Maven创建Web项目、、、整合SSM框架
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
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:
3、右击项目,选择Properties进行一些配置:
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:applicationContext.xml:
- <?xml version="1.0" encoding="UTF-8"?>
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

配置数据库连接池:jdbc.properties
- driver=com.mysql.jdbc.Driver
- url=jdbc:mysql://localhost:3306/maven_ssm
- username=root
- password=root
- #定义初始连接数
- initialSize=0

配置日志:log4j.properties
- #定义LOG输出级别

- #指定输出目录
- log4j.appender.File.File = logs/ssm.log
- #定义文件最大大小
- log4j.appender.File.MaxFileSize = 10MB
- # 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志

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.ssm.controller;
- import java.util.List;
- 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.ssm.dto.User;
- import com.ssm.service.IUserService;
- @Controller
- @RequestMapping("/user")
- public class UserController {
- @Resource
- private IUserService userService;
- @RequestMapping("/userList")
- public String userList(HttpServletRequest request,Model model){
- List<User> uList = userService.getAllUser();
- model.addAttribute("uList", uList);
- return "userList";
- }
- @RequestMapping("/showUser")
- public String showUser(HttpServletRequest request,Model model){
- int userId = Integer.parseInt(request.getParameter("id"));
- User user = userService.getUserById(userId);
- model.addAttribute("user", user);
- return "showUser";
- }
- @RequestMapping("/addUserUI")
- public String addUserUI(){
- return "addUser";
- }
- @RequestMapping("/addUser")
- public String addUser(HttpServletRequest request,Model model){
- User user = new User();
- user.setName(String.valueOf(request.getParameter("name")));
- user.setPassword(String.valueOf(request.getParameter("password")));
- user.setAge(Integer.parseInt(String.valueOf(request.getParameter("age"))));
- userService.addUser(user);
- return "redirect:/user/userList";
- }
- }
IUserDao.java:
- package com.ssm.dao;
- import java.util.List;
- import java.util.Map;
- import com.ssm.dto.User;
- public interface IUserDao {
- public User queryByPrimaryKey(Integer id);

- public List<User> getAllUser();
- }
User.java:
- package com.ssm.dto;
- public class User {
