SSM开发环境的搭建（方式一）

SSM全称：Spring-SpringMVC-MyBatis

1.导包。



2.配置web.xml。

<?xml version="1.0" encoding="UTF-8"?>
<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 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<servlet>
<servlet-name>springweb</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-*.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springweb</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

<filter>
<filter-name>encoding</filter-name>
<filter-class>
.......xxxFilter
</filter-class>
<init-param>
<param-name>contentType</param-name>
<param-value>text/html;charset=utf8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>

3.在src下建立包。



4.进行配置文件。

config.properties是存储mysql信息的。

driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/db_note
username=root
password=root
maxActive=10
maxWait=5000

spring-web.xml 扫描加载controller使用的配置。

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

log4j.properties 配置log4j进行日志信息的打印输出。示例，可不相同。

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file mylog.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c:\mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=info, stdout

5.测试mybatis连接数据库是否成功。

6.开始开发。
