参考了同事的文档，自己也写一篇文档。
同时，补充了一下，程序是如何运行的。
一：SSM框架
1.说明
SSM（Spring+SpringMVC+MyBatis）框架集由Spring、SpringMVC、MyBatis三个开源框架整合而成，常作为数据源较简单的web项目的框架。
2.每个框架的功能
其中spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。
SpringMVC分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。
MyBatis是一个支持普通SQL查询，存储过程和高级映射的优秀持久层框架。
页面发送请求给控制器，控制器调用业务层处理逻辑，逻辑层向持久层发送请求，持久层与数据库交互，后将结果返回给业务层，业务层将处理逻辑发送给控制器，控制器再调用视图展现数据。
二：新建项目
1.程序大纲
2.使用软件
IDEA
3.新建Maven项目
4.定位
5.设置maven
6.项目保存路径
三：到目前为止的效果
1.大纲
2.配置tomcat
3.clean install
4.运行效果
很奇怪，啥时候定位到index.jsp的呢。这个以后再研究。
5.web.xml
1 <!DOCTYPE web-app PUBLIC 2 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 3 "http://java.sun.com/dtd/web-app_2_3.dtd" > 4 5 <web-app> 6 <display-name>Archetype Created Web Application</display-name> 7 </web-app>
6.pom.xml
这个pom感觉有点繁。不过现在是生成的，就先原本粘贴了。

7.index.jsp
1 <html> 2 <body> 3 <h2>Hello World!</h2> 4 </body> 5 </html>
四：引入新的包
1.需要的最少的包
1 <?xml version="1.0" encoding="UTF-8"?> 2 3 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <modelVersion>4.0.0</modelVersion> 6 7 <groupId>jun.it</groupId> 8 <artifactId>ssm</artifactId> 9 <version>1.0-SNAPSHOT</version> 10 <packaging>war</packaging> 11 12 <name>ssm Maven Webapp</name> 13 14 <url>http://www.example.com</url> 15 16 <properties> 17 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 18 <maven.compiler.source>1.7</maven.compiler.source> 19 <maven.compiler.target>1.7</maven.compiler.target> 20 <!--自己新添加的版本--> 21 <junit.version>4.11</junit.version> 22 <mybatis.version>3.4.6</mybatis.version> 23 <mysql.version>8.0.11</mysql.version> 24 <spring.version>5.0.4.RELEASE</spring.version> 25 <mybatis-spring.version>1.3.2</mybatis-spring.version> 26 <commons-dbpc.version>1.4</commons-dbpc.version> 27 </properties> 28 29 <dependencies> 30 <!--测试--> 31 <dependency> 32 <groupId>junit</groupId> 33 <artifactId>junit</artifactId> 34 <version>${junit.version}</version> 35 <scope>test</scope> 36 </dependency> 37 38 <!-- dbcp数据源 --> 39 <dependency> 40 <groupId>commons-dbcp</groupId> 41 <artifactId>commons-dbcp</artifactId> 42 <version>${commons-dbpc.version}</version> 43 </dependency> 44 45 <!--mysql的连接包--> 46 <!--JDBC Type 4 driver for MySQL--> 47 <dependency> 48 <groupId>mysql</groupId> 49 <artifactId>mysql-connector-java</artifactId> 50 <version>${mysql.version}</version> 51 </dependency> 52 53 <!-- Mybatis3.4.1 --> 54 <dependency> 55 <groupId>org.mybatis</groupId> 56 <artifactId>mybatis</artifactId> 57 <version>${mybatis.version}</version> 58 </dependency> 59 60 <!-- spring整合mybatis --> 61 <!--An easy-to-use Spring bridge for MyBatis sql mapping framework.--> 62 <dependency> 63 <groupId>org.mybatis</groupId> 64 <artifactId>mybatis-spring</artifactId> 65 <version>${mybatis-spring.version}</version> 66 </dependency> 67 68 <!-- spring核心包 --> 69 <!--spring-core--> 70 <dependency> 71 <groupId>org.springframework</groupId> 72 <artifactId>spring-core</artifactId> 73 <version>${spring.version}</version> 74 </dependency> 75 76 <!--Spring JDBC--> 77 <dependency> 78 <groupId>org.springframework</groupId> 79 <artifactId>spring-jdbc</artifactId> 80 <version>${spring.version}</version> 81 </dependency> 82 83 <!--Spring WebMVC--> 84 <dependency> 85 <groupId>org.springframework</groupId> 86 <artifactId>spring-webmvc</artifactId> 87 <version>${spring.version}</version> 88 </dependency> 89 90 <!--Spring Context--> 91 <dependency> 92 <groupId>org.springframework</groupId> 93 <artifactId>spring-context</artifactId> 94 <version>${spring.version}</version> 95 </dependency> 96 97 <!