ssh(struts2.3.8+spring3.2+heibernate4.1+annotation零配置
公司一直不是ssh零配置的框架，每次写action都要在applicationcontext和struts里面配置，好麻烦，最近有空，写了一个ssh零配置的框架
这里写了一个小的项目，以用户权限管理为例
先做准备工作：
1.struts2去官网下载最新版struts开发包http://struts.apache.org/download.cgi#struts216
2.hibernate4去官网下载最新版hibernate4开发包http://sourceforge.net/projects/hibernate/files/hibernate4/
3.spring3去官网下载最新版spring3开发包http://maven.springframework.org/release/org/springframework/spring/
一、先建立一个空的web的项目sshFrame，加载必须的包
1.添加struts2必备的包。我下载的是最近的struts2.3.8
asm-3.3.jar --ASM字节码库 ，使用“cglib”则必要
aopalliance-1.0.jar --这个包为AOP提供了最普通和通用的接口
commons-fileupload-1.2.2.jar --Struts2上传下载的jar
commons-io-2.0.1.jar --Struts2上传下载的jar
commons-logging-1.1.1.jar --Jakarta的通用日志记录包
freemarker-2.3.19.jar
ognl-3.0.6.jar --支持ognl表达式
struts2-core-2.3.8.jar --struts2的核心包
struts2-spring-plugin-2.3.8.jar --struts2与spring整合所需
struts2-convention-plugin-2.3.8.jar --struts2零配置注释用
xwork-core-2.3.8.jar
可以不加 struts2-config-browser-plugin-2.3.8.jar为struts协助开发需要的包：可以输入http://127.0.0.1:8686/config-browser/actionNames.action查看系统所有已经存在的action,配置不正确就可以在这里看出来;
2.添加Hibernate 所需要的包。hibernate-4.1.9.Final
把下载下来的hibernate\lib\required下的包全部拷贝进去，分别是
antlr-2.7.7.jar --语言转换工具，hibernate用他将hql语句转换为sql语句
dom4j-1.6.1.jar --解析xml文档的工具
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-core-4.1.9.Final.jar --核心包
hibernate-jpa-2.0-api-1.0.1.Final.jar
javassist-3.17.1-GA.jar
jboss-logging-3.1.0.GA.jar
jboss-transaction-api_1.1_spec-1.0.0.Final.jar
还有加入hibernate\lib\optional\c3p0\c3p0-0.9.1.jar
hibernate-ehcache-4.1.9.Final.jar
ehcache-core-2.4.3.jar
slf4j-api-1.6.4.jar
slf4j-log4j12-1.6.4.jar
3添加spring3 所需要的包 spring-framework-3.2.0.RELEASE
spring-aop-3.2.0.RELEASE.jar
spring-aspects-3.2.0.RELEASE.jar
spring-beans-3.2.0.RELEASE.jar
spring-context-3.2.0.RELEASE.jar
spring-core-3.2.0.RELEASE.jar
spring-expression-3.2.0.RELEASE.jar
spring-instrument-3.2.0.RELEASE.jar
spring-jdbc-3.2.0.RELEASE.jar
spring-jms-3.2.0.RELEASE.jar
spring-orm-3.2.0.RELEASE.jar
spring-oxm-3.2.0.RELEASE.jar
spring-test-3.2.0.RELEASE.jar --测试时用
spring-tx-3.2.0.RELEASE.jar --事务处理所用
spring-web-3.2.0.RELEASE.jar
aspectjweaver-1.5.3.jar --spring所依赖的包
其他
asm-commons-3.3.jar
Commons—pool.jar ,commons-dbcp.jar ----------DBCP数据库连接池，Apache的jakarta组织开发 的，tomcat连接池也是dbcp（可选）
cglib.jar----------------------------高效的代码生成工具, Hibernate用它在运行时扩展 Java类和实现 Java 接
jta.jar --标准的JTA API(JTA即java事物API，JTA事务比JDBC事务更强大。一个JTA事务可以有多个参与者，而一个JDBC事务则被限定在一个单一的数据库连接)，我暂时还没加，先备着
mysql-connector-java-5.1.18-bin.jar
log4j-1.2.16.jar
二、添加配置文件
在struts包下struts\src\apps\blank\src\main\resources提供了空白的struts.xml文件，把它复制到项目的src下
web.xml中
org.springframework.web.context.ContextLoaderListener
Spring上下文
contextConfigLocation
classpath:applicationContext*.xml
hibernate Session 过滤器
openSessionInViewFilter
org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
openSessionInViewFilter
/*
struts2
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
struts2
/*
struts.xml配置
.*\\u0023.*
/index.jsp
/error.jsp
applicationcontext.xml配置：
org.hibernate.dialect.MySQLDialect
thread
org.hibernate.cache.EhCacheRegionFactory
true
true
update
com.sshFrame.zero.pojo
com.sshFrame.test.pojo
三、写框架基类
改写基本的框架类了
Basedao

