# (in seconds)
cpool.maxIdleTimeExcessConnections=1800
# Acquiring new connections is slow, so eagerly retrieve extra connections
# when current pool size is reached
cpool.acquireIncrement=5
或者將上面的3部分寫成一個：
<bean id="c3p0DataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass">
<value>${jdbc.driverClassName}</value>

<property name="acquireIncrement"><value>5</value></property>
<property name="maxIdleTime"><value>10</value></property>
<property name="maxStatements"><value>0</value></property>
</bean>
如果使用的是受管理的J2EE服務器，則在spring中配置為JNDI連接：
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:comp/env/jndi/xxx</value>
</property>
</bean>
如果在應用里有獨自使用hibernate，則在spring中配置hibernate連接池，使用C3P0如下：
<bean id="DataSource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName">
<value>oracle.jdbc.driver.OracleDriver</value>
</property>
<property name="url">
<value>jdbc:oracle:thin:@172.16.20.241:1521:dbsvr</value>
</property>
<property name="username">
<value>hl3000</value>
</property>
<property name="password">
<value>hldw3101</value>
</property>
</bean>
<bean id="SessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="DataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<!-- C3P0連接池配置 -->
<prop key="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</prop>
<prop key="hibernate.c3p0.max_size">20</prop>
<prop key="hibernate.c3p0.min_size">5</prop>
<prop key="hibernate.c3p0.timeout">120</prop>
<prop key="hibernate.c3p0.max_statements">100</prop>
<prop key="hibernate.c3p0.idle_test_period">120</prop>
<prop key="hibernate.c3p0.acquire_increment">2</prop>
<prop key="myeclipse.connection.profile">hl3000</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>com/hl3000/DBLogic/POJO/PermUserAccount.hbm.xml</value>
</list>
</property>
</bean>
spring中配置獨立使用hibernate時使用jndi的配置：
hibernate.dialect = net.sf.hibernate.dialect.MySQLDialect
hibernate.connection.datasource=java:comp/env/jdbc/SAMPLEDB
hibernate.show_sql=true
如果是使用不受管理的Servlet容器如Tomcat，也可以使用jndi的方式配置，需要在tomcat中配置數據源，在server.xml中增改大致如下：
<Resource name="jdbc/testDb" auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/testDB">\\數據源的名稱
<parameter><name>username</name><value>root</value></parameter>數據庫的名稱
<parameter><name>password</name><value>password</value></parameter>數據庫密碼
<parameter><name>driverClassName</name>
<value>org.gjt.mm.mysql.Driver</value></parameter>\\要加載的驅動
<parameter><name>url</name>
<value>jdbc:mysql://172.20.0.73/rk?</value></parameter>\\要連接的URL
</ResourceParams>

修改web.xml：
作用是利用spring AOP將filter Proxy到web.xml里去，并攔截相關的request
<?xml version="1.0" encoding="UTF-8"?>

