基于XML+注解方式的SSM整合（简单），
一、搭建整合环境
1. 整合的思路
1. 先搭建整合的环境
2. 先把Spring的配置搭建完成
3. 再使用Spring整合SpringMVC框架
4. 最后使用Spring整合MyBatis框架
框架大致结构图：
语句：
create database ssm; use ssm; create table account( id int primary key auto_increment, name varchar(20), money double );
3. 创建maven的工程并导入相应依赖
<dependencies> <!--Junit--> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <!--Junit整合Spring--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>5.2.0.RELEASE</version> </dependency> <!--数据库驱动--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.46</version> </dependency> <!--数据库连接池--> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.3</version> </dependency> <!--servlet jsp--> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.2</version> </dependency> <!--mybatis--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.5.3</version> </dependency> <!--MyBatis整合spring--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>2.0.3</version> </dependency> <!--spring--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.2.0.RELEASE</version> </dependency> <!--spring 织入--> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.4</version> </dependency> <!--springjdbc--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>5.2.0.RELEASE</version> </dependency> <!--jstl--> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!--spring事物--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>5.2.0.RELEASE</version> </dependency> <!--lombok--> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.10</version> </dependency> <!--日志包--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.28</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.28</version> </dependency> </dependencies>
如果出现静态资源导出问题添加下面代码：
<build> <!--静态资源导出问题--> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> </resources> </build>
二、框架代码的编写
创建jdbcConfig.properties文件：
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssm?useSSL=true jdbc.username=root jdbc.password=123456
创建applicationContext.xml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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" 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/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!--开启注解的扫描,只处理业务层和dao层，controller不需要spring去处理--> <context:component-scan base-package="com.wsl"> <!--配置哪些不扫描--> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:jdbcConfig.properties"/> <!-- 配置数据源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${jdbc.driver}"></property> <property name="jdbcUrl" value="${jdbc.url}"></property> <property name="user" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!-- 配置 MyBatis 的 Session 工厂 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 数据库连接池 --> <property name="dataSource" ref="dataSource"/> <!-- 加载 mybatis 的全局配置文件 --> <property name="configLocation" value="classpath:mybatis-config.xml"/> </bean> <!-- 配置 Mapper 扫描器 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.wsl.mapper"/> </bean> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 配置事务的通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="*" propagation="REQUIRED" read-only="false"/> <tx:method name="find*" propagation="SUPPORTS" read-only="true"/> </tx:attributes> </tx:advice> <!-- 配置 aop --> <aop:config> <!-- 配置切入点表达式 --> <aop:pointcut id="pt1" expression="execution(* com.wsl.service.impl.*.*(..))"/> <!-- 建立通知和切入点表达式的关系 --> <aop:advisor advice-ref="txAdvice" pointcut-ref="pt1"/> </aop:config> </beans>
创建springmvc.xml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"> <!--开启注解扫描--> <context:component-scan base-package="com.wsl"> <!--只扫描SpringMVC注解--> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!--配置视图解析器--> <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean> <!--过滤静态资源--> <mvc:resources mapping="/js/**" location="/js/"/> <mvc:resources mapping="/images/**" location="/images/"/> <mvc:resources mapping="/css/**" location="/css/"/> <!--开启SpringMVC的注解支持--> <mvc:annotation-driven></mvc:annotation-driven> </beans>
创建mybatis-config.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> <!-- <properties resource="jdbcConfig.properties"></properties>--> <!-- 类型别名 --> <typeAliases> <package name="com.wsl.pojo"/> </typeAliases> <!-- <environments default="mysql"> <environment id="mysql"> <transactionManager type="JDBC"></transactionManager> <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>--> <!--mapper映射位置--> <!--<mappers> <package name="com.wsl.mapper"/> </mappers>--> </configuration>
创建log4j.properties文件：
# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# MyBatis logging configuration...