-- https://mvnrepository.com/artifact/commons-pool/commons-pool --> 98 <dependency> 99 <groupId>commons-pool</groupId> 100 <artifactId>commons-pool</artifactId> 101 <version>1.6</version> 102 </dependency> 103 104 <build> 105 <finalName>ssm</finalName> 106 <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --> 107 <plugins> 108 <plugin> 109 <artifactId>maven-clean-plugin</artifactId> 110 <version>3.0.0</version> 111 </plugin> 112 <!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --> 113 <plugin> 114 <artifactId>maven-resources-plugin</artifactId> 115 <version>3.0.2</version> 116 </plugin> 117 <plugin> 118 <artifactId>maven-compiler-plugin</artifactId> 119 <version>3.7.0</version> 120 </plugin> 121 <plugin> 122 <artifactId>maven-surefire-plugin</artifactId> 123 <version>2.20.1</version> 124 </plugin> 125 <plugin> 126 <artifactId>maven-war-plugin</artifactId> 127 <version>3.2.0</version> 128 </plugin> 129 <plugin> 130 <artifactId>maven-install-plugin</artifactId> 131 <version>2.5.2</version> 132 </plugin> 133 <plugin> 134 <artifactId>maven-deploy-plugin</artifactId> 135 <version>2.8.2</version> 136 </plugin> 137 </plugins> 138 </pluginManagement> 139 <!----> 140 <resources> 141 <resource> 142 <directory>src/main/java</directory> 143 <includes> 144 <include>mapper/*.xml</include> 145 </includes> 146 </resource> 147 <resource> 148 <directory>src/main/resource</directory> 149 <includes> 150 <include>config/*</include> 151 </includes> 152 </resource> 153 </resources> 154 </build> 155 156 157 </project>
2.剩下的自己选择使用
1 <dependency> 2 <groupId>org.springframework</groupId> 3 <artifactId>spring-web</artifactId> 4 <version>${spring.version}</version> 5 </dependency> 6 <dependency> 7 <groupId>org.springframework</groupId> 8 <artifactId>spring-oxm</artifactId> 9 <version>${spring.version}</version> 10 </dependency> 11 <dependency> 12 <groupId>org.springframework</groupId> 13 <artifactId>spring-tx</artifactId> 14 <version>${spring.version}</version> 15 </dependency> 16 <dependency> 17 <groupId>org.springframework</groupId> 18 <artifactId>spring-aop</artifactId> 19 <version>${spring.version}</version> 20 </dependency> 21 <dependency> 22 <groupId>org.springframework</groupId> 23 <artifactId>spring-orm</artifactId> 24 <version>${spring.version}</version> 25 </dependency> 26 <dependency> 27 <groupId>org.springframework</groupId> 28 <artifactId>spring-beans</artifactId> 29 <version>${spring.version}</version> 30 </dependency> 31 <dependency> 32 <groupId>org.springframework</groupId> 33 <artifactId>spring-context-support</artifactId> 34 <version>${spring.version}</version> 35 </dependency> 36 <dependency> 37 <groupId>org.springframework</groupId> 38 <artifactId>spring-aspects</artifactId> 39 <version>${spring.version}</version> 40 </dependency> 41 <dependency> 42 <groupId>org.springframework</groupId> 43 <artifactId>spring-test</artifactId> 44 <version>${spring.version}</version> 45 </dependency>
五：开始创建MVC目录
1.原目录
2.在main节点下新建java和resource
在main上右键后，使用New Folder新建。
3.设置java与resource类型
4.创建如下java项目目录
只需要新建package就可以了。
action：存放Controller
dao：sql对应的接口
mapper：sql的xml文件
model：数据库实体类
service：就是service了
5.创建resource下的文件
先新建一个config目录，以及ssm需要的三个配置文件。
注意的是config不是package，是Directory。
spring的配置文件applicationContext.xml
spring MVC的配置文件springmvc-servlet.xml
数据库链接的配置文件jdbc.properties
六：配置文件以及web.xml的内容
