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

properties的位置

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&amp;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

ssm各自的xml文件

applicationContext.xml

spring框架里边applicationContext.xml配置文件的代码，例如：

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