同事配置Spring security 2，使用Ehcache 緩沖時(shí)出現(xiàn)如下錯(cuò)誤
Caused by: java.lang.NoSuchMethodError: net.sf.ehcache.Cache.<init>(Ljava/lang/String;ILnet/sf/ehcache/store/MemoryStoreEvictionPolicy;ZLjava/lang/String;ZJJZJLnet/sf/ehcache/event/RegisteredEventListeners;Lnet/sf/ehcache/bootstrap/BootstrapCacheLoader;I)V

Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.userdetails.jdbc.JdbcUserDetailsManager#0.caching': Cannot resolve reference to bean 'userCache' while setting bean property 'userCache'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userCache' defined in ServletContext resource [/WEB-INF/spring-security.xml]: Cannot resolve reference to bean 'userEhCache' while setting bean property 'cache'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userEhCache' defined in ServletContext resource [/WEB-INF/spring-security.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: net.sf.ehcache.Cache.<init>(Ljava/lang/String;ILnet/sf/ehcache/store/MemoryStoreEvictionPolicy;ZLjava/lang/String;ZJJZJLnet/sf/ehcache/event/RegisteredEventListeners;Lnet/sf/ehcache/bootstrap/BootstrapCacheLoader;I)V

原因:使用ehcache-1.3.0.jar或者ehcache-1.5.0.jar替換 ehcache-1.2.3.jar
還需 backport-util-concurrent-3.1.jar
不然會(huì)報(bào)：java.lang.ClassNotFoundException: edu.emory.mathcs.backport.java.util.concurrent.Exe cutionException

StrutsUtils 未定義

同事遇到“StrutsUtils 未定義”錯(cuò)誤
struts2.1.6
s:optiontransferselect
沒(méi)有加載 Struts2 js

已加 <s:head />
源文件生產(chǎn)：
<script src="/xxxx/struts/utils.js" type="text/javascript"></script>

原因：
web.xml中
Struts沒(méi)攔截js文件,需加如：

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.js</url-pattern>
</filter-mapping>

JBPM4 4.0 使用問(wèn)題 -- 2: jbpm 4 在Tomcat 6.0上運(yùn)行問(wèn)題

have different Class objects for the type javax/el/ExpressionFactory used in the signature

使用Tomcat發(fā)布時(shí),需將jurl.jar,jurl-engine.jar,jurl-impl.jar替換Tomcat安裝目錄lib下的el-api.jar

JBPM4 4.0 使用問(wèn)題 -- 1:結(jié)合Sqlserver使用問(wèn)題

驚嘆JBPM的更新速度
項(xiàng)目要使用工作流引擎
談需求時(shí)JBPM 4.0還是beta版，現(xiàn)在我們需求談好，JBPM 4.0也已經(jīng)出到GA版
JBPM 4與3的差別相當(dāng)大......，看來(lái)JBPM自己已經(jīng)拋棄了3，我們項(xiàng)目也沒(méi)必要猶豫了，選4吧~
下載地址：
http://downloads.sourceforge.net/project/jbpm/a%29%20jBPM%204/jbpm-4.0/jbpm-4.0.zip?use_mirror=nchc

1:JBPM 4 DB 里居然沒(méi)有 Sql server ，難道不支持Sqlserver。
因?yàn)镴BPM 4使用Hibernate，不支持Sqlserver可能性不大，所以自己寫相應(yīng)的create.sql drop.sql 及 hibernate配置文件。
測(cè)試可以通過(guò)。

但還是遇到些許問(wèn)題..
A：org.hibernate.exception.ConstraintViolationException: could not insert: [org.jbpm.pvm.internal.history.model.HistoryProcessInstanceImpl]
Caused by: java.sql.SQLException: 當(dāng) IDENTITY_INSERT 設(shè)置為 OFF 時(shí)，不能為表 'JBPM4_HIST_PROCINST' 中的標(biāo)識(shí)列插入顯式值。
JBPM4_HIST_PROCINST ： DBID_ bigint not null IDENTITY, 改為 DBID_ bigint not null
經(jīng)查系改Sql時(shí)沒(méi)看仔細(xì),該表非IDENTITY id。

