【SSM】Eclipse使用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"
     xmlns:context="http://www.springframework.org/schema/context"
     xmlns:mvc="http://www.springframework.org/schema/mvc"
     xsi:schemaLocation="http://www.springframework.org/schema/beans
                         http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
                         http://www.springframework.org/schema/context

                         http://www.springframework.org/schema/mvc
                         http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">


     <context:annotation-config />


     <context:component-scan base-package="com.ssm" />


     <import resource="spring-dao.xml"/>


     <import resource="spring-db.xml"/>


     <import resource="spring-tx.xml"/>

 beans>

 

 

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
 #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

 

 

配置日志：log4j.properties

 

 #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
 log4j.appender.Console.layout = org.apache.log4j.PatternLayout
 log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

 #文件大小到达指定尺寸的时候产生一个新的文件
 log4j.appender.File = org.apache.log4j.RollingFileAppender
 #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
 log4j.appender.File.Threshold = ALL
 log4j.appender.File.layout = org.apache.log4j.PatternLayout
 log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

配置我们的ioc注入：spring-dao.xml

配置spring的事务管理器：spring-tx.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.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 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 queryUserByBatch(Map params);

     public void insertUser(User user);

     public void insertUserByBatch(List list);

     public void deleteByPrimaryKey(Integer id);

     public void delteUserByBatch(Map params);

     public void updateByPrimaryKey(Integer id);

     public List getAllUser();

 }

 

 

User.java:

 

 package com.ssm.dto;

 public class User {
     private Integer id;

     private String name;

     private String password;

     public Integer getId() {
         return id;
     }

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

     public String getName() {
         return name;

IUserService.java:

 

 

 package com.ssm.service;

 import java.util.List;

 import com.ssm.dto.User;

 public interface IUserService {

     public User getUserById(int userId);

     public void insertUser(User user);

     public void addUser(User user);

     public List getAllUser();
 }

UserServiceImpl.java:

 package com.ssm.service.Impl;

 import java.util.List;

 import javax.annotation.Resource;

 import org.springframework.stereotype.Service;

 import com.ssm.dao.IUserDao;
 import com.ssm.dto.User;
 import com.ssm.service.IUserService;

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

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

     public void insertUser(User user) {
         userDao.insertUser(user);
     }

     public void addUser(User user) {
         userDao.insertUser(user);
     }

     @Override
     public List getAllUser() {
         return userDao.getAllUser();
     }

 }

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

 

userinfo.jsp:

 

 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
 <%
 String path = request.getContextPath();
 String basePath=request.getSSScheme()+"://request.getServerName()"+":"+request.getServerPort+Path+
   "/"%>
 >
 <html>
   <head>
     <base href="<%=basePath%>">

     <title>My JSP 'userinfo.jsp' starting pagetitle>

     <meta http-equiv="pragma" content="no-cache">
     <meta http-equiv="cache-control" content="no-cache">

   head>

   <body>
     <form id="addUser" action="user/addUser" method="post">

         <input type="submit" value="添加新用户"/>
     form>

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

 

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。
