更新時(shí)間 ：2017-09-15 15:26:23 增加github地址

1. 前言

近期在學(xué)習(xí)java,掌握ssm的整合是必不可少的技能，自學(xué)的我，在網(wǎng)絡(luò)上尋找了許多參考資料,才得以整合成功一個(gè)項(xiàng)目。原諒我太笨。為了避免其他人少走彎路,將自己的整合過(guò)程記錄一下,分析給其他同學(xué)。我這么笨都可以，你自然沒(méi)問(wèn)題啦。

2. 參考

本文章所演示的示例，代碼，均來(lái)源與網(wǎng)絡(luò)。其中主要參考了: SSM框架——詳細(xì)整合教程（Spring+SpringMVC+MyBatis）其實(shí)本文就是對(duì)該文章的一個(gè)更新和補(bǔ)充。因?yàn)樵膶?xiě)于 2014年,存在一些小錯(cuò)誤。感謝原作者的無(wú)私奉獻(xiàn)。

3. 目標(biāo)群體

本人適合已經(jīng)了解一些spring springmvc mybatis 基礎(chǔ)知識(shí)的java開(kāi)發(fā)者來(lái)閱讀。使用Mac和idea工具最佳。

4. 環(huán)境說(shuō)明

• 開(kāi)發(fā)工具:IntelliJ IDEA 2017.2.1
• 系統(tǒng): Mac OS X 10.12.5
• java 版本: 1.8.0_131

5. 整合步驟

1). 建立project

project在idea里可以理解為工作空間,而非項(xiàng)目。其實(shí)module才是真正的項(xiàng)目。

選擇emtpy project

命名為htt

2). 建立module

設(shè)置為自動(dòng)載入。

3). 編寫(xiě)pom.xml文件

加載依賴(lài)的jar包。如果是第一次執(zhí)行可能會(huì)耗時(shí)較。

4).整合spring與mybatis

• jdbc配置

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/ssmdemo
username=root
password=123456
#定義初始連接數(shù)
initialSize=0
#定義最大連接數(shù)
maxActive=20
#定義最大空閑
maxIdle=20
#定義最小空閑
minIdle=1
#定義最長(zhǎng)等待時(shí)間
maxWait=60000

5). 最終的測(cè)試

• 編寫(xiě)視圖

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <title>測(cè)試</title>
</head>

<body>
${user.userName}
</body>
</html>

image.png

• 編寫(xiě)控制器

package cn.wuwenfu.ssmdemo.controller;

import cn.wuwenfu.ssmdemo.pojo.User;
import cn.wuwenfu.ssmdemo.service.IUserService;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;


@Controller
@RequestMapping("/user")
public class UserController {
    @Resource
    private IUserService userService;

    @RequestMapping("/showUser")
    public String toIndex(HttpServletRequest request,Model model){
        int userId = Integer.parseInt(request.getParameter("id"));
        User user = this.userService.getUserById(userId);
        model.addAttribute("user", user);
        return "showUser";
    }
}

• 配置運(yùn)行。這里選擇的tomcat server

• 修改module的配置。選擇 artifacts
  選中module 點(diǎn)擊file 下拉菜單中選擇 project structure
  使用快捷鍵。** command + ; **

image.png

檢查jar包被放入

• 最終的運(yùn)行結(jié)果。
  訪(fǎng)問(wèn)地址 http://localhost:8080/ssmdemo/user/showUser?id=1

6. 原文章錯(cuò)誤的地方(本攻略均已修正)

• 原作者的整合是基于eclipse，而我使用的idea 。工具對(duì)classpath的讀取不同。解決方法是 pom.xml需要設(shè)定如下配置。(此坑讓我好慘。耗費(fèi)1個(gè)下午)

<resources>
            <resource>
                <!--   描述存放資源的目錄，該路徑相對(duì)POM路徑-->
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>

• UserServiceImpl的getUserById方法上面的override注解必須刪掉
• jdbc.properties里面每行都有2個(gè)空格，必須刪掉
• 包名錯(cuò)誤。較多，不一一羅列。

7.截圖與項(xiàng)目源碼下載。

csdn太慢了。只能丟云盤(pán)了。騙點(diǎn)積分的希望落空。

由于帶了截圖，壓縮包有60M.
