快速搭建ssm框架

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

mybatis-config.xmlneirong

springmvc-servlet.xml的内容

    </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
