    1. 前言

    近期在学习java,掌握ssm的整合是必不可少的技能,自学的我,在网络上寻找了许多参考资料,才得以整合成功一个项目。原谅我太笨。为了避免其他人少走弯路,将自己的整合过程记录一下,分析给其他同学。我这么笨都可以,你自然没问题啦。

    2. 参考

    本文章所演示的示例,代码,均来源与网络。其中主要参考了: SSM框架——详细整合教程(Spring+SpringMVC+MyBatis)其实本文就是对该文章的一个更新和补充。因为原文写于 2014年,存在一些小错误。感谢原作者的无私奉献。

    3. 目标群体

    本人适合已经了解一些spring springmvc mybatis 基础知识的java开发者来阅读。使用Mac和idea工具最佳。

    4. 环境说明

    • 开发工具:IntelliJ IDEA 2017.2.1
    • 系统: Mac OS X 10.12.5
    • java 版本: 1.8.0_131

    5. 整合步骤

    1). 建立project

    project在idea里可以理解为工作空间,而非项目。其实module才是真正的项目。

    选择emtpy project 命名为htt

    2). 建立module

    设置为自动载入。

    3). 编写pom.xml文件

    加载依赖的jar包。如果是第一次执行可能会耗时较。

    4).整合spring与mybatis

    • jdbc配置
    driver=com.mysql.jdbc.Driver
    url=jdbc:mysql://127.0.0.1:3306/ssmdemo
    username=root
    password=123456
    #定义初始连接数
    initialSize=0
    #定义最大连接数
    maxActive=20
    #定义最大空闲
    maxIdle=20
    #定义最小空闲
    minIdle=1
    #定义最长等待时间
    maxWait=60000

    • spring-mybatis配置
    <?xml version="1.0" encoding="UTF-8"?>

    • log4j配置
    #定义LOG输出级别
    log4j.rootLogger=INFO,Console,File
    #定义日志输出目的地为控制台
    log4j.appender.Console=org.apache.log4j.ConsoleAppender
    log4j.appender.Console.Target=System.out
    #可以灵活地指定日志输出格式,下面一行是指定具体的格式

    • 测试代码
      • 准备数据库和表
    DROP TABLE IF EXISTS `user_t`;
    
    CREATE TABLE `user_t` (
      `id` int(11) NOT NULL AUTO_INCREMENT,
      `user_name` varchar(40) NOT NULL,
      `password` varchar(255) NOT NULL,
      `age` int(4) NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
    
    /*Data for the table `user_t` */
    
    insert  into `user_t`(`id`,`user_name`,`password`,`age`) values (1,'测试','sfasgfaf',24);
    
    image.png
    • 编写dao maper service serviceimpl
    package cn.wuwenfu.ssmdemo.dao;
    
    
    import cn.wuwenfu.ssmdemo.pojo.User;
    
    public interface IUserDao {
        int deleteByPrimaryKey(Integer id);
    
        int insert(User record);
    
        int insertSelective(User record);
    
        User selectByPrimaryKey(Integer id);
    
        int updateByPrimaryKeySelective(User record);
    
        int updateByPrimaryKey(User record);
    }
    

    sql映射xml

    • 编写测试类。

    • 配置文件,运行测试。注意选择的是appication

    4). 整合spring-mvc

    • 先创建web目录。

    5). 最终的测试

    • 编写视图
    <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
    <head>
        <title>测试</title>
    </head>
    
    <body>
    ${user.userName}
    </body>
    </html>
    
    image.png
    • 编写控制器
    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";
        }
    }
    
    
    image.png
    • 配置运行。这里选择的tomcat server
    image.png image.png image.png
    • 修改module的配置。选择 artifacts
      选中module 点击file 下拉菜单中选择 project structure
      使用快捷键。** command + ; **
    image.png

    检查jar包被放入

    6. 原文章错误的地方(本攻略均已修正)

    • 原作者的整合是基于eclipse,而我使用的idea 。工具对classpath的读取不同。解决方法是 pom.xml需要设定如下配置。(此坑让我好惨。耗费1个下午)
    <resources>
                <resource>
                    <!--   描述存放资源的目录,该路径相对POM路径-->
                    <directory>src/main/java</directory>
                    <includes>
                        <include>**/*.xml</include>
                    </includes>
                </resource>
            </resources>
    
    • UserServiceImpl的getUserById方法上面的override注解必须删掉
    • jdbc.properties里面每行都有2个空格,必须删掉
    • 包名错误。较多,不一一罗列。

    7.截图与项目源码下载。

    csdn太慢了。只能丢云盘了。骗点积分的希望落空。

    由于带了截图,压缩包有60M.
