IDEA中使用Maven构建SSM项目

文章目录

第一步创建Maven webapp项目

1. 首先,新建工程;

在这里插入图片描述

2. 选择Maven标签,然后勾选上[Create from archetype],选择webapp,点击next;

3. 填写上[GroupId]和[ArtifactId],点击next;

在这里插入图片描述

GroupId:项目组织唯一标识,实际对应Java的包结构,也就是main目录下Java的目录结构;
AritifactId:项目的唯一标识,实际对应项目的名称,就是项目根目录的名称.

4. 填写Maven的配置信息(写自己本地的目录):Maven所在的目录,使用settings文件目录,本地仓库目录,之后点击next;

在这里插入图片描述

5. 设置并确认项目名称,及项目所在目录,最后点击finish.等待项目初始化.

6. 等待项目初始化,构建完成后,控台就会有创建成功的提示信息.我们把提示信息[Enable Auto-Import]点上,这个提示会在每次pom.xml文件有改动时出现,选上后会自动导入,省得麻烦.

第二步搭建项目目录结构

1. 下面就是Maven工程初始化的webapp的默认目录结构:

在这里插入图片描述

注意:在这里面创建的webapp项目默认没有java源文件,resources资源文件,和test目录的.

2. 遵循Maven的统一项目结构,我们搭建出项目的完整目录结构如下图:

在这里插入图片描述
在这里,我们创建完普通的目录后,
为了让IDEA识别不同的目录作用,我们需要在IDEA 中右键刚刚创建的目录后选择[Make Directory as]选项进行目录的设置.

3. 上面的目录结构建好并配置后,还需要设置[file]-[Project Structure],让IDEA有自动识别目录的作用.

4. 设置好后点击OK,到这儿就完成了项目目录的搭建.

第三步添加配置文件内容

1. 在[pom.xml]文件中导入依赖的jar包:spring、springmvc、mybatis、数据库连接池、驱动包、其他(jstl,servlet-api,junit等按需导入即可)

2.SpringMVC前端控制器的配置:

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context
    https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc
    https://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--    springMVC的配置文件，包含网站跳转的控制，配置-->
    <context:component-scan base-package="com.atguigu" use-default-filters="false">
<!--        只扫描控制器-->
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
<!--    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>
<!--    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更高级一些的功能,JSR303校验，快捷的ajax...映射动态请求-->
    <mvc:annotation-driven/>
</beans>

3.Spring的配置:

<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!--    扫描包,除了控制器不要 其他都要  与springMVC不同-->
    <context:component-scan base-package="com.atguigu">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <!--    Spring的配置文件 这里主要配置和业务逻辑有关的-->
    <!--    数据源，事务控制-->
    <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全局配置文件位置-->
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
        <property name="dataSource" ref="pooledDataSource"></property>
        <!--    指定mapper文件位置-->
        <property name="mapperLocations" value="classpath:mapper/*.xml"></property>

    </bean>

<!--    配置一个可以执行批量的SQL Session-->
<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>
<!--    事务控制配置-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="pooledDataSource"></property>
    </bean>
    <!--开启基于注解的事务，使用xml配置形式的事务（必要主要的都是使用配置式）  -->
<aop:config>
<!--    切入点表达式-->
    <aop:pointcut id="txPoint" expression="execution(* com.atguigu.crud.service..*(..))"/>
<!--    配置事务增强-->
    <aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"></aop:advisor>
</aop:config>
<!--    配置事务增强，事务如何切入-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
<!--            所有方法都是事务方法-->

<!--            以get开始的所有方法-->
            <tx:method name="get" read-only="true"/>
        </tx:attributes>
    </tx:advice>

    <!-- Spring配置文件的核心点（数据源、与mybatis的整合，事务控制） -->

</beans>

4.数据源的配置:

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm_crud?characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true 
jdbc.driverClass=com.mysql.cj.jdbc.Driver
jdbc.user=root
jdbc.password=root

5.mybatis的配置:

<?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>
    <settings>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>
    <typeAliases>
        <package name="com.atguigu.crud.bean"/>(即 需要注入的实体类  entity)
    </typeAliases>
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
<!--    后续需要再加,分页查询时参数合理化-->
            <property name="reasonable" value="true"/>
        </plugin>
    </plugins>
</configuration>

6.web.xml的配置:

<?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">


  <display-name>Archetype Created Web Application</display-name>
<!--  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>dispatcherServlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

<!--  3、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>
      <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>
<!--  使用Rest风格的URI,将页面普通的post请求转为指定的delete或者put请求-->
  <filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <filter>
    <filter-name>HttpPutFormContentFilter</filter-name>
    <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>HttpPutFormContentFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

以上就完成了基本的相关配置:

添加进了 SSM 项目所需要的 jar 包
配置好了 spring/mybatis/spring MVC 的相关配置信息

接下来就可以测试了.

第四步测试
