SSM框架搭建-记录

Maven 创建父子工程

首先在Idea新建工程，选择Maven，不用勾选Create from archetype.

填写GroupId和ArtifactId,Version选择默认

创建好后在选择File->Module创建子工程

 此处勾选Create from archetype

填写ArtifactId为boke-web

最后这里选择archetypeCatalog=internal

这个参数的意义是让该 Maven 项目的骨架不要到远程下载而是从本地获取，以提高加载速度。

创建好的工程目录如下：

 

此时没有webapp目录，没有web.xml文件，需要进行配置

然后添加一些文件夹如java、resource等

配置好后目录结构如下：

 

添加如下maven依赖和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、

需要添加相对应的配置文件，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

log4j.properties配置如下：

log4j.rootLogger=DEBUG,Console,File    
#日志输出到控制台    
log4j.appender.Console=org.apache.log4j.ConsoleAppender    
#指定输出到控制台   
log4j.appender.Console.Target=System.out    
#灵活地指定布局模式  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout    
#日志输出格式设置   
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n   
 #日志输出到文件    
log4j.appender.File=org.apache.log4j.RollingFileAppender    
#日志存放位置   
log4j.appender.File.File=E:/IdeaWorspace/log/run.log    
#单个日志文件大小设置   
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

mybatis-config.xml配置如下：

注意：mybatis-config.xml添加了plugins，简单理解为拦截器，既然是拦截器说白了一般都是动态代理来实现对目标方法的拦截，在前后做一些操作。 在mybatis将这种东西，称之为plugin，配置在mybatis-config.xml配置文件中，通过 <plugins></plugins>标签配置。mybatis-config.xml中<plugins>节点中加入通用mapper插件和分页插件

在mybatis中，可以被拦截的目标主要是：

1. StatementHandler;

2. ParameterHandler;

3. ResultSetHandler;

4. Executor;

    </plugins>
</configuration>

srping-mvc.xml的配置

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

配置spring-mybatis.xml如下：

此处spring与mybatis整合采用MapperScannerConfigurer，它将会查找类路径下的映射器并自动将它们创建成MapperFactoryBean
