用Maven整合SpringMVC+Spring+Hibernate 框架,
实现简单的插入数据库数据
一、搭建开始前的准备
1、打开MyEclipse新建Maven项目。File>New>Other(或Ctrl+N)>Maven Project;然后我们用default Workspace就行了(注意Location的路径,区分目录名和项目名);然后再Filter中输入webapp,我们选择org.apache.maven.archetypes 下的maven-archetype-webapp;点击下一步,填入Group Id(公司名,一般为com.xxx),Artifact Id(项目名),包名(一般根据公司名和项目名生成),单机Finish就创建完一个Maven的Web项目了。注: 创建出来后有时候会有错(具体是index.jsp)这是因为我们没有在pom.xml中添加servlet的原因,自己加上就OK了。
2、一般创建出来的项目,只有src/main/resources,然后我们加上其他的三项(必须是新建Source Folder!s rc/main/java; src/test/resources; src/test/java ),有时候会提示你该文件夹已经存在,我们稍改一下名,等创建完了后再用F2改回正确的就OK了(例如 s rc/main/java创建失败,我们把java改为javas,最后再改为java即可。 )
最终创建出来的目录如图:
二、搭建
1、我习惯先建立一些package包名( src/main/java) ,例如:xxx.xxx.dao; xxx.xxx.dao.impl; xxx.xxx.model; xxx.xxx.service; xxx.xxx.service.impl; xxx.xxx.controller;具体的包应该放什么,起什么作用,大家可以百度。
2、配置资源文件,也就是所谓的src/main/resources下的文件。
(1.)config.properties
#\u5C5E\u6027\u6587\u4EF6
#Oracle \u7684\u914D\u7F6E
#hibernate.dialect=org.hibernate.dialect.OracleDialect
#driverClassName=oracle.jdbc.driver.OracleDriver
#validationQuery=SELECT 1 FROM DUAL
#jdbc_url=jdbc:oracle:thin:@localhost :1521:orcl
#jdbc_username=
#jdbc_password=
#SQLServer \u7684\u914D\u7F6E
#hibernate.dialect=org.hibernate.dialect.SQLServerDialect
#driverClassName=net.sourceforge.jtds.jdbc.Driver
#validationQuery=SELECT 1
#jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/sy
#jdbc_username=
#jdbc_password=
#Derby \u7684\u914D\u7F6E
#hibernate.dialect=org.hibernate.dialect.DerbyDialect
#driverClassName=org.apache.derby.jdbc.EmbeddedDriver
#validationQuery=SELECT 1
#jdbc_url=jdbc:derby:sy;create=true
#jdbc_username=
#jdbc_password=
#MySQL \u7684\u914D\u7F6E
hibernate.dialect=org.hibernate.dialect.MySQLDialect
driverClassName=com.mysql.jdbc.Driver
validationQuery=SELECT 1
jdbc_url=jdbc:mysql://localhost:3306/sshf?useUnicode=true&characterEncoding=utf-8
jdbc_username=root
jdbc_password=
hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=false
sessionInfoName=sessionInfo
uploadFieldName=filedata
uploadFileMaxSize=20971520
uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,mid
uploadDirectory=attached
注意: ?useUnicode=true&characterEncoding=utf-8
这句话,是UTF8的编码。注释的部分是其他数据库的编写形式。
(2.)log4j.properties
log4j.rootLogger=INFO,A1,R
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.Target=System.out
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=[%c]%m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=sshf.log
log4j.appender.R.MaxFileSize=10MB
log4j.appender.R.Threshold=ALL
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n
注意: sshf.log
就是输出日志文件的文件名
(3.)spring.xml
<?xml version="1.0" encoding="UTF-8"?>
