idea創建ssm框架步驟

打開idea 編輯器

File》new 》project 選擇Maven 右邊勾選Create from archctype   然后下拉選擇org.apache.maven.archetypes:maven-archetype-webapp

如下圖所示：

 

 

Next》

GroupId : 自己填寫代表唯一id，com.test

ArtifactId :項目名稱 test_ssm

Version:1.0-SNAPSHOT 默認就行。如下圖所示：

 

 

Next》

如圖所示：不做任何操作就行

 

 

Nest》不做任何操作，繼續next

 

 

至此 finish 即可。

選擇 New Window 重新打開一個idea

 

 

點擊完成后如下圖：項目結構是

test_ssm

  .idea

  Src

  Pom.xml

  Test_ssm.iml

External Libraries

 

 

點擊src

  Main

     Resources

     Webapp

--WEB-INF (web.xml)

 Index.jsp

少一個 java的文件夾，這時候自己新建一個java文件夾在main下。具體操作為：New》Directory

 

 

 

給java文件夾里創建層級文件夾》com.mvc.modules.controller 自己隨意起名字。大概是這樣的層級

然后就是xml的配置了。

在 resources 下需要這幾個配置文件：

1.Mappings 文件夾先新建一個，空的就行。

2.jdbc.properties

3.log4j.properties

4.spring-mvc.xml

5.spring-mybatis.xml

 

具體配置內容如下：

v Jdbc.properties

 

driver =com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/tsestTable?useUnicode=true&characterEncoding=utf8
username=root
password=root
#定義初始連接數
initialSize=0
#定義最大連接數
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

 

 

v Log4j.prpoerties

#定義LOG輸出級別
log4j.rootLogger=INFO,Console,File
#定義日志輸出目的地為控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以靈活地指定日志輸出格式，下面一行是指定具體的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到達指定尺寸的時候產生一個新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定輸出目錄
log4j.appender.File.File = logs/ssm.log
#定義文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 輸出所以日志，如果換成DEBUG表示輸出DEBUG以上級別日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

 

v Spring-mvc.xml

點擊右下角 Enable Auto-Import更新下載jar包。

 

 

附錄：這些都是先有maven的情況下配置的。默認是c盤下的.m2里面的倉庫。自己也可以配置自己的。不再贅述。

大功告成。

配置tomcat：

進入 Edit Configurations

進入默認tomcat service 選擇local 選擇tomcat安裝路徑

進入默認tomcat service 選擇local 選擇tomcat安裝路徑

點擊 + ，選擇 Tomcat 服務器，如果是本地Tomcat 選擇 Local

Tomcat Server -> Unnamed ->自定名稱 ,選擇Tomcat安裝路徑

添加war 注:idea自動打包

war:將WEB工程以包的形式上傳到服務器 

war exploded:將WEB工程以當前文件夾的位置關系上傳到服務器

建議本地tomcat使用war exploded,上傳到服務器使用war

親測有效的。

 

 

最終效果：http://localhost:8080/

1.mvn mybatis-generator:generate


2.如果是在intellij 環境，直接鼠標點擊即可

 

 

刷新工程目錄，即可看到生成的文件。
