Maven 搭建 SSM框架——Spring+SpringMVC+Mybatis的搭建教程

一:概述
SSM框架在项目开发中经常使用到,相比于SSH框架,它在仅几年的开发中运用的更加广泛。

Spring作为一个轻量级的框架,有很多的拓展功能,最主要的我们一般项目使用的就是IOC和AOP。
SpringMVC是Spring实现的一个Web层,相当于Struts的框架,但是比Struts更加灵活和强大!
Mybatis是 一个持久层的框架,在使用上相比Hibernate更加灵活,可以控制sql的编写,使用 XML或注解进行相关的配置!
根据上面的描述,学习SSM框架就非常的重要了!

二:搭建一个SSM的过程

使用Maven管理项目
使用Maven在Eclipse中创建一个webapp的项目 ,具体的创建过程不做演示,如有不会创建的创建项目
也可以使用Maven命令进行创建,在Dos窗口进入指定的目录,执行下面命令:

mvn archetype:create -DgroupId=org.ssm.dufy -DartifactId=ssm-demo 
-DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

使用命令要注意,系统安装了Maven,并配置好了环境变量!Maven的安装和环境变量配置

  1、导入项目(命名创建),添加依赖 

    如下项目结构:

    

    然后直接配置 pom.xml文件中的包依赖!

  2、创建数据库和表,生成代码 

  创建数据库我参考别人的博客数据库设计,这块没有自己去书写,直接添上代码

 1 DROP TABLE IF EXISTS `user_t`;  
 2 
 3 CREATE TABLE `user_t` (  
 4   `id` int(11) NOT NULL AUTO_INCREMENT,  
 5   `user_name` varchar(40) NOT NULL,  
 6   `password` varchar(255) NOT NULL,  
 7   `age` int(4) NOT NULL,  
 8   PRIMARY KEY (`id`)  
 9 ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;  
10 
11 /*Data for the table `user_t` */  
12 
13 insert  into `user_t`(`id`,`user_name`,`password`,`age`) values (1,'测试','123456',24)

 生成代码请查看: 

  Mybatis自动生成代码

  生成的代码导入图片解释:

 

  3、Spring 和 mybatis整合,连接数据库,进行Junit测试 
    将生成的代码拷贝到项目中,然后进行Spring和Mybatis的整合,添加配置文件!

 

  主要有
  applicationContent.xml :Spring的相关配置!
  Spring-mhbatis.xml : Spring和Mybatis集成配置!
  jdbc.properties : 数据库信息配置!
  logback.xml : 日志输出信息配置!(不做介绍,详细信息查看源码)

  主要介绍applicationContext.xml、Spring-mhbatis.xml、jdbc.properties。主要内容如下:

  jdbc.properties

1 jdbc_driverClassName =com.mysql.jdbc.Driver
2 jdbc_url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8
3 jdbc_username=root
4 jdbc_password=root

  applicationContext.xml

  4、测试代码,两种方式:

  测试1:

 1 package org.ssm.dufy.service;
 2 
 3 import org.junit.Test;
 4 import org.junit.runner.RunWith;
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.test.context.ContextConfiguration;
 7 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
 8 import org.ssm.dufy.entity.User;
 9 
10 /**
11  * 配置spring和junit整合,junit启动时加载springIOC容器 spring-test,junit
12  */
13 @RunWith(SpringJUnit4ClassRunner.class)
14 // 告诉junit spring配置文件
15 @ContextConfiguration({ "classpath:applicationContext.xml"})
16 public class IUserServiceTest {
17 
18     @Autowired
19     public IUserService userService;
20 
21     @Test
22     public void getUserByIdTest(){
23 
24         User user = userService.getUserById(1);
25         System.out.println(user.getUserName());
26     }
27 
28 }

  测试2

 1 package org.ssm.dufy.service;
 2 
 3 import org.springframework.context.ApplicationContext;
 4 import org.springframework.context.support.ClassPathXmlApplicationContext;
 5 import org.ssm.dufy.entity.User;
 6 
 7 public class IUserServiceTest2 {
 8 
 9 
10     public static void main(String[] args) {
11         ApplicationContext application = new ClassPathXmlApplicationContext("applicationContext.xml");
12         IUserService uService = (IUserService) application.getBean("userService");
13         User user = uService.getUserById(1);
14         System.out.println(user.getUserName());
15     }
16 }

  5、整合SpringMVC,添加配置,创建jsp 

  SpringMVC需要的依赖在pom.xml中已经加上了,现在需在Web项目中的web.xml中添加启动SpringMVC启动配置和Spring整合SpringMVC的配置了。 
  新增如下两个文件: 