</filter-mapping>
...
</web-app>
二、身份驗證
WEB-INF下增加applicationContext-acegi-security.xml文件，并增加驗證服務所需要的filter：
web.xml中的FilterToBeanProxy將攔截的內容：
<bean id="filterChainProxy"
class="org.acegisecurity.util.FilterChainProxy">
<property name="filterInvocationDefinitionSource">
<value>
CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
PATTERN_TYPE_APACHE_ANT
/j_acegi_security_check*=httpSessionContextIntegrationFilter,authenticationProcessingFilter
/**/*=httpSessionContextIntegrationFilter,logoutFilter,
authenticationProcessingFilter,securityContextHolderAwareRequestFilter,
anonymousProcessingFilter,exceptionTranslationFilter,filterInvocationInterceptor
</value>
</property>
</bean>
<bean id="exceptionTranslationFilter"
class="org.acegisecurity.ui.ExceptionTranslationFilter">
<property name="authenticationEntryPoint">
<ref local="authenticationProcessingFilterEntryPoint" />
</property>
...
</bean>
<bean id="authenticationProcessingFilterEntryPoint"
class="org.acegisecurity.ui.webapp.AuthenticationProcessingFilterEntryPoint">
<property name="loginFormUrl">
<value>/login.jsp</value>
</property>
<property name="forceHttps">
<value>false</value>
</bean>
authenticationProcessingFilter就是進行身份驗證所用到的的filter，其主要是依靠authenticationManager來進行數據庫或文本文件上存放的注冊信息來進行核對：
<bean id="authenticationProcessingFilter"
class="org.acegisecurity.ui.webapp.AuthenticationProcessingFilter">
<property name="authenticationManager">
<ref bean="authenticationManager" />
</property>
<property name="authenticationFailureUrl">
<value>/login.jsp?login_error=1</value>
</property>
<property name="defaultTargetUrl">
<value>/</value>
</property>
<property name="filterProcessesUrl">
<value>/j_acegi_security_check</value>
</property>
</bean>
<bean id="authenticationManager"
class="org.acegisecurity.providers.ProviderManager">
<property name="providers">
<list>
<ref local="daoAuthenticationProvider" />
<ref local="anonymousAuthenticationProvider" />
</list>
</property>
</bean>
<bean id="daoAuthenticationProvider"
class="org.acegisecurity.providers.dao.DaoAuthenticationProvider">
<property name="userDetailsService"/><ref local="userDetailsService"/></property>
<property name="userCache">
...
</property>
</bean>
<bean id="userDetailsService"
class="org.acegisecurity.userdetails.memory.InMemoryDaoImpl">
<property name="userProperties">
<bean
class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="location"
value="/WEB-INF/users.properties" />
</bean>
</property>
</bean>
users.properties：
james=tom@1231,ROLE_TECHNICIAN
krishna=krish2341,ROLE_TECHNICIAN
smith=pravah@001,ROLE_ADMIN
三、權限驗證
在身份驗證后，通過權限驗證來決定哪些資源由擁有哪些權限的用戶使用，httpRequestAccessDecisionManager控制投票方式，exceptionTranslationFilter增加了如果權限驗證失敗后所轉到的處理頁面，logoutFilter定義登出后轉到首頁:
<bean id="filterInvocationInterceptor"
class="org.acegisecurity.intercept.web.FilterSecurityInterceptor">
<property name="authenticationManager">
<ref bean="authenticationManager" />
</property>
<property name="accessDecisionManager">
<ref local="httpRequestAccessDecisionManager" />
</property>
<property name="objectDefinitionSource">
<value>
PATTERN_TYPE_APACHE_ANT
/index.jsp=ROLE_ADMIN,ROLE_TECHNICIAN
/order/createOrder.jsp=ROLE_TECHNICIAN
/order/authorizeOrder.jsp=ROLE_ADMIN
/login.jsp=ROLE_ANONYMOUS,ROLE_TECHNICIAN,ROLE_ADMIN
</value>
</property>
</bean>
<bean id="exceptionTranslationFilter"
class="org.acegisecurity.ui.ExceptionTranslationFilter">
<property name="authenticationEntryPoint">
<ref local="authenticationProcessingFilterEntryPoint" />
</property>
<property name="accessDeniedHandler">
<bean
class="org.acegisecurity.ui.AccessDeniedHandlerImpl">
<property name="errorPage" value="/accessDenied.jsp" />
</bean>
</property>
</bean>
<bean id="httpRequestAccessDecisionManager"
class="org.acegisecurity.vote.AffirmativeBased">
<property name="allowIfAllAbstainDecisions">
<value>false</value>
</property>
<property name="decisionVoters">
<list>
<ref bean="roleVoter" />
</list>
</property>
</bean>
<bean id="roleVoter" class="org.acegisecurity.vote.RoleVoter" />
<bean id="logoutFilter"
class="org.acegisecurity.ui.logout.LogoutFilter">
<constructor-arg value="/index.jsp" />
<!-- URL redirected to after logout -->
<constructor-arg>
<list>
<bean
class="org.acegisecurity.ui.logout.SecurityContextLogoutHandler" />
</list>
</constructor-arg>
</bean>
至此，acegi配置部分完成，剩下相關頁面設計部分。

</servlet-mapping>
<servlet-mapping>
<servlet-name>SimpleUploader</servlet-name>
<url-pattern>/FCKeditor/editor/filemanager/upload/simpleuploader</url-pattern>
</servlet-mapping>
輸入的jsp文件類似如下：
<html:form action="/fck" method="post">
<fck:editor id = "fcktext" basePath = "/new1/FCKeditor/"
height = "100%"
skinPath = "/new1/FCKeditor/editor/skins/default/"
toolbarSet = "Default"
imageBrowserURL = "/new1/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector"
linkBrowserURL = "/new1/FCKeditor/editor/filemanager/browser/default/browser.html?Connector=connectors/jsp/connector"
flashBrowserURL = "/new1/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Flash&Connector=connectors/jsp/connector"
imageUploadURL = "/new1/FCKeditor/editor/filemanager/upload/simpleuploader?Type=Image"
linkUploadURL = "/new1/FCKeditor/editor/filemanager/upload/simpleuploader?Type=File"
flashUploadURL = "/new1/FCKeditor/editor/filemanager/upload/simpleuploader?Type=Flash" >
</fck:editor>
<html:submit/><html:cancel/>
</html:form>
其中的id是對應于ActionForm與validationv.xml里的property。分別類似如下：
String strfcktext = fckForm.getString("fcktext");
<form name="fckForm">
<field property="fcktext" depends="required">
<arg key="fckForm.fcktext"/>
</field>
</form>
另外需要注意的是，如果顯示找不到頁面的錯誤，應該是form里FCK相關的路徑設置不正確。數據庫段的字段也需要設置足夠大。如果傳輸過程里出現亂碼，可以所有jsp頁面加入：<%@ page language="java" contentType="text/html; charset=UTF-8"%>，在web.xml里加入u-f8 filter：
<!-- u-f8 filter -->
<filter>
<filter-name>encodingFilter</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>encodingFilter</filter-name>
<url-pattern>*.do</url-pattern>

