如果确实想要加快应用程序上下文,请禁用<组件扫描,并在运行任何测试之前执行以下例程
Resource resource = new ClassPathResource(<PUT_XML_PATH_RIGHT_HERE>); // source.xml, for instance
InputStream in = resource.getInputStream();
Document document = new SAXReader().read(in);
Element root = document.getRootElement();
/**
* remove component-scanning
*/
for ( Iterator i = root.elementIterator(); i.hasNext(); ) {
Element element = (Element) i.next();
if(element.getNamespacePrefix().equals("context") && element.getName().equals("component-scan"))
root.remove(element);
}
in.close();
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(true);
for (String source: new String[] {"com.mycompany.framework", "com.mycompany.service"}) {
for (BeanDefinition bd: scanner.findCandidateComponents(source)) {
root
.addElement("bean")
.addAttribute("class", bd.getBeanClassName());
}
}
//add attribute default-lazy-init = true
root.addAttribute("default-lazy-init","true");
/**
* creates a new xml file which will be used for testing
*/
XMLWriter output = new XMLWriter(new FileWriter(<SET_UP_DESTINATION_RIGHT_HERE>));
output.write(document);
output.close();
除此之外,启用<context:annotation-config/>
由于您需要在运行任何测试之前执行上述例程,因此可以创建一个抽象类,您可以在其中运行以下内容
为测试环境设置 Java 系统属性,如下所示
-Doptimized-application-context=false
和
public abstract class Initializer {
@BeforeClass
public static void setUpOptimizedApplicationContextFile() {
if(System.getProperty("optimized-application-context").equals("false")) {
// do as shown above
// and
System.setProperty("optimized-application-context", "true");
}
}
}
现在,对于每个测试类,只需扩展初始值设定项
