SSM框架——配置文件

開發環境：idea
使用的技術：ssm + maven + druid(數據庫連接池） + mysql 8.0.15 + junit

一、項目目錄結構

在resources文件夾中存放基本的配置文件

二、web.xml

<?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_3_0.xsd"
         id="WebApp_ID" version="3.0">

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>

  <!--配置加載Spring文件的監聽器-->
  <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>


  <!-- 字符編碼過濾器，一定要放在所有過濾器之前 -->
  <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>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>*.action</url-pattern>
  </filter-mapping>

  <!-- SpringMVC的前端控制器，攔截所有請求 -->
  <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-config.xml</param-value>
    </init-param>
    <!--配置服務器啓動後立即加載Spring MVC配置文件-->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.do</url-pattern> 
    <!--攔截以.do結尾的方法-->
  </servlet-mapping>

</web-app>

三、pom.xml

<?xml version="1.0" encoding="UTF-8"?>

<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">

  <url>http://www.example.com</url>

**** 前面都是項目自動生成的，注意修改

四、druid.properties(數據庫配置)

jdbc.driverClassName = com.mysql.cj.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/library?useUnicode=true&characterEncoding=utf8&userSSL=false&serverTimezone=GMT%2B8
jdbc.username = root
jdbc.password = 103624
jdbc.maxActive = 30
jdbc.initialSize = 5

五、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:util="http://www.springframework.org/schema/util"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx.xsd">

<context:property-placeholder location = "classpath:druid.properties" />

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


    <!--配置mybatis的sqlSessionFactory工廠-->
    <bean class = "org.mybatis.spring.SqlSessionFactoryBean">
        <!--引用數據源-->
        <property name = "dataSource" ref = "dataSource"/>
        <!--Mybatis配置文件位置-->
        <property name = "configLocation" value = "classpath:mybatis-config.xml" />
    </bean>

    <!--掃描Service-->
    <context:component-scan base-package = "service"/>

    <!-- 自動掃描包，並且生成mapper的實現類，生成的bean的名稱爲mapper接口的首字母小寫 -->
    <bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name = "basePackage" value="dao"/>
    </bean>

    <!-- 事務管理器 -->
    <bean id = "transactionManager" class = "org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name = "dataSource" ref = "dataSource" />
    </bean>

    <!--開啓事務註解-->
    <tx:annotation-driven transaction-manager = "transactionManager" />


</beans>

六、springmvc-config.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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.2.xsd">

    <!-- 配置包掃描器，掃描@Controller註解的類 -->
    <context:component-scan base-package="controller"/>
    <!-- 加載註解驅動 -->
    <mvc:annotation-driven/>

    <!--配置靜態資源的訪問映射，此配置中的文件，將不被前端控制器攔截 -->
    <mvc:resources location="/image/" mapping="/images/**" />

    <!-- 視圖解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--<property name="prefix" value="   "/>-->
        <property name="suffix" value=".html"/>
    </bean>
</beans>

視圖解析器注意修改成對應的前後綴

七、mybatis-config.xml

<?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>

    <!--在控制檯輸出sql語句-->
    <settings>
        <setting name= "mapUnderscoreToCamelCase" value = "true"/>
        <setting name="logImpl" value="STDOUT_LOGGING" />
    </settings>

    <!--定義別名-->
    <typeAliases>
        <package name="po"/>
    </typeAliases>


</configuration>

注意< settings>一定要在< typeAliases>前面
按照一下順序：
properties -> settings -> typeAliases -> typeHandlers -> objectWrapperFactory -> plugings -> enviroments -> databaseIdProvider -> mappers

八、log4j.properties

# Global logging configuration
log4j.rootLogger=ERROR, stdout
# MyBatis logging configuration...
log4j.logger.com.itheima.core=DEBUG
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
