项目搭建（二）

项目的配置文件

1、jdbc.properties

#jdbc驱动类
driver=com.microsoft.sqlserver.jdbc.SQLServerDriver

#服务器url
url=jdbc:sqlserver://192.168.8.9;DatabaseName=ABC
#服务器用户名
username=sa
#服务器密码
password=1A2s3d4f5g

<!-- 初始化连接大小 -->
initialSize=0  
<!-- 连接池最大数量 --> 
maxActive=20  
<!-- 连接池最大空闲 -->
maxIdle=20  
<!-- 连接池最小空闲 -->
minIdle=1  
<!-- 获取连接最大等待时间 -->
maxWait=60000

2、整合spring和Mybatis的配置文件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">
    <!-- 自动扫描 -->
    <context:component-scan base-package="com.lph.ssm" />
    <!-- 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="${driver}" />
        <property name="url" value="${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/lph/ssm/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.lph.ssm.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>

3、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">  
  

    <!-- 配置springMVC -->
    <!-- 1.开启springMVC注解模式 -->
    <!--DispatcherServlet启用基于annotation的HandlerMapping -->
    <!-- a.自动注册DefaultAnnotationHandlerMapping,AnnotationMethodHandlerAdapter
         b.默认提供一系列的功能:数据绑定，数字和日期的format@NumberFormat,@DateTimeFormat
         c:xml,json的默认读写支持 
     -->
    <mvc:annotation-driven />
    
    
    
    <!--2.静态资源默认servlet配置-->
    <!--1).加入对静态资源处理：js,gif,png
        2).允许使用 "/" 做整体映射
    -->
    <mvc:default-servlet-handler/>
    
       <!-- 3.配置jsp的显示  ViewResolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/jsp/"/>
        <property name="suffix" value=".jsp"/>
   </bean>
 
    <!-- 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.lph.ssm.controller"/>
     
</beans>

4、日志log4j文件

#\u914D\u7F6E\u6839Logger
log4j.rootLogger=DEBUG,INFO,Console,File
#\u914D\u7F6E\u65E5\u5FD7\u4FE1\u606F\u8F93\u51FA\u76EE\u7684\u5730Appender

5、web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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/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/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>  
</web-app>

最后，把 java 包创建好，输入项目路径就可以访问到 index.jsp 看到 HelloWorld 了。