首先，先創建一個顯示每一頁（有若干條數據）的方法（如下面的hfindAll方法），決定好每一頁接收一個頁碼參數，然后顯示該頁碼里的數據。比如有100條數據，那么分10頁，那第幾頁顯示第幾條至第幾條數據。然后再創建一個方法是用于在view層顯示頁數（如下面的amountPage方法），最后是在view層上為每一頁數的數字加上超鏈接。
以下是主要代碼：
public class LoginDAO extends HibernateDaoSupport {
private int PageSize =5;
/*設置每頁的數據條數*/
public Integer amountPage(){
Session session =this.getSession();
Query query = session.createQuery("from Login");
query.setCacheable(true);
int a = query.list().size()%PageSize;
/*總記錄數/每頁數據數,判斷是否能整除*/
Integer amount;
if(a!=0){
amount = query.list().size()/PageSize+1;
/*如果整除有余數，則頁數加1*/
}else{
amount = query.list().size()/PageSize;
/*如果整除沒余數，則直接總記錄數/每頁數據數*/
}
return amount;
}
public List hfindAll(String pagenum) {
Session session =this.getSession();
Query query = session.createQuery("from Login");
if (pagenum == null){
/*如果pagenum是空，則數據從第一條開始*/
query.setFirstResult(0);
/*設置查詢開始的第幾條數據，這里是從第1條開始*/
query.setMaxResults(PageSize);
/*設置查詢數據條數，這里是5條*/
query.setCacheable(true);
/*設置一級緩存*/
}else{
Integer p = (Integer.valueOf(pagenum)-1) * PageSize;
query.setFirstResult(p);
query.setMaxResults(PageSize);
query.setCacheable(true);
}
return query.list();
}
}
然后需要解決的是一些數據傳遞，類型轉換和在view層顯示的問題，主要代碼如下：
在ACTION里：
String strpagenum = request.getParameter("pagenum");
List results= loginManage.hfind(strpagenum);
Integer amountPage = loginManage.amountPage();
if(results!=null){
HttpSession session=request.getSession();
session.setAttribute("results",results);
session.setAttribute("amountPage",amountPage);
return mapping.findForward("ok");
}
return mapping.findForward("fail");
在view視圖里：
顯示每頁數據的代碼：
<logic:iterate id="element" name="results"> <tr>
<td width="100"><input type="checkbox" name="select" value="<bean:write name="element" property="id"/>"><bean:write name="element" property="id"/></td>
<td width="100"><bean:write name="element" property="name"/> </td>
<td width="100"><bean:write name="element" property="password"/></td>
</tr></logic:iterate>
顯示頁碼的代碼：
<%
int i;
int a=Integer.parseInt(session.getAttribute("amountPage").toString());
for (i=1;i<=a;i++){
out.println("<tr>");
out.println("<td><a href='display.do?pagenum="+ i +"'>"+ i +"</a></td>");
out.println("</tr>");
}
%>
]]>
那是因為有可能是你自己手動創建了session，比如：
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
然后調用：
Session session = sessionFactory.openSession();
Query query = session.createQuery("from Login");
類似這樣的單獨使用hibernate時的用法，是需要手工去關閉session的。沒有關閉的話就會收到那樣的警告。
所以最好是使用spring管理的session，和OpenSessionInViewFilter，比如：
Session session =this.getSession();
然后在web.xml里加入
<filter>
<filter-name>OpenSessionInViewFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
其中在spring里注冊的sessionfactory必須是id="sessionFactory"，如果是id="SessionFactory"或者其他，會提示sessionFactory沒有注冊的錯誤，因為OpenSessionInViewFilter里注冊的名必須為sessionFactory。

