我有这个结构:
接口IProjectService,由ProjectServiceImpl实现.
现在我有一个控制器,我想在其中使用依赖注入:
@Controller
@RequestMapping(value="/testFolder")
public class MyDIController {
...
private IProjectService projectServiceImpl;
public void setProjectServiceImpl(IProjectService projectServiceImpl) {
this.projectServiceImpl= projectServiceImpl;
}
...
@RequestMapping(value="/project", method=RequestMethod.GET)
public @ResponseBody Project getProject() {
Project project = this.projectServiceImpl.getProject(12); // line 37! (id 12 is a test case, it does exist, here is he error: this.projectServiceImpl = null)
return project;
}
}
在我的applicationContext.xml中,我有以下几行代码:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="projectServiceImpl" class="com.mydomain.project.service.impl.ProjectServiceImpl" />
<bean id="projectService" class="com.mydomain.project.service.IProjectService">
<property name="projectServiceImpl">
<ref local="projectServiceImpl"/>
</property>
</bean> …这是一个愚蠢的问题,因为我找不到合适的关键字来通过搜索谷歌来获得答案,不幸的是.

我需要在客户端和其他方面添加服务器端变量.因为我需要使用javascript从客户端设置一个值,并在页面后面的代码中访问相同的值.
我必须使用C#.Net和javascript.

如何声明std map常量ie,
int a[10] = { 1, 2, 3 ,4 };
std::map <int, int> MapType[5] = { };
int main()
{
}
在about片段中,可以给整数数组a赋值1,2,3,4 ,类似地如何声明一些常量MapType值而不是在main()函数中添加值.
我正在尝试使用Firefox的WebDriver,我想询问是否可以处理"下载"窗口(接受或拒绝传入的下载请求)？
例如,简单的代码:
import selenium.firefox.webdriver
dr = selenium.firefox.webdriver.WebDriver()
# Firefox is showed up.
# Let's say I'd want to download python.
dr.get('http://python.org/ftp/python/3.1.3/python-3.1.3.msi')
# Download window is showed up.
# How could I accept the download request?
# As I understand, the method below should return
# two handles but I get only main window's handle.
handles = dr.get_window_handles()
# Seems like WebDriver cannot "see" this popup.
我已经尝试了一点,但尚未找到解决方案.我真的很感激任何提示.
非常感谢, - V.

如果脚本标记位于HTML页面正文的上方或下方,那么网站的性能是否重要？
如果在这之间使用如下:
<body>
..blah..blah..
<script language="JavaScript" src="JS_File_100_KiloBytes">
function f1() {
.. some logic reqd. for manipulating contents in a webpage
}
</script>
... some text here too ...
</body>
或者这更好吗？:
<script language="JavaScript" src="JS_File_100_KiloBytes">
function f1() {
.. some logic reqd. for manipulating contents in a webpage
}
</script>
<body>
..blah..blah..
..call above functions on some events like onclick,onfocus,etc..
</body>
还是这一个？:
<body>
..blah..blah..
..call above functions on some events like onclick,onfocus,etc..
<script language="JavaScript" src="JS_File_100_KiloBytes">
function f1() {
.. some logic reqd. …