 

 spring-mvc.xml

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

11     http://www.springframework.org/schema/context/spring-context-3.2.xsd
12     http://www.springframework.org/schema/mvc
13     http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
14 
15     <!-- 扫描controller(controller层注入) -->
16    <context:component-scan base-package="org.ssm.dufy.web" use-default-filters="false">
17         <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
18     </context:component-scan>
19 
20      <mvc:annotation-driven />
21 
22       <!-- 内容协商管理器  -->
23     <!--1、首先检查路径扩展名(如my.pdf);2、其次检查Parameter(如my?format=pdf);3、检查Accept Header-->
24     <bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
25         <!-- 扩展名至mimeType的映射,即 /user.json => application/json -->
26         <property name="favorPathExtension" value="true"/>
27         <!-- 用于开启 /userinfo/123?format=json 的支持 -->
28         <property name="favorParameter" value="true"/>
29         <property name="parameterName" value="format"/>
30         <!-- 是否忽略Accept Header -->
31         <property name="ignoreAcceptHeader" value="false"/>
32 
33         <property name="mediaTypes"> <!--扩展名到MIME的映射;favorPathExtension, favorParameter是true时起作用  -->
34             <value>
35                 json=application/json
36                 xml=application/xml
37                 html=text/html
38             </value>
39         </property>
40         <!-- 默认的content type -->
41         <property name="defaultContentType" value="text/html"/>
42     </bean>
43 
44 
45     <!-- 当在web.xml 中   DispatcherServlet使用 <url-pattern>/</url-pattern> 映射时,能映射静态资源 -->
46     <mvc:default-servlet-handler />  
47     <!-- 静态资源映射 -->
48     <mvc:resources mapping="/static/**" location="/WEB-INF/static/"/>
49 
50

66   <welcome-file-list>
67     <welcome-file>index.jsp</welcome-file>
68   </welcome-file-list>
69 </web-app>

  新增index.jsp文件

1 <%@ page contentType="text/html; charset=utf-8"%>
2 <!doctype html>
3 <html>
4 <body>
5 <h2>Hello World!</h2>
6 </body>
7 </html>

 

  6、启动web服务,测试
  将上面的项目添加到Tomcat中,启动,控制台没有报错,并在地址栏访问,http://localhost:8080/quartz。页面显示 Hello World! 项目配置ok!

  7、编写Controller,和对应得业务界面
  新增UserController ,通过参数传递uid获取用户,若用户存在,跳转到showName.jsp ,若用户不存在,则跳转到error.jsp,并返回提示信息!

 1 package org.ssm.dufy.web;
 2 
 3 import javax.servlet.http.HttpServletRequest;
 4 
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.stereotype.Controller;
 7 import org.springframework.ui.Model;
 8 import org.springframework.web.bind.annotation.RequestMapping;
 9 import org.springframework.web.bind.annotation.RequestMethod;
10 import org.springframework.web.bind.annotation.RequestParam;
11 import org.springframework.web.servlet.ModelAndView;
12 import org.ssm.dufy.entity.User;
13 import org.ssm.dufy.service.IUserService;
14 
15 @Controller
16 public class UserController {
17 
18     @Autowired
19     private IUserService userService;
20 
21     @RequestMapping(value="/showname",method=RequestMethod.GET)
22     public String showUserName(@RequestParam("uid") int uid,HttpServletRequest request,Model model){
23         System.out.println("showname");
24         User user = userService.getUserById(uid);
25         if(user != null){
26             request.setAttribute("name", user.getUserName());
27             model.addAttribute("mame", user.getUserName());
28             return "showName";
29         }
30         request.setAttribute("error", "没有找到该用户!");
31         return "error";
32     }
33 }

   Jsp内容如下:

  showName.jsp

 1 <%@ page contentType="text/html; charset=utf-8"%>
 2 <!doctype html>
 3 <html>
 4 <head>
 5     <title>show name</title>
 6 </head>
 7 <body>
 8     <h1>Welcome</h1> ${name }<h1>访问此页面</h1>
 9 
10 </body>
11 </html>

  error.jsp

 1 <%@ page contentType="text/html; charset=utf-8"%>
 2 <!doctype html>
 3 <html>
 4 <head>
 5     <title>error page</title>
 6 </head>
 7 <body>
 8     <h2> ${error } </h2>
 9 
10 </body>
11 </html>

 

 三:遇到的问题 
  1、找不到UserService,报错

可能是包扫描路径的问题,检查一下Service是否在扫描的范围内

  2、jsp接收不到request.setAttribute(“”,”“);内容

查资料说是因为 JSP的版本问题,可以在Jsp 上面添加 <%@ page isELIgnored=”false” %> 
或者修改web.xml ,添加version版本!
1 <?xml version="1.0" encoding="UTF-8"?>
2 
3 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4     xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
5     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
6     id="WebApp_ID" version="3.0" metadata-complete="true">
