前言

ssm整合是学习java开发过程中比较重要的学习点，通过spring框架整合springMVC与mybatis

使用工具：IDEA

一、构建项目结构

1. 新建一个项目

2. 完善目录结构

在main下创建java和resources 并分别标记为源码包和资源包

注意：在resources下创建两个xml文件，文件名分别为：applicationContext.xml springmvc.xml WEB-INF下创建views文件夹

二、配置文件

1. 导入依赖文件

在pom.xml中添加依赖

内容如下：

<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>  <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>  <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>${slf4j.version}</version> </dependency>  <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${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> </dependencies>

引入：完成后查看外部库说明依赖添加成功

2. web.xml编写

代码如下（示例）：

<!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 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"> <display-name>Archetype Created Web Application</display-name> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <filter> <filter-name>encodingFilter</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>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>  <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>  <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> </web-app>

3.编写applicationContext.xml

提醒：请按自己的情况修改配置文件中的包名（注释中已标出需要注意的地方）

内容如下：

<?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"> <context:component-scan base-package="com.kaier">   <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql:///ssm_test2" />  <property name="username" value="root" /> <property name="password" value="root" /> </bean>  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> </bean>  <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.kaier.dao"/> </bean> </beans>

4. 编写springmvc.xml

提醒：请按自己的情况修改配置文件中的包名（注释中已标出需要注意的地方）代码如下（示例）：

<?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">  <context:component-scan base-package="com.kaier"/>  <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">  <property name="prefix" value="/WEB-INF/views/"></property>  <property name="suffix" value=".html"></property> </bean>  <mvc:default-servlet-handler/>  <mvc:annotation-driven/> </beans>

三、编写测试环境

1. 数据库创建

代码如下（示例）：

CREATE DATABASE ssm_test2; USE ssm_test2; CREATE TABLE account( id INT PRIMARY KEY AUTO_INCREMENT, NAME VARCHAR(20), age INT );

2. 编写实体类

代码如下（示例）：

import java.io.Serializable; public class Account implements Serializable{ 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; } @Override public String toString() { return "Account{" + "id=" + id + ", name='" + name + '\'' + ", age=" + age + '}'; } }

3. 编写持久层接口

在dao下创建AccountDao接口代码如下（示例）：

@Repository public interface AccountDao { @Insert(value="insert into account (name,age) values (#{name},#{age})") public void saveAccount(Account account); @Select("select * from account") public List<Account> findAll(); }

4. 编写业务层接口及其实现类

1. 接口部分（AccountService）代码如下（示例）：

public interface AccountService { public void saveAccount(Account account); public List<Account> findAll(); }

2. 接口实现类部分（AccountServiceImpl）代码如下（示例）：

@Service("accountService") public class AccountServiceImpl implements AccountService { @Autowired private AccountDao accountDao; public void saveAccount(Account account) { } public List<Account> findAll() { System.out.println("-----//业务层//----"); return accountDao.findAll(); } }

5.编写controller

在controller文件夹下创建AccountController类代码如下（示例）：

@Controller @RequestMapping("/account") public class AccountController { @Autowired private AccountService accoutService; /** * 查询所有的数据 * @return */ @RequestMapping("/findAll") public String findAll() { System.out.println("表现层..."); List<Account> list = accoutService.findAll(); for (Account account : list) { System.out.println(account); } return "list"; } }

提醒：粘贴时不要覆盖自己生成的package ;粘贴代码后需要自己导包哦（快捷键alt+enter）

6.编写前端html

注意不是jsp文件，需将默认生成的jsp改为html

在index.html中添加查询a标签 <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <body> <a href="account/findAll">查询用户</a> </body> </html> 在views文件夹下创建list.html(获取反馈) <html> <body> <h2>Hello World!</h2> </body> </html>

四、运行测试

1. 部署项目

![在这里插入图片描述](https://img-blog.csdnimg.cn/2020090413561034.png#pic_left)

2. 运行项目

控制台输出：浏览器：点击查询后
