使用maven整合Spring+SpringMVC+Mybatis框架详细步骤(图文)
(项目结构图参照文章末尾)
1、创建maven工程,在pom.xml文件中导入需要的jar包依赖:
<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

<version>3.2</version> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build> </project>
2、整合SpringMVC:
(1)在web.xml文件中配置前端控制器:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="serviceMarket" version="2.5"> <display-name>ssm-test</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 加载spring相关配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 解决post乱码 --> <filter> <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- springmvc的前端控制器 --> <servlet> <servlet-name>ssm-test</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 加载springmvc的配置文件(处理器映射器、处理器适配器等等) --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>ssm-test</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
(2)编写springmvc.xml文件:
在文件中配置与springmvc框架相关的配置,比如:springmvc.xml约束、处理器映射器、处理器适配器、视图解析器、Handler等配置。
<?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"> <!-- 使用注解驱动:自动配置处理器映射器与处理器适配器 --> <mvc:annotation-driven /> <!-- 注解方式:配置Handler,自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器 --> <!-- 批量加载:组件扫描方式: --> <context:component-scan base-package="com.zwp.controller" /> <!-- 视图解析器:解析jsp页面,默认使用jstl标签,classpath下得有jstl的包 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 配置前后缀 --> <property name="prefix" value="/WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean> <!-- 静态资源处理,不拦截静态资源,如css、js、imgs --> <mvc:resources location="/static/css/" mapping="/static/css/**"/> <mvc:resources location="/static/js/" mapping="/static/js/**"/> <mvc:resources location="/static/img/" mapping="/static/img/**"/> <!-- 文件上传相关配置 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="UTF-8"></property> <property name="maxUploadSize" value="10240000"></property> </bean> </beans>
(3)编写Handler:
//User类的Handler //需要在类上面加@Controller注解,这样才能被自动扫描到 @Controller @RequestMapping("/user") public class UserController { private static Logger log=LoggerFactory.getLogger(UserController.class); @RequestMapping(value="/login",method=RequestMethod.GET) public String login(HttpServletRequest request,Model model){ String username = request.getParameter("username"); String password = request.getParameter("password"); System.out.println("username:"+username+";password:"+password); User user=null; if (username.equals("zwp") && password.equals("123456")) { user = new User(); user.setAge(11); user.setId(1); user.setPassword("123456"); user.setUsername("zwp"); log.debug(user.toString()); } model.addAttribute("user", user); return "index"; } }
//User实体类 public class User { private Integer id; private String username; private String password; private Integer age; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } @Override public String toString() { return "User [id=" + id + ", username=" + username + ", password=" + password + ", age=" + age + "]"; } }
(4)配置日志文件:
在项目根目录下面创建log4j.properties日志文件,下面是日志文件的基本配置,可以满足大多数项目的需求。
log4j.rootLogger=INFO,Console,File #定义日志输出目的地为控制台 log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.Target=System.out #可以灵活地指定日志输出格式,下面一行是指定具体的格式 log4j.appender.Console.layout = org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n #文件大小到达指定尺寸的时候产生一个新的文件 log4j.appender.File = org.apache.log4j.RollingFileAppender #指定输出目录 log4j.appender.File.File = logs/ssm.log #定义文件最大大小 log4j.appender.File.MaxFileSize = 10MB # 输出所以日志,如果换成DEBUG表示输出DEBUG以上级别日志 log4j.appender.File.Threshold = ALL log4j.appender.File.layout = org.apache.log4j.PatternLayout log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
(5)启动项目,进行测试:
访问地址:http://localhost:8080/ssm/user/login?username=zwp&password=123456,如果出现下面页面则代表映射成功。
至此,SpringMVC的配置就已经成功。
3、Spring和Mybatis框架的整合:
整合思路:由Spring通过单例方式管理SqlSessionFactory;spring和mybatis整合生成代理对象,使用SqlSessionFactory创建SqlSession,持久层的mapper都需要有spring进行管理。
(1)配置dao层,即配置sqlSessionFactory:(我的配置在applicationContext-dao.xml文件中)
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 1.加载配置文件 --> <!-- 第一种加载多个.properties文件的方法 --> <context:property-placeholder location="classpath:resource/*.properties"/> <!-- 2.配置数据库连接池 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="driverClassName" value="${jdbc.driver}" /> <property name="maxActive" value="10" /> <property name="minIdle" value="5" /> </bean> <!-- 3.让spring创建并管理sqlsessionfactory,使用mybatis和spring整合包中的 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 配置数据源,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/SqlMapConfig.xml" /> </bean> <!-- 4.mapper批量扫描:从mapper包中扫描出mapper,自动创建代理对象并且在spring容器中注册 需要遵循规范:mapper接口类名和mapper.xml映射文件名称一致,且在同一目录下, 自动扫描出来的mapper的bean的id为类名(首字母小写)--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.zwp.mapper" /> </bean> </beans>
创建并编写SqlMapConfig.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> <plugins> <!-- com.github.pagehelper为PageHelper类所在包名 --> <plugin interceptor="com.github.pagehelper.PageHelper"> <!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库 --> <property name="dialect" value="mysql" /> </plugin> </plugins> </configuration>
(2)配置service层:(我的配置在applicationContext-service.xml文件中)
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 自动扫描service层的接口与实现类 --> <context:component-scan base-package="com.zwp.service" /> </beans>
(3)配置事务:(我的配置在applicationContext-trans.xml文件中)
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" 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-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 数据源 --> <property name="dataSource" ref="dataSource" /> </bean> <!-- 通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 传播行为 --> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="create*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> </tx:attributes> </tx:advice> <!-- 切面 --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.zwp.service.*.*(..))" /> </aop:config> </beans>
至此,Spring和Mybatis框架的整合就完成了。
4、测试:
(1)创建测试用表:
(2)利用MyBatis-Generator自动创建实体类、Mybatis映射文件以及Dao接口。
(3)建立Service和实现类:
//UserService接口类: @Service public interface UserService { public User getUserById(int userId); }
//UserService的实现类 @Service public class UserServiceImpl implements UserService { //注入UserMapper接口 @Autowired private UserMapper userMapper; @Override public User getUserById(int userId) { User user = userMapper.selectByPrimaryKey(userId); return user; } }
(3)建立UserController类:
//User类的Handler //需要在类上面加@Controller注解,这样才能被自动扫描到 @Controller @RequestMapping("/user") public class UserController { @Autowired private UserService userService; private static Logger log=LoggerFactory.getLogger(UserController.class); @RequestMapping(value="/getUserById/{userId}",method=RequestMethod.GET) public @ResponseBody User getUserById(@PathVariable Integer userId){ return userService.getUserById(userId); } @RequestMapping(value="/login",method=RequestMethod.GET) public String login(HttpServletRequest request,Model model){ String username = request.getParameter("username"); String password = request.getParameter("password"); System.out.println("username:"+username+";password:"+password); User user=null; if (username.equals("zwp") && password.equals("123456")) { user = new User(); user.setAge(11); user.setId(1); user.setPassword("123456"); user.setUsername("zwp"); log.debug(user.toString()); } model.addAttribute("user", user); return "index"; } }
(4)部署项目,输入地址:http://localhost:8080/ssm/user/getUserById/2,出现下面响应结果,则表示整合成功了。
至此,Maven+Spring+SpringMVC+Mybatis的整合就完成了。
