一、SSM框架的整合

1.创建数据库表

CREATE DATABASE ssm;
USE ssm; 
CREATE TABLE account( id INT PRIMARY KEY AUTO_INCREMENT, NAME VARCHAR(20),  money DOUBLE 
)

2.创建maven项目，导入pom依赖

<properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><maven.compiler.source>1.7</maven.compiler.source><maven.compiler.target>1.7</maven.compiler.target><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>${spring.version}</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>compile</scope></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${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><dependency><groupId>c3p0</groupId><artifactId>c3p0</artifactId><version>0.9.1.2</version><type>jar</type><scope>compile</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.12</version><scope>compile</scope></dependency>

3.分别编写pojo实体类、dao接口、service接口和实现类

pojo实体类

package com.bianyiit.pojo;import lombok.Data;@Data
public class Account {private Integer id;private String name;private Double money;
}

dao接口

package com.bianyiit.dao;import com.bianyiit.pojo.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;import java.util.List;@Repository
public interface AccountDao {/*查询所有用户*/@Select("select * from account")List<Account> findAll();/*新增用户*/@Insert("insert into account(name,money) values(#{name},#{money})")void saveAccount(Account account);
}

service接口

package com.bianyiit.service;import com.bianyiit.pojo.Account;import java.util.List;public interface AccountService {List<Account> findAll();void saveAccount(Account account);
}

service实现类

package com.bianyiit.service.impl;import com.bianyiit.dao.AccountDao;
import com.bianyiit.pojo.Account;
import com.bianyiit.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;@Service
public class AccountServiceImpl implements AccountService {@Autowiredprivate AccountDao accountDao;@Overridepublic List<Account> findAll() {return accountDao.findAll();}@Overridepublic void saveAccount(Account account) {}
}

4.搭建spring环境，在resources下面添加一个applicationContext.xml

<?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"><!--开启包扫描--><context:component-scan base-package="com.bianyiit"><!--配置哪些注解不扫描--><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><!--配置连接池数据源--><bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="com.mysql.jdbc.Driver" /><property name="url" value="jdbc:mysql:///ssm" /><property name="username" value="root" /><property name="password" value="123" /></bean><!--配置平台事务管理器--><bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"></property></bean><!--使用aop增强开启声明式事务--><tx:advice id="txAdvice" transaction-manager="dataSourceTransactionManager"><tx:attributes><!--只读事务--><tx:method name="findAll" read-only="true"/><tx:method name="*" isolation="DEFAULT"></tx:method></tx:attributes></tx:advice><aop:config><aop:advisor advice-ref="txAdvice" pointcut="execution(* com.bianyiit.service.impl.AccountServiceImpl.saveAccount(..))"></aop:advisor></aop:config><!--spring整合mybatis只需要配置数据源、sqlsession工厂、配置dao扫描--><!-- 配置SqlSession的工厂 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!--通过连接池构建Session工厂--><property name="dataSource" ref="dataSource" /></bean><!-- 配置扫描dao的包 --><bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.bianyiit.dao"/></bean>
</beans>

5.搭建springmvc环境，在resources下创建springmvc.xml配置文件

<?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:mvc="http://www.springframework.org/schema/mvc"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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"><!-- 扫描controller的注解，别的不扫描 --><context:component-scan base-package="com.bianyiit"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><!-- 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 location="/css/" mapping="/css/**" /><mvc:resources location="/images/" mapping="/images/**" /><mvc:resources location="/js/" mapping="/js/**" /><!-- 开启对SpringMVC注解的支持 --><mvc:annotation-driven/>
</beans>

6.在webapp/WEB-INF/web.xml中配置前端控制器，初始化Spring的IOC容器

<!DOCTYPE web-app PUBLIC"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN""http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app><display-name>Archetype Created Web Application</display-name><!-- 配置加载类路径的配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><!-- 配置Spring的监听器：ContextLoaderListener监听器的作用就是启动Web容器时，自动装配ApplicationContext的配置信息--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 配置前端控制器：服务器启动必须加载，需要加载springmvc.xml配置文件 --><servlet><servlet-name>dispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 配置初始化参数，创建完DispatcherServlet对象，加载springmvc.xml配置文件 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><!-- 服务器启动的时候，让DispatcherServlet对象创建 --><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>dispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping>
</web-app>

7.在web层创建AccountController

package com.bianyiit.web;import com.bianyiit.pojo.Account;
import com.bianyiit.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;import java.util.List;@Controller
@RequestMapping("/account")
public class AccountController {@Autowiredprivate AccountService accountService;@RequestMapping("/findAll")public String findAll(Model model){List<Account> list = accountService.findAll();model.addAttribute("list",list);return "list";}
}

8.在webapp目录下创建index.jsp，记住要开启对EL表达式的支持

<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<html>
<head><title>Title</title>
</head>
<body><a href="/account/findAll">查询所有用户信息</a>
</body>
</html>

9.在webapp目录下创建一个pages目录，在该目录下创建list.jsp界面

<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head><title>Title</title>
</head>
<body><c:forEach var="list" items="${list}">${list.id}${list.name}${list.money}<br></c:forEach>
</body>
</html>

10.在tomcat上部署该SSM框架项目，查询出所有数据并显示在list.jsp界面中
