SSH全注解-annotation详细配置

如果有点SSH框架的经验,这个很好理解.配置不难.

配置annotation目的:省去庞大的.XML配置简化配置.其实这个annotation最近才流行的.我配置了几天,愁坏了...

这里写这篇博客就是方便下大家,给大家启示:



首先annotation是spring2.5的新功能.所以项目用Myeclipse里添加spring支持选择spring2.5.添加Hibernate的时候也要添加annotation需要的jar包,按步骤走就可以.需要特殊加的jar包有:struts2-convention-plugin-2.1.6.jar,hibernate-commons-annotations.jar.



web.xml的配置:

<!--Spring的装载器  -->
	<listener> 
      <listener-class> 
         org.springframework.web.context.ContextLoaderListener          
      </listener-class> 
    </listener>
    <!--spring的应用上下文  -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>
 
  <!-- struts2文件拦截器 -->	
    	
	<filter>  
      <filter-name>struts2</filter-name>  
      <filter-class>xx.servlet.web.MyStrutsFilterDispatcher</filter-class>  
	 <init-param>
  	 	<param-name>actionPackages</param-name>
   		<param-value>xx.bean,xx.dao,xx.quanxin.action</param-value>
       </init-param>
	</filter>  
	<filter-mapping>
	  <filter-name>struts2</filter-name>
	  <url-pattern>/*</url-pattern>
	</filter-mapping>

struts.xml基本没用了,所以就省掉了...先鼓掌.

applicationContext.xml就有点改变了,看源码:

		</property>
	</bean>
	<bean id="transactionManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
	
</beans>

注:基本和原来的一样,红色字体是主要变化的...还有头文件也增加了点..到时候复杂就可以了.





再下面就看源码了...简单的东西马上就来了:



DAO层的接口类,也就是Interface没有变化,省掉了.

DAO层的impl文件有变化,看源码:

@Repository("dao")
public class PublicDaoImpl extends HibernateDaoSupport implements PublicDao {
	 
	@Resource(name = "sessionFactory")
    public void setSuperSessionFactory(SessionFactory sessionFactory) {
        super.setSessionFactory(sessionFactory);
    }
	
     public void delete(Object obj) {
	this.getHibernateTemplate().delete(obj);

     }

Service层接口么变化,看impl的源码:

@Service("base")
@Transactional
public class BaseServiceImple implements BaseService {
	@Resource(name="dao")
	private PublicDao publicDao;
	
	
	public PublicDao getPublicDao() {
		return publicDao;
	}

最后看Action里面的配置.最重要的了,看源码:

import javax.annotation.Resource;
import javax.servlet.http.HttpSession;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.ServletActionContext;
import org.springframework.stereotype.Controller;

import xx.bean.UserInfo;
import xx.service.*;
import com.opensymphony.xwork2.ActionSupport;

@Controller
@Namespace("")
@ParentPackage("default-package")
public class UserinfoAction extends ActionSupport {
            @Resource(name="base")
	private BaseService baseService;
 @Action(value="/new",results={@Result(name="success",location="/index.jsp")})
	
	public String newUser() {
		UserInfo xx=new UserInfo();
		xx.setUserid("111");
		xx.setPassword("111");
		xx.setSfz("12121");
		this.baseService.save(xx);
		return SUCCESS;
	}

自己看吧,红字是重点..不要有set和get方法....



然后就输入new.action.....成功...



没耐心讲了,写的不够详细..,呵呵...有问题mail我...
