annotationssh零配置BaseDao拦截器 
阅读更多

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://www.springsource.org/download/community

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-2.3.1.1.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

<!-- spring 配置 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <description>Spring上下文</description>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext*.xml</param-value>
  </context-param>

<!-- hibernate 懒加载的问题过滤 ,可以不配置 -->
  <filter>
    <description>hibernate Session 过滤器</description>
    <filter-name>openSessionInViewFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>openSessionInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <filter> 
 <!-- struts配置 -->
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

 

struts.xml配置

<struts>

<!-- 使用Spring -->
 <constant name="struts.objectFactory" value="spring" />
 <constant name="struts.devMode" value="true" />
 <constant name="struts.configuration.xml.reload" value="true" />
 
 <package name="default" extends="struts-default" namespace="/">
  <interceptors>
   <!-- 使用权限拦截 -->
   <interceptor name="authority" class="com.sshFrame.zero.interceptor.AuthorityInterceptor"/>
   <!-- 异常拦截 -->
   <interceptor name="exceptionInterceptor" class="com.sshFrame.zero.interceptor.ExceptionInterceptor"/>
   <!-- 解决struts安全漏洞，拦截所有的带有#号的url -->
   <interceptor-stack name="baseStack">
    <interceptor-ref name="authority"/>
    <interceptor-ref name="exceptionInterceptor"/>
    <interceptor-ref name="params">   
     <param name="excludeParams">.*\\u0023.*</param>   
    </interceptor-ref>
    <interceptor-ref name="defaultStack"/>
   </interceptor-stack>
  </interceptors>
  <!-- 配置默认拦截器栈 -->
  <default-interceptor-ref name="baseStack"/>
  <global-results>
   <result name="login">/index.jsp</result>
   <result name="error">/error.jsp</result>
  </global-results>
 </package>

</struts>

 applicationcontext.xml配置：

我想问一下为什么service调用dao的时候，一定要加@Autowired呢？不加就空指针，能解释一下吗？

自动注入，dao，主要把当前注入的到给basedao，否则，basedao为null
