Actual combat 3--Design Management module, INTEGRATED!!!

1. All DAO and Daoimpl modules are not used, plus @Deprecated

2. Establishment of Daosupport class and Daosupportimpl class

Daosupport.java

Package Cn.itcast.oa.base;import Java.util.list;public interface daosupport<t> {void save (T entity); void Delete ( Long ID); void update (T entity); T getById (Long ID); List<t> getbyids (long[] IDs); List<t> findAll ();}

Daosupportimpl.java

Package Cn.itcast.oa.base;import Java.lang.reflect.parameterizedtype;import Java.util.list;import Javax.annotation.resource;import Org.hibernate.session;import org.hibernate.SessionFactory;
@SuppressWarnings ("Unchecked") public class Daosupportimpl<t> implements daosupport<t> {@Resourceprivate Sessionfactory sessionfactory;private class<t> clazz = Null;public Daosupportimpl () {// Use the reflection technique to get the real type of t parameterizedtype pt = (parameterizedtype) this.getclass (). Getgenericsuperclass ();// Gets the parent class type of the current new object's generic This.clazz = (class<t>) pt.getactualtypearguments () [0]; System.out.println ("clazz===>" +clazz.getname ()); System.out.println ("clazz===>" +clazz.getsimplename ());} Protected Session getsession () {return sessionfactory.getcurrentsession ();} public void Save (T entity) {getsession (). Save (entity); public void update (T entity) {getsession (). Update (entity);} public void Delete (Long id) {Object obj = getById (ID); if (obj! = null) {getsession (). Delete (obj);}} Public T getById (Long ID) {if (id = = NULL) return Null;elsereturn (T) getsession (). Get (Clazz, id);} Public list<t> getbyids (long[] IDs) {return getsession (). CreateQuery (//"from" + clazz.getsimplename () + "WHERE ID In (:IDS)//.setparameterlist ("IDs", IDs). List ();} Public list<t> FindAll () {return getsession (). CreateQuery (//"from" + Clazz.getsimplename ()).//list ();}}

3. Extract the baseaction so that each action can focus on writing its own methods    

package Cn.itcast.oa.base;import Java.lang.reflect.parameterizedtype;import Javax.annotation.resource;import Cn.itcast.oa.service.departmentservice;import Cn.itcast.oa.service.RoleService; Import Cn.itcast.oa.service.userservice;import Com.opensymphony.xwork2.actionsupport;import Com.opensymphony.xwork2.modeldriven;public abstract class Baseaction<t> extends Actionsupport implements modeldriven<t>{protected T model;p ublic baseaction () {try {//by reflecting the real type of the live model Parameterizedtype pt = ( Parameterizedtype) This.getclass (). Getgenericsuperclass (); Class<t> clazz = (class<t>) pt.getactualtypearguments () [0];//creates an instance of model by Reflection model = Clazz.newinstance ();} catch (Exception e) {throw new RuntimeException ();}} Public T Getmodel () {return model;} The Declaration of the service instance ****************** @Resourceprotected roleservice roleservice; @Resourceprotected Departmentservice departmentservice; @Resourceprotected userservice userservice;} 

Integration Complete!!!

Steps to add a new module:

I. Preparing to create an action

1. Write a new action, Useraction.java,

1) extends Baseaction

2) @Controller @Scope ("prototype")

2. Define the method of action, write out the method name, function, return value

/** */public String list () throws Exception {return "list";} /** Delete */public String Delete () throws Exception {return "toList";} /** Add page */public String Addui () throws Exception {return "Saveui";} /** Add */public String Add () throws Exception {return "toList";} /** Modify Page */public String Editui () throws Exception {return "Saveui";} /** Modify */public String edit () throws Exception {return "toList";}        /** Initialize password 1234 **/public String Initpassword () throws Exception {return "toList";}    

3. Create the JSP page used (list.jsp, saveui.jsp)

4. struts.xml Configuration

<!--user management--><action name= "user_*" class= "useraction" method= "{1}" ><result name= "list" >/web-inf/ Jsp/useraction/list.jsp</result><result name= "Saveui" >/web-inf/jsp/useraction/saveui.jsp</result ><result name= "toList" type= "Redirectaction" >user_list?parentid=${parentid}</result></action >

　　

Two. Prepare the service

1. Create interface Userservice.java, extends daosupport<user>

Package Cn.itcast.oa.service;import Cn.itcast.oa.base.daosupport;import Cn.itcast.oa.domain.user;public interface UserService  extends daosupport<user>{}

2. Create the implementation class Userserviceimpl.java, extends Daosupportimpl<user> implements UserService

3. Configuration: Write annotations @Service on Userserviceimpl @Transactional

Package Cn.itcast.oa.service.impl;import Org.springframework.stereotype.service;import Org.springframework.transaction.annotation.transactional;import Cn.itcast.oa.base.daosupportimpl;import Cn.itcast.oa.domain.user;import Cn.itcast.oa.service.UserService; @Service @transactionalpublic class Userserviceimpl extends daosupportimpl<user> implements userservice{}

4. Statement of service written in Baseaction

package Cn.itcast.oa.base;import Java.lang.reflect.parameterizedtype;import Javax.annotation.resource;import Cn.itcast.oa.service.departmentservice;import Cn.itcast.oa.service.RoleService; Import Cn.itcast.oa.service.userservice;import Com.opensymphony.xwork2.actionsupport;import Com.opensymphony.xwork2.modeldriven;public abstract class Baseaction<t> extends Actionsupport implements modeldriven<t>{protected T model;p ublic baseaction () {try {//by reflecting the real type of the live model Parameterizedtype pt = ( Parameterizedtype) This.getclass (). Getgenericsuperclass (); Class<t> clazz = (class<t>) pt.getactualtypearguments () [0];//creates an instance of model by Reflection model = Clazz.newinstance ();} catch (Exception e) {throw new RuntimeException ();}} Public T Getmodel () {return model;} The Declaration of the service instance ****************** @Resourceprotected roleservice roleservice; @Resourceprotected Departmentservice departmentservice; @Resourceprotected userservice userservice;}
