在JUnit中加载Spring配置文件的方式

@BeforeClass
 public static void loadContext() {
  
  //加载单个spring文件
  ApplicationContext context00 = new ClassPathXmlApplicationContext("spring-global-db.xml");
  
  //加载类路径下的配置文件ClassPathXmlApplicationContex
  ApplicationContext context0 = new ClassPathXmlApplicationContext(
    new String[]{"spring-global-db.xml",
        "spring-dao.xml",
        "spring-service.xml"});

  //加载文件系统下的路径中的配置文件
  String basePath = System.getProperty("user.dir");
  String db = basePath+"/WebRoot/WEB-INF/spring/spring-global-db.xml";
  String dao = basePath+"\\WebRoot\\WEB-INF\\spring\\spring-dao.xml";
  String service = basePath+"\\WebRoot\\WEB-INF\\spring\\spring-service.xml";
  ApplicationContext context1 =
   new FileSystemXmlApplicationContext(new String[]{db, dao, service});
  
  //用WEB应用的路径加载spring配置文件
  XmlWebApplicationContext context2 = new XmlWebApplicationContext();
  context2.setConfigLocations(new String[]{
   "/WEB-INF/spring/spring-global-db.xml",
   "/WEB-INF/spring/spring-dao.xml",
   "/WEB-INF/spring/spring-service.xml"
  });
  //需要servletContext变量，一般由request.getSession().getSersvletContext()获取
  context2.setServletContext(request.getSession().getServletContext());
  context2.refresh();
  
  manageEmpServiceImpl = (ManageEmpServiceImpl) context1.getBean("manageEmpServiceImpl");
  
 }
