SSM環境的搭建

 雖然如今流行SpringBoot了，可是對於之前的SSM配置地獄的框架搭建整合作一個簡單的Demo

首先建立新的項目，選擇Maven管理咱們的依賴 如圖所示：

　

固然我是爲了作列子，因此採用的中文，

而後選擇本身的maven地址，這裏稍微注意的是，Maven默認讀取的是 .m2/setting.xml做爲配置文件，

　　我改動了配置文件的相關下載和配置文件存儲路徑，因此我選用我本身的配置文件做爲啓動配置

而後等待下載，下載完以後，項目構建以下：

而後建立java 文件夾，做爲咱們存放代碼的文件，並在下面建立出響應的 package 模塊 

最後就是這樣的

——————————前期的基本準備工做到此爲止，下面開始搭建環境————————————

先把最後的樣子貼出來，能夠先把結構搭起來，再填充內容：

 1:優先配置 maven的 pom.xml  導入相關依賴

而後配置web.xml　

 <!-- 配置監聽器加載spring -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- 配置SpringBeans的配置文件所在目錄-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/applicationContext.xml</param-value>
  </context-param>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <!-- 修改默認springmvc加載的配置文件路徑 -->
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/springmvc.xml</param-value>
    </init-param>
    <!-- 配置Spring的啓動時機 >=0隨着容器一塊兒啓動  <0第一次來請求時啓動 -->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- 配置編碼方式-->
  <filter>
    <filter-name>encodingFilter</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>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern> </filter-mapping> 　　<!--設置一個默認訪問的頁面--> <welcome-file-list> <welcome-file>/WEB-INF/index.jsp</welcome-file> </welcome-file-list>

web.xml中指定的文件，咱們循序漸進的造出來

依次爲：applicationContext.xml

<?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-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">

    <!-- 配置註解掃描 -->
    <context:component-scan base-package="com.test.ssm.service" />

    <!-- 加載數據源所須要的參數配置文件 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!-- 配置 數據源 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
    </bean>

    <!-- 讓Spring管理myBatis的會話工廠 SqlsessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" >
       <!--注入數據庫鏈接池-->
        <property name="dataSource" ref="dataSource"/>
        <!--掃描Model包，使用別名-->
        <property name="typeAliasesPackage" value="com.test.ssm.model"/>
        <!-- 掃描sql配置文件： mapper須要的xml文件 -->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>

    <!-- 配置掃描Dao接口包，動態實現Dao接口，注入到spring容器中 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入Dao-->
        <property name="basePackage" value="com.test.ssm.dao"/>
        <!--注入sqlSession工廠-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>

    <!--配置事務管理器-->
    <bean id="trancationManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--開啓聲明式事務-->
    <tx:annotation-driven transaction-manager="trancationManager"/>
</beans>

其次：springmvc.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
 4        xmlns:context="http://www.springframework.org/schema/context"
 5        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
 6        xsi:schemaLocation="http://www.springframework.org/schema/beans
 7       http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
 8       http://www.springframework.org/schema/mvc
 9       http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
10       http://www.springframework.org/schema/context
11       http://www.springframework.org/schema/context/spring-context-3.2.xsd">
12 
13     <!-- 1.配置註解掃描位置 -->
14     <context:component-scan base-package="com.test.ssm.controller" />
15 
16     <!-- 2.配置註解處理映射 3.配置適配器-->
17     <mvc:annotation-driven />
18 
19     <!-- 4.配置springmvc視圖解析器 視圖解析器解析的視頻路徑爲：前綴 + 後綴 -->
20     <bean 21             class="org.springframework.web.servlet.view.InternalResourceViewResolver">
22         <property name="prefix" value="/WEB-INF/views" />
23         <property name="suffix" value=".jsp" />
24     </bean>
25 </beans>

而後   applicationContext.xml  又依賴新的配置文件，逐一配置出來

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

logback.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <configuration debug="true">
 3     <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
 4         <encoder>
 5             <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
 6         </encoder>
 7     </appender>
 8     <root level="INFO">
 9         <appender-ref ref="STDOUT"/>
10     </root>
11 </configuration>

運行服務器，看看效果

自動跳轉到了默認的index.jsp  

 

測試一下數據庫，查詢一點數據看看可否連通

發現本身都不太熟悉了，但願之後再也用不上！
