maven的ssm搭建，簡單版
阿新 • • 發佈：2018-11-13
（1）新建一個maven專案叫做ssmcurd
（2）web.xml裡面要匯入相關jar包：
<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>hua</groupId> <artifactId>ssmcurd</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <failOnMissingWebXml>false</failOnMissingWebXml> </properties> <!-- 引入專案依賴的jar包 --> <dependencies> <!-- springmvc、spring --> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.7.RELEASE</version> </dependency> <!-- spring-jdbc --> <!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.7.RELEASE</version> </dependency> <!-- spring 面向切面程式設計 --> <!-- https://mvnrepository.com/artifact/org.springframework/spring-aspects --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.3.7.RELEASE</version> </dependency> <!-- mybatis --> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.2</version> </dependency> <!-- mybatis整合spring的適配包 --> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.1</version> </dependency> <!-- 資料庫連線池 --> <!-- https://mvnrepository.com/artifact/c3p0/c3p0 --> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> </dependency> <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.41</version> </dependency> <!-- jstl --> <!-- https://mvnrepository.com/artifact/jstl/jstl --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope><!-- tomcat中也有servlet-api包,provided表明該包只在編譯和測試的時候用，所以，當啟動tomcat的時候，這個包自動剔除，就不會衝突了 --> </dependency> <!-- Junit --> <!-- https://mvnrepository.com/artifact/junit/junit --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <!-- jackson 返回json字串的 支援 --> <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.8.8</version> </dependency> <!--其他jar包--> <!-- pageHelper --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>5.0.0</version> </dependency> </dependencies> </project>
（3）在resource下建立一個數據庫配置檔案dbconfig.properties：
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm_curd?useUnicode=true&characterEncoding=UTF-8
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=1234567890
（4）在resource下建立一個applicationContext.xml，配置spring：
<?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" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"> <!-- spring的配置檔案，這裡主要配置和業務邏輯有關的 ,比如資料來源，事務控制，配置和mybatis的整合（mybatis配置檔案的位置，mapper.xml位置，dao介面實現的位置，批量操作SqlSession）--> <!-- 核心點：資料來源，與mybatis的整合，事務控制 --> <!-- 註解掃描 --> <context:component-scan base-package="hua" > <!-- 不掃控制器的--> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 引入外部檔案 ,需要namespaces加個context--> <context:property-placeholder location="classpath:dbconfig.properties"/> <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property> <property name="driverClass" value="${jdbc.driverClass}"></property> <property name="user" value="${jdbc.user}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!-- 配置和mybatis的整合 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 指定mybatis全域性配置檔案的位置 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <property name="dataSource" ref="pooledDataSource"></property> <!-- 指定mybatis、mapper檔案的位置 --> <property name="mapperLocations" value="classpath:mapper/*.xml"></property> </bean> <!-- 配置掃描器，將mybatis介面的實現加入到ioc容器中。因為mybatis介面的實現是一個代理物件 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 掃描所有的dao介面的實現，加入到ioc容器中 --> <property name="basePackage" value="hua.dao"></property> </bean> <!-- 配置一個可以執行批量的SqlSession --> <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate" > <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg> <constructor-arg name="executorType" value="BATCH"></constructor-arg> </bean> <!-- 事物控制配置 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 控制資料來源 --> <property name="dataSource" ref="pooledDataSource"></property> </bean> <!-- 開啟基於註解的事務，使用xml配置形式的事務，（推薦比較重要的都是使用配置式） --> <aop:config> <!-- 切入點表示式 service下的所有類的所有方法都想來控制事務--> <aop:pointcut expression="execution(* hua.service..*())" id="txPoint"/> <!-- 配置事務增強：事務如何切入規則指定，切入方法指定--> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/> </aop:config> <!-- 配置事務增強，也就是配置事務如何切入 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 這個切入點切入的所有方法都是事務方法 --> <tx:method name="*"/> <!-- 以get開始的所有方法都是查詢 --> <tx:method name="get*" read-only="true"/> </tx:attributes> </tx:advice> </beans>
（5）在resource下建立一個mybatis-config.xml檔案，配置mybatis
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <typeAliases> <package name="hua.bean"/> </typeAliases> <!-- 在 MyBatis 的xml 中配置攔截器外掛 --> <plugins> <!-- com.github.pagehelper為PageHelper類所在包名 --> <plugin interceptor="com.github.pagehelper.PageInterceptor"> <!-- 分頁引數合理化 --> <property name="reasonable" value="true"/> </plugin> </plugins> </configuration>
（6）在WEB—INF下面建立dispatcherServlet-servlet.xml，配置springmvc
<?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"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<!-- springmvc的配置檔案、包含網站的跳轉邏輯的控制、配置 -->
<!-- 註解掃描 -->
<context:component-scan base-package="hua" use-default-filters="false">
<!-- 只掃描控制器 ,所有標了控制器註解的就是控制器，只掃這些-->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 配置檢視解析器。方便頁面返回 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 兩個標準配置 -->
<!-- 將springmvc不能處理的請求交給tomcat，實現動態靜態資源都能訪問成功 -->
<mvc:default-servlet-handler/>
<!-- 能支援springmvc更高階的一些功能，比如基於jsr303的校驗，快捷的ajax請求，更重要的是對映動態請求 -->
<mvc:annotation-driven/>
</beans>
（7）在web.xml配置
<?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" id="WebApp_ID" version="2.5">
<!-- 1、啟動Spring的容器 -->
<!-- needed for ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- Bootstraps the root web application context before servlet initialization -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 2、springmvc的前端控制器，攔截所有請求 -->
<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Map all requests to the DispatcherServlet for handling -->
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 3、字元編碼過濾器,攔截所有請求,一定要在所有過濾器之前 -->
<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>forceRequestEncoding</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>forceResponseEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
（8）專案結構如下：
補充：
<%
pageContext.setAttribute("Pro_Path", request.getContextPath());
%>
<!-- 注意：web路徑：
不以/開始的相對路徑，找資源，以當前資源的路徑為基準，經常容易出問題
以/開始的相對路徑，找資源，以伺服器的路徑為標準(http://localhost:3306/)，然後再加上專案名才能找到
-->
<script src="${Pro_Path }/static/jquery/jquery-2.0.3.min.js"></script>
