利用idea搭建 maven+SpringMVC開發環境

準備工做:安裝idea編輯器，配置好maven環境（idea自帶maven環境）和Java環境

一、打開idea編輯器

二、單擊「Create New Project」

三、選擇「maven」

四、勾選「Create from archetype」 

五、找到並選擇「maven-archetype-webapp」

六、點擊下一步「next」

七、填寫項目信息

八、點擊下一步「next」，進入maven信息頁面，此處能夠修改maven配置文件，安裝路徑等

九、配置完成後點擊下一步「next」，出現項目名和項目在本地的存放路徑

十、點擊「finish」完成項目項目與maven環境搭建，完成後項目結構如圖所示

十一、pom.xml依賴

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  </dependencies>
  <build>
    <finalName>permission</finalName>
  </build>
</project>

十二、配置web.xml

<!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>
  <display-name>Archetype Created Web Application</display-name>
  <!--爲spring配置一個監聽器，用於監聽spring-bean上下文加載-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--spring beans 配置文件所在的目錄-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!--springMVC 配置-->
  <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <!--「/」只攔截請求  如 /index /add 不攔截頁面 靜態文件如/index.jsp /style.css. "/*"全攔截-->
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!--指定編碼-->
  <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>
    <!--是否強制編碼-->
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <!--druid監控-->
  <servlet>
    <servlet-name>DruidStatServlet</servlet-name>
    <servlet-class>com.alibaba.druid.support.http.StatViewFilter</servlet-class>
    <init-param>
      <param-name>loginUsername</param-name>
      <param-value>druid</param-value>
    </init-param>
    <init-param>
      <param-name>loginPassword</param-name>
      <param-value>123456</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>DruidStatServlet</servlet-name>
    <url-pattern>/sys/druid/*</url-pattern>
  </servlet-mapping>
  
  <filter>
    <filter-name>DruidStatFilter</filter-name>
    <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
    <init-param>
      <param-name>exclusions</param-name>
      <param-value>*.js,*.css,*.jpg,*.png,*.ico,*.gif,/sys/druid/*</param-value>

  </filter>
  <filter-mapping>
    <filter-name>DruidStatFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

1三、springmvc配置"spring-mvc.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"

		http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
		http://www.springframework.org/schema/mvc
		http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
		http://www.springframework.org/schema/context
		http://www.springframework.org/schema/context/spring-context-4.0.xsd">
    <!--開啓上下文註解-->
    <context:annotation-config/>
    <!--啓動註解驅動的springmvc功能-->
    <mvc:annotation-driven/>
    <!--啓動包掃面功能-->
    <context:component-scan base-package="com.hz1202.controller"/>

        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

1四、spring配置「application.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: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/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--外部properties文件-->

        <property name="driverClassName" value="${db.driverClassName}"/>
        <property name="url" value="${db.url}"/>
        <property name="username" value="${db.username}"/>
        <property name="password" value="${db.password}"/>
        <property name="initialSize" value="3"/>
        <property name="minIdle" value="3"/>
        <property name="maxActive" value="20"/>
        <property name="maxWait" value="60000"/>
        <property name="filters" value="stat,wall"/>
    </bean>
    <!--配置sessionfactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--指定mybatis配置文件-->
       <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <!--指定數據源-->
       <property name="dataSource" ref="datasource"/>
        <!--指定mapper.xml文件位置-->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>

    <!--指定dao位置-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.hz1202.dao"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>

    <!--事務-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="datasource"/>
    </bean>
    <!--事務註解-->
    <tx:annotation-driven transaction-manager="transactionManager"/>
    <!--druid監控-->
    <bean id="stat-filter" class="com.alibaba.druid.filter.stat.StatFilter">
        <property name="slowSqlMillis" value="3000"/>
        <property name="logSlowSql" value="true"/>
        <property name="mergeSql" value="true"/>
    </bean>
    <bean id="wall-filter" class="com.alibaba.druid.wall.WallFilter">
        <property name="dbType" value="mysql"/>
    </bean>
</beans>

1五、mybatis配置「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>
    <!-- setting 遲延加載  二級緩存 （不用）   分佈式緩存  -->
    <settings>
        <!--<setting name="logImpl" value="STDOUT_LOGGING"/>-->
        <setting name="useGeneratedKeys" value="true"/>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>

    <!-- 別名 -->
    <!--<typeAliases>
        <package name="com.lg.core.bean"/>
    </typeAliases>-->


    <plugins>
        <!-- com.github.pagehelper爲PageHelper類所在包名 -->
        <plugin interceptor="com.github.pagehelper.PageInterceptor">

        </plugin>
    </plugins>

</configuration>

1六、日誌文件配置「logback.xml」

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="60 seconds">
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!--指定日誌輸出格式-->
        <encoder>
            <pattern>%d{yyyy-MM-d HH:mm:ss} [%thread] %-5level %logger -%msg%n</pattern>
        </encoder>
    </appender>
    <!--<appender name="permission" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${catalina.home}/logs/permission.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>${catalina.home}/logs/permission.%d{yyyy-MM-d}.log.gz</FileNamePattern>
        </rollingPolicy>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%d{yyyy-MM-d HH:mm:ss} [%thread] %-5level %logger -%msg%n</pattern>
        </layout>
    </appender>
    <logger></logger>-->
    <!--TRACE < DUBUG < INFO < WARN < ERROR-->
    <root level="INFO">
        <appender-ref ref = "STDOUT"/>
    </root>
</configuration>

至此：環境搭建完成
