一，在resource 文件夹下面新建两个文件夹 conf 和mapper ,前者用来存放相关的配置文件，后者用来存放操作中各业务模块所需要用到的查询语句。

spring_aop.xml AOP 应用配置

<?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:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:jms="http://www.springframework.org/schema/jms" xmlns:lang="http://www.springframework.org/schema/lang" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:util="http://www.springframework.org/schema/util" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd http://www.springframework.org/schema/jms http://www.springframework.org/schema/jms/spring-jms-3.2.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd "> <!-- AOP配置应用 --> <!-- 开启组件扫描,扫描切面组件 --> <context:component-scan base-package="com.sjh.cloud_note.aspect"/> <!-- 开启AOP注解配置,支持切面,通知,切入点注解标记 --> <aop:aspectj-autoproxy /> </beans>

 

spring_mvc.xml 组件扫描配置，会在项目中扫描所有加注解的地方

<?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:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:jms="http://www.springframework.org/schema/jms" xmlns:lang="http://www.springframework.org/schema/lang" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd http://www.springframework.org/schema/jms http://www.springframework.org/schema/jms/spring-jms-3.2.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd "> <!-- 开启组件扫描 --> <context:component-scan base-package="com.sjh.cloud_note"/> <!-- 开启注解驱动 --> <mvc:annotation-driven/> </beans>

 spring_mybatis.xml 数据库连接配置,文件中的配置内容需要根据各自情况进行修改，如数据库登录名和登录密码

<?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:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:jms="http://www.springframework.org/schema/jms" xmlns:lang="http://www.springframework.org/schema/lang" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd http://www.springframework.org/schema/jms http://www.springframework.org/schema/jms/spring-jms-3.2.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd "> <!-- 配置数据库连接参数及连接池 --> <bean id="dbcp" class="org.apache.commons.dbcp.BasicDataSource"> <property name="username" value="root"/> <property name="password" value="sasa"/> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/cloud_note?serverTimezone=GMT+8"/> </bean> <!-- 配置SqlSessionFactory --> <bean id="ssf" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dbcp"/> <property name="mapperLocations" value="classpath:mapper/*.xml"/> </bean> <!-- 配置mapper扫描 --> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.sjh.cloud_note.dao"/> </bean> </beans>

spring_transcation.xml 事务注解配置

<?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:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:jms="http://www.springframework.org/schema/jms" xmlns:lang="http://www.springframework.org/schema/lang" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:util="http://www.springframework.org/schema/util" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd http://www.springframework.org/schema/jms http://www.springframework.org/schema/jms/spring-jms-3.2.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd "> <!-- Spring事务管理 --> <!-- 定义事务管理Bean --> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dbcp"></property> </bean> <!-- 开启事务注解配置@transactional --> <!-- 开启transaction标记，将标记作用在具体方法上 --> <tx:annotation-driven transaction-manager="txManager"/> </beans>

 

 

二、配置 Web.xml

修改项目默认页，项目过滤拦截器，当项目运行时，指定打开的页面，将 welcome-file 标签内容替换成你想要的默认打开的页面名称。

<?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_2_5.xsd" version="2.5"> <display-name>cloud_note</display-name> <welcome-file-list> <welcome-file>log_in.html</welcome-file> </welcome-file-list> <servlet> <servlet-name>mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:conf/spring_*.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>

红色框内1 和 2 的名称要保持一致 

 红色框3 表示当我们向后台controller 发送请求是，请求 url 必须带后缀名，并且后缀名为.do,可根据实际应用进行更改

 

 红色框4 则是比较重要的地方，它代表当项目启动时要去初始化加载的一些文件 ，包括 数据库配置文件、事务配置文件，AOP配置应用，组件扫描等，路径就是我们操作一下面事先配置好的文件。classpath:conf/spring_*.xml 意思就是会在项目路径conf文件夹下面加载所有文件名以 “spring_”开头的xml 文件。

 配置到这里项目已经配置完毕，接下来就是具体项目实际功能的实现。
