Spring Hibernate log4j AOP Bean

我这里所用的是struts-2.0.11.2,hibernate3.3.1,spring2.5.5不包版本之间可能有些包不同。

step1:首先新建一个web project项目，项目名为ssh2。

step2:首先把ssh2整合的环境搭建好再来写代码。

把所需要的JAR包复制到WebRoot/WEB-INF/lib目录下

struts2所需要的包:

struts2-core-2.0.11.jar

xwork-2.0.4.jar

ognl-2.6.11.jar

freemarker-2.3.8.jar

commons-logging-1.0.4.jar

struts2-spring-plugin-2.0.11.2.jar（这个是struts2和spring整合的包）

hibernate3.3所需要的包：

hibernate3.jar（这个是hibernate的核心包）

以及hibernate3/lib目录下所有的包复制进来，lib目录下有三个目录required，optional，bytecode其中required是hibernate必须的包，防为防止漏包，我们把另二个目录下的所有包也复制进来

Spring2.5所需要的包:

spring-framework-2.5.5\dist目录下的spring.jar这个是spring的核心包

spring-framework-2.5.5\lib\aspectj\aspectjrt.jar

spring-framework-2.5.5\lib\aspectj\aspectjweaver.jar

spring-framework-2.5.5\lib\c3p0\c3p0-0.9.1.2.jar

spring-framework-2.5.5\lib\log4j\log4j-1.2.15.jar

spring-framework-2.5.5\lib\jakarta-commons\commons-dbcp.jar

spring-framework-2.5.5\lib\jakarta-commons\commons-pool.jar

spring-framework-2.5.5\lib\jakarta-commons\commons-collections.jar

spring-framework-2.5.5\lib\jakarta-commons\commons-logging.jar

spring-framework-2.5.5\lib\jakarta-commons\commons-collections.jar

最后别忘了把mysql的数据库驱动包引进来，这里用的是MYSQL数据库

不知道写的时候有没有写漏，可能有一些包有重复，造成有冲突，解决方法，可以先把tomcat停止，然后在进到webapps/工程所有目录下的WEB-INF/lib下查看所有引入进来的JAR包，看到有复制的就删掉，只留下最新的。
step3:最后配置好的web.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee "
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance "
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd ">

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
  classpath:application-*.xml
</param-value>
</context-param>

<filter>
  <filter-name>struts2</filter-name>
  <filter-class>
   org.apache.struts2.dispatcher.FilterDispatcher
  </filter-class>
</filter>
<filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

<listener>
<listener-class>
  org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
  <param-name>encoding</param-name>
  <param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
    <welcome-file>reg.jsp</welcome-file>
</welcome-file-list>
</web-app>

src下struts.xml的最终代码如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd ">


<struts>
<package name="default" extends="struts-default">
  <action name="reg" class="reg">
   <result name="success">/regSuc.jsp</result>
   <result name="error">/regFail.jsp</result>
  </action>
</package>
</struts>
在src下把hibernate相应的配置文件复制进来，hibernate.cfg.xml最终代码如下：

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd ">

<hibernate-configuration>

<session-factory>
  <property name="hbm2ddl.auto">update</property>
  <property name="show_sql">true</property>
  <mapping resource="vo/User.hbm.xml" />
</session-factory>
</hibernate-configuration>

把hibernate缓存的配置也复制进来ehcache.xml代码如下：

</ehcache>
把hibernate下的日志文件配置复制过来log4j.properties：

# For JBoss: Avoid to setup Log4J outside $JBOSS_HOME/server/default/deploy/log4j.xml!
# For all other servers: Comment out the Log4J listener in web.xml to activate Log4J.
log4j.rootLogger=INFO, stdout, logfile

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

log4j.appender.logfile=org.apache.log4j.RollingFileAppender
log4j.appender.logfile.File=${petstore.root}/WEB-INF/petstore.log
log4j.appender.logfile.MaxFileSize=512KB
# Keep three backup files.
log4j.appender.logfile.MaxBackupIndex=3
# Pattern to output: date priority [category] - message

