对于ssm框架网上有很多,这里只是自己为大家提供的一个ssm整合框架参考分享,这个前提是基于maven的管理工具写的,
一 创建Maven项目具体步骤如下:
二 配置文件
2.1 配置mybatis-config.xml
2.2 配置mapper.xml
2.3 配置jdbc.properties
2.4 配置applicationContext.xml
2.5 配置springmvc-servlet.xml
2.6 配置web.xml
2.7 配置log4j.properties
2.8 引入依赖
三 测试
3.1 创建java文件
3.1.1 UserController类
3.1.2 User实体类
3.1.3 UserService接口
3.1.4 UserServiceImpl实现类
3.1.5 UserMapper类
3.2 创建MySql数据库表
3.3 创建users.jsp文件
3.4 结果
==============================================================================
1.设计数据库表如下:
/* Date: 2019-03-11 23:19:10 */ SET FOREIGN_KEY_CHECKS=0; -- ---------------------------- -- Table structure for tb_user -- ---------------------------- DROP TABLE IF EXISTS `tb_user`; CREATE TABLE `tb_user` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `user_name` varchar(100) DEFAULT NULL COMMENT '用户名', `password` varchar(100) DEFAULT NULL COMMENT '密码', `name` varchar(100) DEFAULT NULL COMMENT '姓名', `age` int(10) DEFAULT NULL COMMENT '年龄', `sex` tinyint(1) DEFAULT NULL COMMENT '性别,1男性,2女性', `birthday` date DEFAULT NULL COMMENT '出生日期', `created` datetime DEFAULT NULL COMMENT '创建时间', `updated` datetime DEFAULT NULL COMMENT '更新时间', PRIMARY KEY (`id`), UNIQUE KEY `username` (`user_name`) ) ENGINE=InnoDB AUTO_INCREMENT=27 DEFAULT CHARSET=utf8; INSERT INTO `tb_user` VALUES (1, 'zhangsan', '123456', '张三', 30, 1, '1984-8-8', '2014-9-19 16:56:04', '2014-9-21 11:24:59'); INSERT INTO `tb_user` VALUES (2, 'lisi', '123456', '李四', 21, 2, '1991-1-1', '2014-9-19 16:56:04', '2014-9-19 16:56:04'); INSERT INTO `tb_user` VALUES (3, 'wangwu', '123456', '王五', 22, 2, '1989-1-1', '2014-9-19 16:56:04', '2014-9-19 16:56:04'); INSERT INTO `tb_user` VALUES (4, 'zhangwei', '123456', '张伟', 20, 1, '1988-9-1', '2014-9-19 16:56:04', '2014-9-19 16:56:04'); INSERT INTO `tb_user` VALUES (5, 'lina', '123456', '李娜', 28, 1, '1985-1-1', '2014-9-19 16:56:04', '2014-9-19 16:56:04'); INSERT INTO `tb_user` VALUES (6, 'lilei', '123456', '李磊', 23, 1, '1988-8-8', '2014-9-20 11:41:15', '2014-9-20 11:41:15'); INSERT INTO `tb_user` VALUES (8, 'xiaofeng', '123456', '萧峰', 30, 1, '2018-6-25', '2018-6-25 18:42:25', '2018-6-25 18:42:25'); INSERT INTO `tb_user` VALUES (12, 'zhendeshuai', '565656', '吴彦祖', 26, 1, '2018-6-26', '2018-6-26 14:55:59', '2018-6-26 15:12:12'); INSERT INTO `tb_user` VALUES (14, 'jiumozhi', '123456', '鸠摩智', 30, 1, '2018-6-26', '2018-6-26 23:53:15', '2018-6-26 23:53:15'); INSERT INTO `tb_user` VALUES (21, 'zhangsan1234', '12345', '杰克', 20, 1, '2000-1-1', '2018-7-7 21:50:26', '2018-7-7 21:50:26'); INSERT INTO `tb_user` VALUES (22, 'zhangsanqwe1', '123455', '张三', 30, 1, '1999-2-25', '2018-7-7 21:51:20', '2018-7-7 21:51:20'); INSERT INTO `tb_user` VALUES (25, 'qianjiu', '123456', '钱九', 30, 1, '1989-1-1', '2018-7-7 21:51:20', '2018-7-7 21:51:20'); INSERT INTO `tb_user` VALUES (26, 'zhaoniu', '123456', '赵牛', 28, 1, '1989-1-1', '2018-7-7 21:51:20', '2018-7-7 21:51:20');
2 创建一个ssmDemo项目(项目名称可以自定义),如图所示:
创建好之后如下图所示:
项目会报错,不用急,为什么呢?因为这是一个不完整的maven项目,缺少web.xml。
右键点击项目,如下操作,会自动补全web.xml文件
