Simple SSH2 Environment Construction

I used to build SSH before, but I only used it when I learned it myself. In the company, I am doing some system maintenance, repair and makeup, and I have no chance to create a new system, after a while, I tried to build another SSH environment and found that I had forgotten it. I couldn't help it. I wrote this article here after I made a preliminary setup. I don't have to pay a lot for it in the future.

Procedure:

<1> create a web project and add the following JAR packages to the project path.

<2> modify the Web. xml file to support struts2. The content is as follows:

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <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"> <br/> <display-Name> SSH </display-Name> <br/> <welcome- file-List> <br/> <welcome-File> index.html </welcome-File> <br/> <welcome-File> index.htm </welcome-File> <br/> <welcome-File> index.

<3> it turns out to be an SSH2 framework. Of course, you need to add the configuration files required for the three frameworks.

1. struts2, because it is only a basic configuration, some features may not be configured, and the content of my configuration file is also small, roughly as follows

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <! Doctype struts Public <br/> "-// Apache Software Foundation/DTD struts configuration 2.1.7/EN" <br/> "http://struts.apache.org/dtds/struts-2.1.7.dtd"> <br/> <struts> <br/> <constant name = "struts. objectfactory "value =" Spring "/> </P> <p> <include file =" XML/struts/module1.xml "> </include> <br/> </struts> <br/> 

The idea is to put some common configurations in this file. For the configuration of a specific module, write the configuration file and load it with <include>. The following content is module1.xml:

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <! Doctype struts Public <br/> "-// Apache Software Foundation/DTD struts configuration 2.1.7/EN" <br/> "http://struts.apache.org/dtds/struts-2.1.7.dtd"> <br/> <struts> <br/> <package name = "product" namespace = "/product" extends = "struts-Default"> <br/> <action name = "product _ *" class =" productaction "method =" {1} "> <! -- The class used here should be the bean ID attribute in spring configuration --> <br/> <result name = "result">/WEB-INF/JSP/result. JSP </result> <br/> </Action> <br/> </package> <br/> </struts> <br/> 

2. Configure spring as follows:

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <beans xmlns = "http://www.springframework.org/schema/beans" <br/> xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" <br/> xmlns: context = "http://www.springframework.org/schema/context" <br/> xsi: schemalocation = "<br/> http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd <br/> http://www.springframework.org/schema/context http://www.sprin Gframework.org/schema/context/spring-context-3.0.xsd "> <br/> <context: component-scan base-package =" module1 "/> <! -- Use the annotation scan function to reduce the number of spring configuration files --> </P> <p> <bean id = "datasource" class = "org. springframework. JDBC. datasource. drivermanagerdatasource "> <br/> <property name =" driverclassname "value =" com. mySQL. JDBC. driver "/> <br/> <property name =" url "value =" JDBC: mysql: // localhost/test "/> <br/> <property name =" username "value =" root "/> <br/> <property name =" password "value =" 123456 "/> <br/> </bean> <br/> <! -- <Bean> <br/> <Jee: JNDI-lookup id = "datasource" JNDI-name = "Java: COMP/ENV/jdbc/MySQL "/> <br/> </bean> --> <! -- Some Basic Public configurations are configured in this file --> <br/> <import resource = "applicationContext-hibernate.xml"/> <! -- Separate hibernate integration configuration --> <br/> <import resource = "module1/applicationContext-module1.xml"/> <! -- Configuration of a specific module --> </P> <p> </beans> <br/> 

