**[个人博客传送门][Link 1]**

SSM（Spring+SpringMVC+Mybatis），目前较为主流的企业级架构方案。标准的MVC设计模式，将整个系统划分为显示层、Controller层、Service层、Dao层四层，使用SpringMVC负责请求的转发和视图管理，Spring实现业务对象管理, MyBatis作为数据对象持久化引擎，以上说明来自百度。

这个框架相信对于大家来说都不会太陌生，用的都比较多，本猿作作为一名萌新，入职以来虽然一直都在使用SSM框架但是对于该框架的搭建不是很了解，借此次项目的机会搭建了一次并且成功，很是喜悦，因此记录下来方便以后查看，也为像本猿一样的新人提供一点帮助。

一.环境的准备搭建

首先你需要创建一个maven项目，本猿用的是StS大家可以根据自己的喜好选择。

1.先创建一个maven项目

![Center][]

2.选择该项

![Center 1][]

3.接下来输入你的项目的名称和包的目录结构

![Center 2][]

4.然后项目就创建完成了，接下来你需要创建src/main/resources、src/main/java、src/test/resources、src/test/java，创建完之后项目的结构如图所示。

![Center 3][]

5.然后分别修改输出的路径。

![Center 4][]

到此，项目的创建工作基本上就完成了，接下里就需要进行框架的整合了，框架的整合我分为两部分来做的，第一部分先整合Spring和Mybatis的框架

，接下来是整合springMvc的。

二、Spring和Mybatis

我先一次给出我导入的所有的jar包，上面都有很详细的注释的，应该可以看懂的。

      <build>

      </build>
    </project>

1.先配置创建一个xml来放spring和mybatis的配置文件，主要存放的是自动扫描、自动注入和数据库的配置等。

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: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">  
          
        <context:component-scan base-package="com.ssm" />  
          
        <bean id="propertyConfigurer"  
            class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
            <property name="location" value="classpath:jdbc.properties" />  
        </bean>  
      
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init"
            destroy-method="close">  
            <property name="driverClassName" value="${driver}" />  
            <property name="url" value="${url}" />  
            <property name="username" value="${username}" />  
            <property name="password" value="${password}" />  
              
            <property name="initialSize" value="${initialSize}"></property>  
              
            <property name="maxActive" value="${maxActive}"></property>  
              
            <property name="maxIdle" value="${maxIdle}"></property>  
              
            <property name="minIdle" value="${minIdle}"></property>  
              
            <property name="maxWait" value="${maxWait}"></property>  
        </bean>  
        
      
          
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
            <property name="dataSource" ref="dataSource" />  
              
            <property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>  
        </bean>  
      
          
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
            <property name="basePackage" value="com.ssm.dao" />  
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>  
        </bean>  
      
          
        <bean id="transactionManager"  
            class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
            <property name="dataSource" ref="dataSource" />  
        </bean>  
      
    </beans>

2.配置log日志(此配置方法来自网络)

log4j.properties

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

3.配置数据库的连接

jdbc.properties

driver=com.mysql.jdbc.Driver 
    url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8  
    username=root  
    password=  
    #定义初始连接数 
    initialSize=0  
    #定义最大连接数  
    maxActive=20  
    #定义最大空闲  
    maxIdle=20  
    #定义最小空闲  
    minIdle=1  
    #定义最长等待时间  
    maxWait=60000

到此Spring和mybatis的配置就完成了，接下来就剩下整合SpringMvc了，我先吧所有的配置完成之后再上我的测试代码吧。

三.Spring MVC 的配置

主要是配置自动扫描，和注解的启动和拦截器等。

1.先新建SpringMVC的配置文件。

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">  
                            
          
        <context:component-scan base-package="com.ssm.controller" />  
        
          
        <bean id="mappingJacksonHttpMessageConverter"  
            class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">  
            <property name="supportedMediaTypes">  
                <list>  
                    <value>text/html;charset=UTF-8</value>  
                </list>  
            </property>  
        </bean>  
          
        <bean  
            class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">  
            <property name="messageConverters">  
                <list>  
                    <ref bean="mappingJacksonHttpMessageConverter" />   
                </list>  
            </property>  
        </bean>  
        
        
         <mvc:annotation-driven >
            <mvc:message-converters>
                <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                	<property name="supportedMediaTypes"> 
    	                <list>  
    	                    <value>application/json;charset=UTF-8</value>  
    	                </list>  
    	            </property>
    	            <property name="features">
    	            	<list>
    	            	<value>DisableCircularReferenceDetect </value>
    	            	<value>WriteMapNullValue</value>
    	            	<value>WriteNullListAsEmpty</value>
    	            	<value>WriteNullStringAsEmpty</value>
    	            	</list>
    	            </property>  
                </bean>
            </mvc:message-converters>
        </mvc:annotation-driven>
        
          
        <bean id="multipartResolver"    
            class="org.springframework.web.multipart.commons.CommonsMultipartResolver">    
              
            <property name="defaultEncoding" value="utf-8" />    
              
            <property name="maxUploadSize" value="10485760000" />    
              
            <property name="maxInMemorySize" value="40960" />    
        </bean>   
      
    </beans>

四 .接下来是在web.xml中将SpringMVC和前面的东西进行整合。

web.xml

<?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>

            <param-value>classpath:spring-mybatis.xml</param-value>  
        </context-param>  
        
       
         
        <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>

            <url-pattern>/*</url-pattern>  
        </filter-mapping>  
          
        <listener>
