手把手教你快速搭建一个SSM框架（超级详细）IDEA+Maven版

环境所需：JDK1.8、IDEA、Maven、MySQL5.7及以上等

引言：手把手教大家基于IDEA的maven环境搭建一个SSM框架、请事先装好所需要的软件工具等，SSM+Java+Maven+JSP，SSM整合JSP，mapper和实体层使用的是自动生成噢！

Java环境搭建教程：浏览器搜索https://www.bilibili.com/video/BV1BN4y1c7Fp/

以下是完整的框架案例！可以在上面上进行修改！

​

1、打开idea，新建Project，选择Maven、勾选骨架，并选中maven-archetype-webapp之后，点击next

2、创建GroupId（包名）com.flight,ArtifactId（项目名称）flight_web,然后点击next

3、选择maven的安装目录，并配置setting.xml,然后点击next，如果没有搭建maven，请搜索：https://www.bilibili.com/video/BV1BN4y1c7Fp/

4、选择安装目录，放到D盘，然点击Finish

5、open打开项目之后，在main目录下创建两个dirctory（包），分别是java和resources文件夹。

6、点击java包右击选择Mark Directory as -->Sources Root，然后 选择resouces包右击右击选择Mark Directory as -->Resources Root，就编程下面的样子了，需要手动操作的！

7、配置pom文件,在maven的pom文件配置下面的jar，然后点击Import Changes

</build></project>​

8、配置webapp下的WEB-INF下的web.xml文件，把下面的复制过去，并在WEB-INF下面建一个jsp的目录，解析的界面放在jsp目录里面。

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >​<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">  <display-name>flight_web</display-name>  <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>  <!-- 配置监听器加载spring的配置文件 -->  <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>  </filter>  <filter-mapping>    <filter-name>CharacterEncodingFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>​  <!-- 配置dispatcherServlet，来加载springmvc的配置 -->  <servlet>    <servlet-name>DispatcherServlet</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>DispatcherServlet</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>  <error-page>    <error-code>404</error-code>    <location>/WEB-INF/jsp/error.jsp</location>  </error-page></web-app>​

9、在resources目录下面配置applicationContext.xml文件，这个是Spring的配置文件。

<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/beans    http://www.springframework.org/schema/beans/spring-beans-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/context    http://www.springframework.org/schema/context/spring-context-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/tx    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">  <!--修改，业务层接口所在的包-->  <context:component-scan base-package="com.flight.service"></context:component-scan>​  <!-- 接口开发,扫描 com.ssm.core.dao包 ，写在此包下的接口即可被扫描到 -->  <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">    <property name="basePackage" value="com.flight.mapper" />  </bean>  <!-- 配置数据库连接池 -->  <!-- 加载配置文件 -->  <context:property-placeholder location="classpath:db.properties"/>  <!-- 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sqlsessionFactory -->  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">    <property name="configLocation" value="classpath:SqlMapConfig.xml"></property>    <property name="dataSource" ref="dataSource"></property>    <!--修改，实体类的包-->    <property name="typeAliasesPackage" value="com.flight.entity"></property>    <!--修改，DAO接口和映射配置文件的包-->    <property name="mapperLocations" value="classpath:com/flight/mapper/*.xml"></property>  </bean>  <!-- 配置扫描包，加载mapper代理对象 -->  <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">    <property name="basePackage" value="com.flight.mapper"></property>    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>  </bean>​  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">    <!-- 数据源 -->    <property name="dataSource" ref="dataSource"></property>  </bean>  <!-- 通知 -->  <tx:advice id="txAdvice" transaction-manager="transactionManager">    <tx:attributes>      <!-- 传播行为 -->      <tx:method name="save*" propagation="REQUIRED"/>      <tx:method name="insert*" propagation="REQUIRED"/>      <tx:method name="add*" propagation="REQUIRED"/>      <tx:method name="create*" propagation="REQUIRED"/>      <tx:method name="delete*" propagation="REQUIRED"/>      <tx:method name="update*" propagation="REQUIRED"/>            <tx:method name="find*" propagation="SUPPORTS" read-only="true"/>      <tx:method name="select*" propagation="SUPPORTS" read-only="true"/>      <tx:method name="get*" propagation="SUPPORTS" read-only="true"/>    </tx:attributes>  </tx:advice>  <!-- 切面 -->  <aop:config>    <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.flight.service.*.*(..))"/>  </aop:config></beans>

10、在resources目录下面配置db.propretie文件，这个是数据库的配置文件。

jdbc.driver=com.mysql.cj.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/db_flight_web?useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true&useUnicode=true&characterEncoding=utf-8jdbc.username=rootjdbc.password=123456

11、接着在resources目录下面配置generatorConfig.xml文件，这个是对象映射框架的配置文件，可以生成自动生成mapper和实体类，不需要手动创建。

