快速搭建SSM新手易上手（简易版，适合新手入门，非常详细）

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

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>TestSdisplay-name>
  <context-param>
  <param-name>contextConfigLocationparam-name>
  <param-value>classpath:applicationContext.xmlparam-value>
  context-param>
  
  <filter>
    <filter-name>encodingFilterfilter-name>
    <filter-class>
          org.springframework.web.filter.CharacterEncodingFilter
      filter-class>
    <init-param>
      <param-name>encodingparam-name>
      <param-value>UTF-8param-value>
    init-param>
    <init-param>
      <param-name>forceEncodingparam-name>
      <param-value>trueparam-value>
    init-param>
  filter>
  <filter-mapping>
    <filter-name>encodingFilterfilter-name>
    <url-pattern>/*url-pattern>
  filter-mapping>
  
   <servlet>
    <servlet-name>springservlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
    <init-param>
      <param-name>contextConfigLocationparam-name>
      <param-value>classpath:springmvc-servlet.xmlparam-value>
    init-param>
    <load-on-startup>1load-on-startup>
  servlet>
  <servlet-mapping>
    <servlet-name>springservlet-name>
    <url-pattern>/url-pattern>
  servlet-mapping>
  
  <listener>
     <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
  listener>

  <welcome-file-list>
    <welcome-file>index.htmlwelcome-file>
    <welcome-file>index.htmwelcome-file>
    <welcome-file>index.jspwelcome-file>
    <welcome-file>default.htmlwelcome-file>
    <welcome-file>default.htmwelcome-file>
    <welcome-file>default.jspwelcome-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
