spring--Three Frame integration

Integration Principle

Integration steps:

1. Guide Package

2. Configure the spring container separately

Import constraint (Spring-config.xml)

<?xml version= "1.0" encoding= "UTF-8"? ><beans xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"       xmlns= "Http://www.springframework.org/schema/beans"       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-4.2.xsdhttp://www.springframework.org/schema/context/HTTP WWW.SPRINGFRAMEWORK.ORG/SCHEMA/CONTEXT/SPRING-CONTEXT-4.2.XSDHTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP/HTTP WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP/SPRING-AOP-4.2.XSDHTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/TX/HTTP Www.springframework.org/schema/tx/spring-tx-4.2.xsd ">

Configure spring to launch with Project (Web. xml)

<!--allows the spring container to be created with the start of the project and destroyed with the closure of the project--><listener>    <listener-class> org.springframework.web.context.contextloaderlistener</listener-class></listener><!-- Specify the location to load the spring configuration file--><context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:spring-config.xml</param-value></context-param>

3, separate configuration struts2

Configuring Core Filters

<!--configuring Struts2 core Filters--><filter>    <filter-name>struts2</filter-name>    < filter-class>org.apache.struts2.dispatcher.filter.strutsprepareandexecutefilter</filter-class></ filter><filter-mapping>    <filter-name>struts2</filter-name>    <url-pattern>/* </url-pattern></filter-mapping>

4, STRUTS2 and spring integration

Configuration Constants (Struts.xml)

<!--give the Struts object to spring to create--><constant name= "Struts.objectfactory" value= "Spring" ></constant>

Configuration Spring is responsible for creating the action and assembling

Spring-config.xml

<!--action--><!--Note: The action object must be scoped to a number of cases. This conforms to the STRUTS2 architecture--><bean name= "Useraction" class= " Cn.x5456.web.action.UserAction "scope=" prototype ">    <property name=" UserService "ref=" UserService "> </property></bean>

Struts.xml

<package name= "CRM" namespace= "/" extends= "Struts-default" >    <!--Configure global exceptions---    < global-exception-mappings>        <exception-mapping exception= "java.lang.RuntimeException" result= "error" ></exception-mapping>    </global-exception-mappings>    <action name= "useraction_*" class= " Useraction "method=" {1} > <!--change the value of class to the name of the spring management Object--        <result name= "error" type= "redirect" >/ login.jsp</result>        <result name= "Success" type= "redirect" >/index.htm</result>        < Allowed-methods>login</allowed-methods>     </action></package>

