第一步：导入相关jar包 springMVC+hibernate
第二步:web-inf下的web.xml配置文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <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="WebApp_ID" version="2.5"> 3 <display-name>json_test</display-name> 4 <welcome-file-list> 5 <welcome-file>login.jsp</welcome-file> 6 </welcome-file-list> 7 8 <!-- 一个web.xml中可以配置多个DispatcherServlet,通过 servlet-mapping的不同设置，让每个DispatcherServlet处理不同的请求--> 9 10 <!-- 业务层和持久层的bean的spring配置文件。applicationContext.xml.多个配置文件使用，号隔开--> 11 <context-param> 12 <param-name>contextConfigLocation</param-name> 13 <param-value>classpath*:config/spring/spring-*.xml</param-value> 14 </context-param> 15 16 <!-- 配置Spring监听 。通过contextConfigLocation配置的xml文件启动业务层（service和dao)的bean的容器。【service层和dao层的容器】--> 17 <listener> 18 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 19 </listener> 20 21 <!-- 配置SpringMVC的DispatcherServlet ，它是springmvc的灵魂和心脏，它协调各组件完成一次完整的请求响应--> 22 <!-- （默认自动加载web-inf下的<servltname>-servlet.xml的spring配置文件）启动web层的spring容器【控制器,请求分发器】 --> 23 <!-- 如果配置init-param则是打破默认自动加载，而是按param-value中的路径，加载web层容器 --> 24 <!-- web层的spring容器是业务层的spring容器的子容器：即web层容器中的bean【controller】可以调用业务层bean【service和dao】而业务层bean调用不到web层的bean --> 25 <servlet> 26 <servlet-name>springMVC</servlet-name> 27 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 28 <init-param> 29 <!-- 装配webApplicationContext容器。其实ApplicationContext容器的子类--> 30 <param-name>contextConfigLocation</param-name> 31 <param-value>classpath*:config/spring/spring-mvc.xml</param-value> 32 </init-param> 33 <load-on-startup>1</load-on-startup> 34 </servlet> 35 <servlet-mapping> 36 <servlet-name>springMVC</servlet-name> 37 <url-pattern>/</url-pattern> 38 </servlet-mapping> 39 40 <!-- 配置字符集 --> 41 <filter> 42 <filter-name>encodingFilter</filter-name> 43 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 44 <init-param> 45 <param-name>encoding</param-name> 46 <param-value>UTF-8</param-value> 47 </init-param> 48 <init-param> 49 <param-name>forceEncoding</param-name> 50 <param-value>true</param-value> 51 </init-param> 52 </filter> 53 <filter-mapping> 54 <filter-name>encodingFilter</filter-name> 55 <url-pattern>/*</url-pattern> 56 </filter-mapping> 57 58 <!-- 配置Session，扩大session的生命周期 --> 59 <filter> 60 <filter-name>openSession</filter-name> 61 <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> 62 </filter> 63 <filter-mapping> 64 <filter-name>openSession</filter-name> 65 <url-pattern>/*</url-pattern> 66 </filter-mapping> 67 </web-app>
spring-mvc.xml配置文件。装配控制器的容器
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans.xsd 8 http://www.springframework.org/schema/context 9 http://www.springframework.org/schema/context/spring-context-3.2.xsd 10 http://www.springframework.org/schema/mvc 11 http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> 12 13 <!--此xml是springMvc是启动控制器和视图解析工具的 --> 14 15 <!-- 注解扫描包 pojo处定义@Controller,此配置扫描相应的类包，将有注解的pojo变成一个可以分发http请求的控制器--> 16 <!-- @Controller将pojo变成可以分发http请求的控制器。 --> 17 <!-- @RequestMapping确定不同请求，调用不同控制器中的某个控制器，然后调用某个控制器中的某个方法 --> 18 <!-- 类头定义@RequestMapping是提供初步的请求映射信息（相对于项目部署），方法头定义@RequestMapping（相对于类头部署）是确定请求所要调用的方法。请求规则包含：url,请求参数，请求方法，请求头 --> 19 <context:component-scan base-package="com.tgb.web" /> 20 21 <!-- <mvc:annotation-driven /> 是一种简写形式，完全可以手动配置替代这种简写形式，简写形式可以让初学都快速应用默认配置方案。<mvc:annotation-driven /> 22 会自动注册DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter 两个bean,是spring MVC为@Controllers分发请求所必须的。 23 并提供了：数据绑定支持，@NumberFormatannotation支持，@DateTimeFormat支持，@Valid支持，读写XML的支持（JAXB），读写JSON的支持（Jackson）。 24 后面，我们处理响应ajax请求时，就使用到了对json的支持。后面，对action写JUnit单元测试时，要从spring IOC容器中取DefaultAnnotationHandlerMapping 25 与AnnotationMethodHandlerAdapter 两个bean，来完成测试，取的时候要知道是<mvc:annotation-driven />这一句注册的这两个bean。--> 26 <mvc:annotation-driven /> 27 28 29 <!-- 静态资源(js/image)的访问 --> 30 <mvc:resources location="/js/" mapping="/js/**"/> 31 32 33 <!-- 定义视图解析器 --> 34 <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 35 <property name="prefix" value="/"></property> 36 <property name="suffix" value=".jsp"></property> 37 </bean> 38 </beans>
spring-common.xml装配ioc容器。连接数据库信息。配置切面，给业务类加事务
