快速搭建SSM框架
因为最近有很多朋友问我自己的项目搭建的不够完善，并且经常出现一些小问题，那么今天我又整理了一下文档教大家如何快速搭建SSM框架我是用 eclipse搭建的，如果想用idear的话我过段时间再出一个
第一步:创建web项目
第二步：使用小黑鸟工具生成实体类，mapper接口，以及mapper.xml 不需要接口实现类（需要装插件）
第三步：创建service接口，创建service接口实现类，在类上添加@Service(需要提前引入SSM所需lib架包)
然后：调用***mapper dao 并且需要添加@注解共有两种 1：@Autowried 2:@Resource 一种按类型一种按名称
第四步：创建controller 类名上添加@Controller注解 声明这个是个控制器可以根据需求加@RequestMapping
第五步:添加配置文件 applicationContext database.propert mybatis-config springmvc-servlet
给大家附上我的配置文件，可能每个人和每个人的都不一样仅供参考哦
applicationContext.xml内容

<property name="maxUploadSize" value="5000000"/>
<property name="defaultEncoding" value="UTF-8"/>
</bean>
</beans>
第六步：配置完成后在web-inf 下创建一个jsp文件夹 里面放我们的jsp页面
配置web.xml 告诉tomcat我们先扫描那个再扫描哪个 编码集什么的
第七部:web.xml内容
<?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_3_0.xsd" version="3.0">
<display-name>TestS</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param> <filter>
<filter-name>encodingFilter</filter-name>
<filter-class>
org.springframework.web.filter.CharacterEncodingFilter
</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</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:springmvc-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>
然后 taomcat debug运行 然后 ping路径 localhost:端口/项目名/哪个控制器的/那个方法。buling~页面出来了 也就是配置成功了
可以试试看
