6.spring+struts+hibernat Annotation Method Integration

SSH Annotation Method implementation

1. Create the Db.properties file, mainly the connection data of the database

Jdbc.driverclassname=com.mysql.jdbc.driver
Jdbc.url=jdbc\:mysql\://localhost\:3306/test
Jdbc.username=root
jdbc.password=076634

2. Create a struts configuration file that primarily defines the general configuration of struts

<?xml version= "1.0" encoding= "UTF-8"?>
<! DOCTYPE Struts Public
"-//apache software foundation//dtd Struts Configuration 2.3//en"
"Http://struts.apache.org/dtds/struts-2.3.dtd" >

<!--the general configuration of struts-
<struts>

<constant name= "Struts.devmode" value= "true"/>
<constant name= "Struts.enable.DynamicMethodInvocation" value= "true"/>
<constant name= "struts.objectfactory" value= "Spring"/>

</struts>

3. Defined configuration file

<?xml version= "1.0" encoding= "UTF-8"?>
<beans xmlns= "Http://www.springframework.org/schema/beans"
Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"

<!--auto-Scan Package--
<context:component-scan base-package= "Cn.yunhe"/>

<!--allow things to be annotated-

</property>
</bean>

<!--payees configuration file to build a connection pool--

<property name= "username" value= "${jdbc.username}"/>

</bean>

<property name= "DataSource" ref= "DataSource"/>
<!--scan entity class--

</bean>

<!--initialize Things--

<bean id= "TransactionManager" class= "Org.springframework.orm.hibernate3.HibernateTransactionManager" >
<property name= "Sessionfactory" ref= "Sessionfactory"/>
</bean>
</beans>

5.web.xml Layer

<! DOCTYPE Web-app Public
"-//sun Microsystems, INC.//DTD Web application 2.3//en"
"Http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
<display-name>archetype Created Web application</display-name>

<!--spring Listener to create a spring container when the system is started--
<listener>

</listener>

</web-app>

6. Operation of the in-package class

1: Annotation of entity classes
@Entity
@Table (name = "User")
public class User {....

Primary key:
@Id
@GeneratedValue
@Column (name = "id")
public int getId () {
return ID;
}
Other:
@Column (name = "PWD")

2:dao Layer:

@Repository ("Userdao")
public class Userdaoimpl extends Hibernatedaosupport implements Userdao {

3:biz Layer:

@Service ("Userbiz")
public class Userbizimpl implements Userbiz {
Introducing DAO
@Resource (name = "Userdao")
Private Userdao Userdao;

4:struts Controller

Create a controller for struts

@Controller ("User")
@Scope (value = "Prototype")
@ParentPackage (value = "Struts-default")
public class Usercontroller extends Actionsupport {

Create Biz
@Resource (name = "Userbiz")
Private Userbiz userbiz;

@Action (value = "user", results = {
@Result (name = "Success", location = "/list.jsp")
})
Public String Execute () throws Exception {

list<user> list = Userbiz.searchall ();
Create a stored Actioncontext
Map request = (map) actioncontext.getcontext (). Get ("request");
Request.put ("list", list);
return SUCCESS;
}

Public userbiz getuserbiz () {
return userbiz;
}

public void Setuserbiz (Userbiz userbiz) {
This.userbiz = userbiz;
}
}