3,向ssmzh项目中的pom.xml导入spring-springmvc-mybatis整合所需要的依赖,具体依赖如下:
<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>com.agu</groupId> <artifactId>SSMDemo</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <dependencies> <!--spring--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.3.13.RELEASE</version> </dependency> <!--配置webmvc--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.13.RELEASE</version> </dependency> <!--配置spring jdbc,用来加载DataSourceTransactionManager--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.13.RELEASE</version> </dependency> <!--配置切面的jar包--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.3.13.RELEASE</version> </dependency> <!--mybatis,用来加载SqlSessionFactoryBean和MapperScannerConfigurer--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!--数据库驱动包--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.32</version> </dependency> <!--日志文件--> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.22</version> </dependency> <!--json处理工具包--> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.0</version> </dependency> <!-- 连接池,用来加载DruidDataSource--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.9</version> </dependency> <!--javaScript标签库--> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> </dependency> </dependencies> <build> <plugins> <!-- 配置Tomcat插件 --> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <port>8080</port> <path>/</path> </configuration> </plugin> </plugins> </build> </project>
4,配置spring.xml(企业常用applicationContext.xml命名表示是spring的配置,我这里命名为spring.xml)

7,springmvc.xml配置如下:
<?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:p="http://www.springframework.org/schema/p" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 配置推荐使用注解驱动,会默认的加载上面的两个 HandlerMapping, HandlerAdapter --> <mvc:annotation-driven /> <!-- 开启springmvc注解扫描 --> <context:component-scan base-package="cn.usermanage.controller"></context:component-scan> <!-- 这个是excelView的加载,原生态ssm不需要,所以这里是可以省略的 --> <!-- <bean name="excelView" class="cn.usermanage.view.UserExcelView"></bean> --> <!-- 视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 前缀,这里是请求的路径文件 --> <property name="prefix" value="/WEB-INF/views/"></property> <!-- 后缀 ,支持.jsp的请求--> <property name="suffix" value=".jsp"></property> </bean> <!-- 以上是原生态的ssm配置 --> <!-- 配置第二个视图解析器 --> <!-- <bean class="org.springframework.web.servlet.view.BeanNameViewResolver"> <property name="order" value="1"></property> </bean> --> <!-- 定义文件上传解析器 --> <!-- <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 设定默认编码 <property name="defaultEncoding" value="UTF-8"></property> 设定文件上传的最大值5MB,5*1024*1024 <property name="maxUploadSize" value="5242880"></property> </bean> --> <!-- 解决静态资源被拦截的问题 --> <!-- <mvc:default-servlet-handler/> --> </beans>

结构图所下:
启动项目输入:http://www.localhost:8080/SSMDemo/user/list
运行结果如下图:
那么到此:一个完整的spring-springmvc-mybatis的整合框架就搭建好了,也许你觉得很复杂,那么这只是一个框架的开始,这个是必须要会的,不论怎么样,一定要多亲自搭建,一次,两次甚至更多,如果连这个基本框架都觉得难,那么你是否也在想应该放弃了。不管哪个行业都有它的难处,要想获得更高必须比别人付出更多。
