• SSM框架整合

    SSM框架整合

    1，开发环境的搭建

    JDK+Eclipse+Tomcat+Maven的安装与配置

    参考：http://blog.csdn.net/zhshulin/article/details/30779873

    2，Maven Web项目创建

    创建一个Maven项目来配置环境

    参考：http://blog.csdn.net/zhshulin/article/details/37921705

    3，SSM的整合

    2个配置文件：

    ① spring-mybatis.xml，包含spring和mybatis的配置文件，

    ②spring-mvc的配置文件，

    2个资源文件：

    ①jdbc.propertis

    ②log4j.properties

    目录结构：

     

    3.1框架中引入的Jar包（pom.xml配置，也可以直接导入包）

    3.2、Spring与MyBatis的整合

    所有需要的JAR包都引入以后，首先进行Spring与MyBatis的整合，然后再进行JUnit测试，

    3.2.1、建立JDBC属性文件（jdbc.properties，文件编码修改为utf-8）

     1 #<?xml version="1.0" encoding="UTF-8"?>
 2 driver=com.mysql.jdbc.Driver
 3 url=jdbc:mysql://localhost:3306/数据库名?useUnicode=true&characterEncoding=utf8
 4 username=用户名
 5 password=密码
 6 #定义初始连接数
 7 initialSize=0
 8 #定义最大连接数
 9 maxActive=20
10 #定义最大空闲
11 maxIdle=20
12 #定义最小空闲
13 minIdle=1
14 #定义最长等待时间
15 maxWait=60000

    3.2.2、建立spring-mybatis.xml配置文件

      这个文件就是用来完成spring和mybatis的整合的，主要的就是自动扫描，自动注入，配置数据库。

     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     <!-- 自动扫描 -->
13     <context:component-scan base-package="com.projMgr（包名要改）" />
14     <!-- 引入配置文件<property resource="classpath:jdbc.properties" /> -->
15     <bean id="propertyConfigurer"
16         class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
17         <property name="location" value="classpath:jdbc.properties" />
18         
19     </bean>
20     
21     <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
22         destroy-method="close">
23         <property name="driverClassName" value="${driver}" />
24         <property name="url" value="${url}" />
25         <property name="username" value="${username}" />
26         <property name="password" value="${password}" />
27         <!-- 初始化连接大小 -->
28         <property name="initialSize" value="${initialSize}"></property>
29         <!-- 连接池最大数量 -->
30         <property name="maxActive" value="${maxActive}"></property>
31         <!-- 连接池最大空闲 -->
32         <property name="maxIdle" value="${maxIdle}"></property>
33         <!-- 连接池最小空闲 -->
34         <property name="minIdle" value="${minIdle}"></property>
35         <!-- 获取连接最大等待时间 -->
36         <property name="maxWait" value="${maxWait}"></property>
37     </bean>
38 
39     <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
40     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
41         <property name="dataSource" ref="dataSource" />
42         <!-- 自动扫描mapping.xml文件 -->
43         <property name="mapperLocations" value="classpath:com/projMgr/mapping/*.xml"></property>
44     </bean>
45 
46         <!-- DAO接口所在包名，Spring会自动查找其下的类 -->
47     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
48         <property name="basePackage" value="com.projMgr.Dao" />
49         <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
50     </bean>
51 
52     <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
53     <bean id="transactionManager"
54         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
55         <property name="dataSource" ref="dataSource" />
56     </bean>
57 </beans>

    3.2.3、Log4j的配置（log4j.properties）

    为了方便调试，一般都会使用日志来输出信息，Log4j是Apache的一个开放源代码项目，通过使用Log4j，我们可以控制日志信息输送的目的地是控制台、文件、GUI组件，甚至是套接口服务器、NT的事件记录器、UNIX Syslog守护进程等；我们也可以控制每一条日志的输出格式；通过定义每一条日志信息的级别，我们能够更加细致地控制日志的生成过程。

     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

    3.2.4、JUnit测试

      经过以上步骤（log4j不配也没影响），我们已经完成了Spring和mybatis的整合，这样我们就可以编写一段测试代码来试试是否成功了。

    3.2.4.1、创建测试用表
     1 DROP TABLE IF EXISTS `user`;
 2 
 3 CREATE TABLE `user` (
 4 
 5   `id` int(11) NOT NULL AUTO_INCREMENT,
 6 
 7   `user_name` varchar(40) NOT NULL,
 8 
 9   `password` varchar(255) NOT NULL,
10 
11   `age` int(4) NOT NULL,
12 
13   PRIMARY KEY (`id`)
14 
15 ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
16 
17 /*Data for the table `user` */
18 
19 insert  into `user`(`id`,`user_name`,`password`,`age`) values (1,'张三','2013',4);
    3.2.4.2、利用MyBatis Generator自动创建代码

