1、pom.xml
首先，pom.xml文件，里面包含各种maven的依赖，代码如下：

pom.xml
2、web.xml
完成第一步后，系统通常会自动下载相应的依赖包，然后，编写web.xml中的内容，代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
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_2_5.xsd"> <display-name>Archetype Created Web Application</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value>
</context-param>
<!-- 字符集 过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener> <servlet>
<servlet-name>mvc-dispather</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 改变默认的上下文配置 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:mvc-dispather-servlet.xml,classpath:spring-mybatis.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup> </servlet> <servlet-mapping>
<servlet-name>mvc-dispather</servlet-name>
<!-- 拦截所有请求 -->
<url-pattern>/</url-pattern>
</servlet-mapping> <!-- 配置session超时时间为2小时 -->
<session-config>
<session-timeout>120</session-timeout>
</session-config>
</web-app>
web.xml
在web.xml文件中，红线圈出的几个文件具体的配置将在后面给出。
3、resources资源目录下各文件的配置
（1）spring.xml
也是在web.xml文件中所涉及到的配置文件，下面给出相应代码
<?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-4.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!--引入配置属性文件 -->
<context:property-placeholder ignore-unresolvable="true" location="classpath:/config.properties" />
<context:property-placeholder ignore-unresolvable="true" location="classpath:/mysite.properties" /> <!--自动扫描含有@Service将其注入为bean -->
<context:component-scan base-package="com.suixue.*.service" /> </beans>
spring.xml
此处的两种配置文件，将在下面详细给出。
--》config.properties
#mysql version database druid setting
validationQuery=SELECT 1
jdbc.jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/movie_management?useUnicode=true&characterEncoding=utf-8
jdbc.username=suixue
jdbc.password=123456
注意更换此文件中的数据库名称以及username和password
--》mysite.properties
adminPath=system/a/
只有此一行代码，此处为浏览器访问页面时url的前缀，比如localhost:8080/system/a/login
（2）spring-mybatis.xml
同时是web.xml文件中涉及到的配置文件，代码如下
<?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:tx="http://www.springframework.org/schema/tx"

xsi:schemaLocation="

"> <!-- 配置数据源 使用的是Druid数据源 -->
<bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource"

<property name="validationQuery" value="${validationQuery}" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
<property name="testWhileIdle" value="true" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="25200000" />

<!-- 监控数据库 -->
<property name="filters" value="mergeStat" /> </bean> <!-- myBatis文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->
<property name="mapperLocations" value="classpath:com/suixue/mapper/*.xml" />
<property name="plugins"> <array>
<bean class="com.github.pagehelper.PageHelper">
<property name="properties">

</value>
</property>
</bean>

</bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />

<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
<tx:method name="select*" propagation="SUPPORTS" read-only="true" /> </tx:attributes>
</tx:advice>
<!-- Spring aop事务管理 -->
<aop:config>
<aop:pointcut id="transactionPointcut" expression="execution(* com..*service.*(..))" />
<aop:advisor pointcut-ref="transactionPointcut"
advice-ref="transactionAdvice" />
</aop:config></beans>
spring-mybatis
应注意此处应改成自己的数据库名称以及登录名和密码
此处路径应改成自己相应的mapper路径，匹配其下面所有的xml文件，这里所说的xml文件中，包含的是sql语句，类似于下面的内容
另外，spring-mybatis.xml文件中下面红色的部分应对应自己项目中的dao层接口，以使得上面刚刚提到的mapper中的xml(包含sql语句)与dao层下的文件相映射起来。
此例子中com.suixue.**.dao包下面包含java文件，该java文件不是一个类class,而是一个接口。
下面给出我一个项目中的对应关系，方便理解。
另外，还需要注意的是
此处限制了涉及数据库增删改查操作的时候方法名的命名限制。
此处应对应好自己项目中的service方法，有固定语法，不了解的地方请自己查阅相关资料。
这是我的service文件的结构信息。
（3）mvc-dispather-servlet.xml
同样是在web.xml中涉及的配置文件，代码如下
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 激活标注 --> <context:annotation-config></context:annotation-config> <!-- DispatherContext上下文，只搜索标注了@Controller的类 -->
<context:component-scan base-package="com.suixue.*">
</context:component-scan>
<mvc:annotation-driven />
<!-- 启用基于mvc的HandlerMapping -->
<mvc:default-servlet-handler /> <mvc:interceptors>
<mvc:interceptor>
<!-- 所有文件夹及其子文件夹 -->
<mvc:mapping path="/system/*" />
<bean id="loginInterceptor" class=" com.suixue.system.common.LoginInterceptor"></bean>
</mvc:interceptor> </mvc:interceptors>
<!-- 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.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean> <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<!-- json转换器 -->
<ref bean="mappingJacksonHttpMessageConverter" />
</list>
</property>
</bean>
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView"></property>
<property name="prefix" value="/WEB-INF/jsps/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
mvc-dispather-servlet.xml
注意红色区域部分，做出相应更改，其中最后的bean配置中的class,改成自己对应的bean即可，下面给出我的LoginInterceptor.java文件的具体代码
package com.suixue.system.common;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;import com.suixue.system.user.entity.User;public class LoginInterceptor extends HandlerInterceptorAdapter{ private static final String[] LOGIN_URL = {"/login.form","login"}; @Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception { request.setCharacterEncoding("UTF-8");
String url = request.getRequestURI();
boolean flag = false; for(String s : LOGIN_URL){
if(url.contains(s)){
flag = true;
break;
}
} if(!flag){
User user = (User) request.getSession().getAttribute("user");
if(user == null){
String context = request.getContextPath();
response.sendRedirect(context + "/a/login");
return false;
}
}
return true;
}}
LoginInterceptor
此处设置前缀和后缀，根据需要可以自己更改。
当当当，至此，所有的基本配置到底就结束啦，若是有不足的地方，欢迎大家多多指正。