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans.xsd"> 8 9 <!-- 配置数据源 --> 10 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" > 11 <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> 12 <property name="url" value="jdbc:mysql://localhost:3306/test"></property> 13 <property name="username" value="root"></property> 14 <property name="password" value="1234"></property> 15 </bean> 16 17 <!-- 配置SessionFactory --> 18 <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 19 <property name="dataSource" ref="dataSource" /> 20 <property name="hibernateProperties"> 21 <props> 22 <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> 23 <prop key="hibernate.hbm2ddl.auto">update</prop> 24 <prop key="hibernate.show_sql">true</prop> 25 <prop key="hibernate.format_sql">true</prop> 26 </props> 27 </property> 28 29 <!-- 【3】mapping数据模型和数据库的桥梁，只需要配置到路径，无需一个个配置 .hibernate的映射文件 类名.hbm.xml--> 30 <property name="mappingDirectoryLocations"> 31 <list> 32 <value>classpath:/com/tgb/entity</value> 33 </list> 34 </property> 35 36 <!-- 注解方式扫描实体类 37 <property name="annotatedClasses"> 38 <list> 39 <value>com.tgb.entity.User</value> 40 </list> 41 </property> 42 --> 43 </bean> 44 45 <!-- 配置springMVC上传文件和下载文件 --> 46 <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 47 <property name="defaultEncoding" value="utf-8"></property><!-- 编码格式，与jsp格式一致 --> 48 <property name="maxUploadSize" value="52428880"></property><!-- 文件上传的最大限制 5mb --> 49 <property name="uploadTempDir" value="upload/temp"></property><!-- 上传文件的临时路径。文件上传后，会自动消失 --> 50 <property name="maxInMemorySize" value="4096"/> 51 </bean> 52 53 54 55 56 <!-- 配置一个事务管理器 --> 57 <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 58 <property name="sessionFactory" ref="sessionFactory"/> 59 </bean> 60 61 <!-- 配置事务，使用代理的方式 --> 62 <bean id="transactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true"> 63 <property name="transactionManager" ref="transactionManager"></property> 64 <property name="transactionAttributes"> 65 <props> 66 <prop key="add*">PROPAGATION_REQUIRED,-Exception</prop> 67 <prop key="update*">PROPAGATION_REQUIRED,-Exception</prop> 68 <prop key="query*">PROPAGATION_REQUIRED,-Exception</prop> 69 <prop key="get*">PROPAGATION_REQUIRED,-Exception</prop> 70 <prop key="count*">PROPAGATION_REQUIRED,-Exception</prop> 71 <prop key="modify*">PROPAGATION_REQUIRED,-myException</prop> 72 <prop key="del*">PROPAGATION_REQUIRED</prop> 73 <prop key="*">PROPAGATION_REQUIRED</prop> 74 </props> 75 </property> 76 </bean> 77 </beans>
spring-beans.xml给业务类加上事务。也可用ssh配置事务的方法
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans.xsd"> 8 <!-- 此处为代理 ,为业务类设置事务--> 9 <bean name="userManager" parent="transactionProxy"> 10 <property name="target" ref="userManagerBase"></property> 11 </bean> 12 13 <bean name="studentService" parent="transactionProxy"> 14 <property name="target" ref="studentServiceBase"></property> 15 </bean> 16 <bean name="classRoomService" parent="transactionProxy"> 17 <property name="target" ref="classRoomServiceBase"></property> 18 </bean> 19 </beans>
spring-service.xml配置项目中业务类的对象
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans.xsd"> 8 9 <bean id="userManagerBase" class="com.tgb.service.serviceImpl.UserManagerImpl" scope="prototype" autowire="byType"></bean> 10 <bean id="studentServiceBase" class="com.tgb.service.serviceImpl.StudentServiceImpl" scope="prototype" autowire="byType"></bean> 11 <bean id="classRoomServiceBase" class="com.tgb.service.serviceImpl.ClassRoomServiceImpl" scope="prototype" autowire="byType"></bean> 12 </beans>
第七步：spring-dao.xml配置项目中dao层的对象
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans.xsd"> 8 9 10 11 <bean id="userDao" class="com.tgb.dao.daoImpl.UserDaoImpl" scope="prototype"> 12 <property name="sessionFactory" ref="sessionFactory"></property> 13 </bean> 14 <bean id="studentDao" class="com.tgb.dao.daoImpl.StudentDaoImpl" scope="prototype"> 15 <property name="sessionFactory" ref="sessionFactory"></property> 16 </bean> 17 <bean id="classRoomDao" class="com.tgb.dao.daoImpl.ClassRoomDaoImpl" scope="prototype"> 18 <property name="sessionFactory" ref="sessionFactory"></property> 19 </bean> 20 </beans>
