1、使用IntelliJ IDEA 建立Maven管理的JAVA Web項目html

①新建項目，選擇Maven Modulejava

在本地磁盤用戶的。.m2目錄下生成settings文件：web

Maven工程搭建完畢！！！spring

② 開發步驟：數據庫

自動從本地倉庫下載Jar包：apache

③ 因爲Maven對oracle數據庫的不支持，咱們須要將Oracle裝載到本地倉庫，api

讓Maven使用Oraclesession

一、配置Maven3.3.9 bin到環境變量mybatis

而後能夠經過cmd命令行 mvn -version測試有沒有測試成功！！！架構

二、定位到Oracle安裝目錄的jdbc文件夾

④搭建分層架構---實現添加學生

實體類UserInfo:

package cn.wj.entity;

/**
 * Created by WJ on 2017/1/16.
 */
public class UserInfo {

    private Integer id;
    private String name;
    private Integer age;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }
}

　dao接口：　無需dao實現類，經過代理生成

public interface IUserInfoDao {
    public void add(UserInfo info);

}

　service層：

public interface IUserInfoService {

    public void add(UserInfo info);
}

　service實現類：

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;
    }
}

　控制器類：controller　

public class UserInfoController implements Controller {

    private IUserInfoService service;

    public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {

        String uname=httpServletRequest.getParameter("uname");
        Integer uage=Integer.valueOf(httpServletRequest.getParameter("uage"));

        UserInfo info=new UserInfo();
        info.setName(uname);
        info.setAge(uage);

        service.add(info);

        return new ModelAndView("/welcome.jsp");
    }

    public IUserInfoService getService() {
        return service;
    }

    public void setService(IUserInfoService service) {
        this.service = service;
    }
}

　因爲是整合MyBatis，須要書寫核心配置文件：

小配置：UserInfoDao.xml:　

<?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.wj.dao.IUserInfoDao">
<select id="add" parameterType="UserInfo">
insert into userinfo values(SEQ_Num.nextval,#{name},#{age})
</select>

</mapper>

　MyBatis配置文件：mybatis-config.xml

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

<configuration>
<typeAliases>
<package name="cn.wj.entity"/>
</typeAliases>


<mappers>

   <package name="cn.wj.dao"/>

</mappers>
</configuration>

　applicationContext.xml：進行植入dao、service、controller、事務管理器、數據源、sessionFactory　

index.jsp頁面：

<body>
<form action="${pageContext.request.contextPath }/userAction.do" method="post">
    用戶名：<input name="uname"/> <br/><br/>
    年齡:<input name="uage"/><br/><br/>
    <input type="submit" value="add"/>
</form>
</body>

　Web.xml:進行配置中央調度器　

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
  <!-- 1.針對Spring配置：讀取配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!-- 註冊ServletContext監聽器，建立容器對象，而且將ApplicationContext對象放到Application域中 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- 針對SpringMVC的配置：：：：：：中央調度器：本質上一個serlvet            配置的關於SpringmVC組件 -->
  <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>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

  <!-- 解決亂碼的過濾器 -->
  <filter>
    <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

　　實現效果：

注：若出現此類異常--org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)
