1、pom.xml
首先，pom.xml文件，里面包含各種maven的依賴，代碼如下：
<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"> <modelVersion>4.0.0</modelVersion> <groupId>com.suixue.test</groupId> <artifactId>maven-demo-web</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>maven-demo-web Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring.version>4.1.4.RELEASE</spring.version> <jackson.version>2.5.0</jackson.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <!-- mybatis 包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> </dependency> <!--mybatis spring 插件 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- mysql連接 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.34</version> </dependency> <!-- 數據源 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.12</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.4</version> </dependency> <!-- log4j --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- servlet --> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>3.0-alpha-1</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- json --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jackson.version}</version> </dependency> <!-- 文件上傳 --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.2.2</version> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>4.0.1</version> </dependency> </dependencies> <build> <finalName>system</finalName> </build> <repositories> <repository> <id>sonatype-nexus-snapshots</id> <name>Sonatype Nexus Snapshots</name> <url>http://oss.sonatype.org/content/repositories/snapshots</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> </project>
2、web.xml
完成第一步后，系統通常會自動下載相應的依賴包，然后，編寫web.xml中的內容，代碼如下：
<?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 過濾器 --> <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> <listener> <listener-class> org.springframework.web.context.ContextCleanupListener</listener-class> </listener> <servlet> <servlet-name>mvc-dispather</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 改變默認的上下文配置 --> <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> <!-- 攔截所有請求 --> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 配置session超時時間為2小時 --> <session-config> <session-timeout>120</session-timeout> </session-config> </web-app>
在web.xml文件中，紅線圈出的幾個文件具體的配置將在后面給出。
3、resources資源目錄下各文件的配置
（1）spring.xml
也是在web.xml文件中所涉及到的配置文件，下面給出相應代碼
<?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"> <!--引入配置屬性文件 --> <context:property-placeholder ignore-unresolvable="true" location="classpath:/config.properties" /> <context:property-placeholder ignore-unresolvable="true" location="classpath:/mysite.properties" /> <!--自動掃描含有@Service將其注入為bean --> <context:component-scan base-package="com.suixue.*.service" /> </beans>
此處的兩種配置文件，將在下面詳細給出。
--》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
注意更換此文件中的數據庫名稱以及username和password
--》mysite.properties
adminPath=system/a/
只有此一行代碼，此處為瀏覽器訪問頁面時url的前綴，比如localhost:8080/system/a/login
（2）spring-mybatis.xml
同時是web.xml文件中涉及到的配置文件，代碼如下
<?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" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd "> <!-- 配置數據源 使用的是Druid數據源 --> <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="url" value="jdbc:mysql://localhost:3306/movie_management" /> <property name="username" value="suixue" /> <property name="password" value="123456" /> <!-- 初始化連接大小 --> <property name="initialSize" value="0" /> <!-- 連接池最大使用連接數量 --> <property name="maxActive" value="20" /> <!-- 連接池最小空閑 --> <property name="minIdle" value="0" /> <!-- 獲取連接最大等待時間 --> <property name="maxWait" value="60000" /> <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="33" /> <!-- 用來檢測有效sql --> <property name="validationQuery" value="${validationQuery}" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <property name="testWhileIdle" value="true" /> <!-- 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <!-- 配置一個連接在池中最小生存的時間，單位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="25200000" /> <!-- 打開removeAbandoned功能 --> <property name="removeAbandoned" value="true" /> <!-- 1800秒，也就是30分鍾 --> <property name="removeAbandonedTimeout" value="1800" /> <!-- 關閉abanded連接時輸出錯誤日志 --> <property name="logAbandoned" value="true" /> <!-- 監控數據庫 --> <property name="filters" value="mergeStat" /> </bean> <!-- myBatis文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自動掃描entity目錄, 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> dialect=mysql rowBoundsWithCount=true offsetAsPageNum=true </value> </property> </bean> </array> </property> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.suixue.**.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> <!-- 配置事務管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 注解方式配置事物 --> <!-- <tx:annotation-driven transaction-manager="transactionManager" /> --> <!-- 攔截器方式配置事物 --> <tx:advice id="transactionAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED" /> <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事務管理 --> <aop:config> <aop:pointcut id="transactionPointcut" expression="execution(* com..*service.*(..))" /> <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /> </aop:config> </beans>
應注意此處應改成自己的數據庫名稱以及登錄名和密碼
此處路徑應改成自己相應的mapper路徑，匹配其下面所有的xml文件，這里所說的xml文件中，包含的是sql語句，類似於下面的內容
另外，spring-mybatis.xml文件中下面紅色的部分應對應自己項目中的dao層接口，以使得上面剛剛提到的mapper中的xml(包含sql語句)與dao層下的文件相映射起來。
此例子中com.suixue.**.dao包下面包含java文件，該java文件不是一個類class,而是一個接口。
下面給出我一個項目中的對應關系，方便理解。
另外，還需要注意的是
此處限制了涉及數據庫增刪改查操作的時候方法名的命名限制。
此處應對應好自己項目中的service方法，有固定語法，不了解的地方請自己查閱相關資料。
這是我的service文件的結構信息。
（3）mvc-dispather-servlet.xml
同樣是在web.xml中涉及的配置文件，代碼如下
<?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"> <!-- 激活標注 --> <context:annotation-config></context:annotation-config> <!-- DispatherContext上下文，只搜索標注了@Controller的類 --> <context:component-scan base-package="com.suixue.*"> </context:component-scan> <mvc:annotation-driven /> <!-- 啟用基於mvc的HandlerMapping --> <mvc:default-servlet-handler /> <mvc:interceptors> <mvc:interceptor> <!-- 所有文件夾及其子文件夾 --> <mvc:mapping path="/system/*" /> <bean id="loginInterceptor" class=" com.suixue.system.common.LoginInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> <!-- 避免IE執行AJAX時,返回JSON出現下載文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 啟動Spring MVC的注解功能，完成請求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <!-- json轉換器 --> <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>
注意紅色區域部分，做出相應更改，其中最后的bean配置中的class,改成自己對應的bean即可，下面給出我的LoginInterceptor.java文件的具體代碼
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; } }
此處設置前綴和后綴，根據需要可以自己更改。
當當當，至此，所有的基本配置到底就結束啦，若是有不足的地方，歡迎大家多多指正。
