SpringMVC+MyBatis+C3P0连接池详细配置

关于SpringMVC+MyBatis+C3P0连接池结合的框架做了一个配置：

首先导入相关的架包：

其中有些可以删除，像commons-fileupload-1.2.1.jar是做上传用的，我们可以扔掉，还有一些看自己所需吧。

配置web.xml：

 
		CharacterEncodingFilter
		org.springframework.web.filter.CharacterEncodingFilter
		
			encoding
			utf-8
		
		

	
		org.springframework.web.context.ContextLoaderListener
	
    
		contextConfigLocation
		classpath:applicationContext.xml
	
                forceEncoding
                true
                
  CharacterEncodingFilter
  /*
 
  
 
  
 
  
 
  

	
		springMVC
		org.springframework.web.servlet.DispatcherServlet
		  
        contextConfigLocation  
        classpath:springMVC-servlet.xml  
          
		1
	
	
		springMVC
		*.do
	
 
  
在配置Spring文件之前，我们要先配置一下属性文件：jdbc.properties（这里用的oracle数据库）
 
  
 
  
datasource.driverClassName=oracle.jdbc.driver.OracleDriver
datasource.url=jdbc\:oracle\:thin\:@localhost\:1521\:orcl
datasource.username=dglt
datasource.password=12345


c3p0.acquireIncrement=3
c3p0.initialPoolSize=3
c3p0.idleConnectionTestPeriod=60
c3p0.minPoolSize=5
c3p0.maxPoolSize=100
c3p0.maxStatements=100
c3p0.numHelperThreads=10
c3p0.maxIdleTime=60
 
  

 
  
 
  
Spring相关文件配置（applicationContext.xml）：
 
  
1）配置c3p0连接池：
 
  
 
  

        
	        
	            classpath:jdbc.properties
	        
        

    
    
    
        
            ${datasource.driverClassName}
        
        
            ${datasource.url}
        
        
            ${datasource.username}
        
        
            ${datasource.password}
        
         
        
            ${c3p0.acquireIncrement}
        
         
        
            ${c3p0.initialPoolSize}
        
        
            ${c3p0.minPoolSize}
        
        
            ${c3p0.maxPoolSize}
        
         
        
            ${c3p0.maxIdleTime}
        
         
        
            ${c3p0.idleConnectionTestPeriod}
        
         
        
            ${c3p0.maxStatements}
        
         
        
            ${c3p0.numHelperThreads}
        
    
 
   2）创建SqlSessionFactory，同时指定数据源 
  
 
  
 
  
          
	       
	      
 
 
  3）配置模板类 这个是mybatis提供的一个辅助模板，用来获取session 
  
 
  
 
  

	
 
  4）配置事务驱动 
  
 
  
 
  
   
    	
 
 
  5）配置自动扫描（将dao层和services层扫进来即可） 
  
 
  
 
  
 

 
  
 
  配置和前台相关的xml（springMVC-servlet.xml）： 
  
 
  
 
  


 
 
  
    


    
    
    

     
    
        
          
        
    
      
     
 

 
  配置MyBatis sql映射文件（SqlMapConfig.xml）： 
  
 
  
 
  
  
  
       
       	
       		
       		
       	
      		 
       		
       			  
       			  
       		
       		
       		
       		
       			  
       			  
       		
       


  
 
  Mapper配置（相关的sql）： 
  
 
  
 
  
 







 














 




insert into hetong(id,jzmc,hetong)values(#{id},#{jzmc},#{hetong})



  
        SELECT HETONG_SEQ.Nextval  FROM DUAL  
   
	insert into  
	hetong(
	id,
	jzmc,
	hetong,
	qibie_id,
	quyu_id,
	zhenqu_id,
	mianji,
	dizhi,
	yzmc,
	yzdh) 
	values
	(
	#{id,jdbcType=VARCHAR},
	#{jzmc,jdbcType=VARCHAR},
	#{hetong,jdbcType=VARCHAR},
	#{qibie_id,jdbcType=VARCHAR},
	#{quyu_id,jdbcType=VARCHAR},
	#{zhenqu_id,jdbcType=VARCHAR},
	#{mianji,jdbcType=VARCHAR},
	#{dizhi,jdbcType=VARCHAR},
	#{yzmc,jdbcType=VARCHAR},
	#{yzdh,jdbcType=VARCHAR}
	)






select  id, jzmc,hetong,qibie_id,quyu_id,zhenqu_id,mianji,dizhi,yzmc,yzdh from  hetong  where id=#{id}



select  count(*) as count from  hetong




select hetong.id as id,
       hetong.jzmc,
       hetong.hetong,
       a.name as qibiename,
       b.name as quyuname,
       c.name as zhenquname,
       hetong.mianji,
       hetong.dizhi,
       hetong.yzmc,
       hetong.yzdh
  from hetong hetong, paramtertable a, paramtertable b, paramtertable c
 where hetong.qibie_id = a.id
   and hetong.quyu_id = b.id
   and hetong.zhenqu_id = c.id

and jzmc like #{jzmc}


and quyu_id=#{quyu_id}


and yzdh=#{yzdh}

order by id desc

 


delete from hetong where id=#{id111}




delete from hetong where id in

#{item}




	update hetong 
	
		jzmc=#{jzmc},
		hetong=#{hetong},
		qibie_id=#{qibie_id},
		quyu_id=#{quyu_id},
		zhenqu_id=#{zhenqu_id},
		mianji=#{mianji},
		dizhi=#{dizhi},
		yzmc=#{yzmc},
		yzdh=#{yzdh},
	
	where id=#{id}






 
  
 
  
 
  
 大致的相关配置差不多就这些了。
