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。