1.applicationContext.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns="http://www.springframework.org/schema/beans" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans.xsd 8 http://www.springframework.org/schema/aop 9 http://www.springframework.org/schema/aop/spring-aop.xsd 10 http://www.springframework.org/schema/context 11 http://www.springframework.org/schema/context/spring-context.xsd 12 http://www.springframework.org/schema/tx 13 http://www.springframework.org/schema/tx/spring-tx.xsd 14 http://www.springframework.org/schema/cache 15 http://www.springframework.org/schema/cache/spring-cache.xsd"> 16 17 <!-- 自动扫描 --> 18 <context:component-scan base-package="service,dao,action"/> 19 <!-- 引入外置文件 --> 20 <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 21 <property name="location" value="classpath:/config/jdbc.properties"/> 22 <!--这个配置告诉spring，当某个placeholder无法找到时，先不要报错，并尝试用另一个PropertyPlaceholderConfigurer来设置placeholder的值。--> 23 <property name="ignoreUnresolvablePlaceholders" value="true" /> 24 </bean> 25 26 <!--数据库连接池配置--> 27 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 28 <property name="driverClassName" value="${jdbc.driver}"/> 29 <property name="url" value="${jdbc.url}"/> 30 <property name="username" value="${jdbc.username}"/> 31 <property name="password" value="${jdbc.password}"/> 32 </bean> 33 34 <bean name="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 35 <property name="dataSource" ref="dataSource"/> 36 <property name="mapperLocations" value="classpath:/mapper/*.xml"/> 37 </bean> 38 39 <!-- 40 Mybatis-Spring为我们提供了一个实现了SqlSession接口的SqlSessionTemplate类，它是线程安全的，可以被多个Dao同时使用。 41 同时它还跟Spring的事务进行了关联，确保当前被使用的SqlSession是一个已经和Spring的事务进行绑定了的。 42 而且它还可以自己管理Session的提交和关闭。当使用了Spring的事务管理机制后，SqlSession还可以跟着Spring的事务一起提交和回滚。 43 --> 44 <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"> 45 <constructor-arg index="0" ref="sqlSessionFactory"/> 46 </bean> 47 48 </beans>
2.springmvc-servlet.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" 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.xsd 8 http://www.springframework.org/schema/context 9 http://www.springframework.org/schema/context/spring-context-4.3.xsd 10 http://www.springframework.org/schema/mvc 11 http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd"> 12 13 <!-- 自动扫描包，实现支持注解的IOC --> 14 <context:component-scan base-package="action" /> 15 16 <!-- Spring MVC不处理静态资源 --> 17 <mvc:default-servlet-handler /> 18 19 <!-- 支持mvc注解驱动 --> 20 <mvc:annotation-driven /> 21 22 <!-- 视图解析器 --> 23 <bean 24 class="org.springframework.web.servlet.view.InternalResourceViewResolver" 25 id="internalResourceViewResolver"> 26 <!-- 前缀 --> 27 <property name="prefix" value="/" /> 28 <!-- 后缀 --> 29 <property name="suffix" value=".jsp" /> 30 </bean> 31 32 </beans>
3.jdbc.properties
1 jdbc.driver=com.mysql.jdbc.Driver 2 jdbc.url=jdbc:mysql://127.0.0.1:3308/test?characterEncoding=utf8&useSSL=false&serverTimezone=GMT 3 jdbc.username=root 4 jdbc.password=123456
4.web.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://java.sun.com/xml/ns/javaee" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 5 id="WebApp_ID" version="3.0"> 6 7 <welcome-file-list> 8 <welcome-file>index.jsp</welcome-file> 9 </welcome-file-list> 10 11 <!-- Spring容器启动监听器 --> 12 <listener> 13 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 14 </listener> 15 <context-param> 16 <param-name>contextConfigLocation</param-name> 17 <param-value>classpath*:config/applicationContext.xml</param-value> 18 </context-param> 19 20 <servlet> 21 <servlet-name>springmvc</servlet-name> 22 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 23 <init-param> 24 <!--Spring mvc配置文件路径 --> 25 <param-name>contextConfigLocation</param-name> 26 <param-value>classpath*:config/springmvc-servlet.xml</param-value> 27 </init-param> 28 <load-on-startup>1</load-on-startup> 29 </servlet> 30 <servlet-mapping> 31 <servlet-name>springmvc</servlet-name> 32 <url-pattern>/</url-pattern> 33 </servlet-mapping> 34 35 <!