ssm框架搭建二----环境搭建

这是整体的目录结构：

首先导入需要的包

接下来修改web.xml文件：

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://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><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mybatis.xml</param-value></context-param><!-- 配置Log4j --><!-- <context-param> <param-name>webAppRootKey</param-name> <param-value>spring_springmvc_jpa.root</param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <listener> <listener-class> org.springframework.web.util.Log4jConfigListener </listener-class> </listener> --><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><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- Spring 刷新Introspector防止内存泄露 --><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><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><url-pattern>/</url-pattern></servlet-mapping><welcome-file-list><welcome-file>/index.jsp</welcome-file></welcome-file-list><session-config><session-timeout>15</session-timeout></session-config></web-app>

然后编写相关xml文件

1：spring与mybatis：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.wang.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><bean id="paginationInterceptor" class="com.wang.ssm.dialet.OffsetLimitInterceptor"></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" /><property name="plugins"><ref bean="paginationInterceptor" /></property><!-- 自动扫描mapping.xml文件 --><property name="mapperLocations" value="classpath:com/wang/ssm/mapping/*.xml"></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><!-- 定义方言管理器bean,会被自定义分页拦截器OffsetLimitInterceptor类引用，故,这里需要定义 --><bean id="mybatisDefaultDialectManager" class="com.wang.ssm.dialet.DefaultDialectManager"><property name="dialects"><map><entry><key><value>mysql</value></key><bean class="com.wang.ssm.dialet.MySQLDialect" /></entry></map></property></bean></beans>

2：配置springmvc相关xml : 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.wang.ssm.controller/" /><!-- 标注次文件夹下的所有静态文件都能被外界访问 --><mvc:resources mapping="/resources/**" location="/resources/" /> <mvc:annotation-driven><span style="white-space:pre"></span><!-- 消息转换器,解决responseBody返回中外乱码问题 --><span style="white-space:pre"></span><mvc:message-converters register-defaults="true"><span style="white-space:pre"></span><bean class="org.springframework.http.converter.StringHttpMessageConverter"><span style="white-space:pre"></span><property name="supportedMediaTypes" value="text/html;charset=UTF-8" /><span style="white-space:pre"></span></bean><span style="white-space:pre"></span></mvc:message-converters><span style="white-space:pre"></span></mvc:annotation-driven><!--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 --><beanclass="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="suffix" value=".jsp" /></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> </beans>

最后编写jdbc.properties

driver=com.mysql.jdbc.Driverurl=jdbc:mysql://localhost:3306/weixinusername=rootpassword=rootinitialSize=0maxActive=20maxIdle=20minIdle=1maxWait=60000

注意：mybatis mapper接口类存放路径为：src/com.wang.ssm.dao中；mapper.xml文件存放在resource/com.wang.ssm.mapper中

至此ssm环境已搭建完成

还有一些对分页的封装，基础dao接口的封装就不一一贴出来了，后面会附上项目源代码，需要的可以下载来看看
