## SSM框架搭建+Maven详细讲解（一） ##

**SSM （SSM 框架集）**

SSM（Spring+SpringMVC+MyBatis）框架集由Spring、SpringMVC、MyBatis三个开源框架整合而成，常作为数据源较简单的web项目的框架。

其中spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。

SpringMVC分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。

MyBatis是一个支持普通SQL查询，存储过程和高级映射的优秀持久层框架。

Maven的存在让ssm框架简单了一个量级不需要手动导入jar包。没有安装maven的可参考[maven安装及环境搭建][maven]

**下面就直接进入正题吧！！！！**

1、新建一个maven项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NtMTYxMTE_size_16_color_FFFFFF_t_70][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NtMTYxMTE_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NtMTYxMTE_size_16_color_FFFFFF_t_70 3][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NtMTYxMTE_size_16_color_FFFFFF_t_70 4][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NtMTYxMTE_size_16_color_FFFFFF_t_70 5][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NtMTYxMTE_size_16_color_FFFFFF_t_70 6][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NtMTYxMTE_size_16_color_FFFFFF_t_70 7][]

2、在pom.xml文件下引入需要的jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

        			</configuration>
        	</plugin>
        </plugins>
      </build>
    </project>

3、在src/main/resources文件下新建jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8
    jdbc.username=root
    jdbc.password=*******

4、在src/main/resources文件下新建mybatis-config.xml

<?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>
    	
    	<settings>
    		
    		<setting name="useGeneratedKeys" value="true" />
    
    		
    		<setting name="useColumnLabel" value="true" />
    
    		
    		<setting name="mapUnderscoreToCamelCase" value="true" />
    		
    	</settings>
    </configuration>

5、在src/main/resources/spring下新建spring-dao.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:context="http://www.springframework.org/schema/context"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
    	
    	
    	<context:property-placeholder location="classpath:jdbc.properties"/>
    	
    	
    	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    		
    		<property name="driverClass" value="${jdbc.driver}" />
    		<property name="jdbcUrl" value="${jdbc.url}" />
    		<property name="user" value="${jdbc.username}" />
    		<property name="password" value="${jdbc.password}" />
    
    		
    		<property name="maxPoolSize" value="30" />
    		<property name="minPoolSize" value="10" />
    		
    		<property name="autoCommitOnClose" value="false" />
    		
    		<property name="checkoutTimeout" value="10000" />
    		
    		<property name="acquireRetryAttempts" value="3" />
    	</bean>
    
    	
    	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    		
    		<property name="dataSource" ref="dataSource" />
    		
    		<property name="configLocation" value="classpath:mybatis-config.xml" />
    		
    		<property name="typeAliasesPackage" value="com.lzw.entity" />
    		
    		<property name="mapperLocations" value="classpath:mapper/*.xml" />
    	</bean>
    
    	
    	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    		
    		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    		
    		<property name="basePackage" value="com.lzw.dao" />
    	</bean>
    </beans>

6、在src/main/resources/spring下新建spring-service.xml

7、在src/main/resources/spring下新建spring-web.xml

8、修改web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" metadata-complete="true" version="3.1">
      <display-name>Archetype Created Web Application</display-name>
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>index.html</welcome-file>
      </welcome-file-list>
       <servlet>
      	<servlet-name>spring-dispatcher</servlet-name>
      	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      	<init-param>
      		<param-name>contextConfigLocation</param-name>
      		<param-value>classpath:spring/spring-*.xml</param-value>
      	</init-param>
      </servlet>
      <servlet-mapping>
      	<servlet-name>spring-dispatcher</servlet-name>
      	
      	<url-pattern>/</url-pattern>
      </servlet-mapping>
    </web-app>