5. Configure Hibernate separately

Import entity Class &orm metadata

Configuration file

<?xml version= "1.0" encoding= "UTF-8"? ><! DOCTYPE hibernate-configuration Public "-//hibernate/hibernate configuration DTD 3.0//en" "http://www.hibernate.org/ Dtd/hibernate-configuration-3.0.dtd ">6. Spring Integration Hibernate
Give the Sessionfactory object to the Spring container management (you can not hibernate.xml the configuration file at this time)
　　<!--Configure Sessionfactory to Container--<bean name= "Sessionfactory" class= " Org.springframework.orm.hibernate5.LocalSessionFactoryBean "> <!--Configure hibernate basic information-<property Name= "Hibernateproperties" > <props> <!--required configuration--<prop key= "h Ibernate.connection.driver_class ">com.mysql.jdbc.Driver</prop> <prop key=" hibernate.connection . url ">jdbc:mysql:///xingedb</prop> <prop key=" Hibernate.connection.username ">root</prop > <prop key= "Hibernate.connection.password" >xxx</prop> <prop key= "Hiberna Te.dialect >org.hibernate.dialect.MySQLDialect</prop> <!--optional configuration-<pro                P key= "Hibernate.show_sql" >true</prop> <prop key= "Hibernate.format_sql" >true</prop> <prop key= "Hibernate.hbm2ddl.auto" >update</pRop> </props> </property> <!--introduce ORM metadata that specifies the package path where ORM metadata is located, and spring automatically reads all the configurations in the package--&gt        ; <property name= "mappingdirectorylocations" value= "Classpath:cn/x5456/domain" ></property> </bean >
7. Spring Integrated C3P0 Connection pool
Prepare Db.properties
#加一个 (any) prefix to prevent collisions with keywords jdbc.jdbcurl=jdbc:mysql:///xingedbjdbc.driverclass=com.mysql.jdbc.driverjdbc.user= Rootjdbc.password=xxx
Configuration file
<!--1. Set Read Db.properties file--><context:property-placeholder location= "Classpath:db.properties" ></ context:property-placeholder><!--2. Set Connection pool--><bean name= "DataSource" class= " Com.mchange.v2.c3p0.ComboPooledDataSource "> <property name=" driverclass "value=" ${jdbc.driverclass} ">  </property> <property name= "Jdbcurl" value= "${jdbc.jdbcurl}" ></property> <property name= "User" Value= "${jdbc.user}" ></property> <property name= "Password" value= "${jdbc.password}" ></property ></bean><!--Configure Sessionfactory to container--><bean name= "sessionfactory" class= " Org.springframework.orm.hibernate5.LocalSessionFactoryBean "> <!--3. Inject the connection pool sessionfactory--> <property Name= "DataSource" ref= "DataSource" ></property> <!--Configure Hibernate basic information--<property name= "Hibernatep Roperties "> <props> <!--required configuration, because of the use of connection pooling (configured in the connection pool), these 4 items are not available – <!--<prop Ke Y= "Hibernate.connection.driver_class ">com.mysql.jdbc.Driver</prop>--> <!--<prop key=" hibernate. Connection.url ">jdbc:mysql:///xingedb</prop>--> <!--<prop key=" Hibernate.connection.username ">root</prop>--> <!--<prop key=" Hibernate.connection.password ">710130520a</prop>-- > <prop key= "hibernate.dialect" >org.hibernate.dialect.MySQLDialect</prop> <!--available Optional configuration-<prop key= "Hibernate.show_sql" >true</prop> <prop key= "hibernate.format_sq    L ">true</prop> <prop key=" Hibernate.hbm2ddl.auto ">update</prop> </props> </property> <!--introduce ORM metadata that specifies the package path where ORM metadata is located, and spring automatically reads all the configurations in the package--<property name= "Mappingdirectoryloca tions "value=" Classpath:cn/x5456/domain "></property></bean>
8, Spring integrated Hibernate environment Operation database
Query method:
public class Userdaoimpl extends Hibernatedaosupport implements Userdao {//via integrated Hibernatedaosupport, Get hibernatetemplate Public user Getuserbyusercode (String user_code) {//Method one: hql query User u = Super.gethib Ernatetemplate (). Execute (new hibernatecallback<user> () {@Override public User doinhibernate (S                Ession session) throws Hibernateexception {String hql = "from User where user_code=?";                Query query = session.createquery (HQL);                Query.setparameter (0, User_code);                User U = (user) query.uniqueresult ();            return u;        }        });        return u;    Method Two: Criteria query Detachedcriteria DC = Detachedcriteria.forclass (User.class);        Offline Object Dc.add (Restrictions.eq ("User_code", User_code));　　list<user> list = (list<user>) super.gethibernatetemplate (). Findbycriteria (DC);         Returns only list if (List!=null&&list.size () >0) {   Return List.get (0);        }else {return null; }    }}
Need to provide Sessionfactory object
<bean name= "Userdao" class= "Cn.x5456.dao.impl.UserDaoImpl" >    <property name= "sessionfactory" ref= " Sessionfactory "></property></bean>
9. Hibernate version of AOP transaction
Core transaction manager (only this and JDBC version < inject connection pool > different)
<!--core transaction manager--><bean Name= "TransactionManager" class= " Org.springframework.orm.hibernate5.HibernateTransactionManager ">    <property name=" sessionfactory "ref=" Sessionfactory "></property></bean>
Method One: Configure notifications and weave in
<!--configuration notification--><tx:advice id= "Txadvice" transaction-manager= "TransactionManager" > <tx:attributes> <tx:method name= "save*" isolation= "Repeatable_read" propagation= "REQUIRED" read-only= "false"/> <tx:meth OD name= "persist*" isolation= "Repeatable_read" propagation= "REQUIRED" read-only= "false"/> <tx:method name= "u pdate* "isolation=" Repeatable_read "propagation=" REQUIRED "read-only=" false "/> <tx:method name=" modify* "ISO lation= "Repeatable_read" propagation= "REQUIRED" read-only= "false"/> <tx:method name= "delete*" isolation= "REP Eatable_read "propagation=" REQUIRED "read-only=" false "/> <tx:method name=" remove* "isolation=" Repeatable_rea D "propagation=" REQUIRED "read-only=" false "/> <tx:method name=" get* "isolation=" repeatable_read "propagation = "REQUIRED" read-only= "true"/> <tx:method name= "find*" isolation= "Repeatable_read" propagation= "REQUIRED" re    Ad-only= "true"/></tx:attributes></tx:advice><!--configuration notifies the target object, configures the Pointcut, and configures the slice--><aop:config> <aop:pointcut expression= "Execution (* cn.x5456.service.impl.*serviceimpl.* (..))" id= "txpc"/> <aop:advisor advice-ref= " Txadvice "pointcut-ref=" txpc "/></aop:config>
Method Two: Configure annotation transactions
<!--open annotation transaction--><tx:annotation-driven transaction-manager= "TransactionManager"/>
10, expand the scope of the session
To avoid no-session problems when using lazy loading. Need to expand the scope of the session
Configure Filter
<!--Extended Session Scope Note: Any filter must be called before the filter of struts (because if the Struts interceptor is not released, it will simply not be able to get to our filter)--><filter>    <filter-name>openSessionInView</filter-name>    <filter-class> org.springframework.orm.hibernate5.support.opensessioninviewfilter</filter-class></filter><!-- Configuring STRUTS2 Core Filters--><filter>    <filter-name>struts2</filter-name>    <filter-class> org.apache.struts2.dispatcher.filter.strutsprepareandexecutefilter</filter-class></filter>< filter-mapping>    <filter-name>openSessionInView</filter-name>    <url-pattern>/*</ Url-pattern></filter-mapping><filter-mapping>    <filter-name>struts2</filter-name >    <url-pattern>/*</url-pattern></filter-mapping>
