SSM框架——详细整合教程(Spring+SpringMVC+MyBatis)

无异于、基本概念

     使用SSM(spring、SpringMVC和Mybatis)

1.1、Spring

     
  Spring是一个开源框架,Spring是叫2003 年兴起的一个轻量级的Java 开发框架,由Rod Johnson 在那个著作Expert One-On-One J2EE Development and Design中论述的片段观点以及原型衍生而来。它是以缓解企业应用开发之复杂性使创立的。Spring使用基本的JavaBean来好以前只是恐是因为EJB完成的工作。然而,Spring的用处不仅限于服务器端的开支。从简单性、可测试性和松耦合的角度而言,任何Java应用都得以自Spring中受益。 简单的话,Spring是一个轻量级的决定反转(IoC)和面向切面(AOP)的器皿框架。

1.2、SpringMVC

    Spring MVC属于SpringFrameWork的继承产品,已经融合在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色,这种分离被她更易开展定制。

 1.3、MyBatis

   MyBatis 本是apache的一个开源项目iBatis, 2010年之类别由于apache software foundation 迁移至了google code,并且改名为MyBatis 。MyBatis是一个基于Java的持久层框架。iBATIS提供的持久层框架包括SQL Maps和Data Access Objects(DAO)MyBatis 消除了几有的JDBC代码和参数的手工安装和结果集的摸。MyBatis 使用简便的 XML或注解用于配置与原始映射,将接口及 Java 的POJOs(Plain Old Java Objects,普通的 Java对象)映射成数据库遭逢之笔录。

 (一)配置实体

  

public class UserInfo {
       private Integer userid;//用户的id
    private Integer uage;//用户年龄
    private String uname;//用户姓名
    public Integer getUage() {
        return uage;
    }
    public void setUage(Integer uage) {
        this.uage = uage;
    }
    public String getUname() {
        return uname;
    }
    public void setUname(String uname) {
        this.uname = uname;
    }
    public Integer getUserid() {
        return userid;
    }
    public void setUserid(Integer userid) {
        this.userid = userid;
    }



}

 

(二)配置实体的有些布置(Mybatis的布置)

  

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="cn.yxj.dao.IUserInfoDAO">
    <select id="add" parameterType="cn.yxj.entity.UserInfo">
    <!-- <select id="add" parameterType="UserInfo"> 需要别名在mybatis-config.xml-->
                                <!-- 数据库创建表的时候uid和id是关键字 -->
                    <!-- 添加值的顺序要和数据库一样 -->
        insert into userinfo values(#{uname},#{uage},SEQ_SSM.nextval)
    </select>
</mapper>

 

 (三)创建dao接口

//不需要dao的实现类,通过代理生成
public interface IUserInfoDAO {
//添加用户数据
 public void add(UserInfo info);

}

 注意点:不需要dao的兑现类似,通过代理生成

(四)创建service

  ServiceDao接口

 

public interface IUserInfoService {
    //添加用户
    public void add(UserInfo info);
}

 

    ServiceDaoImpl实现

public class UserInfoServiceImpl implements IUserInfoService {

    private IUserInfoDAO dao;

    public void add(UserInfo info) {
        dao.add(info);
    }
    public IUserInfoDAO getDao() {
        return dao;
    }
    public void setDao(IUserInfoDAO dao) {
        this.dao = dao;
    }

}

 

(五)配置Controller

public class UserInfoController implements Controller{

    private IUserInfoService service;
    public ModelAndView handleRequest(HttpServletRequest request,
            HttpServletResponse response) throws Exception {
        String uname=request.getParameter("uname");
        Integer uage=Integer.valueOf(request.getParameter("uage"));

        UserInfo info=new UserInfo();
        info.setUage(uage);
        info.setUname(uname);

        service.add(info);

        return new ModelAndView("/welcome.jsp");
    }
    public IUserInfoService getService() {
        return service;
    }
    public void setService(IUserInfoService service) {
        this.service = service;
    }
}

 

 

 (六)配置application.xml

     <mappers>
        <mapper resource="cn/yxj/entity/IUserInfoDAO.xml" />
    </mappers>
</configuration>

 

(九)配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

     <servlet>
       <servlet-name>springmvc</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
       <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
       </init-param>
       <!-- 1表示正常初始化配置文件 init-param    0、-1相当于没有设置 -->
       <load-on-startup>1</load-on-startup>
     </servlet>
     <!-- 映射文件 -->

         <filter-name>CharacterEncodingFilter</filter-name>
         <url-pattern>/*</url-pattern>
     </filter-mapping>



  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

 

 (十)配置页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    <style type="text/css">
       form{
         margin:0px auto;
         border:1px solid red;
         width:500px;
         padding:20px;
       }
    </style>
    <title></title>
  </head>

  <body>
    <h1>SSM整合</h1>
    <form action="${pageContext.request.contextPath }/userAction.do" method="post">
            用户名:<input name="uname"/> <br/>
            用户年龄<input name="uage"/><br/>
       <input type="submit" value="save"/>
    </form>
  </body>
</html>

        可以运作了,但是数据库要发UserInfo这个表。
