# SSM整合流程 #

#### 一、首先是环境搭建： ####

1.引入相关依赖：

<dependency>
    	    <groupId>javax.servlet</groupId>
    	    <artifactId>servlet-api</artifactId>
    	    <version>2.5</version>
    	    <scope>provided</scope>
    	</dependency>
    	
    	<dependency>
    	    <groupId>org.springframework</groupId>
    	    <artifactId>spring-core</artifactId>

    	</dependency>
    	<dependency>

    	</dependency>
    	<dependency>

    	    <artifactId>spring-beans</artifactId>

    	</dependency>
    	<dependency>
    	    <groupId>org.springframework</groupId>
    	    <artifactId>spring-expression</artifactId>
    	    <version>4.3.2.RELEASE</version>
    	</dependency>
    	<dependency>
    	    <groupId>org.springframework</groupId>
    	    <artifactId>spring-aop</artifactId>
    	    <version>4.3.2.RELEASE</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>org.mybatis</groupId>
    	    <artifactId>mybatis</artifactId>
    	    <version>3.2.8</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>org.mybatis</groupId>
    	    <artifactId>mybatis-spring</artifactId>
    	    <version>1.3.2</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>org.apache.struts</groupId>
    	    <artifactId>struts2-core</artifactId>
    	    <version>2.3.16</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>org.apache.struts</groupId>
    	    <artifactId>struts2-spring-plugin</artifactId>
    	    <version>2.3.16</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>mysql</groupId>
    	    <artifactId>mysql-connector-java</artifactId>
    	    <version>5.1.38</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>commons-dbcp</groupId>
    	    <artifactId>commons-dbcp</artifactId>
    	    <version>1.4</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>com.alibaba</groupId>
    	    <artifactId>fastjson</artifactId>
    	    <version>1.2.47</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>log4j</groupId>
    	    <artifactId>log4j</artifactId>
    	    <version>1.2.15</version>
    	</dependency>
    	
    	<dependency>
    	    <groupId>jstl</groupId>
    	    <artifactId>jstl</artifactId>
    	    <version>1.2</version>
    	</dependency>
    	<dependency>
    	    <groupId>javax.servlet.jsp</groupId>
    	    <artifactId>jsp-api</artifactId>
    	    <version>2.2</version>
    	</dependency>
    	<dependency>
    	    <groupId>junit</groupId>
    	    <artifactId>junit</artifactId>
    	    <version>4.12</version>
    	    <scope>test</scope>
    	</dependency>

2、初始化配置( web.xml )  
主要有两个：**struts2的核心过滤器**和**Spring工厂监听器**。

<context-param>
      	<param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
      </context-param>
      
      
      <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
      </filter>
      <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern> </filter-mapping>  <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

## 2、开发步骤 ##

1、建表

2、写实体类

3、写DAO接口

4、Mapper文件实现DAO接口

5、在Spring配置文件总配置mybatis的相关内容

<context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>
            
           	jdbc.properties小的配置文件内容如下
            driver=com.mysql.jdbc.Driver
            url=jdbc:mysql://localhost:3306/ssm
            name=root
            password=root
            
        
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="${driver}"></property>
            <property name="url" value="${url}"></property>
            <property name="username" value="${name}"></property>
            <property name="password" value="${password}"></property>
        </bean>  
        
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"></property>
            
            <property name="typeAliasesPackage">
                <value>com.baizhi.entity</value>
            </property>
            
            <property name="mapperLocations">
                <list>
                    <value>classpath:com/baizhi/dao/*Mapper.xml</value> </list> </property> </bean>  <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage"> <value>com.baizhi.dao</value>//dao所在的包名 </property> </bean>

6、定义Service接口

将dao实现类作为Service层的属性 做set注入

7、实现Service接口

在applicationContext.xml文件中配置相关信息

8、配置额外功能的事务

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"></property>
        </bean>
    
        
        <tx:advice id="dstm" transaction-manager="transactionManager">
            <tx:attributes>
                <tx:method name="modify*"/>//增删改的配置
                <tx:method name="*" propagation="SUPPORTS" read-only="true"></tx:method>//查询的配置
            </tx:attributes>
        </tx:advice>
    
        <aop:config>
            
            <aop:pointcut id="pc" expression="execution(* com.baizhi.service..*.*(..))"></aop:pointcut>
            
            <aop:advisor pointcut-ref="pc" advice-ref="dstm"></aop:advisor>
        </aop:config>

9、开发Adtion

将Service作为属性 做set注入

10、配置Action的相关信息

11、配置Struts的相关信息

在struts.xml配置文件中配置相关信息

12、在JSP页面中调用相对应的Action类