注意：将mysql-connector-java-5.1.46.jar放到D盘里面，可以是其他版本的，不然无法自动生成！

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE generatorConfiguration        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration>    <!-- 数据库驱动:选择你的本地硬盘上面的数据库驱动包-->    <classPathEntry  location="D:\mysql-connector-java-5.1.46.jar"/>    <context id="DB2Tables"  targetRuntime="MyBatis3">        <commentGenerator>            <property name="suppressDate" value="true"/>            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->            <property name="suppressAllComments" value="true"/>        </commentGenerator>        <!--数据库链接URL，用户名、密码 -->        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/db_flight_web"                        userId="root" password="123456">        </jdbcConnection>        <javaTypeResolver>            <property name="forceBigDecimals" value="false"/>        </javaTypeResolver>        <!-- 生成模型的包名和位置-->        <javaModelGenerator targetPackage="com.flight.entity" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>            <property name="trimStrings" value="true"/>        </javaModelGenerator>        <!-- 生成映射文件的包名和位置-->        <sqlMapGenerator targetPackage="com.flight.mapper" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>        </sqlMapGenerator>        <!-- 生成DAO的包名和位置-->        <javaClientGenerator type="XMLMAPPER" targetPackage="com.flight.mapper" targetProject="src/main/java">            <property name="enableSubPackages" value="true"/>        </javaClientGenerator>        <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->​​​        <table tableName="t_admin" domainObjectName="Admin">            <property name="useActualColumnNames" value="true"></property>        </table>​​​        </context></generatorConfiguration>

12、接着在resources目录下面配置log4j.properties文件，这个是配置日志文件。

log4j.rootLogger=DEBUG, Console  #Consolelog4j.appender.Console=org.apache.log4j.ConsoleAppender  log4j.appender.Console.layout=org.apache.log4j.PatternLayout  log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n  log4j.logger.java.sql.ResultSet=INFO  log4j.logger.org.apache=INFO  log4j.logger.java.sql.Connection=DEBUG  log4j.logger.java.sql.Statement=DEBUG  log4j.logger.java.sql.PreparedStatement=DEBUG  

13、接着在resources目录下面配置springmvc.xml文件，这个是配置SpringMVC的配置文件。

<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/beans    http://www.springframework.org/schema/beans/spring-beans-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/context     http://www.springframework.org/schema/context/spring-context-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/tx    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">  <!-- 配置包扫描器，扫描@Controller注解的类 -->  <context:component-scan base-package="com.flight.controller"></context:component-scan>  <!-- 配置注解驱动 -->  <mvc:annotation-driven></mvc:annotation-driven>  <mvc:resources  location="/static/" mapping="/resource/**"/>    <!-- 视图解析器 -->  <bean    class="org.springframework.web.servlet.view.InternalResourceViewResolver">    <property name="prefix" value="/WEB-INF/jsp/" />    <property name="suffix" value=".jsp" />  </bean>  <!-- 不拦截资源文件 -->  <mvc:default-servlet-handler/>  <!-- 附件解析器 -->  <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">    <!-- 1G: -->    <property name="maxUploadSize" value="1073741824"></property>  </bean>​<mvc:interceptors>    <mvc:interceptor>      <!-- 拦截所有mvc控制器 -->      <mvc:mapping path="/login"></mvc:mapping>      <!-- mvc:exclude-mapping是另外一种拦截，它可以在你后来的测试中对某个页面进行不拦截，这样就不用在-->      <bean class="com.flight.intercepter.LoginIntercepter"></bean>    </mvc:interceptor>  </mvc:interceptors></beans>

14、接着在resources目录下面配置SqlMapConfig.xml文件，配置分页插件，和驼峰设置！

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>  <settings>       <setting name="mapUnderscoreToCamelCase" value="true"/>   </settings>  <plugins>    <!-- 配置分页插件 -->    <plugin interceptor="com.github.pagehelper.PageInterceptor"></plugin>  </plugins></configuration>

15、配置LoginIntercepter进行登录拦截！,比如只有登录之后才可以访问后台，如果没有登录则不可以访问！

package com.flight.intercepter;​import com.flight.entity.Admin;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView;​import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;​​public class LoginIntercepter implements HandlerInterceptor {    @Override    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {​        // 获取请求的URL        String url = request.getRequestURI();        // URL:除了login.jsp是可以公开访问的，其它的URL都进行拦截控制        if(url.indexOf("/login")>=0){            return true;        }        // 获取Session        HttpSession session = request.getSession();        Admin admin = (Admin) session.getAttribute("admin");        // 判断Session中是否有用户数据，如果有，则返回true,继续向下执行        if(admin != null){            return true;        }        // 不符合条件的给出提示信息，并转发到登录页面        request.setAttribute("msg", "您还没有登录，请先登录！");        request.getRequestDispatcher("/WEB-INF/jsp/login.jsp")                .forward(request, response);        return false;​    }​    @Override    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {​    }​    @Override    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {​    }}​

16、自动生成实体和mapper，双击mybaits-generator:generate！即可生成！

17、配置tomcat使用自带插件，双击tomcat7:run即可，非常快速，然后访问路径进入到登陆界面！
