所谓的SSM 其实就是Spring MVC下整合mybatis。
具体的定义网络上都有，很详细。
这里只说项目的搭建步骤。
第一步
新建maven工程
工程目录如下：
配置pom.xml文件，引入所需的jar包
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>BookMaven</groupId> <artifactId>BookMaven</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <!-- spring版本号 --> <spring.version>4.0.2.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.2.6</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.7.7</slf4j.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <!-- 表示开发的时候引入，发布的时候不会加载此包 --> <scope>test</scope> </dependency> <!-- spring核心包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>4.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>4.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.0.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.0.2.RELEASE</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.6</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <!-- JSTL标签类 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- 格式化对象，方便输出日志 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.7</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.7</version> </dependency> <!-- log end --> <!-- 映入JSON --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 上传组件包 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.9</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.7.4</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> </plugins> </build> </project>
第二步 Spring MVC和mybatis的整合
springmvc.xml文件
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "> <!-- 可以扫描controller、service、... 这里让扫描controller，指定controller的包 --> <context:component-scan base-package="com.book.controller"></context:component-scan> <mvc:annotation-driven ></mvc:annotation-driven> <!-- 视图解析器 解析jsp解析，默认使用jstl标签，classpath下的得有jstl的包 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 配置jsp路径的前缀 --> <property name="prefix" value="/"/> <!-- 配置jsp路径的后缀 --> <property name="suffix" value=".jsp"/> </bean> <!-- 文件上传 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 设置上传文件的最大尺寸为5MB --> <property name="maxUploadSize"> <value>5242880</value> </property> </bean> <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <property name="exceptionMappings"> <props> <!-- 遇到MaxUploadSizeExceededException异常时，自动跳转到/WEB-INF/jsp/error_fileupload.jsp页面 --> <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">error_fileupload</prop> </props> </property> </bean> <!--拦截器 --> </beans>

mybatis的全局配置文件
sqlMapConfig.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- 全局setting配置，根据需要添加 --> <!-- 配置别名 --> <typeAliases> <!-- 批量扫描别名 --> <package name="com.book.model"/> </typeAliases> <!-- 配置mapper 由于使用spring和mybatis的整合包进行mapper扫描，这里不需要配置了。 必须遵循：mapper.xml和mapper.java文件同名且在一个目录 --> <!-- <mappers> </mappers> --> </configuration>
mysql数据库的配置文件
db.properties文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/booktest
jdbc.username=root
jdbc.password=root
附：配置文件目录：
第三步、开始写代码
Java 目录：
model层：
Person.java
public class Person { private Integer id; private String name; private Integer age; 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 Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } public Person(){ super(); } @Override public String toString() { return "Person [Id=" + id + ", Name=" + name + ", age=" + age + "]"; } }
service层:
PersonService.java
public interface PersonService { public Person find(int id); public List<Person> FindAll(); }
PersonServiceImpl.java
@Service public class PersonServiceImpl implements PersonService{ @Autowired private PersonMapper personDao; public void setUserDao(PersonMapper personDao) { this.personDao = personDao; } public Person find(int id) { // TODO Auto-generated method stub return personDao.find(id); } public List<Person> FindAll() { // TODO Auto-generated method stub return personDao.FindAll(); } }
dao层
PersonMapper.java
public interface PersonMapper { public Person find(int id); public List<Person> FindAll(); }
PersonMapper.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.book.dao.PersonMapper"> <resultMap type="com.book.model.Person" id="PersonMap" > <id column="id" property="id"/> <result column="name" property="name"/> <result column="age" property="age"/> </resultMap> <select id="find" parameterType="int" resultMap="PersonMap"> <![CDATA[ SELECT * FROM person WHERE id = LOWER(#{id}) ]]> </select> <select id="FindAll" resultMap="PersonMap"> <![CDATA[ SELECT * FROM person ]]> </select> </mapper>
controller层：
PersonController.java
@Controller public class PersonController { @Autowired private PersonService personService; public void setUserService(PersonService personService) { this.personService = personService; } @RequestMapping("/person") public ModelAndView person(){ Person person =personService.find(1); String str= person.toString(); return new ModelAndView("message","str",str); } @RequestMapping("/personlist") public ModelAndView personlist(){ List<Person> person= new ArrayList<Person>(); person=personService.FindAll(); JSONObject json=new JSONObject(); json.put("person", person); return new ModelAndView("message","str",json); } }
前端页面：
