简单的SSM框架搭建教程

简单的ssm框架的搭建和配置文件

• ssm框架里边的配置：

• 1.src路径下直接存放数据库和log4j的properties文件

• 2.src路径下建个config包，分别放置ssm的xml文件

• 3.修改web-inf路径下的web.xml

• 4.注意放置配置文件的路径问题

---

1.src路径下的jdbc.propreties和log4j.properties

log4j.properties

log4j.properties里边的代码，例如：

# global logging configuration
log4j.rootlogger=debug, stdout
# console output...
log4j.appender.stdout=org.apache.log4j.consoleappender
log4j.appender.stdout.layout=org.apache.log4j.patternlayout
log4j.appender.stdout.layout.conversionpattern=%5p [%t] - %m%n

jdbc.properties

jdbc.properties里边的代码，例如：

1  # global logging configuration
2 jdbc.driverclassname=com.mysql.jdbc.driver
3 jdbc.url=jdbc:mysql:///ssm_my?useunicode=true&characterencoding=utf8
4 jdbc.username=root
5 jdbc.password=root

2.src路径下建个config包，分别放置ssm的xml文件

applicationcontext.xml