    参考：

    http://blog.csdn.net/zhshulin/article/details/23912615

    http://www.cnblogs.com/smileberry/p/4145872.html

    这个可根据表自动创建实体类、MyBatis映射文件以及DAO接口，复制到项目中。

    建立文件夹，所需文件：

     

    generatorConfig.xml文件：

     1 <?xml version="1.0" encoding="UTF-8"?>    
 2     <!DOCTYPE generatorConfiguration    
 3       PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"    
 4       "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">    
 5     <generatorConfiguration>    
 6     <!-- 数据库驱动-->    
 7         <classPathEntry  location="mysql-connector-java-5.1.30.jar"/>    
 8         <context id="DB2Tables"  targetRuntime="MyBatis3">    
 9             <commentGenerator>    
10                 <property name="suppressDate" value="true"/>    
11                 <!-- 是否去除自动生成的注释 true：是 ： false:否 -->    
12                 <property name="suppressAllComments" value="true"/>    
13             </commentGenerator>    
14             <!--数据库链接URL，用户名、密码 -->    
15             <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/数据库名称" userId="用户名" password="密码">    
16             </jdbcConnection>    
17             <javaTypeResolver>    
18                 <property name="forceBigDecimals" value="false"/>    
19             </javaTypeResolver>    
20             <!-- 生成模型的包名和位置-->    
21             <javaModelGenerator targetPackage="test.model" targetProject="src">    
22                 <property name="enableSubPackages" value="true"/>    
23                 <property name="trimStrings" value="true"/>    
24             </javaModelGenerator>    
25             <!-- 生成映射文件的包名和位置-->    
26             <sqlMapGenerator targetPackage="test.mapping" targetProject="src">    
27                 <property name="enableSubPackages" value="true"/>    
28             </sqlMapGenerator>    
29             <!-- 生成DAO的包名和位置-->    
30             <javaClientGenerator type="XMLMAPPER" targetPackage="test.IDao" targetProject="src">    
31                 <property name="enableSubPackages" value="true"/>    
32             </javaClientGenerator>    
33             <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->    
34             <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>  
35         </context>    
36     </generatorConfiguration>

    在mybatis-generator-core-1.3.2文件所在处，按住shift，右键，选择“在此处打开命令窗口”，黏贴一下代码，回车运行。

     1 java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite 

     运行结果：

    生成结果：

     复制到项目中，并修改目录、文件名称

     

    3.2.4.3、建立Service接口和实现类

    目录结构：

     

    以下是具体代码：

    IUserService.java

    1 package com.projMgr.service;
2 
3 import java.util.List;
4 
5 import com.projMgr.pojo.User;
6 
7 public interface IUserService {
8     public User getUserById(int userId);
9 }

    UserServiceImpl.java

     1 package com.projMgr.service;
 2 
 3 import java.util.List;
 4 
 5 import javax.annotation.Resource;
 6 
 7 import org.springframework.stereotype.Service;
 8 
 9 import com.projMgr.Dao.IUserDao;
10 import com.projMgr.pojo.User;
11 import com.projMgr.service.IUserService;
12 
13 @Service("userService")
14 public class UserServiceImpl implements IUserService {
15     @Resource
16     private IUserDao userDao;
17     @Override
18     public User getUserById(int userId) {
19         return this.userDao.selectByPrimaryKey(userId);
20     }
21 
22 }
    3.2.4.4、建立测试类

    测试类在src/test/java中建立，下面测试类中注释掉的部分是不使用Spring时，一般情况下的一种测试方法；如果使用了Spring那么就可以使用注解的方式来引入配置文件和类，然后再将service接口对象注入，就可以进行测试了。

           如果测试成功，表示Spring和Mybatis已经整合成功了。输出信息使用的是Log4j打印到控制台。

     

    TestMyBatis.java

     1 package org.projMgr.testmybatis;
 2 
 3 import javax.annotation.Resource;
 4 
 5 import org.apache.log4j.Logger;
 6 //import org.junit.Before;
 7 import org.junit.Test;
 8 import org.junit.runner.RunWith;
 9 //import org.springframework.context.ApplicationContext;

    测试结果：

     

     

