首先创建applicationContext.xml文件并把文件头部引用写好
<?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.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 ">
一丶配置数据库账号和密码的jdbc.properties文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/tangcco
jdbc.username=root
jdbc.password=admin
二丶编写applicationContext.xml文件
<!--开启注解扫描器 注在spring某一个版本后可以不写这段代码-->
<context:annotation-config></context:annotation-config>
<!--扫描某一个包下的注解-->
<context:component-scan base-package="cn.bdqn.tangcco">
<!--在这里不扫springmvc Controller的注解-->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--加载properties文件-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!--配置数据源链接池-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<!--配置mybatis的整合-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--指向数据源-->
<property name="dataSource" ref="dataSource"></property>
<!--给实体起别名-->
<property name="typeAliasesPackage" value="cn.bdqn.tangcco.entity"></property>
<!--指定Mapper文件在什么路径-->
<property name="mapperLocations" value="classpath:cn/bdqn/tangcco/mapper/*.xml"></property>
<!--引用page分页接口-->
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties" >
<value>
<!--offsetAsPageNum=true-->
<!--rowBoundsWithCount=true-->
<!--pageSizeZero=truereasonable=false-->
<!--reasonable=true-->
reasonable=true
supporyMethodsArguments=true
<!--params=pageNum=pageHelperStart;pageSize=pageHelperRows;-->
params=count=countSql
antoRuntimeDialect=true
<!--supportMethodsArguments=false-->
</value>
</property>
</bean>
</array>
</property>
</bean>
<!--配置扫描器,将mybatis接口的实现加入到IOC容器中-->
<bean id="scannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--扫描所有Dao接口的-->
<property name="basePackage" value="cn.bdqn.tangcco.*.dao"></property>
<!--引用工厂-->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!--事务管理控制事务源-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!--配置事务控制-->
<!--配置事务规则 txAdvices-->
<tx:advice id="txAdvices" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED"/>
<tx:method name="save*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="find*" read-only="true"/>
<tx:method name="get*" read-only="true"/>
<tx:method name="query*" read-only="true"/>
<tx:method name="*" read-only="true"/>
</tx:attributes>
</tx:advice>
<aop:config>
<!--切入点表达式-->
<!--第一个 * 代表返回值-->
<!--第二个 * 代表所有包-->
<!--第三个 * 代表所有类-->
<!--第四个 * 代表所有方法-->
<!-- 最后 (..) 代表所有的参数-->
<aop:pointcut id="txPointCut" expression="execution(* cn.*.services.impl.*.*(..))"/>
<!--增强事务,配置事务规则-->
<aop:advisor advice-ref="txAdvices" pointcut-ref="txPointCut"/>
</aop:config>
三丶接下来配置srpingmvc.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:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!--扫描指定包下所有的Spring注解生效--> <!-- 禁用掉默认扫描全部--> <context:component-scan base-package="cn.bdqn.tangcco" use-default-filters="false"> <!--只扫描指定注解--> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:include-filter> </context:component-scan> <!--能支持一些SpringMVC更高级的功能,比如JSR303校验,快捷的的ajax请求 等等--> <mvc:annotation-driven></mvc:annotation-driven> <!--将SpringMVC不能处理的请求交给Tomcat--> <mvc:default-servlet-handler/> <!--配置拦截器 可以有多个拦截器，但每个拦截器必须实现HandlerInterceptor接口--> <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/**"></mvc:mapping> <bean class="cn.bdqn.tangcco.command.filter.UserInterceptor"> <!--配置类里的excludedUrls属性把不拦截的url配置进list里--> <property name="excludedUrls"> <list> <value>/login.controller</value> </list> </property> </bean> </mvc:interceptor> </mvc:interceptors> <!--视图解析器--> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!--前缀--> <property name="prefix" value="/WEB-INF/jsp/"></property> <!--后缀--> <property name="suffix" value=".jsp"></property> </bean> </beans>
五丶编写登录拦截器
public class UserInterceptor implements HandlerInterceptor { //存放不需要拦截的url private List<String> excludedUrls; @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { //获取请求的url String url = request.getRequestURI(); //循坏无需拦截的url for (String s:excludedUrls){ //如果当前请求的相等于不拦截url则不拦截 if (s.equals(url)) { return true; } } //获取session里的用户 Tbuser tbuser = (Tbuser) request.getSession().getAttribute("user"); //如果session没有用户则拦截并返回登录页面传递请登录信息 if (tbuser==null) { request.setAttribute("msg","请登录!"); request.getRequestDispatcher("/index.jsp").forward(request,response); return false; } return true; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception { } public List<String> getExcludedUrls() { return excludedUrls; } public void setExcludedUrls(List<String> excludedUrls) { this.excludedUrls = excludedUrls; } }
六丶编写web.xml文件配置
<?xml version="1.0" encoding="UTF-8"?> <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"> <!--加载初始化上下文配置文件--> <context-param> <param-name>contextConfigLocation</param-name> <!--配置文件地址--> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--配置SpringMVC响应编码格式--> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <!--初始化字符编码--> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> <!--转发字符编号启动--> <init-param> <param-name>forceRequestEncoding</param-name> <param-value>true</param-value> </init-param> <!--响应字符编号启动--> <init-param> <param-name>forceResponseEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--配置REST风格的URL，将页面的普通的post请求转为指定的put，或delete--> <filter> <filter-name>hiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>hiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--配置SpringMVC处理servlet的请求--> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!--指定MVC文件地址--> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <!--当初始化时，初始化的顺序--> <load-on-startup>1</load-on-startup> </servlet> <!--所有.controller结尾的URL都交给SpringMVC处理--> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.controller</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
到此全部配置已完成，只需要编写自己所需代码即可
