idea環境基于maven整合ssm

轉自：https://blog.csdn.net/godwei_ding/article/details/76777240

1.首先建立maven項目 

選擇建立maven項目并勾選Create from archetype并選擇webapp進行項目的建構，然後點選next

填寫項目相關資訊： 

GroupID 是項目組織唯一的辨別符，實際對應JAVA的包的結構，是main目錄裡java的目錄結構。 

ArtifactID是項目的唯一的辨別符，實際對應項目的名稱，就是項目根目錄的名稱。 

設定好之後點選next。

選擇maven，可以選擇本地的maven或者使用idea自帶的maven進行建立。然後點選next。

這裡配置項目的名稱，直接finish就行。

2.包結構的設定 

自己手動建立項目包，建立好後的項目結構如下圖所示。 

這是我們是不能再Java目錄下直接建立Java檔案的，我們需要将包的屬性改為source。如下圖所示。點選左上角的file然後點選project Structs然後點選modules将mian下的Java檔案夾标記為source，resources檔案夾标記為resource。将test下的Java标記為test，resources标記為resource。 

3.配置檔案

3.1 首先配置pom.xml。由于用maven來管理項目，是以相關依賴我們不必再自己手動導入。而是用pom.xml配置相關jar包。下面是簡易的pom.xml配置

pom.xml

<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/maven-v4_0_0.xsd">

  <version>1.0-SNAPSHOT</version>
  <name>web-ssm Maven Webapp</name>
  <url>http://maven.apache.org</url>


  <properties>
    <!-- 指定編碼格式 -->
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

    <!-- 配置相關jar包的版本 -->
    <spring.version>4.3.4.RELEASE</spring.version>
    <aspectj.version>1.8.9</aspectj.version>
    <mybatis.version>3.4.1</mybatis.version>
    <mybatis-spring.version>1.3.0</mybatis-spring.version>
    <jdbc.version>5.1.35</jdbc.version>
    <fastjson.version>1.2.23</fastjson.version>
    <log4j.version>2.7</log4j.version>
    <servlet.version>3.0-alpha-1</servlet.version>
  </properties>



  <dependencies>
    <!--添加junit依賴-->

    </dependency>
  </dependencies>

  <build>
    <finalName>web-ssm</finalName>
  </build>

</project>
           

3.2 在resource下建立jdbc.properties檔案，配置資料庫連接配接資訊

driverClasss=com.mysql.jdbc.Driver  
jdbcUrl=jdbc:mysql://localhost:3306/db_ssm
username=root  
password=root  

#定義初始連接配接數  
initialSize=0  
#定義最大連接配接數  
maxActive=20  
#定義最大空閑  
maxIdle=20  
#定義最小空閑  
minIdle=1  
#定義最長等待時間  
maxWait=60000  
           

2.3 在resources下建立log4j配置檔案

log4j.rootLogger=INFO,Console,File  

#控制台日志
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n  

#普通檔案日志
log4j.appender.File=org.apache.log4j.RollingFileAppender  
log4j.appender.File.File=logs/ssm.log  
log4j.appender.File.MaxFileSize=10MB  
#輸出日志，如果換成DEBUG表示輸出DEBUG以上級别日志
log4j.appender.File.Threshold=ALL  
log4j.appender.File.layout=org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n  
           

3.4 配置spring-mybatis.xml

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>
           

3.5 配置springMVC配置檔案

基本的ssm算是搭建起來了，在下一遍部落格中我将用這個架構來具體實作增删改查等操作。并詳細介紹ssm的請求處理流程，以及各配置檔案的具體作用。
