宣告：本文純為個人筆記整理，如有不妥之處還望及時指出，歡迎轉載！

只為解決操作問題，可以從第二幅圖往後看！

一、做不出詳細的概念敘述和文字設計，本文主要以實戰步驟為主，少量解釋為輔助，下面請大家牢記兩幅圖：

截圖來自張開濤部落格

      典型的jsp(java server page)是一種伺服器執行的元件，執行在標準HTML頁面的java技術，最終還是被編譯成伺服器可以識別的servlet程式碼，生成.class檔案，相比Servlet開發簡潔、方便，缺點是檢視顯示、業務控制比較複雜，而且把對後端操作放在jsp頁面很不安全；
      故產生了Jsp+JavaBean開發，使用<jsp:usebean>標籤，自動將請求封裝為javabean元件，可以認為是為了增強jsp開發；這也是單一的開發思路，即下圖所示，這種模型同樣是沒有本子上解決問題，大量的業務處理依然在jsp頁面中，而bean負責的只有引數的請求處理；所以出現了我們的MVC模型；
jsp+bean模型

MVC模型

在JvavEE的開發中，可以認為下圖就是我們的web mvc模型

控制器用servlet、模型用JavaBean、檢視採用Jsp

二、下面開始步入正題；

進行springmvc開發，寫業務邏輯之前，首先要做到：

1.開發環境（jdk+IDE+maven+mysql）

2.配置環境（web.xml、pom.xml、application.xml、springmvc.xml、mybatis.xml）

3.定義domian、生成dao、mapper

按照上述步驟進行開發，便於在後期調錯，另外可以個那好的梳理業務邏輯，本文只介紹，檔案配置到連線上資料庫。

三、SpringMvc開發用到的通用配置檔案

1.pom.xml這裡貼上一個詳細的pom檔案，包含各種依賴和maven常用的幾個外掛

2.web.xml 需要注意其中兩個配置檔案一個是application.xml ：主要配置dataSource、dao、service等跟持久化相近的非webBean

一個是springmvc.xml：配置controller、handlerResolver檢視解析器等web層元件

<?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" id="WebApp_ID" version="3.0">
<display-name>springmvc</display-name>
<welcome-file-list>
<welcome-file>/views/login.jsp</welcome-file>
</welcome-file-list>
<!-- 處理字符集編碼 -->

</init-param>
</filter>
<filter-mapping>

<!-- 配置springmvc核心過濾器 -->

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

</web-app>

3.application.xml由於我主要用的註解驅動開發，所以這個配置檔案沒有相關的dao、servic的bean配置、我將mybatis的配置單獨寫在Mybatis.xml檔案裡，但是不要忘記引入到這裡。如果只有資料庫配置的話，也可以直接寫進來（不建議）

4.Mybatis.xml 注意 db.properties 檔案中的內容username、password注意不要配置的太通用有可能會和本機的配置衝突

db.properties檔案中的內容

driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/studentmanager?useUnicode=true&characterEncoding=UTF-8
jdbcUserName=root
jdbcPassword=root

Mybatis.xml

5.SpringMVC.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<property name="exceptionMappings">
<props>
<prop key="java.lang.ArrayIndexOutOfBoundsException">error</prop>
</props>
</property>
</bean>


</beans>

6.dao和mapper.xml 我這裡只粘了一個dao和mapper的樣例

特別注意：

1.dao引數型別和Mapper的引數型別嚴格對稱

2.mapper中的resultMap配置，前面是資料庫欄位名、後面是對應物件名，要嚴格一致

3.不要在Mybtais.xml中引入dao和mapper的位置

package com.cmos.dao;
import com.cmos.domain.District;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface DistrictDao {


int deleteByPrimaryKey(Integer disId);

int insert(District record);

int updateByExample(@Param("example") District example);

List<District> selectAll();


}




Mapper.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="com.cmos.dao.DistrictDao">
<resultMap id="BaseResultMap" type="com.cmos.domain.District">
<id column="dis_id" jdbcType="INTEGER" property="disId" />
<result column="dis_name" jdbcType="VARCHAR" property="disName" />
</resultMap>

<select id="selectAll"resultMap="BaseResultMap">
select dis_id,dis_name from district
</select>

<delete id="deleteByPrimaryKey" parameterType="java.lang.Integer">
delete from district
where dis_id = #{disId,jdbcType=INTEGER}
</delete>

<insert id="insert" parameterType="com.cmos.domain.District">
insert into district (dis_id, dis_name)
values (#{disId,jdbcType=INTEGER}, #{disName,jdbcType=VARCHAR})
</insert>

<update id="updateByExample" parameterType="com.cmos.domain.District">
update district
set dis_name = #{example.disName,jdbcType=VARCHAR}
where dis_id = #{example.disId,jdbcType=INTEGER}
</update>
</mapper>
