Eclipse 3.5.2不会在断点处停止.就像调试器使用旧版本的源文件一样.

尝试了通常的刷新,清理所有项目,构建所有项目,没有任何变化.

已经处于调试模式并检查断点.

*ok最终删除整个项目并再次检出.但仍然好奇这个问题是什么.

知道为什么我的Eclipse没有启动吗？

将eclipse.ini有以下几点:

-startup plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.0.v20100503
-product org.eclipse.epp.package.jee.product
--launcher.defaultAction openFile
--launcher.XXMaxPermSize 256M
-showsplash org.eclipse.platform
--launcher.XXMaxPermSize 256m
--launcher.defaultAction openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m

工作空间日志文件中的错误日志显示了这一点

你能在速度模板中做这样的事情吗？

#set ($map = $myobject.getMap() )
#foreach ($mapEntry in $map.entrySet())
    <name>$mapEntry.key()</name>
    <value>$mapEntry.value()</value>
#end

它会像这样输出空白标签:

<name></name> 

和

<value></value> 

我究竟做错了什么？

有没有办法在Oracle中创建一个时间戳列,自动存储记录更改时间的时间戳？

我正在使用3按钮UISegmented控件进行选择.我还有一个保存按钮,用于检索所选控件.

单击保存按钮时,我想要清除UISegmentedcontrol(即未选择上一个选定的按钮).我不是在寻找setMomentary,因为我希望选择能够坚持,但也可以在以后取消选择.

从has_secure_password用户对象进行交互时,从设置迁移会导致控制台中出现以下错误:

.rvm/gems/ruby-2.4.1/gems/devise-4.4.0/lib/devise/models/database_authenticatable.rb:166:in `password_digest'

我理解这是因为devise使用了这个pasword_digest函数,所以它与's 使用的password_digest列不兼容.active recordhas_secure password

解决方案是password_digest从数据库中删除列,但我不想丢失现有用户的密码.

我应该删除encrypted_password创建的列设计,然后进行迁移以重命名password_digest为encrypted_password然后更新现有用户的密码,还是有更合适的解决方案？

当我将窗口大小调整为中等大小时,右侧的两个链接会折叠并导致导航栏占用两行,即使右侧链接和左侧链接之间有足够的空间.

错误是:

读取或写入文件{0}时发生异常由于尚未设置Axis2运行时位置,因此无法安装Axis2构面.转到"Web服务"首选项页面,并在"Axis2首选项"下设置Axis2运行时位置.

在提到的首选项中,位置设置正确,实际上,在加载正确的运行时位置后,它表示"Axis2运行时已成功加载".发生什么了？除了重新安装eclipse或创建新工作区之外的任何解决方案？

我正在使用Axis2 1.4.1和eclipse.

在Eclipse中,当您单击方法名称变量或对象时,相同的那些在代码中的其他位置以特定颜色突出显示,以便于查找.

Xcode中是否有类似的功能？

是否可以在Java中使用两个具有相同名称但不同参数和返回类型的方法？看起来它是一个很好的方法来推广一个简单的getter和setter ..你可以用构造函数来做到这一点,为什么不使用常规方法？例如

为什么不能做..

int getVal() {

return int;
}

boolean getVal() {

return true;

}

setVal(int a) {
}

和

setVal(boolean a) {

}
