SPRING4/SPRING-MVC/HIBERNATE4 Integration III based on Eclipse MAVEN: the application of hibernate4 generic DAO __hibernate

First, the AOP proxy is set to Cglib dynamic Proxy, and in Spring-hibernate.xml, add:

<aop:aspectj-autoproxy  proxy-target-class= "true"/>

It is generally desirable to define DAO base classes as generics, with generic interfaces, to use interface references in Controller/service, and to configure the truly implemented generic DAO classes in XML.

1. Define the DAO implementation class and its interfaces that support generics:

public class Hibernateentitydao<t> extends Hibernategenericdao implements
Ihibernateentitydao<t> ...

2, for example, now to do entity for Tauser DAO implementation class, very simple: to specify the type of entity can be:

public class Hibernateuserdao extends hibernateentitydao<tauser> {	
}

3, the individual tends to DAO in the spring XML configuration without @repository annotations, because later to change the logic of what, directly in the XML will implement the class point to the new class. This is configured inside the Spring-dao.xml:

<bean id= "Hibernateuserdao" class= "Com.freestyle.test.hibernate.dao.HibernateUserDao"/>

4, in the controller inside the test, the following code, the @resource way to inject XML inside the configured Hibernateuserdao to interface Mvdao:

Package Com.freestyle.test.hibernate.controller;
Import java.sql.SQLException;
Import Java.util.HashMap;

Import Java.util.Map;
Import Javax.annotation.Resource;
Import Javax.servlet.http.HttpServletRequest;

Import Javax.servlet.http.HttpServletResponse;
Import Org.springframework.context.annotation.DependsOn;
Import Org.springframework.stereotype.Controller;
Import org.springframework.web.bind.annotation.RequestMapping;
Import Org.springframework.web.bind.annotation.RequestParam;

Import Org.springframework.web.servlet.ModelAndView;
Import Com.freestyle.common.hibernate.dao.interfaces.IHibernateEntityDao;


Import Com.freestyle.test.hibernate.entities.TaUser; @Controller @RequestMapping ("/hibernate") @DependsOn ({"Hibernateuserdao"}) public class Hibernatecontroller Implements org.springframework.web.servlet.mvc.controller{//@Resource (name= "Hibernateuserdao")//private
	Hibernateuserdao Lvdao; @Resource (name= "Hibernateuserdao") @Resource (name= "Hibernateuserdao") protected IhibErnateentitydao<tauser> Mvdao; 
			@RequestMapping ("/test") public Modelandview test (@RequestParam (value = "Name", DefaultValue = "World") String name)
		Throws SQLException {System.out.println ("Hello" + name);
		Map<string, object> lvmap= new hashmap<string, object> ();
		/*tauser lvuser= lvdao.getuser ("DGMISLRH");
		if (lvuser!=null) {System.out.println (Lvuser.getfaname ());
		}*/tauser Lvuser=mvdao.get (name);
			if (lvuser!=null) {System.out.println (Lvuser.getfaname ());
		Lvmap.put ("UserName", Lvuser.getfaname ());
		
	Return to New Modelandview ("/hello", Lvmap); Public Modelandview HandleRequest (httpservletrequest request, httpservletresponse response) throws Exception {Sy
		Stem.out.println (Request.getparametermap (). toString ());
	return null; }

}

Start Tomcat debugging, enter HTTP://LOCALHOST/GPCHAT/HIBERNATE/TEST?NAME=DGMISLRH on the browser, and display the log on the console:
