eclipse创建maven的ssm项目

       自己接触ssm框架有一段时间了，从最早的接触新版ITOO项目的（SSM/H+Dobbu zk），再到自己近期来学习到的《淘淘商城》一个ssm框架的电商项目。用过，但是还真的没有自己搭建过，一直都是用别人搭建好的。所以，从网上找了一些材料，结合自己来解决过程中的一些问题，使自己对ssm框架理解更加深了，不为分享，只是总结一下，下次有机会再搭建的时候，直接看自己的博客，省得找了！

一、准备环境：

       maven：apache-maven-3.2.3

       jdk：jdk1.8.0_25

       tomcat：tomcat-6.0.37

       MySQL：阿里云centos7 搭建的mysql

二、配置Maven、jdk

     1、Window——>Preferences——>Maven——>设置自己的Settings

     2、Window——>Preferences——>Java——>Installed JREs——>Add

              

     配置好maven之后，就可以在本地设置好的地方看到对应的Maven文件了，还有包含resp文件夹

三、新建Maven项目：

     1、右击——>New（或者是File——>New）——>other——>Maven——>Maven Project——>Next

           

           

2、这时候，我们就成功创建出一个Maven项目了，项目结构如下图：

          

       到这里，我们的Maven项目就建好了，接下来，我们来整合搭建SSM（spring MVC + Spring + Mybatis）

首先我们来配置一些整合框架所必须要的jar包，也就是来配置我们的pom文件，然后直接alt+f5，保存后，就会自动下载，存放在之前配置好的本地maven仓库中。

pox.xml配置依赖的内容：

2、在src/main/resources下添加配置文件：spring-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>

    </bean>

</beans>

配置数据库连接池：jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://**.**.**.**:3306/db_zsl
jdbc.username=root
jdbc.password=123456

#u5B9Au4E49u6700u957Fu7B49u5F85u65F6u95F4  jdbc.
jdbc.maxWait=60000

配置日志：log4j.properties

log4j.rootLogger=INFO,Console,File

接下来，我们来整合spring mvc：spring-mvc.xml:

<?xml version="1.0" encoding="UTF-8"?>

    <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->

    <bean id="mappingJacksonHttpMessageConverter"

</beans>

修改web.xml

到这里，我们的ssm框架就完成了，下面，我们来个实现：

在src/main/java下分别添加我们的dao包，service包，还有controller包.包里面添加相应的类，效果图如下：

UserController.java:

package com.cn.hnust.controller;

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

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.cn.hnust.pojo.User;
import com.cn.hnust.service.IUserService;

@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";
        }
}

IUserDao.java:

package com.cn.hnust.dao;

import com.cn.hnust.pojo.User;

public interface IUserDao {

    public User selectByPrimaryKey(int userId) ;
}

User.java:

package com.cn.hnust.pojo;

public class User {
    private Integer id;

    private String userName;

    private String password;

    private Integer age;

    public Integer getId() {
        return id;
    }

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

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName == null ? null : userName.trim();
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password == null ? null : password.trim();
    }

    public Integer getAge() {
        return age;
    }

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

UserMapper.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.cn.hnust.dao.IUserDao">
  <resultMap id="BaseResultMap" type="com.cn.hnust.pojo.User" >
    <id column="id" property="id" jdbcType="INTEGER" />
    <result column="user_name" property="userName" jdbcType="VARCHAR" />
    <result column="password" property="password" jdbcType="VARCHAR" />
    <result column="age" property="age" jdbcType="INTEGER" />
  </resultMap>
  <sql id="Base_Column_List" >
    id, user_name, password, age
  </sql>
  <select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.Integer" >
    select
    <include refid="Base_Column_List" />
    from user_t
    where id = #{id,jdbcType=INTEGER}
  </select>
</mapper>

IUserService.java:

package com.cn.hnust.service;

import com.cn.hnust.pojo.User;

public interface IUserService {
    public User getUserById(int userId);
}

UserServiceImpl.java:

package com.cn.hnust.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.cn.hnust.dao.IUserDao;
import com.cn.hnust.pojo.User;
import com.cn.hnust.service.IUserService;

@Service("userService")
public class UserServiceImpl implements IUserService {
    @Resource
    private IUserDao userDao;

    public User getUserById(int userId) {
        return this.userDao.selectByPrimaryKey(userId);
    }
}

接下来就是我们的静态页面了jsp文件了，在WEB-INF文件夹下新建jsp文件夹，添加userinfo.jsp

showUser.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<!-- localhost:8080/storm/user/showUser?id=1 -->
<input id="userName" value="${user.userName}">
</body>
</html>

哦,忘记配置tomcat，配置一下tomcat，然后部署发布项目，进行测试

到此，框架成!

其实，我们完全可以使用工具来自动生成IDao、Mapper，相关知识就请大家自行学习，不再一一列举。

总结：
   真心知道用maven之后，我们大框架真的方便多了，最起码不用个顶个的去找jar包，然后逐一的
导入，只需要在pom文件里面配置一下依赖，就好了。虽然说比较简单，可是可能是自己没有动手弄过
吧，期间除了各种各样的错，或者说是失误，但是，总之，耗时一天半，总算是通了，这也是收获，
加油吧，少（qing）年。