Spring-hibernate support

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <beans xmlns = "http://www.springframework.org/schema/beans" <br/> xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" <br/> xmlns: context = "http://www.springframework.org/schema/context" <br/> xsi: schemalocation = "<br/> http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd <br/> http://www.springframework.org/schema/context http://www.sprin Gframework.org/schema/context/spring-context-3.0.xsd "> <br/> <bean id =" sessionfactory "class =" org. springframework. orm. hibernate3.localsessionfactorybean "> <br/> <property name =" datasource "ref =" datasource "/> <! -- Use external datasource injection --> <br/> <property name = "mappingresources"> <br/> <list> <br/> <value> module1/Vo/product. HBM. XML </value> <! -- Configuration file of an entity --> <br/> </List> <br/> </property> <br/> <property name = "hibernateproperties"> <br/> <props> <br/> <prop key = "hibernate. dialect "> Org. hibernate. dialect. mysqldialect </prop> <br/> <prop key = "hibernate. show_ SQL "> true </prop> <br/> <prop key =" hibernate. format_ SQL "> true </prop> <br/> </props> <br/> </property> <br/> </bean> </P> <p> <! -- <Br/> <bean id = "hibernatetemplate" class = "org. springframework. orm. hibernate3.hibernatetemplate "> <br/> <property name =" sessionfactory "ref =" sessionfactory "/> <br/> </bean> <br/> --> <br/> <! -- Configure the Transaction Manager. The specific transaction management is not configured here, if you are interested, you can access the relevant information online --> <br/> <bean id = "transactionmanager" class = "org. springframework. orm. hibernate3.hibernatetransactionmanager "> <br/> <property name =" sessionfactory "ref =" sessionfactory "/> <br/> </bean> </P> <p> </beans> <br/> 

Spring-module1 Configuration

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <beans xmlns = "http://www.springframework.org/schema/beans" <br/> xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" <br/> xmlns: context = "http://www.springframework.org/schema/context" <br/> xsi: schemalocation = "<br/> http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd <br/> http://www.springframework.org/schema/context http://www.sprin Gframework.org/schema/context/spring-context-3.0.xsd "> <br/> <! -- The configuration of productaction is not seen in this configuration file because I used @ controller annotation in the class. If you are interested, you can also implement it in the annotation method, here is just an example --> <br/> <bean id = "productdao" class = "module1.dao. productdaoimpl "> <br/> <property name =" sessionfactory "ref =" sessionfactory "/> <br/> </bean> </P> <p> <bean id = "productserver" class = "module1.server. productserverimpl "> <br/> <property name =" productdao "ref =" productdao "/> <br/> </bean> </P> <p> </beans> <br/> 

Productaction content:

Package module1.action; <br/> Import javax. annotation. resource; <br/> Import module1.server. productserver; <br/> Import module1.vo. product; <br/> Import Org. apache. commons. logging. log; <br/> Import Org. apache. commons. logging. logfactory; <br/> Import Org. apache. log4j. logger; <br/> Import Org. springframework. stereotype. controller; <br/> Import COM. opensymphony. xwork2.actioncontext; <br/> import core. baseaction; <br/> @ controller // The Controller annotation is used, register it in the spring window <br/> public class productaction extends baseaction {<br/> // use the spring-implemented resource annotation for object injection, getter and setter are not even required. <br/> @ resource private productserver; <br/> private int ID; </P> <p> Public int GETID () {<br/> return ID; <br/>}< br/> Public void setid (int id) {<br/> This. id = ID; <br/>}< br/> Public String get () {<br/> log.info ("before calling server ----"); <br/> actioncontext. getcontext (). put ("result", productserver. getproductbyid (ID); <br/> log.info ("after calling server ----"); <br/> return "result "; <br/>}< br/> 

3. hibernate configuration: HBM. xml configuration files of specific object are as follows:

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <! Doctype hibernate-mapping Public <br/> "-// hibernate/hibernate DTD ing DTD 3.0/EN" <br/> "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <br/> <pibernate-mapping package = "module1.vo"> <br/> <class name = "product" table = "product"> <br/> <ID name = "ID"> <br/> <generator class = "increment"/> <br/> </ID> <br/> <property name = "name" type = "string"/> <br/> <property name = "cost" type = "Java. math. bigdecimal "/> <br/> </class> <br/> </pibernate-mapping> 

 

So far, the SSH2 configuration has been completed, and a slight adjustment should be able to run the project normally. Of course, many details have not been written, please refer to the official staff for troubleshooting.
