使用嵌入式 tomcat 实例时，有没有办法指定不同于web.xml标准的方法？WEB-INF/web.xml
我想web.xml在我的src/test/resources（或其他一些区域）中放置一个并web.xml在启动嵌入式 tomcat 时参考它。
这是我现有的启动tomcat实例的代码
tomcat = new Tomcat();
String baseDir = ".";
tomcat.setPort(8080);
tomcat.setBaseDir(baseDir);
tomcat.getHost().setAppBase(baseDir);
tomcat.getHost().setAutoDeploy(true);
tomcat.enableNaming();
Context ctx = tomcat.addWebApp(tomcat.getHost(), "/sandbox-web", "src\\main\\webapp");
File configFile = new File("src\\main\\webapp\\META-INF\\context.xml");
ctx.setConfigFile(configFile.toURI().toURL());
tomcat.start();
我从一个 tomcat 实例启动这个服务器，我想在运行单元测试时执行以下操作
- 关闭
contextConfigLocation - 指定一个自定义
ContextLoaderListener来设置嵌入式 tomcat 的父ApplicationContext级。
这个文件可以这样指定：
File webXmlFile = new File("src\\test\\resources\\embedded-web.xml");
编辑
在经历了很多挫折之后，我意识到无论我做什么，我都无法说服 tomcatWEB-INF寻找web.xml. 看来我必须完全忽略并以编程方式web.xml设置项目。web.xml
我最终得到了这个配置：
cucumber.xml 用于配置测试

步骤定义
public class StepDefs {

protected EmployeeEntityService employeeEntityService;
@Given("^the following divisions exist$")
public void the_following_divisions_exist(DataTable arg1) throws Throwable {

employeeEntityService.persistEmployee(employee);
}

public void there_are_no_existing_surveys() throws Throwable {
}
@When("^I register a new survey with the following information$")
public void I_register_a_new_survey_with_the_following_information(DataTable arg1) throws Throwable {
Capabilities capabilities = DesiredCapabilities.htmlUnit();
final HtmlUnitDriver driver = new HtmlUnitDriver(capabilities);
driver.get("http://localhost:8080/sandbox-web/myFirst");
}
@Then("^the surveys are created$")
public void the_surveys_are_created() throws Throwable {
// Express the Regexp above with the code you wish you had
throw new PendingException();
}
@Then("^a confirmation message is displayed saying: \"([^\"]*)\"$")
public void a_confirmation_message_is_displayed_saying(String arg1) throws Throwable {
// Express the Regexp above with the code you wish you had
throw new PendingException();
}
}
动作类
@Results({ @Result(name = "success", location = "myFirst.page", type = "tiles") })
@ParentPackage("default")
@Breadcrumb(labelKey = "ca.statcan.icos.sandbox.firstAction")
@SuppressWarnings("serial")
public class MyFirstAction extends HappyfActionSupport {
private List<Employee> employees;
@Autowired
private EmployeeEntityService employeeEntityService;
@Override
public String execute() {
employees = employeeEntityService.getAllEmployee();
if (employees.size() == 0) {
// persist data in memory
final Employee employee1 = new Employee(1, "First", "John", null, "613-222-2222");
employeeEntityService.persistEmployee(employee1);
final Employee employee2 = new Employee(2, "Second", "John", null, "613-222-2223");
employeeEntityService.persistEmployee(employee2);
employees = employeeEntityService.getAllEmployee();
}
return SUCCESS;
}
public List<Employee> getEmployees() {
return employees;
}
}
有了这个，嵌入式 tomcat 可以正确启动，并且在我尝试导航到网页之前一切似乎都很顺利。在StepDefs课堂上，EmployeeEntityService正确注入了。但是，在Action类中，EmployeeEntityservice没有注入（它仍然存在null）。
据我所知，我正在ApplicationContext正确设置嵌入式 Tomcat 的父级。那么为什么服务器不使用父上下文来获取EmployeeEntityService呢？
