SSM框架搭建-記錄

Maven 創建父子工程

首先在Idea新建工程，選擇Maven，不用勾選Create from archetype.

填寫GroupId和ArtifactId,Version選擇默認

創建好後在選擇File->Module創建子工程

 此處勾選Create from archetype

填寫ArtifactId爲boke-web

最後這裏選擇archetypeCatalog=internal

這個參數的意義是讓該 Maven 項目的骨架不要到遠程下載而是從本地獲取，以提高加載速度。

創建好的工程目錄如下：

 

此時沒有webapp目錄，沒有web.xml文件，需要進行配置

然後添加一些文件夾如java、resource等

配置好後目錄結構如下：

 

添加如下maven依賴和properties：

<packaging>war</packaging>
<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.7</maven.compiler.source>

添加配置文件、

需要添加相對應的配置文件，有jdbc.properties、log4j.properties、mybatis-config.xml、spring-mybatis.xml、srping-mvc.xml

jdbc.properties配置如下：

driverClasss=com.mysql.jdbc.Driver    
jdbcUrl=jdbc:mysql://localhost:3306/boke?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull
username=root
password=root    
#定義初始連接數    
initialSize=0    
#定義最大連接數    
maxActive=20    
#定義最大空閒
maxIdle=20    
#定義最小空閒    
minIdle=1    
#定義最長等待時間    
maxWait=60000

log4j.properties配置如下：

log4j.rootLogger=DEBUG,Console,File    
#日誌輸出到控制檯    
log4j.appender.Console=org.apache.log4j.ConsoleAppender    
#指定輸出到控制檯   
log4j.appender.Console.Target=System.out    
#靈活地指定佈局模式  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout    
#日誌輸出格式設置   
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n   
 #日誌輸出到文件    
log4j.appender.File=org.apache.log4j.RollingFileAppender    
#日誌存放位置   
log4j.appender.File.File=E:/IdeaWorspace/log/run.log    
#單個日誌文件大小設置   
log4j.appender.File.MaxFileSize=10MB   
#輸出日誌，如果換成DEBUG表示輸出DEBUG以上級別日誌   
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

mybatis-config.xml配置如下：

注意：mybatis-config.xml添加了plugins，簡單理解爲攔截器，既然是攔截器說白了一般都是動態代理來實現對目標方法的攔截，在前後做一些操作。 在mybatis將這種東西，稱之爲plugin，配置在mybatis-config.xml配置文件中，通過 <plugins></plugins>標籤配置。mybatis-config.xml中<plugins>節點中加入通用mapper插件和分頁插件

在mybatis中，可以被攔截的目標主要是：

1. StatementHandler;

2. ParameterHandler;

3. ResultSetHandler;

4. Executor;

srping-mvc.xml的配置

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

配置spring-mybatis.xml如下：