B：org.hibernate.exception.ConstraintViolationException: could not insert: [org.jbpm.pvm.internal.model.ExecutionImpl]
Caused by: java.sql.SQLException: 違反了 UNIQUE KEY 約束 'UQ__JBPM4_EXECUTION__7D8391DF'。不能在對(duì)象 'dbo.JBPM4_EXECUTION' 中插入重復(fù)鍵。

ID_ ASC
Note that SQL Server doesn't allow multiple null values in a column with
a unique constraint (JBPM4_EXECUTION.ID_).
忍痛去掉該約束~

2：待續(xù)~

RMI其實(shí)發(fā)布成功了...
為什么開(kāi)始有錯(cuò)呢？
查看源代碼發(fā)現(xiàn)：其實(shí)是Spring的Debug log
他會(huì)先看有沒(méi)rmi注冊(cè)

org.springframework.remoting.rmi.RmiServiceExporter.testRegistry(RmiServiceExporter.java:411)

沒(méi)有l(wèi)og下再

Could not detect RMI registry - creating new one

所以屏蔽該Log4j配置文件中加如：

log4j.logger.org.springframework.remoting.rmi.RmiServiceExporter=INFO

What's new in DWR v3

View more presentations from Joe Walker.

在我看來(lái)最有用的要屬:Reverse ajax 反轉(zhuǎn)Ajax的變更了.
DWR2 時(shí),一般這樣使用:
ScriptBuffer script = new ScriptBuffer();
script.appendScript("alert(1)");
ServerContext sctx = ServerContextFactory.get(servletContext ); //FIXME WCTX
if(sctx!=null)
{
Collection<ScriptSession> pages = sctx.getScriptSessionsByPage("/HustMes/pages/menu/pbsZoneLayoutAction.action");
);
for (ScriptSession session : pages)
{
  session.addScript(script);
}
}

并且如果是非頁(yè)面調(diào)用的話要給類注入 servletContext

現(xiàn)在簡(jiǎn)單多了,不管頁(yè)面調(diào)用還是其他如WebService調(diào)用只需:
String page = ServerContextFactory.get().getContextPath() + "xxx.jsp";
Browser.withPage(page,new Runnable() {
         public void run() {
    ScriptSessions.addScript("alert(1)");
         }
});
其他方法的使用,請(qǐng)參照API..

Spring Aop 注意...

在使用Spring Aop的時(shí)候,有時(shí)會(huì)攔截不到希望攔截的方法...

有時(shí)2.0可以但2.5卻不可以~

Spring Aop 代理有兩種:Java動(dòng)態(tài)代理和Cglib代理

一般我用的是Cglib代理..<aop:config proxy-target-class="true">

只要在被spring攔截的方法中再調(diào)用其他被代理的對(duì)象的方法就可以實(shí)現(xiàn)嵌套攔截,

如果調(diào)用自己對(duì)象的方法（包括繼承的）,

只是普通對(duì)象的方法調(diào)用（這時(shí)自己是被剝?nèi)チ舜淼臍さ脑紝?duì)象）,

是不能被攔截的。

Debug下,看一下是不是proxy的類,被proxy的才有可能被攔截..

另外: 使用groovy時(shí),不能對(duì)注入groovy Bean的java類進(jìn)行AOP.(接口編程)

會(huì)報(bào)以下錯(cuò)誤:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messenger': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Could not generate CGLIB subclass of class [class $Proxy74]: Common causes of this problem include using a final class or a non-visible class; nested exception is java.lang.IllegalArgumentException: Cannot subclass final class class $Proxy74

Myeclipse7 安裝不上 GroovyEclipse Plugin 原來(lái)...

在網(wǎng)上下了 Groovy Eclipse 插件

但怎么都不出來(lái)～

Groovy Eclipse 官網(wǎng)顯示支持Eclipse3.4

后來(lái)發(fā)現(xiàn)：

org.testng.eclipse,5.7.0.1,file:/E:\Genuitec\kimplug\GroovyEclipse\plugins\org.testng.eclipse_5.7.0.1\,4,false

這句 Myeclipse 自帶testing ng......

將這句刪掉OK了 ......