--编码过滤器 --> 36 <filter> 37 <filter-name>characterEncodingFilter</filter-name> 38 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 39 <init-param> 40 <param-name>encoding</param-name> 41 <param-value>UTF-8</param-value> 42 </init-param> 43 <init-param> 44 <param-name>forceEncoding</param-name> 45 <param-value>true</param-value> 46 </init-param> 47 </filter> 48 <filter-mapping> 49 <filter-name>characterEncodingFilter</filter-name> 50 <url-pattern>/*</url-pattern> 51 </filter-mapping> 52 53 <context-param> 54 <param-name>spring.profiles.active</param-name> 55 <param-value>dev</param-value> 56 </context-param> 57 <context-param> 58 <param-name>spring.profiles.default</param-name> 59 <param-value>dev</param-value> 60 </context-param> 61 <context-param> 62 <param-name>spring.liveBeansView.mbeanDomain</param-name> 63 <param-value>dev</param-value> 64 </context-param> 65 66 </web-app>
七：对应关系（拷贝）
1.对应关系理解
八：测试程序
1.大纲
2.新建数据库
sql如下：
1 CREATE TABLE 2 student 3 ( 4 id INT(1), 5 name VARCHAR(20), 6 sex TINYINT(1), 7 address VARCHAR(50) 8 )
插入数据：
INSERT INTO student VALUES ('1', 'tom', '1', '1');
3.运行
输入网址：
http://localhost:8080/Hello/SayHello
4.效果
以后再做解析。
九：Java区域的程序
1.Student.java
几个字段的domain。
1 package model; 2 3 import java.io.Serializable; 4 5 public class Student implements Serializable { 6 private static final long serialVersionUID = 1L; 7 8 private int id; 9 private String name; 10 private boolean sex; 11 private String address; 12 13 public void setId(int id) { 14 this.id = id; 15 } 16 17 public void setName(String name) { 18 this.name = name; 19 } 20 21 public void setSex(boolean sex) { 22 this.sex = sex; 23 } 24 25 public void setAddress(String address) { 26 this.address = address; 27 } 28 29 public int getId() { 30 return id; 31 } 32 33 public String getName() { 34 return name; 35 } 36 37 public boolean isSex() { 38 return sex; 39 } 40 41 public String getAddress() { 42 return address; 43 } 44 45 @Override 46 public String toString() { 47 return "Student{" + 48 "id=" + id + 49 ", name='" + name + '\'' + 50 ", sex=" + sex + 51 ", address='" + address + '\'' + 52 '}'; 53 } 54 }
2.StudentDao.java
这个没有用到，dao的处理在service中处理了
1 package dao; 2 3 import model.Student; 4 5 public interface StudentDao { 6 /** 方法名对应Mapper中方法名 */ 7 // public Student getStudent(int id); 8 }
3.StudentService.java
1 package service; 2 3 import model.Student; 4 import org.mybatis.spring.SqlSessionTemplate; 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.stereotype.Controller; 7 8 @Controller 9 public class StudentService { 10 /** 11 *sqlSessionTemplate模板提供了sqlsession 12 */ 13 @Autowired 14 private SqlSessionTemplate sqlSessionTemplate; 15 public Student getStudent(int id) { 16 Student student = sqlSessionTemplate.selectOne("dao.StudentDao.getStudent", id); 17 return student; 18 } 19 }
4.HelloWorld.java
1 package action; 2 3 import org.springframework.beans.factory.annotation.Autowired; 4 import org.springframework.stereotype.Controller; 5 import org.springframework.ui.Model; 6 import org.springframework.web.bind.annotation.RequestMapping; 7 import service.StudentService; 8 9 @Controller 10 @RequestMapping("/Hello") 11 public class HelloWorld { 12 @Autowired 13 private StudentService studentService; 14 15 @RequestMapping("/SayHello") 16 public String SayHello(Model model) { 17 String student = studentService.getStudent(1).toString(); 18 System.out.println(student); 19 model.addAttribute("message", student); 20 // 对应页面名 21 return "/hello"; 22 } 23 }
5.StudentMapper.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE mapper 3 PUBLIC "-//mybatis.org//DTD mapper 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> 5 <mapper namespace="dao.StudentDao"> 6 7 <select id="getStudent" parameterType="int" resultType="model.Student"> 8 SELECT * 9 FROM student 10 WHERE id = #{id} 11 </select> 12 13 </mapper>
十：在过程中遇到的几个奇葩的问题
1.缺少common-pool
