本文详细介绍了如何使用SSH框架进行全注解配置，并与Spring、Hibernate进行整合，包括配置Spring和Hibernate注解，实现Struts、Spring、Hibernate的注解驱动，以及如何使用通配符配置Result。

SSH全注解-annotation详细配置 [url]http://www.iteye.com/topic/816574[/url]
使用 Spring 2.5 注释驱动的 IoC 功能 [url]https://www.ibm.com/developerworks/cn/java/j-lo-spring25-ioc/[/url]
只是参考.

先根据[url]http://panyongzheng.iteye.com/blog/1103591[/url]配置好无注解，然后在根据下面的设定来实现全注解。当然，你可以只直接Spring和Hibernate，Struts.xml的东西依然保存。这个看你喜欢。

[b]@Results也可以用于整个Action注解，跟在@ParentPackage("struts-default") 注解的后面，那么这个@Result就相对应整个类。[/b]

[b]1.只注解Sprint & Hibernate的内容。
2.Struts,Spring,Hibernate全部注解。
3.使用通配符配置result。

struts.xml,class定义的Action，应该跟Spring的注解@Controller("LoginAction")对应。

[color=red]2.[b]Struts一并使用注解[/b]:[/color]
修改web.xml
<filter>
	  	<filter-name>struts2</filter-name>
	  	<filter-class>
	  		org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
	  	</filter-class>
	  	<init-param>  
        	<param-name>actionPackages</param-name>  
        	<param-value>com.action,com.actionother</param-value>  
       </init-param> 
	  </filter>
	  <filter-mapping>
	  	<filter-name>struts2</filter-name>
	  	<url-pattern>/*</url-pattern>
	  </filter-mapping>


去掉struts.xml的配置:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
</struts>


Action.java增加一些注解:
package com.action;

import java.util.List;

import javax.annotation.Resource;

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.springframework.stereotype.Controller;

import com.opensymphony.xwork2.ActionSupport;
import com.service.impl.TestTableService;

@Controller("LoginAction")
@Namespace("/")
@ParentPackage("struts-default")
public class LoginAction extends ActionSupport {

	/**
	 * 
	 */
	private static final long serialVersionUID = -6434128483294080524L;
	@Resource(name="TestTableService")
	public TestTableService service;
	private String userName;
	private String userPassword;


	@Override
	@Action(value="/login",
		results={
			@Result(name="success",location="/index.jsp"),
			@Result(name="input",location="/login.jsp")
			}
	)
	public String execute() throws Exception {

		System.out.println("Call from action.");
		List list = service.list();
		System.out.println(list.size());
		return super.SUCCESS;
	};

	@Override
	public void validate() {
		System.out.println(getText("test.i18n"));
	};






	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getUserPassword() {
		return userPassword;
	}
	public void setUserPassword(String userPassword) {
		this.userPassword = userPassword;
	}

	public TestTableService getService() {
		return service;
	}

	public void setService(TestTableService service) {
		this.service = service;
	}
}


[color=red][b]或者换一种配置[/b][/color]:
struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
	<package name="struts2" extends="struts-default" namespace="/">
	</package>
</struts>



Action.java
@Controller("LoginAction")/*这里是可以省略的*/
@ParentPackage("struts2")
/*
   @Result可以在这里配置。
*/
public class LoginAction extends ActionSupport {
      ......
      ......
}



[color=red][b]3.使用通配符配置Result[/b]:[/color]
@Override
	@Action(value="/*PageAction"
		,results={
				@Result(name="success",location="/{1}.jsp")
			}
	)
	public String execute() throws Exception {
		// TODO Auto-generated method stub
		//return super.execute();
		System.out.println("@@ Call-->PageAction");
		return "success";
	}

调用Aciton的URL： indexPageAction.action