/**

六、加入拦截器
package com.sshFrame.zero.interceptor;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;
import com.sshFrame.zero.action.users.UserinfoAction;
import com.sshFrame.zero.exception.AhCustomException;
import com.sshFrame.zero.exception.AhCustomException.ExcCode;
/**
* 用户权限拦截器，在struts.xml中配置
* @author 雪精灵
*/
public class AuthorityInterceptor extends AbstractInterceptor{
private static final long serialVersionUID = 2914081148619842225L;
private UserinfoAction userinfoAction;
@Override
public String intercept(ActionInvocation invocation) throws Exception {
HttpServletRequest request = ServletActionContext.getRequest();
// String method = invocation.getProxy().getMethod();
// String actionName=invocation.getInvocationContext().getName();
String userid = (String) request.getSession().getAttribute("userid");
if(userid==null||"".equals(userid)){
request.setAttribute("msg",AhCustomException.getExcMessage(ExcCode.Unlogined));
return Action.ERROR;
}
//获取项目路径
String contextPath=request.getServletContext().getContextPath();
//获取当前路径
String uri = request.getRequestURI();
//当前相对项目的路径
String actionUrl=uri.replace(contextPath, "");
boolean used = userinfoAction.used(userid, actionUrl);
if(used){
return invocation.invoke();
}else{
request.setAttribute("msg",AhCustomException.getExcMessage(ExcCode.InvalidRights));
return Action.ERROR;
}
}
public UserinfoAction getUserinfoAction() {
return userinfoAction;
}
public void setUserinfoAction(UserinfoAction userinfoAction) {
this.userinfoAction = userinfoAction;
}
}
package com.sshFrame.zero.interceptor;
import javax.servlet.http.HttpServletRequest;
import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;
import org.hibernate.HibernateException;
import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;
import com.sshFrame.zero.exception.AhCustomException;
import com.sshFrame.zero.exception.AhCustomException.ExcCode;
/**

*/
public class ExceptionInterceptor extends AbstractInterceptor{
private Logger logger=Logger.getLogger(ExceptionInterceptor.class);
private static final long serialVersionUID = -3490533736557683231L;

HttpServletRequest request = ServletActionContext.getRequest();

try {

} catch (HibernateException e) {
e.printStackTrace();
logger.error("异常拦截器拦截到异常:"+"

excMessage=AhCustomException.getExcMessage(ExcCode.DataProcessing);
request.setAttribute("msg", excMessage);
result=Action.ERROR;
}catch (NullPointerException e) {
e.printStackTrace();
logger.error("异常拦截器拦截到异常:"+"

}
return result;
}
}七、自定义异常类
package com.sshFrame.zero.exception;
/**
* 自定义异常处理
* @author 雪精灵
*/
public class AhCustomException extends Exception{
private static final long serialVersionUID = 1L;
/**
* 错误类型标识
*/
private ExcCode excCode = null;
public enum ExcCode{
AppError,
InvalidRights,
IllegalData,
DataProcessing,
Unlogined
}
public static final String[] excMessage = {
"内部异常",
"您没有执行本操作的权限",
"提供的数据为空或不合法",
"数据处理异常",
"您可能还没有登录本系统，或者已经超时，您必须先登录本系统后才能使用该功能"
};
public AhCustomException(){
super(getExcMessage(ExcCode.AppError));
excCode = ExcCode.AppError;
}
/**
* 构造函数
*
* @param arg0
* 错误类型标识
*/
public AhCustomException(ExcCode excCode) {
super(getExcMessage(excCode));
this.excCode = excCode;
}
/**
* 根据错误类型标识获取错误信息
*
* @param emFlag
* 错误类型标识
*
* @return 错误信息
*/
public static String getExcMessage(ExcCode excCode) {
return excMessage[excCode.ordinal()];
}
public String getExcMessage() {
return excMessage[excCode.ordinal()];
}
/**
* 构造函数
*
* @param arg0
* 错误类型标识
*
* @param arg1
* 被包含的异常对象
*/
public AhCustomException(ExcCode excCode, Throwable throwable) {
super(getExcMessage(excCode), throwable);
setStackTrace(throwable.getStackTrace());
this.excCode = excCode;
}
/**
* 构造函数
*
* @param arg0
* 被包含的异常对象
*/
public AhCustomException(Throwable throwable) {
super(getExcMessage(throwable.getClass() == AhCustomException.class ? ((AhCustomException) throwable).excCode : ExcCode.AppError), throwable);
setStackTrace(throwable.getStackTrace());
if (throwable.getClass() == AhCustomException.class)
excCode = ((AhCustomException) throwable).excCode;
else
excCode = excCode.AppError;
}
}八、页面
index.jsp,在webContent下
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
My JSP 'index.jsp' starting page
${msg }
init.jsp.在web-inf/content/下
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
My JSP 'init.jsp' starting page
