篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SSM的搭建相关的知识，希望对你有一定的参考价值。
1.首先是工具的准备。
- eclipse
- jdk1.7
- maven 3.5.4
- tomcat 8.5
2.工具环境的搭建
首先，new建立选择maven project工程，勾选simple project,next后如下图所示，goup id起名为com.blog,artifact id为ssm-build,packing为war。
点击finish后完成maven工程的创建。如下图所示，目录webapp下，没有我们的WEB-INF,web.xml等。
我们可以右击项目properties，搜素project facets，去除Dynamic Web Module选项apply，再次勾选，可进行自动生成设置，如下图所示，生成目录为src/main/webapp，勾选生成，ok即可完成，项目的目录搭建。
3.准备项目所需的环境对应的配置文件等
1.引入pom相关依赖,依赖可从maven repository官网进行查询配置
<dependencies>
<!--引入spring相关依赖 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<!-- Spring-Jdbc -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<!--Spring-test -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<!-- Spring面向切面编程 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<!--MyBatis -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.4.2</version>
</dependency>
<!-- MyBatis整合Spring的适配包 -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.3.1</version>
</dependency>
<!-- 数据库连接池、驱动 -->
<dependency>

</dependency>
<!--mysql连接驱动 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.41</version>
</dependency>
<!-- （jstl，servlet-api，junit） -->
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
<!-- junit -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
</dependencies>
2.配置resource.properties数据库文件
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf-8 jdbc.username=root jdbc.password=root
3.配置springMVC.xml文件，与前端交互的。
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"> <!--SpringMVC的配置文件，包含网站跳转逻辑的控制，配置 --> <context:component-scan base-package="com.blog.controller"/> <!--两个标准配置 --> <!-- 将springmvc不能处理的请求交给tomcat --> <mvc:default-servlet-handler/> <!-- 能支持springmvc更高级的一些功能，JSR303校验，快捷的ajax...映射动态请求 --> <mvc:annotation-driven/> <!--配置视图解析器，方便页面返回 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>
4.创建applicaitonContext.xml文件用于我们的业务逻辑
<?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:mvc="http://www.springframework.org/schema/mvc" 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/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"> <!-- 属性读取 --> <context:property-placeholder location="classpath:resource.properties" /> <context:component-scan base-package="com.blog"> <!-- 扫描符合@Controller的类 --> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 数据库连接池 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="driverClassName" value="${jdbc.driver}" /> <property name="maxActive" value="10" /> <property name="minIdle" value="5" /> </bean> <!--================== 配置和MyBatis的整合=============== --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 指定mybatis全局配置文件的位置 --> <property name="dataSource" ref="dataSource"></property> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.blog" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> <!-- ===============事务控制的配置 ================--> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 拦截器方式配置事物 --> <tx:advice id="transactionAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="append*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="modify*" propagation="REQUIRED" /> <tx:method name="edit*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="repair" propagation="REQUIRED" /> <tx:method name="delAndRepair" propagation="REQUIRED" /> <tx:method name="get*" propagation="SUPPORTS" /> <tx:method name="find*" propagation="SUPPORTS" /> <tx:method name="load*" propagation="SUPPORTS" /> <tx:method name="search*" propagation="SUPPORTS" /> <tx:method name="datagrid*" propagation="SUPPORTS" /> <tx:method name="*" propagation="SUPPORTS" /> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="transactionPointcut" expression="execution(* com.blog.service.*.*(..))" /> <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /> </aop:config> </beans>
上面的四个文件是必备步骤,接下来配置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_2_5.xsd" id="WebApp_ID" version="2.5"> <!--1、启动Spring的容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--2、springmvc的前端控制器，拦截所有请求 --> <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:springMVC.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!-- 默认访问的页面 --> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <!-- 3、字符编码过滤器，一定要放在所有过滤器之前 --> <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><!--是否强制使用encoding编码 --> <param-name>forceRequestEncoding</param-name> <param-value>true</param-value> </init-param> <init-param><!--是否强制使用encoding编码 --> <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>
到这里我们已经基本配置完毕了，有什么需求，可以进行任意的增加，接下来我们编辑网页部分，在webapp下简历index.jsp文件，这是web.xml配置的默认访问位置
为了使页面更好看
引入bootstrap美化页面
如图，在webapp目录下建立了static目录，放入了jquery以及bootstrap，这些官网可进行直接下载。
在index.jsp中引入这些jquery和bootstrap样式。
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

</head>
<body>
<form style="margin-top:18%;margin-left:38%" >
<div class="form-group">
<label for="exampleInputEmail1">用户名</label>
<input type="email" style="width:500px;" class="form-control" id="exampleInputEmail1" placeholder="Email">
</div>
<div class="form-group">
<label for="exampleInputPassword1">密码</label>
<input type="password" style="width:500px;" class="form-control" id="exampleInputPassword1" placeholder="Password">
</div>
<div class="checkbox">
<label>
<input type="checkbox">记住密码
</label>
</div>
<button type="submit" style="width:500px;" class="btn btn-success">登录</button>
</form>
</body>
</html
把项目加载到tomcat上运行，到此已经完成最基本的ssm环境运行了，成功页面如下图所示。
