spring mvc4.1.6 spring4.1.6 hibernate4.3.11 mysql5.5.25开发环境搭建图文教程
一、准备工作
开始之前,先参考上一篇:
思路都是一样的,只不过把struts2替换成了spring mvc
二、不同的地方
工程目录及jar包:
action包改成controller;
删除struts2 jar包,添加spring mvc包(已有的话,不需添加);
web.xml配置:
跟之前不同的地方是把struts2的过滤器替换成了一个servlet,主要目的是路由url,交给spring mvc处理;
<?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" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="webapp_id" version="3.0"> <display-name>ssh</display-name> <context-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:applicationcontext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param> <param-name>contextconfiglocation</param-name> <param-value>classpath:springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
applicationcontext.xml配置:
不同的地方主要是配置自动扫描的时候,要排除@controller组件,这些bean是由spring mvc 去生成的;
其它配置跟前一篇一样;
<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:jdbc="http://www.springframework.org/schema/jdbc" 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/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!-- scans the classpath for annotated components (including @repostory and @service that will be auto-registered as spring beans --> <context:component-scan base-package="ssh" > <!--排除@controller组件,该组件由springmvc配置文件扫描 --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.controller" /> </context:component-scan> <!--配数据源 --> <bean name="datasource" class="com.mchange.v2.c3p0.combopooleddatasource" destroy-method="close"> <property name="driverclass" value="com.mysql.jdbc.driver" /> <property name="jdbcurl" value="jdbc:mysql://localhost:3306/demo" /> <property name="user" value="root" /> <property name="password" value="root" /> <property name="acquireincrement" value="1"></property> <property name="initialpoolsize" value="80"></property> <property name="maxidletime" value="60"></property> <property name="maxpoolsize" value="80"></property> <property name="minpoolsize" value="50"></property> <property name="acquireretrydelay" value="1000"></property> <property name="acquireretryattempts" value="60"></property> <property name="breakafteracquirefailure" value="false"></property> <!-- 如出现too many connections, 注意修改mysql的配置文件my.ini,增大最多连接数配置项,(查看当前连接命令:show processlist) --> </bean> <bean id="sessionfactory" class="org.springframework.orm.hibernate4.localsessionfactorybean"> <property name="datasource" ref="datasource" /> <property name="hibernateproperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.mysqldialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="connection.pool_size">10</prop> <prop key="current_session_context_class">thread</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.ehcacheregionfactory</prop> <prop key="hibernate.cache.use_query_cache">true</prop> <prop key="hibernate.cache.provider_configuration_file_resource_path">ehcache.xml</prop> </props> </property> <property name="mappinglocations"> <list> <value>classpath:ssh/model/user.hbm.xml</value> </list> </property> <!-- <property name="annotatedclasses"> <list> <value>ssh.model.user</value> </list> </property> --> </bean> <!-- 配置事务管理器 --> <bean id="transactionmanager" class="org.springframework.orm.hibernate4.hibernatetransactionmanager"> <property name="sessionfactory" ref="sessionfactory" /> </bean> <!-- 事务的传播特性 --> <tx:advice id="txadvice" transaction-manager="transactionmanager"> <tx:attributes> <tx:method name="add*" propagation="required" read-only="false" rollback-for="java.lang.exception"/> <tx:method name="delete*" propagation="required" read-only="false" rollback-for="java.lang.exception"/> <tx:method name="update*" propagation="required" read-only="false" rollback-for="java.lang.exception"/> <tx:method name="save*" propagation="required" read-only="false" rollback-for="java.lang.exception"/> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="pcmethod" expression="execution(* ssh.service..*.*(..))" /> <aop:advisor pointcut-ref="pcmethod" advice-ref="txadvice" /> </aop:config> <!-- 自定义aop处理 测试 --> <bean id="aoptest" class="ssh.aop.aoptest"></bean> <bean id="myaop" class="ssh.aop.myaop"></bean> <aop:config proxy-target-class="true"> <aop:aspect ref="myaop"> <aop:pointcut id="pcmethodtest" expression="execution(* ssh.aop.aoptest.test*(..))"/> <aop:before pointcut-ref="pcmethodtest" method="before"/> <aop:after pointcut-ref="pcmethodtest" method="after"/> </aop:aspect> </aop:config> </beans>
springmvc-servlet.xml配置:
配置自动扫描ssh.controller包下的@controller,这里要恢复applicationcontext.xml中配置的exclude-filter;
配置视图解析器,有很多解析器,这里以internalresourceviewresolver为例;
<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemalocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd "> <!-- 启动自动扫描该包下所有的bean(例如@controller) --> <context:component-scan base-package="ssh.controller" > <!-- 恢复父容器设置的 exclude-filter,注意包扫描路径ssh.controller--> <context:include-filter type="annotation" expression="org.springframework.stereotype.controller" /> </context:component-scan> <!-- 定义视图解析器 --> <bean class="org.springframework.web.servlet.view.internalresourceviewresolver"> <property name="prefix"> <value>/web-inf/jsp/</value> </property> <property name="suffix"> <value>.jsp</value> </property> </bean> </beans>
编写controller:
由于使用spring mvc替换struts2,也就没有了action包了,删除,并新建controller包,在包下新建usercontroller类;
@requestmapping:映射url;
@responsebody:内容直接作为body返回;
usercontroller.java
package ssh.controller; import java.io.printwriter; import java.util.list; import javax.annotation.resource; import javax.servlet.http.httpservletrequest; import javax.servlet.http.httpservletresponse; import org.apache.log4j.logger; import org.springframework.stereotype.controller; import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.bind.annotation.responsebody; import ssh.aop.aoptest; import ssh.model.user; import ssh.service.userservice; import com.google.gson.gson; @controller @requestmapping("/user") public class usercontroller { logger logger = logger.getlogger(usercontroller.class); @resource private userservice userservice; @resource private aoptest aoptest; @requestmapping(value="/adduser") @responsebody public void adduser(httpservletrequest request, httpservletresponse response){ printwriter out = null; try{ response.setcontenttype("text/html;charset=utf-8"); string account = request.getparameter("account"); string name = request.getparameter("name"); string address = request.getparameter("address"); user user = new user(); user.setaccount(account); user.setaddress(address); user.setname(name); userservice.add(user); out = response.getwriter(); out.write(new gson().tojson("success")); }catch(exception e){ e.printstacktrace(); logger.error(e.getmessage()); if(out != null) out.write(new gson().tojson("fail")); }finally{ out.flush(); out.close(); } } @requestmapping(value="/queryuser") @responsebody public void queryalluser(httpservletrequest request, httpservletresponse response){ printwriter out = null; aoptest.test1(); aoptest.test2(); try { response.setcontenttype("text/html;charset=utf-8"); gson gson = new gson(); list<user> userlist= userservice.queryalluser(); string gsonstr = gson.tojson(userlist); out = response.getwriter(); out.write(gsonstr); } catch (exception e) { e.printstacktrace(); logger.error(e.getmessage()); if(out != null) out.write(new gson().tojson("fail")); }finally{ out.flush(); out.close(); } } }
三、运行程序
运行程序,添加用户、查询用户功能正常;
另外二级缓存也正常工作,第二次查询已经没有操作数据库了;
