【SSH】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">  
                          
    <!-- 使用注解式注入 -->  
    <context:annotation-config />  
      
    <!-- 自动扫描 -->  
    <context:component-scan base-package="com.chillax" />  
      
    <!-- 导入DAO配置 -->  
    <import resource="spring-dao.xml"/>  
      
    <!-- 导入数据库配置 -->  
    <import resource="spring-db.xml"/>  
      
    <!-- 导入数据库配置 -->  
    <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<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> queryUserByBatch(Map<String,Object> params);  
      
    public void insertUser(User user);  
      
    public void insertUserByBatch(List<User> list);  
      
    public void deleteByPrimaryKey(Integer id);  
      
    public void delteUserByBatch(Map<String,Object> params);  
      
    public void updateByPrimaryKey(Integer id);  
  
    public List<User> 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:

        </set>    
        where id = #{id,jdbcType=INTEGER}   
    </update>  
    
</mapper>  

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<User> 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<User> 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"%>  
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>  
<%  
String path = request.getContextPath();  
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  
%>  
  
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">  
<html>  
  <head>  
    <base href="<%=basePath%>">  
      
    <title>My JSP 'userinfo.jsp' starting page</title>  
      
    <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">  
    <!-- 
    <link rel="stylesheet" type="text/css" href="styles.css"> 
    -->  
  
  </head>  
    
  <body>  
    <c:forEach items="${uList }" var="u">  
        用户名称:${u.name}  
        <br/>  
    </c:forEach>  
  </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。