    如果测试成功，则完成Spring和mybatis这两大框架的整合，下面在继续进行SpringMVC的整合。

    3.3、整合SpringMVC

    上面已经完成了2大框架的整合，SpringMVC的配置文件单独放，然后在web.xml中配置整合。

    3.3.1、配置spring-mvc.xml

    配置主要是自动扫描控制器，视图模式，注解的启动这三个。

    spring-mvc.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     <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
13     <context:component-scan base-package="com.projMgr.controller(包名需改)" />
14     <!--避免IE执行AJAX时，返回JSON出现下载文件 -->
15     <bean id="mappingJacksonHttpMessageConverter"
16         class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
17         <property name="supportedMediaTypes">
18             <list>
19                 <value>text/html;charset=UTF-8</value>
20             </list>
21         </property>
22     </bean>
23     <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->
24     <bean
25         class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
26         <property name="messageConverters">
27             <list>
28                 <ref bean="mappingJacksonHttpMessageConverter" />    <!-- JSON转换器 -->
29             </list>
30         </property>
31     </bean>
32     <!-- 定义跳转的文件的前后缀 ，视图模式配置-->
33     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
34         <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->
35         <property name="prefix" value="/WEB-INF/jsp/" />
36         <property name="suffix" value=".jsp" />
37     </bean>
38     
39     <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->
40     <bean id="multipartResolver"  
41         class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
42         <!-- 默认编码 -->
43         <property name="defaultEncoding" value="utf-8" />  
44         <!-- 文件大小最大值 -->
45         <property name="maxUploadSize" value="10485760000" />  
46         <!-- 内存中的最大值 -->
47         <property name="maxInMemorySize" value="40960" />  
48     </bean> 
49 
50 </beans>

     

    3.3.2、配置web.xml文件

     这里面对spring-mybatis.xml的引入以及配置的spring-mvc的Servlet就是为了完成SSM整合

    web.xml

     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"
 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">

12     </context-param>
13     
14     <!-- 编码过滤器 -->
15     <filter>
16         <filter-name>encodingFilter</filter-name>
17         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
18         <async-supported>true</async-supported>
19         <init-param>

22         </init-param>
23     </filter>
24     <filter-mapping>
25         <filter-name>encodingFilter</filter-name>
26         <url-pattern>/*</url-pattern>
27     </filter-mapping>
28     <!-- Spring监听器 -->
29     <listener>
30         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
31     </listener>
32     <!-- 防止Spring内存溢出监听器 -->
33     <listener>
34         <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
35     </listener>
36 
37     <!-- Spring MVC servlet -->
38     <servlet>
39         <servlet-name>SpringMVC</servlet-name>

48     <servlet-mapping>
49         <servlet-name>SpringMVC</servlet-name>
50         <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
51         <url-pattern>/</url-pattern>
52     </servlet-mapping>
53     <welcome-file-list>
54         <welcome-file>/index.jsp</welcome-file>
55     </welcome-file-list>
56     <!-- 配置SESSION超时，单位是分钟 -->
57     <session-config>
58         <session-timeout>30</session-timeout>
59     </session-config>
60 </web-app>

    3.3.3、测试

       至此已经完成了SSM三大框架的整合了，接下来测试一下，如果成功了即可。

    3.3.3.1、新建jsp页面

     

    showUser.jsp 

     1 <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
 2 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 3 <html>
 4 <head>
 5     <title>测试</title>
 6 </head>
 7 
 8 <body>
 9 ${user.userName}
10 ${user.password}
11 </body>
12 </html>
    3.3.3.2、建立UserController类

    UserController.java 

     1 package com.projMgr.controller;
 2 
 3 import java.util.List;
 4 
 5 import javax.annotation.Resource;
 6 import javax.servlet.http.HttpServletRequest;
 7 
 8 //import org.springframework.beans.factory.annotation.Autowired;
 9 import org.springframework.stereotype.Controller;
10 import org.springframework.ui.Model;
11 //import org.springframework.ui.Model;
12 import org.springframework.web.bind.annotation.RequestMapping;
13 import com.projMgr.pojo.User;
14 import com.projMgr.service.IUserService;
15 
16 @Controller
17 @RequestMapping("/user")
18 public class UserController {
19     @Resource
20     private IUserService userService;
21     
22     @RequestMapping("/showUser")
23     public String toIndex(HttpServletRequest request,Model model){
24         int userId = Integer.parseInt(request.getParameter("id"));
25         User user = this.userService.getUserById(userId);
26         model.addAttribute("user", user);
27         return "/showUser";
28     }
29     
30     
31 }
    3.3.3.3、部署项目

    tomcat8.0启动，成功日志：（可用于出错对照）

    输入地址：localhost:端口号/项目名称/user/showUser?id=1

     

    如图，这样，基本的框架就搭建完成了！

     

    4，过程错误

    4.1情况1:

    Project configuration is not up-to-date with pom.xml. Run Maven->Update Project or use Quick Fix.

    在Problems View的出错提示右键选Quick Fix,再按提示确定就OK.或者,右键项目->Maven->Update Project

    4.2情况2:

    JavaServer Faces 2.2 can not be installed : One or more constraints have not been satisfied.
    JavaServer Faces 2.2 requires Dynamic Web Module 2.5 or newer.
    先改web.xmlwebapp节点:
    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    version="3.1">
    </web-app>

    然后关闭Eclipse,改项目下的.settingsorg.eclipse.wst.common.project.facet.core.xml.将版本改成为3.1,将成后是<installed facet="jst.web" version="3.1"/>,再启动Eclipse.最后出现上面的情况1,按上面更新下配置就OK.

    4.3情况3:


    情况3:
    JDK版本设置：
    pom.xml配置
      <build>
        <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
