ssm框架+maven整合实现简单登录
来源：互联网 发布：hyper v linux 不流畅 编辑：程序博客网 时间：2024/06/05 15:55
环境：
eclipse oxygen
jdk1.8
spring4.1（jdk1.8不支持spring3.2，入过要用的话可以把jdk版本换成1.7，我在这里入过坑）
开始开发：
新建一个maven project，然后在pom.xml加入maven依赖
<dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!--打印日志--><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency> <!-- 日志适配器 --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-slf4j-impl</artifactId> <version>2.5</version> </dependency> <!-- 日志实现 --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>2.5</version> </dependency> <!-- aspectj框架包 --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.9</version> <scope>runtime</scope> </dependency> <!-- Spring依赖 --> <!--1)spring核心依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.1.6.RELEASE</version> </dependency> <!--spring ioc依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.1.6.RELEASE</version> </dependency> <!--2 spring坐标依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.1.6.RELEASE</version> <scope>runtime</scope> </dependency> <!--3 spring web相关依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.1.6.RELEASE</version> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.1.6.RELEASE</version> </dependency> <!--4spring dao层依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.1.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.1.6.RELEASE</version> </dependency> <!--5spring test相关依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.1.6.RELEASE</version> </dependency> <!-- 引入mybatis依赖坐标 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.1</version> <scope>runtime</scope> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.0</version> </dependency> <!-- 引入jstl包 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 引入mysql驱动包--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.32</version> </dependency> <!-- 数据库连接池的包 --> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-dbcp2</artifactId> <version>2.1.1</version> <scope>runtime</scope> </dependency>保存后等待下载完成，入过这个时候jsp文件报错找不到servlet什么包的，可以右击项目properties->java build path，将tomcat添加到libraries中。applicationContext-dao.xml文件

@Service()public class UserServiceImpl implements UserService {@Autowiredprivate UserDao userDao;public User getUserList(HashMap<String, String> map) {// TODO Auto-generated method stubreturn userDao.getUserList(map);}}其他jsp文件我就不贴出来了，随便写一个简单的登录界面就行。
至此一个简单的ssm+maven实现登录的功能就实现了。
