ssm框架基础配置

s-s-m整合(spring springmvc mabatis) 参考

1.导入所需的jar包
2.配置web.xml文件
  2.1   spring 的监听
  2.2   springmvc前端控制器
  2.3   spring 解决中文乱码的过滤器
  等
3.配置三大框架的配置文件
  3.1 applicationContext.xml  (spring)
  3.2 spring-servlet.xml    (springmvc)
  3.3 mybatis-config.xml (mybatis)


4. jdbc.properties 配置文件    这里数据源链接使用的c3p0

web.xml的基本配置
注意了:配置文件一定要和web.xml中的配置名字一样

 
       contextConfigLocation
       classpath:applicationContext.xml
 

 
    org.springframework.web.context.ContextLoaderListener
 
 
 
    spring
    org.springframework.web.servlet.DispatcherServlet
   
        contextConfigLocation
        classpath:spring-servlet.xml
   
    1
 
 
    spring
    /
 
 
   
        characterEncodingFilter 
        org.springframework.web.filter.CharacterEncodingFilter 
         
            encoding 
            UTF-8 
         
         
            forceEncoding 
            true 
         
     
     
        characterEncodingFilter 
        /* 
   

以下为三打框架的配置文件参考

4. jdbc.properties 配置文件（可以直接写在spring的配置文件中）
datasource.driverClassName=com.mysql.jdbc.Driver
datasource.url=jdbc:mysql://192.168.1.1:3306/shoppingdb
datasource.username=root
datasource.password=123456
c3p0.acquireIncrement=3
c3p0.initialPoolSize=3
c3p0.idleConnectionTestPeriod=60
c3p0.minPoolSize=5
c3p0.maxPoolSize=100
c3p0.maxStatements=100
c3p0.numHelperThreads=10
c3p0.maxIdleTime=60
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
mybatis 貌似是没有级联操作
这里分享个技巧
jdbc.properties中的url地址最后加上allowMultiQueries=true
url=jdbc:mysql://192.168.1.1:3306/liubao2?useUnicode=true&characterencoding=utf8&allowMultiQueries=true

让mysql驱动默认开启批量操作
然后就可以这样写了
   
        delete from photos where xid=#{id};
        delete from photoalbum where xid=#{id}
   
这样就可以同时执行两条sql语句了