log4j.logger.com.wsl.mapper=DEBUG
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
在web.xml文件中配置：
<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"> <!--配置Servlet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> <!--启动服务器，创建Servlet--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--配置中文乱码过滤器--> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <!--编码值--> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <!--拦截所有--> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置Spring的监听器,用于启动服务时加载容器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 手动指定 spring 配置文件位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> </web-app>
实体类Account：
@Data @AllArgsConstructor @NoArgsConstructor public class Account implements Serializable { private int id; private String name; private double money; }
Mapper接口AccountMapper：
public interface AccountMapper { /** * @return accounts * 查询account集合 */ List<Account> selectAll(); /** * @return account * 查询单个数据 */ Account selectOne(); /** * @param account * 添加数据 */ void add(Account account); /** * @param account * 修改 */ void update(Account account); /** * @param id * 删除 */ void delete(int id); }
AccountMapper.xml文件（这里文件位置必须在mapper接口同一包下）：
<?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.wsl.mapper.AccountMapper"> <select id="selectAll" resultType="account"> select * from ssm.account </select> <select id="selectOne" resultType="account" parameterType="Integer"> select * from ssm.account where id = #{id} </select> <insert id="add" parameterType="account"> insert into ssm.account(name, money) values (#{name},#{money}) </insert> <update id="update" parameterType="account"> update ssm.account set name = #{name},money = #{money} where id = #{id} </update> <delete id="delete" parameterType="Integer"> delete from ssm.account where id = #{id} </delete> </mapper>
AccountService接口：
public interface AccountService { /** * @return Account * 查询所有account数据 */ public List<Account> findAll(); /** * @param id * @return Account * 根据id查询Account单个数据 */ public Account findAccById(int id); /** * 添加 */ public void add(Account account); /** * @param account * 修改 */ public void update(Account account); /** * @param id * 删除 */ public void delete(int id); }
AccountServiceImpl实现类：
@Service("accountService")
public class AccountServiceImpl implements AccountService {
@Autowired
private AccountMapper accountMapper;
/**
* @return Account
* 查询所有account数据
*/
@Override
public List<Account> findAll() {
System.out.println("业务成调用查询所有方法");
List<Account> accounts = accountMapper.selectAll();
return accounts;
}
/**
* @param id
* @return Account
* 根据id查询Account单个数据
*/
@Override
public Account findAccById(int id) {
Account account = accountMapper.selectOne();
return account;
}
/**
* 添加
*
* @param account
*/
@Override
public void add(Account account) {
accountMapper.add(account);
}
/**
* @param account 修改
*/
@Override
public void update(Account account) {
accountMapper.update(account);
}
/**
* @param id 删除
*/
@Override
public void delete(int id) {
accountMapper.delete(id);
}
}
AccountController控制类：
@Controller @RequestMapping("account") public class AccountController { @Autowired private AccountService accountService; @RequestMapping("findAll") public String findAll(Model model){ List<Account> accounts = accountService.findAll(); model.addAttribute("accounts",accounts); return "list"; } @RequestMapping("saveAccount") public String findAll(Account account){ accountService.add(account); return "redirect:findAll"; }
index.jsp页面：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1><a href="account/findAll">测试</a></h1>
<hr/>
<form action="account/saveAccount" method="post">
账户名称：<input type="text" name="name"/><br/>
账户金额：<input type="text" name="money"><br/>
<input type="submit" value=" 保存 "/></form>
</body>
</html>
list.jsp页面：
<%@ 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>
<h1>跳转成功</h1>
<table border="1" width="300px">
<tr>
<th>编号</th>
<th>账户名称</th>
<th>账户金额</th>
</tr>
<c:forEach items="${accounts}" var="account" varStatus="vs">
<tr>
<td>${vs.count}</td>
<td>${account.name }</td>
<td>${account.money }</td>
</tr>
</c:forEach>
</table>
</body>
</html>
运行项目进行测试：
测试结果：
以上就是SSM框架的简单整合和使用。
注：这只是我作为个人搭建SSM框架笔记，并不详细只是作为快速搭建，如果问题可以指出勿喷，毕竟我也只是一个小菜鸟。
