这篇文章给大家介绍如何搭建一个SSM空间，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
整合说明：SSM整合可以使用多种方式，咱们会选择XML + 注解的方式
整合的思路
2.1. 先搭建整合的环境
2.2. 先把Spring的配置搭建完成
2.3. 再使用Spring整合SpringMVC框架
2.4. 最后使用Spring整合MyBatis框架
创建数据库和表结构
3.1创建数据库
create database ssm; create table account( id int primary key auto_increment, name varchar(20), money double );
4.创建maven工程
<properties> <spring.version>5.0.2.RELEASE</spring.version> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.12</log4j.version> <mysql.version>5.1.6</mysql.version> <mybatis.version>3.4.5</mybatis.version> </properties> <dependencies> <!--spring--> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.6.8</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency><dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!--log start--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.0</version> </dependency> <!--连接池--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.10</version></dependency> </dependencies> <build> <finalName>ssm</finalName> <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.2</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> <showWarnings>true</showWarnings> </configuration> </plugin> </plugins> </pluginManagement> </build>
编写实体类，在ssm_domain项目中编写
package com.qcby.entity;
import java.io.Serializable;
public class Account implements Serializable {
// 主键
private int id;
// 账户名称
private String name;
// 账号的金额
private Double money;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Double getMoney() {
return money;
}
public void setMoney(Double money) {
this.money = money;
}
@Override
public String toString() {
return "Account{" +
"id=" + id +
", name='" + name + '\'' +
", money=" + money +
'}';
}
}编写service接口和实现类
package com.qcby.service;
import com.qcby.entity.Account;
import java.util.List;
public interface AccountService {
//查询所有
public List<Account> findAll();
}package com.qcby.service;
import com.qcby.entity.Account;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class AccountServiceImpl implements AccountService {
//查询所有
@Override
public List<Account> findAll() {
System.out.println("业务层：查询所有");
return null;
}
}1. 搭建和测试Spring的开发环境
在ssm_web项目中创建spring.xml的配置文件，编写具体的配置信息。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--开启注解扫描，要扫描的是service--> <context:component-scan base-package="com.qcby.service"/> </beans>
在ssm_web项目中编写测试方法，进行测试
package com.qcby.demo;
import com.qcby.service.AccountService;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestSpring {
@Test
public void run(){
ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring.xml");
AccountService service = ac.getBean(AccountService.class);
service.findAll();
}
}在web.xml中配置DispatcherServlet前端控制器
<!--配置前端控制器--> <servlet> <servlet-name>DispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--加载springmvc.xml配置文件--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <!-- 启动加载--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>DispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
在web.xml中配置DispatcherServlet过滤器解决中文乱码
<!--解决post请求中文乱码的过滤器--> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
创建springmvc.xml的配置文件，编写配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--扫描controller的注解，别的不扫描--> <context:component-scan base-package="com.qcby.controller"/> <!-- 配置视图解析器--> <bean id="ViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!--JSP文件所在的目录--> <property name="prefix" value="/pages/"/> <!--文件的后缀名--> <property name="suffix" value=".jsp"/> </bean> <!--设置静态资源不过滤--> <mvc:resources mapping="/source/css/**" location="/source/css/"/> <mvc:resources mapping="/source/js/**" location="/source/js/"/> <mvc:resources mapping="/source/images/**" location="/source/images/"/> <!--开启springmvc--> <mvc:annotation-driven/> </beans>
测试SpringMVC的框架搭建是否成功
4.1. 编写index.jsp和list.jsp编写，超链接
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> <a href="/account/findAll" rel="external nofollow" rel="external nofollow" >查询所有</a> </body> </html>
4.2. 创建AccountController类，编写方法，进行测试
package com.qcby.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/account")
public class AccountController {
/**
* 查询所有
* @return
*/
@RequestMapping("/findAll")
public ModelAndView findAll(){
System.out.println("表现层：查询所有");
ModelAndView mv = new ModelAndView();
mv.setViewName("suc");
return mv;
}
}目的：在controller中能成功的调用service对象中的方法。
在项目启动的时候，就去加载spring.xml的配置文件，在web.xml中配置
ContextLoaderListener监听器（该监听器只能加载WEB-INF目录下的applicationContext.xml的配置文
件，所以要配置全局的变量加载类路径下的配置文件）。
<!--配置Spring的监听器--> <display-name>Archetype Created Web Application</display-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--配置加载类路径的配置文件--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml</param-value> </context-param>
在controller中注入service对象，调用service对象的方法进行测试
package com.qcby.controller;
import com.qcby.entity.Account;
import com.qcby.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/account")
public class AccountController {
//依赖注入
@Autowired
private AccountService accountService;
/**
* 查询所有
* @return
*/
@RequestMapping("/findAll")
public ModelAndView findAll(){
System.out.println("表现层：查询所有");
//调用service的方法
List<Account> list = accountService.findAll();
ModelAndView mv = new ModelAndView();
mv.setViewName("suc");
return mv;
}
}在web项目中编写SqlMapConfig.xml的配置文件，编写核心配置文件
<?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>
<properties resource="jdbc.properties"></properties>
<!--定义别名-->
<typeAliases>
<!--把com.qcby.entity.User使用user别名来显示，别名user User USER都可以，默认是忽略大写的-->
<!--<typeAlias type="com.qcby.entity.User" alias="user"/>-->
<!--针对com.qcby.entity包下的所有的类，都可以使用当前的类名做为别名-->
<package name="com.qcby.entity"/>
</typeAliases>
<environments default="mysql">
<environment id="mysql">
<!--配置事务的类型，使用本地事务策略-->
<transactionManager type="JDBC"></transactionManager>
<!--是否使用连接池 POOLED表示使用链接池，UNPOOLED表示不使用连接池-->
<dataSource type="POOLED">
<property name="driver" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</dataSource>
</environment>
</environments>
<mappers>
<mapper resource="mapper/AccountDao.xml"></mapper>
</mappers>
</configuration>AccountDao接口
package com.qcby.dao;
import com.qcby.entity.Account;
import java.util.List;
public interface AccountDao {
//查询所有
public List<Account> findAll();
}编写AccountDao.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.qcby.dao.AccountDao"> <select id="findAll" resultType="account"> select * from account </select> </mapper>
编写测试的方法
package com.qcby.demo;
import com.qcby.dao.AccountDao;
import com.qcby.entity.Account;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;
import java.io.IOException;
import java.io.InputStream;
import java.util.List;
public class TestMybatis {
@Test
public void run() throws IOException {
InputStream in = Resources.getResourceAsStream("mybatis.xml");
SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
SqlSession session = factory.openSession();
AccountDao mapper = session.getMapper(AccountDao.class);
List<Account> list = mapper.findAll();
for (Account account : list) {
System.out.println(account);
}
//关闭资源
session.close();
in.close();
}
}目的：把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中
在service中注入dao对象，进行测试
