【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/context/spring-context-3.1.xsd
                        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

        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />

接下来，我们来整合spring mvc：spring-mvc.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;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

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

UserMapper.xml:

 

 

xml version="1.0" encoding="UTF-8" ?>
>
<mapper namespace="com.ssm.dao.IUserDao" >
    <resultMap id="BaseResultMap" type="com.ssm.dto.User">

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">
    <meta http-equiv="expires" content="0">
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">


  head>

  <body>
    <form id="addUser" action="user/addUser" method="post">
        userName: <input id="name" name="name" /><br/>
        password: <input id="password" name="password" /><br/>
        <input type="submit" value="添加新用户"/>
    form>
  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

 

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。
