先看效果： 

之后会有源代码，最好下载并对着代码观看

使用maven管理项目，需要注意修改编译输出目录。否则后期运行可能找不到类。 

1.先建立必要的包。 
如图所示：

2.根据数据库建立必要的表。 
3.在pop.xml中引入必要的配置；

然后执行 maven install。成功后配置SSM。 
建立 spring-mybatis.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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!-- 自动扫描 --> <context:component-scan base-package="com.lava" /> <!-- 引入配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${driverClassName}" /> <property name="url" value="${url}" /> <property name="username" value="${username}" /> <property name="password" value="${password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="${initialSize}"></property> <!-- 连接池最大数量 --> <property name="maxActive" value="${maxActive}"></property> <!-- 连接池最大空闲 --> <property name="maxIdle" value="${maxIdle}"></property> <!-- 连接池最小空闲 --> <property name="minIdle" value="${minIdle}"></property> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="${maxWait}"></property> </bean> <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:com/lava/lavafaq/mapping/*.xml"></property> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.lava.lavafaq.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> </beans>

建立 spring-mvc.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: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-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 --> <context:component-scan base-package="com.lava.lavafaq.controller" /> <!--避免IE执行AJAX时，返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 --> </list> </property> </bean> <!-- 定义跳转的文件的前后缀 ，视图模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 --> <!-- <property name="prefix" value="/WEB-INF/jsp/" /> --> <property name="prefix" value="/pages/" /> <property name="suffix" value=".jsp" /> <property name="order" value="1" /> </bean> <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> <!-- 扩充了注解驱动，可以将请求参数绑定到控制器参数 --> <mvc:annotation-driven/> <!-- 启用基于Spring的注解 --> <context:annotation-config/> <!-- 静态资源处理 --> <mvc:resources mapping="/script/**" location="/script/" /> <mvc:resources mapping="/app/**" location="/app/" /> <mvc:resources mapping="/css/**" location="/css/" /> <mvc:resources mapping="/images/**" location="/images/" /> <!-- 国际化配置 --> <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> <property name="basename"> <value>message</value> </property> <property name="defaultEncoding"> <value>UTF-8</value> </property> </bean> <!-- 日期全局转换配置 --> <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"> <property name="converters"> <list> <bean class="com.lava.lavafaq.springmvc.DateConverter" /> </list> </property> </bean> </beans> 

然后在 web.xml中添加：

<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- Spring和mybatis的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring MVC servlet --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <!-- 配置SESSION超时，单位是分钟 --> <session-config> <session-timeout>15</session-timeout> </session-config> </web-app>

然后建立 jdbc.properties和log4J.properties

driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/faq username=root password=123456 initialSize=10 maxActive=300 maxIdle=20 minIdle=1 maxWait=60000 log4j.rootLogger=DEBUG,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

至此配置完成。配置是SSM中至关重要的部分，只要配置成功，接下来很容易 
然后写入SSM逻辑代码（看源码）。 
然后建立测试类，测试Spring与mybatis

@RunWith(SpringJUnit4ClassRunner.class)     //表示继承了SpringJUnit4ClassRunner类  
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"}) 

public class TestMyBatis { private static Logger logger = Logger.getLogger(TestMyBatis.class); //private ApplicationContext ac = null; @Resource private IPersonService personService = null; /* @Before public void before() { ac = new ClassPathXmlApplicationContext("applicationContext.xml"); userService = (IUserService) ac.getBean("userService"); } */ @Test public void test1() { Person person = new Person(); person.setMail("114336"); person.setPassword("114336"); logger.info(personService.loginPerson(person)); logger.info("ws"); } 

如果控制台有打印personService.loginPerson(person)返回值，即成功（之后会有源代码，对着代码观看）

然后测试spring-mvc 
浏览器地址栏输入： 
输入地址：localhost:8080/项目名称/user/login 跳转至登录界面即成功。

下面走一遍代码实现逻辑流程 
输入完毕，点击注册按钮。执行Ajax

login.js

$.ajax({
            type: reMethod,
            url: "/ssm/login/person",
            data: sendData,
            dataType: "json",
            success: function(result) {             
                if (result.success) { $('#user').focus().css({ border: "1px solid green", boxShadow: "0 0 2px green" }); $("#userCue").html("<font color='green'><b>"+result.text+"</b></font>"); alert(result.text);  return false; } else { $('#user').css({ border: "1px solid #D7D7D7", boxShadow: "none" }); $("#userCue").html("<font color='red'><b>"+result.text+"</b></font>"); alert(result.text); } } });

spring mvc 拦截 url: “/ssm/login/person”,

@Controller  
@RequestMapping("/login")  
public class LoginController { ......... @RequestMapping("/person") @ResponseBody private Object register(Person person){ logger.debug("ws--register-------"); person.setState(0); return ResponseUtils.sendSuccess(this.personService.registerPerson(person)); }

数据合法则发邮件给用户，等待激活。

点击登录按钮，通过表单提交

<div class="login_form">
                <form action="<%=basePath%>login/index" name="loginform" accept-charset="utf-8" id="login_form" class="loginForm" method="post"><input type="hidden" name="did" value="0"/> <input type="hidden" name="to" value="log"/> <div class="loginHint" id="loginHint">${param.result}</div> <div class="uinArea" id="uinArea"> <label class="input-tips" for="u">帐号：</label> <div class="inputOuter" id="uArea"> <input type="text" id="u" name="mail" class="inputstyle"/> </div> </div> <div class="pwdArea" id="pwdArea"> <label class="input-tips" for="p">密码：</label> <div class="inputOuter" id="pArea"> <input type="password" id="p" name="password" class="inputstyle"/> </div> </div> <div style="padding-left:50px;margin-top:20px;"><input type="submit" value="登 录" style="width:150px;" class="button_blue"/></div> </form> </div>

String mvc拦截登录请求

    @RequestMapping("/index")   
    private String login(Person person,ModelMap modelMap){  
         logger.debug("ws-----activatemail----person.getPassword();="+person.getPassword()+" email="+person.getMail()); String result = this.personService.loginPerson(person); if(result.equals("登陆成功")){ return "index"; } modelMap.addAttribute("result",result); logger.debug("ws-----login----result="+result); return "redirect:/user/login"; }
