgs -->
	<mvc:resources location="/static/css/" mapping="/static/css/**"/>
	<mvc:resources location="/static/js/" mapping="/static/js/**"/>
	<mvc:resources location="/static/img/" mapping="/static/img/**"/>
 
	<!-- 文件上传相关配置 -->
	<bean id="multipartResolver"
	  class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
	  <property name="defaultEncoding" value="UTF-8"></property>
	  <property name="maxUploadSize" value="10240000"></property>
	</bean>
</beans>

(3)编写Handler:

//User类的Handler
//需要在类上面加@Controller注解,这样才能被自动扫描到
@Controller
@RequestMapping("/user")
public class UserController {
 
	private static Logger log=LoggerFactory.getLogger(UserController.class);
   
  @RequestMapping(value="/login",method=RequestMethod.GET) 
  public String login(HttpServletRequest request,Model model){ 
    String username = request.getParameter("username"); 
    String password = request.getParameter("password");
    System.out.println("username:"+username+";password:"+password);
    User user=null;
    if (username.equals("zwp") && password.equals("123456")) {
       user = new User(); 
       user.setAge(11);
       user.setId(1);
       user.setPassword("123456");
       user.setUsername("zwp");
       
       log.debug(user.toString());
    }
    
    model.addAttribute("user", user); 
    return "index"; 
  } 
}
//User实体类
public class User {
 
	private Integer id;
	private String username;
	private String password;
	private Integer age;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	
	@Override
	public String toString() {
		return "User [id=" + id + ", username=" + username + ", password=" + password + ", age=" + age + "]";
	}
}

(4)配置日志文件:

在项目根目录下面创建log4j.properties日志文件,下面是日志文件的基本配置,可以满足大多数项目的需求。

log4j.rootLogger=INFO,Console,File 
#定义日志输出目的地为控制台 
log4j.appender.Console=org.apache.log4j.ConsoleAppender 
log4j.appender.Console.Target=System.out 
#可以灵活地指定日志输出格式,下面一行是指定具体的格式 
log4j.appender.Console.layout = org.apache.log4j.PatternLayout 
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n 
 
#文件大小到达指定尺寸的时候产生一个新的文件 
log4j.appender.File = org.apache.log4j.RollingFileAppender 
#指定输出目录 
log4j.appender.File.File = logs/ssm.log 
#定义文件最大大小 
log4j.appender.File.MaxFileSize = 10MB 
# 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志 
log4j.appender.File.Threshold = ALL 
log4j.appender.File.layout = org.apache.log4j.PatternLayout 
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

(5)启动项目,进行测试:

访问地址:http://localhost:8080/ssm/user/login?username=zwp&password=123456,如果出现下面页面则代表映射成功。

至此,SpringMVC的配置就已经成功。

3、Spring和Mybatis框架的整合:

整合思路:由Spring通过单例方式管理SqlSessionFactory;spring和mybatis整合生成代理对象,使用SqlSessionFactory创建SqlSession,持久层的mapper都需要有spring进行管理。

(1)配置dao层,即配置sqlSessionFactory:(我的配置在applicationContext-dao.xml文件中)

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	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-4.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
 
	<!-- 1.加载配置文件 -->
	<!-- 第一种加载多个.properties文件的方法 -->
	<context:property-placeholder location="classpath:resource/*.properties"/>
	
	<!-- 2.配置数据库连接池 -->
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
		destroy-method="close">
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="maxActive" value="10" />
		<property name="minIdle" value="5" />
	</bean>
	
	<!-- 3.让spring创建并管理sqlsessionfactory,使用mybatis和spring整合包中的 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 配置数据源,数据库连接池 -->
		<property name="dataSource" ref="dataSource" />
		<!-- 加载mybatis的全局配置文件 -->
		<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
	</bean>
	
	<!-- 4.mapper批量扫描:从mapper包中扫描出mapper,自动创建代理对象并且在spring容器中注册
	 	需要遵循规范:mapper接口类名和mapper.xml映射文件名称一致,且在同一目录下,
	 	自动扫描出来的mapper的bean的id为类名(首字母小写)-->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.zwp.mapper" />
	</bean>
</beans>

创建并编写SqlMapConfig.xml文件:

<?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>
	<plugins>
		<!-- com.github.pagehelper为PageHelper类所在包名 -->
		<plugin interceptor="com.github.pagehelper.PageHelper">
			<!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库 -->
			<property name="dialect" value="mysql" />
		</plugin>
	</plugins>
</configuration>

(2)配置service层:(我的配置在applicationContext-service.xml文件中)

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	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-4.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
 
	<!-- 自动扫描service层的接口与实现类 -->
	<context:component-scan base-package="com.zwp.service" />
</beans>

(3)配置事务:(我的配置在applicationContext-trans.xml文件中)

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	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-4.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
 
	<!-- 事务管理器 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<!-- 数据源 -->
		<property name="dataSource" ref="dataSource" />
	</bean>
	
	<!-- 通知 -->
	<tx:advice id="txAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<!-- 传播行为 -->
			<tx:method name="add*" propagation="REQUIRED" />
			<tx:method name="create*" propagation="REQUIRED" />
			<tx:method name="insert*" propagation="REQUIRED" />
			<tx:method name="save*" propagation="REQUIRED" />
			<tx:method name="update*" propagation="REQUIRED" />
			<tx:method name="delete*" propagation="REQUIRED" />
			<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
		</tx:attributes>
	</tx:advice>
	<!-- 切面 -->
	<aop:config>
		<aop:advisor advice-ref="txAdvice"
			pointcut="execution(* com.zwp.service.*.*(..))" />
	</aop:config>
</beans>

至此,Spring和Mybatis框架的整合就完成了。

4、测试:

(1)创建测试用表:

(2)利用MyBatis-Generator自动创建实体类、Mybatis映射文件以及Dao接口。

(3)建立Service和实现类:

//UserService接口类:
@Service
public interface UserService {
	
	public User getUserById(int userId);
	
}
//UserService的实现类
@Service
public class UserServiceImpl implements UserService {
	
	//注入UserMapper接口
	@Autowired
	private UserMapper userMapper;
 
	@Override
	public User getUserById(int userId) {
		User user = userMapper.selectByPrimaryKey(userId);
		return user;
	}
}

(3)建立UserController类:

//User类的Handler
//需要在类上面加@Controller注解,这样才能被自动扫描到
@Controller
@RequestMapping("/user")
public class UserController {
	
	@Autowired
	private UserService userService;
 
	private static Logger log=LoggerFactory.getLogger(UserController.class);
   
	@RequestMapping(value="/getUserById/{userId}",method=RequestMethod.GET)
	public @ResponseBody User getUserById(@PathVariable Integer userId){
		
		return userService.getUserById(userId);
	}
	
  @RequestMapping(value="/login",method=RequestMethod.GET) 
  public String login(HttpServletRequest request,Model model){ 
    String username = request.getParameter("username"); 
    String password = request.getParameter("password");
    System.out.println("username:"+username+";password:"+password);
    User user=null;
    if (username.equals("zwp") && password.equals("123456")) {
       user = new User(); 
       user.setAge(11);
       user.setId(1);
       user.setPassword("123456");
       user.setUsername("zwp");
       
       log.debug(user.toString());
    }
    
    model.addAttribute("user", user); 
    return "index"; 
  } 
}

(4)部署项目,输入地址:http://localhost:8080/ssm/user/getUserById/2,出现下面响应结果,则表示整合成功了。

至此,Maven+Spring+SpringMVC+Mybatis的整合就完成了。
