【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:

 

  1. <?xml version="1.0" encoding="UTF-8"?>    
  2. <beans xmlns="http://www.springframework.org/schema/beans"    
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"    
  4.     xmlns:context="http://www.springframework.org/schema/context"    
  5.     xmlns:mvc="http://www.springframework.org/schema/mvc"    
  6.     xsi:schemaLocation="http://www.springframework.org/schema/beans      
  7.                         http://www.springframework.org/schema/beans/spring-beans-3.1.xsd      
  8.                         http://www.springframework.org/schema/context      
  9.                         http://www.springframework.org/schema/context/spring-context-3.1.xsd      
  10.                         http://www.springframework.org/schema/mvc      
  11.                         http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">    
  12.                             
  13.     <!-- 使用注解式注入 -->    
  14.     <context:annotation-config />    
  15.         
  16.     <!-- 自动扫描 -->    
  17.     <context:component-scan base-package="com.ssm" />    
  18.         
  19.     <!-- 导入DAO配置 -->

  24.         
  25.     <!-- 导入数据库配置 -->    
  26.     <import resource="spring-tx.xml"/>    
  27.         
  28. </beans>    

 

 

配置数据库连接池:jdbc.properties

 

 

  1. driver=com.mysql.jdbc.Driver    
  2. url=jdbc:mysql://localhost:3306/maven_ssm    
  3. username=root    
  4. password=root    
  5. #定义初始连接数    
  6. initialSize=0    
  7. #定义最大连接数    
  8. maxActive=20    
  9. #定义最大空闲    
  10. maxIdle=20    
  11. #定义最小空闲    
  12. minIdle=1    
  13. #定义最长等待时间    
  14. maxWait=60000    

 

 

配置日志:log4j.properties

 

  1. #定义LOG输出级别    
  2. log4j.rootLogger=INFO,Console,File    
  3. #定义日志输出目的地为控制台    
  4. log4j.appender.Console=org.apache.log4j.ConsoleAppender    
  5. log4j.appender.Console.Target=System.out    
  6. #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    
  7. log4j.appender.Console.layout = org.apache.log4j.PatternLayout    
  8. log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n    
  9.     
  10. #文件大小到达指定尺寸的时候产生一个新的文件    
  11. log4j.appender.File = org.apache.log4j.RollingFileAppender    
  12. #指定输出目录    
  13. log4j.appender.File.File = logs/ssm.log    
  14. #定义文件最大大小    
  15. log4j.appender.File.MaxFileSize = 10MB    
  16. # 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志    
  17. log4j.appender.File.Threshold = ALL    
  18. log4j.appender.File.layout = org.apache.log4j.PatternLayout    
  19. 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

 

 

  1. <?xml version="1.0" encoding="UTF-8"?>    
  2. <beans xmlns="http://www.springframework.org/schema/beans"    
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

配置spring的事务管理器:spring-tx.xml

 

 

  1. <?xml version="1.0" encoding="UTF-8"?>    
  2. <beans xmlns="http://www.springframework.org/schema/beans"    
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

接下来,我们来整合spring mvc:spring-mvc.xml:

 

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

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:

  1. package com.ssm.controller;    
  2.     
  3. import java.util.List;    
  4.     
  5. import javax.annotation.Resource;    
  6. import javax.servlet.http.HttpServletRequest;    
  7.     
  8. import org.springframework.stereotype.Controller;    
  9. import org.springframework.ui.Model;    
  10. import org.springframework.web.bind.annotation.RequestMapping;    
  11.     
  12. import com.ssm.dto.User;    
  13. import com.ssm.service.IUserService;    
  14.     
  15. @Controller    
  16. @RequestMapping("/user")    
  17. public class UserController {    
  18.     @Resource    
  19.     private IUserService userService;    
  20.         
  21.     @RequestMapping("/userList")    
  22.     public String userList(HttpServletRequest request,Model model){    
  23.         List<User> uList = userService.getAllUser();    
  24.         model.addAttribute("uList", uList);    
  25.         return "userList";    
  26.     }    
  27.         
  28.     @RequestMapping("/showUser")    
  29.     public String showUser(HttpServletRequest request,Model model){    
  30.         int userId = Integer.parseInt(request.getParameter("id"));    
  31.         User user = userService.getUserById(userId);    
  32.         model.addAttribute("user", user);    
  33.         return "showUser";    
  34.     }    
  35.         
  36.     @RequestMapping("/addUserUI")    
  37.     public String addUserUI(){    
  38.         return "addUser";    
  39.     }    
  40.         
  41.     @RequestMapping("/addUser")    
  42.     public String addUser(HttpServletRequest request,Model model){    
  43.         User user = new User();    
  44.         user.setName(String.valueOf(request.getParameter("name")));    
  45.         user.setPassword(String.valueOf(request.getParameter("password")));    
  46.         user.setAge(Integer.parseInt(String.valueOf(request.getParameter("age"))));    
  47.         userService.addUser(user);    
  48.         return "redirect:/user/userList";    
  49.     }    
  50. }    

 

 

IUserDao.java:

 

  1. package com.ssm.dao;    
  2.     
  3. import java.util.List;    
  4. import java.util.Map;    
  5.     
  6. import com.ssm.dto.User;    
  7.     
  8. public interface IUserDao {    
  9.         
  10.     public User queryByPrimaryKey(Integer id);    
  11.         
  12.     public List<User> queryUserByBatch(Map<String,Object> params);    
  13.

  19.         
  20.     public void delteUserByBatch(Map<String,Object> params);    
  21.         
  22.     public void updateByPrimaryKey(Integer id);    
  23.     
  24.     public List<User> getAllUser();    
  25.         
  26. }    

 

 

User.java:

 

  1. package com.ssm.dto;    
  2.     
  3. public class User {    
  4.     private Integer id;    
  5.     
  6.     private String name;    
  7.

  27.         return password;    
  28.     }    
  29.     
  30.     public void setPassword(String password) {    
  31.         this.password = password == null ? null : password.trim();    
  32.     }    
  33. }

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:

 

  1. <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>    
  2. <%    
  3. String path = request.getContextPath();

  6. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">    
  7. <html>    
  8.   <head>    
  9.     <base href="<%=basePath%>">    
  10.

  21.     
  22.   </head>    
  23.       
  24.   <body>    
  25.     <form id="addUser" action="user/addUser" method="post">     
  26.         userName: <input id="name" name="name" /><br/>     
  27.         password: <input id="password" name="password" /><br/>    
  28.         <input type="submit" value="添加新用户"/>     
  29.     </form>    
  30.   </body>    
  31. </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。
