搭建ssm框架
来源：互联网 发布：武藏点胶机编程 编辑：程序博客网 时间：2024/05/22 10:51
工具：ide:eclipse 插件：maven 架构：ssm架构
springmvc spring.mvc 主要是 ①注解驱动 ②扫contrller所在包 ③视图解析器
spring applicationcontext.xml ①扫service实现类所在包 ②配置数据库连接池 datasource③配置sqlsessionfactorybean④配置mapperscannerconfig
mybatis mybatis.xml ①扫描mapper配置文件，（mybatis.xml中配置可以全部写到applicationcontext.xml中）
tomcat的配置文件web.xml ①扫描springmvc.xml②配置监听器，扫描applicationcontext.xml③配置字符编码过滤器。
src/main/java新建package
contrller包 只写实现类。
service包 写serviceinterface，和实现类。 service包的实现类必须实现serviceinterface
dao包 只写接口interface。
entity包 写和数据库表对应的java类pojo。
mapper包 写和entity对应的配置文件。
src/main/resource包下写配置文件。
框架主要是配置文件，
、
新建一个maven项目war工程：
①在src/main/webapp下新建一个folder web-inf 在web-inf下新建一个web.xml，因为我之前新建了web.xm模版，在下边有
②根据web.xml配置的applicationcontext.xml位置新建一个applicationcontext.xml。
③根据web.xml配置的springmvc配置文件的位置位置新建一个springmvc.xml。
④在src/main/java下新建包，分别为：controller包，service包，dao包，entity包，mapper包，
⑤在entity包下新建和数据库中的表对应的pojo
⑥controller包下新建一个类，类中写具体实现。
⑦在mapper包下写具体的mapper.xml配置文件。mapper.xml和具体的pojo进行对应。
⑧在service包下写接口和service的实现类。
我建议大家可以把这些框架的配置文件做成模版，然后使用的时候直接使用。
首先是web.xml
<?xml version="1.0" encoding="UTF-8"?> <!-- 声明XML的版本 和编码方式 --><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_3_0.xsd"version="3.0"> <!-- --><!--上边是约束 --><display-name>chnsys-work-demo</display-name><!-- XML编辑器显示的名称--><context-param><param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value></context-param><listener> <!-- 这个监听器是log4j的监听器 --><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class></listener><!-- 主要是用来管理日志 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationcontext.xml</param-value></context-param> <filter> <filter-name>characterEncoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncoding</filter-name> <url-pattern>*.do</url-pattern> </filter-mapping><servlet><servlet-name>spring</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:servlet/spring-servlet.xml</param-value></init-param><load-on-startup>0</load-on-startup> <!--load-on-startup和listener一样都是spring和springmvc的配置文件可以在服务器启动功能的时候就启动 --></servlet><servlet-mapping><servlet-name>spring</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>
然后是pom.xml（像这个pom.xml文件就比较大，包含的jar包也比较多）
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

接下来是mapper.xml 一个小的配置