調用DAO：

批量刪除

Spring2.0 Hibernate3.1.x/Hibernate3.2
在使用Spring的AOP編程時，會用到這幾個lib：
asm-2.2.2.jar
asm-commons-2.2.2.jar
asm-util-2.2.2.jar
Hibernate如果使用lib：
asm.jar
asm-attrs.jar
其中asm-2.2.2.jar與asm.jar存在類上的沖突！！！
使用其中之一或兩者都使用，可能會出現如下錯誤：
java.lang.NoClassDefFoundError: org/objectweb/asm/CodeVisitor
java.lang.NoClassDefFoundError: org/objectweb/asm/commons/EmptyVisitor
java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit。。。。。。
解決辦法是：
1）.去掉類路徑上的關于Hibernate的3個lib
asm.jar
asm-attrs.jar
cglib-2.1.3.jar
2）.加入Spring中的以下4個lib
asm-2.2.2.jar
asm-commons-2.2.2.jar
asm-util-2.2.2.jar
cglib-nodep-2.1_3.jar
如果再不行，都試試刪刪看。
java.lang.SecurityException: class "javax.xml.bind.JAXBContext"'s signer information does not match signer information of other classes in the same package
這個錯誤是因為載入的包里面有兩個相同路徑的類，就是在一個包里面有兩個同名的類
有可能是將相同的包載入兩次或者把包解開后，先將jar文件載入了，后又將解開的類載入了
Error configuring application listener of class org.springframework.web.context.ContextLoaderListener
試試自己去下一個spring的包，把包里的spring.jar加到項目里去。eclipse生成的時候可能會有些包沒有放進去。
Error creating bean with name 'datasource' defined in file
Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool
試試將commons-dbcp.jar，commons-pool.jar和commons- collections.jar加入CLASSPATH中
hibernate 3.1 中的hibernateTemplate ，class應該為org.springframework.orm.hibernate3.HibernateTemplate，而非org.springframework.orm.hibernate.HibernateTemplate，因為某些原因我現在還用3.1，早前在玩springside的時候感覺hibernate 3.2 的Hibernate Annotations方便多了。
找不到action或報錯的另一少有原因，一些版本hibernate版本會有些沖突方面的問題，可換一版本的hibernate試試，個人感覺hibernate的版本對應用會比較敏感
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in resource [/WEB-INF/dataAccessContext-hibernate.xml] of ServletContext: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/transaction/TransactionManager
java.lang.NoClassDefFoundError: javax/transaction/TransactionManager
原因：缺少jta.jar 或者是找不到hbm.xml文件導致sessionfactory出錯,檢查hbm文件路徑是否正確,文件是否存在
<property name="mappingResources">
<list>
<value>com/yourcompany/model/Login.hbm.xml
</value>
</list>
</property>
2007-06-26 18:38:13,671 ERROR [com.yourcompany.model.dao.LoginDAO] - <save failed>

java.sql.SQLException: Table 'mysql.mysql__login' doesn't exist
把hbm文件里面的catalog="'mysql"去掉即可！
另注意的一點是eclipse生成的DAO文件應該是：
public void save(Login transientInstance) {
log.debug("saving Login instance");
try {
getHibernateTemplate().save(transientInstance);
log.debug("save successful");
} catch (RuntimeException re) {
log.error("save failed", re);
throw re;
}
}
而不是原來的 public void save(LoginDAO transientInstance)
只要在applicationContext.xml中加上
<property name="mappingResources">
<list>
<value>com/yourcompany/hibernate/Users.hbm.xml</value>
</list>
</property>
加這段代碼就會找不到action
換一個版本的hibernate應該就ok
Invalid path /addcustomer was requested
輸入的路徑不正確，檢查spring中注冊的action的路徑和輸入的路徑是否一致，留意大小寫是否一致

<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring/*.xml</param-value>
</context-param>
這樣將web層和service層的配置分開擺放，看起來比較清晰。具體可參考springside的example
另一方法是struts-config中直接寫 <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="classpath*:spring/*.xml"/>
</plug-in>
這樣將所有的配置文件直接放在spring目錄下
或小型應用可簡單寫成最直接的<plug-in className= "org.springframework.web.struts.ContextLoaderPlugIn"> <set-property property= "contextConfigLocation" value="/WEB-INF/applicationContext.xml"/>
不過多句提醒下記得不要漏了web.xml中還應有 <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
struts-config.xml中還應有：
<controller>
<set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/>
</controller>

說明你的log4j.properties沒有配置。請把log4j.properties放到工程的classpath中，eclipse的classpath為bin目錄，由于編譯后src目錄下的文件會拷貝到bin目錄下，所以你可以把log4j.properties放到src目錄下。
這里給出一個log4j.properties的例子：
log4j.rootLogger=DEBUG,stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %5p (%F:%L) - %m%n
在spring中如何配置的log4j
在web.xml中加入以下代碼即可。
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/log4j.properties</param-value>
</context-param>
