<web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

3.编写applicationContext.xml
和web.xml同级，这里的applicationContext.xml被用于加载多个资源文件，名字与web.xml初始化加载的文件相同。
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
">
<import resource="application-mybatis.xml"/>
<import resource="application-spring.xml"/>
<import resource="application-springMVC.xml"/>
beans>

3.2编写application-springMVC.xml
和applicationContext.xml同级。
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4.编写数据源db.properties
该文件放于src目录下。
db_driver=com.mysql.jdbc.Driver
db_url=jdbc:mysql://localhost:3306/db_ssm?useUnicode=true&characterEncoding=UTF-8
db_username=root
db_password=root
附录：
1.log4j配置文件log4j.properties
该文件放于src目录下，文件名必须为log4j.properties，按需更改配置内容。
log4j.rootLogger=debug,stdout,file
### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{YYYY-MM-dd HH:mm:ss.SSS} [%-5p]--[%-40.40c{39}:%3L]--%m%n
### direct log messages to file ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=mylog
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{YYYY-MM-dd HH:mm:ss.SSS} [%-5p]--[%-40.40c{39}:%3L]--%m%n
### set log levels - for more verbose logging change 'info' to 'debug' ###
log4j.rootLogger=DEBUG, stdout
log4j.logger.org.apache=ERROR
log4j.logger.org.apache.ibatis=INFO
log4j.logger.org.springframework=ERROR
log4j.logger.org.mybatis=DEBUG
log4j.logger.org.apache.http=ERROR
log4j.logger.com.netflix=ERROR
2.日期转换器
package com.gjy.converter;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.springframework.core.convert.converter.Converter;
public class DateConverter implements Converter<String, Date> {
@Override
public Date convert(String strDate) {
if ("".equals(strDate) || strDate == null) {
return null;
}
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date date = null;
try {
date = sdf.parse(strDate);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return date;
}
}
3.springMVC拦截器
package com.gjy.interceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
public class MyInterceptor implements HandlerInterceptor {
@Override
public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3)
throws Exception {
// TODO Auto-generated method stub
System.out.println("最后执行，一般用来释放资源。。。");
}
@Override
public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3)
throws Exception {
// TODO Auto-generated method stub
System.out.println("在controller之后执行");
}
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object object) throws Exception {
// TODO Auto-generated method stub
System.out.println("在controller之前执行");
System.out.println(request.getQueryString());
return true;
}
}
