idea中使用maven整合ssm

布满荆棘的人生 2022-05-10 00:33 201阅读 0赞

**1.首先创建maven项目**

![在这里插入图片描述][70]  
选择新建maven项目并勾选Create from archetype并选择webapp进行项目的构建，然后点击next

![在这里插入图片描述][70 1]  
填写项目相关信息：  
GroupID 是项目组织唯一的标识符，实际对应JAVA的包的结构，是main目录里java的目录结构。  
ArtifactID是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。  
设置好之后点击next

选择maven，可以选择本地的maven或者使用idea自带的maven进行创建。然后点击next。

这里配置项目的名称，直接finish就行。

**2.包结构的设置**  
自己手动创建项目包，创建好后的项目结构如下图所示。

这是我们是不能再Java目录下直接创建Java文件的，我们需要将包的属性改为source。如下图所示。点击左上角的file然后点击project Structs然后点击modules将mian下的Java文件夹标记为source，resources文件夹标记为resource。将test下的Java标记为test，resources标记为resource。

**3.配置文件**

3.1 首先配置pom.xml。由于用maven来管理项目，所以相关依赖我们不必再自己手动导入。而是用pom.xml配置相关jar包。下面是简易的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">

3.2 在resource下新建jdbc.properties文件，配置数据库连接信息

driverClasss=com.mysql.jdbc.Driver  
    jdbcUrl=jdbc:mysql://localhost:3306/db_ssm
    username=root  
    password=root  
    
    #定义初始连接数  
    initialSize=0  
    #定义最大连接数  
    maxActive=20  
    #定义最大空闲  
    maxIdle=20  
    #定义最小空闲  
    minIdle=1  
    #定义最长等待时间  
    maxWait=60000

3.3 在resources下新建log4j配置文件

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  
    
    #普通文件日志
    log4j.appender.File=org.apache.log4j.RollingFileAppender  
    log4j.appender.File.File=logs/ssm.log  
    log4j.appender.File.MaxFileSize=10MB  
    #输出日志，如果换成DEBUG表示输出DEBUG以上级别日志
    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