把spring的配置文件复制过来applicationContext.xml

这里我们把他改名为：applicaton-beans.xml最后代码为：

<?xml version="1.0" encoding="UTF-8"?>

<?xml version="1.0" encoding="UTF-8"?>

<bean id="propertyConfigurer"
  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  <property name="locations">
   <list>
    <value>classpath:jdbc.properties</value>
   </list>
  </property>
</bean>

<bean id="dataSource"
  class="org.apache.commons.dbcp.BasicDataSource">
  <property name="driverClassName"
   value="${jdbc.driverClassName}" />
  <property name="url" value="${jdbc.url}" />
  <property name="username" value="${jdbc.username}" />
  <property name="password" value="${jdbc.password}" />
</bean>

<bean id="sf"
  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <property name="dataSource" ref="dataSource" />
  <property name="configLocation"
   value="classpath:hibernate.cfg.xml" />
</bean>

<aop:config>
  <aop:advisor pointcut="execution(* *..PetStoreFacade.*(..))"
   advice-ref="txAdvice" />
</aop:config>
<tx:advice id="txAdvice" transaction-manager="txManager">
  <tx:attributes>
   <tx:method name="insert*" />
   <tx:method name="update*" />
   <tx:method name="delete*" />
   <tx:method name="modify*" />
   <tx:method name="*" read-only="true" />
  </tx:attributes>
</tx:advice>
<bean id="txManager"
  class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  <property name="dataSource" ref="dataSource" />
  </bean>
</beans>

到此，所有的配置都整合好了，下面开始写代码

step4:建立相应的jsp页面

注册页面reg.jsp代码如下：

<%@ page language="java" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <base href="<%=basePath%>">

    <title>SSH2用户注册</title>

<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

</head>

<body>
    <h2>用户注册</h2>
    <form action="reg.action " method="post">
    用户名：<input type="text" name="user.username " /><br />
    密  码：<input type="password" name="user.password "><br />
    <input type="submit" value="注册" /><input type="reset" value="重置" />
    </form>
</body>
</html>
注册成功显示页面regSuc.jsp代码如下：

<%@ page language="java" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <base href="<%=basePath%>">

    <title>注册成功</title>

<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

</head>

<body>
恭喜你注册成功了 <br>
</body>
</html>
注册失败regFail.jsp代码如下：

<%@ page language="java" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <base href="<%=basePath%>">

    <title>注册失败</title>

<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

</head>

<body>
对不起注册失败 <br>
</body>
</html>

在src下新建一个vo包，在vo包下新建一个User类，User.java代码如下：

package vo;

public class User {
private int id;
private String username;
private String password;
public String getUsername() {
  return username;
}
public void setUsername(String username) {
  this.username = username;
}
public String getPassword() {
  return password;
}
public void setPassword(String password) {
  this.password = password;
}
public int getId() {
  return id;
}
public void setId(int id) {
  this.id = id;
}

}
在vo包下新建hibernate的映射文件User.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd ">
<hibernate-mapping package="vo">
<class name="User" table="t_user">
  <id name="id">
   <generator class="native"></generator>
  </id>
  <property name="username" column="username" not-null="true"/>
  <property name="password" column="password" not-null="true"/>
</class>
</hibernate-mapping>

step5:编写struts2的action类，UserAction.java代码如下：

package action;

import vo.User;
import com.opensymphony.xwork2.ActionSupport;

import dao.UserDao;

public class UserAction extends ActionSupport {

private static final long serialVersionUID = -8534550171421612227L;
private User user;
private UserDao userDaoImpl;
public User getUser() {
  return user;
}
public void setUser(User user) {
  this.user = user;
}
public static long getSerialVersionUID() {
  return serialVersionUID;
}
@Override
public String execute() throws Exception {
  boolean flag = false;
  flag = userDaoImpl.insertUser(user);
  if(flag){
   return SUCCESS;
  }else{
   return ERROR;
  }
}
public UserDao getUserDaoImpl() {
  return userDaoImpl;
}
public void setUserDaoImpl(UserDao userDaoImpl) {
  this.userDaoImpl = userDaoImpl;
}
}
在src下新建一个dao包，在dao下新建一个UserDao.java
