我是Spring和hibernate的新手,所以我试图实现一些基于Spring 3 + hibernate 4的简单Web应用程序,而我启动tomcat时遇到这个异常:

java.lang.NoClassDefFoundError: org/hibernate/cache/CacheProvider
at java.lang.Class.getDeclaredMethods0(Native Method)
at java.lang.Class.privateGetDeclaredMethods(Class.java:2427)
at java.lang.Class.getDeclaredMethods(Class.java:1791)
    ...
Caused by: java.lang.ClassNotFoundException: org.hibernate.cache.CacheProvider
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1678)
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1523)

我发现这个类在hibernate 3的hibernate-core中,但是我没有在hibernate 4中找到它.

我的context.xml中用于持久化的部分:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
    <property name="url" value="jdbc:oracle:thin:@IP_Address:SID"/>
    <property name="username" value="xxx"/>
    <property name="password" value="xxx"/>
    <property name="initialSize" value="5"/>
    <property name="maxActive" value="20"/>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.huawei.vms.user"/>
    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.Oracle10gDialect</prop>
        </props>
    </property>
</bean>

请帮我弄清楚它为什么要加载CacheProvider,因为我在context.xml中没有任何设置,我必须在我的项目中添加哪个jar.谢谢!

众所周知,表情符号最多可编码为3或4个字节,因此它可能会占用我的字符串中的2个符号.例如'wew'.length = 7我想在我的文本中找到这些符号,并将它们替换为依赖于其代码的值.读SO,我带着unicode插件来到XRegExp库,但还没找到如何使它工作的方法.

var str = 'wew';// \u1F601 symbol
var reg = XRegExp('[\u1F601-\u1F64F]', 'g'); //  /[?1-?F]/g -doesn't make a lot of sense  
//var reg = XRegExp('[\uD83D\uDE01-\uD83D\uDE4F]', 'g'); //Range out of order in character class
//var reg = XRegExp('\\p{L}', 'g'); //doesn't match my symbols
console.log(XRegExp.replace(str, reg, function(match){
   return encodeURIComponent(match);// here I want to have smth like that %F0%9F%98%84 to be able to map anything I want to this value and replace to it
}));

的jsfiddle

我真的不想强行查找我的范围内的字符序列.有人可以帮我找到用regexp做的方法.

EDITED刚想 出了一个枚举所有表情符号的想法.比野蛮力更好,但仍然在寻找更好的主意

var …

我知道最后在deamon线程中的块不会被执行.但是我一丝不苟地试图理解为什么以及JVM中发生的事情如此特殊以至于无法调用此块下的代码.

我认为它以某种方式与调用堆栈有关,它不能放松,但不知道如何.有人可以对此有所了解.谢谢.

我试图从Moxy转移到杰克逊json媒体提供商为我的泽西岛网络服务,发现了迄今为止我无法解决的几个问题:

首先,moxy对于同一段代码工作正常,但因为我们在其他项目中使用jackson,我希望保持一致......所以我改变了

1)对pom的依赖

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jackson</artifactId>
    <version>${jersey.version}</version>
</dependency>

2)ResourceConfig regester

register(JacksonFeature.class)

但是当我运行我的webservice时,我开始得到这个异常(基本上当我从Web服务方法返回时会发生这种情况):

尝试进入角度2，对角度1有一些经验并且有一些困惑。

我制作了一个共享模块：

import { NgModule }      from '@angular/core';
import { CommonModule }        from '@angular/common';

import { Constants }   from './injectables/constants';
import { Utils } from "./injectables/utils";
import { HighlightDirective } from "./directives/highlight";

@NgModule({
    imports: [ CommonModule ],
    declarations: [ HighlightDirective ],
    providers: [ Constants, Utils ],
    exports: [ HighlightDirective ]
})
export class VCommonModule { }

如果我错了，请纠正我，但是据我了解，这里仅需要导出指令，管道和组件？在我将此模块包含到AppModule的导入中之后，可以立即使用Services（Injectables）吗？所以我做到了：

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpModule } from '@angular/http';
import { VCommonModule } from …
