Activemq5.13.2异常

我的系统是win8.1(64位的)下面是我用命令行打开bin\win64\activemq.bat时的报错,

在网上早了好多的解决办法,但都不行,我这个是5.13.2的,网上基本5.10的比较多,照着网上的办法,又是改计算机名——不能有中间横杆,又是改activemq.xml的,我试了试,还是不能正常启动。试了好久后,又觉得是jdk的路径名有问题,因为我一开始是D:\jdk1.8.0_40(这个是JAVA_HOME的)(PS网上说,要在环境变量的系统变量里设置CLASS_PATH、JAVA_HOME、path这些可以百度查)后来,我把jdk的名字改为jdk1.8.0.40,同时也把环境变量里的xx的用户变量和下面的系统变量里面有关jdk路径的设置的都改到D:\jdk1.8.0.40\(这只是JAVA_HOME的,其他的也就是吧jdk的名字改了),接着要重启下才行。

后来,再运行命令行,它就报了错:...java.lang.IllegalStateException: BeanFactory not initialized or already closed ...看着是Bean没启动。最后,我就试试看,把jdk改为用jdk1.7.0.21的,同上把环境变量里的也做了更改,再重启下,然后我运行了命令行win64\activemq.bat;魂淡,它居然就成功了…..最后的结果是这样的

总结,activemq5.13.2配的jdk应该用的是jdk1.7的,我做的更改,就是把计算机的名字改为纯英文的(没有中间横杆),jdk文件夹的名字也没有下划线或其他字符,环境变量里的系统变量里增加了下面几项:

CLASS_PATH:.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar

JAVA_HOME:D:\jdk1.7.0.21\

Path:D:\jdk1.7.0.21\bin(如果原来还在系统变量加path的,记得补上 “;C:\Windows\System32”,不然查不了ipconfig的)

哥能做的只有这么多了,原来有预想弄activemq可能网上解决文档难找,没想到这么稀缺,找了好久一堆雷同,就是没卵用。在此添上一点解决办法,希望有用。

Struts2框架有默认的类型转换错误拦截机制,该配置在struts-default.xml中,名叫conversionError,但是想使用需要继承ActionSupport. 默认的错误提示信息是英语的,若是想自定义,需要修改国际化文件: mess.properties: xwork.default.invalid.fieldvalue={0}字段类型转换失败! 对于对象的字段进行提示的话,需要使用局部action属性文件,并制定对应的字段名称 invalid.fieldvalue.user

ActiveMQ集群介绍 ActiveMQ具有强大和灵活的集群功能,但在使用的过程中会发现很多的缺点,ActiveMQ的集群方式主要由两种:Master-Slave(ActiveMQ5.8版本已不可用)和Broker Cluster. Broker集群 一个常见的场景是有多个 JMS broker ,有一个客户连接到其中一个 broker .如果这个 broker 失效,那么客户会自动重新连接到其它的 broker .在 ActiveMQ 中使用 failover:// 协议来实现这个功能.如果

java 19 - 6 throws的方式处理异常

1 /* 2 有些时候,我们是可以对异常进行处理的,但是又有些时候,我们根本就没有权限去处理某个异常. 3 或者说,我处理不了,我就不处理了. 4 为了解决出错问题,Java针对这种情况,就提供了另一种处理方案:抛出. 5 6 格式: 7 throws 异常类名1,异常类名2,... 8 注意:这个格式必须跟在方法的括号后面. 9 10 注意: 11 尽量不要在main方法上抛出异常. 12 但是我讲课为了方便我就这样做了. 13 (后面异常会跳转到页面中) 14 15 小结: 16 编译期异常

Atitit.异常的设计原理与&#160;策略处理&#160;java&#160;最佳实践&#160;p93

Atitit.异常的设计原理与 策略处理 java 最佳实践 p93 1 异常方面的使用准则,答案是::2 1.1 普通项目优先使用异常取代返回值,如果开发类库方面的项目,最好异常机制与返回值都提供,由调用者决定使用哪种方式..2 1.2 优先把异常抛出到上层处理..异常本身就是为了方便把异常情况抛出到上层处理..2 1.3 对于 HYPERLINK \l _Toc6222 方法调用结果异常情况返回策略,最终会有四种策略状况,2 1.4 返回null  还是异常??2 2 异常的由来与设计3 2

java Scanner和异常

Java Scanner 类 java.util.Scanner 是 Java5 的新特征,我们可以通过 Scanner 类来获取用户的输入. 下面是创建 Scanner 对象的基本语法: Scanner s = new Scanner(System.in); 接下来我们演示一个最简单的的数据输入,并通过 Scanner 类的 next() 与 nextLine() 方法获取输入的字符串,在读取前我们一般需要 使用 hasNext 与 hasNextLine 判断是否还有输入的数据: 使用 ne
