如何用应用程序上下文配置文件替换web.xml?

BackgroundI'm trying to implement integration test for controller in Spring. I DON'T want to use WebApplicationInitializer (Java config for Spring) to run my web app. I want to use xml based configurations. However, @ContextConfiguration could not load web.xml, so I created application-context.xml. The problem is web.xml and application-context.xml are serving the same purpose,QuestionCan I remove web.xml in favor of application-context.xml? If I remove web.xml, the test would pass, but the web app won't run in Tomcat.CodesThis is my test class:@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {"file:path/to/application-context.xml"})@WebAppConfigurationpublic class HelloControllerIntegrationTest { @Autowired private WebApplicationContext context; private WebClient webClient; @Before public void setup() throws Exception { MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(context).build(); webClient = new WebClient(); webClient.setWebConnection(new MockMvcWebConnection(mockMvc)); } @Test public void testPrintWelcome() throws Exception { // I'm trying to print out the page for now UnexpectedPage welcomePage = webClient.getPage("http://localhost/"); InputStream is = welcomePage.getInputStream(); java.util.Scanner s = new java.util.Scanner(is).useDelimiter("\\A"); String a = s.hasNext() ? s.next() : ""; System.out.println(a); }}This is my application-context.xml<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"> <mvc:annotation-driven/> <mvc:default-servlet-handler/> <context:component-scan base-package="com.company.controller"/> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/pages/"/> <property name="suffix" value=".jsp"/> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> </bean></beans> 解决方案 What you need to understand is that web.xml and application-context.xml serve two completely different purposes.The first one is used to configure an application to run in a servlet container while the second one is used in order to provide Spring configuration. web.xml can of course be replaced by Java based configuration when the container supports servlet spec 3.0 or later.When running a Spring MVC test in order to test a Spring controller, web.xml is not used at all, since the test is not run in a servlet container because the test framework mocks out all the dependencies. You could easily have Spring MVC tests for code that pass, but not have a web.xml at all if you are in a TDD environment.In conclusion, the concerns addressed by web.xml and application-context.xml are orthogonal and one can be used without caring about the other.Also to clarify, the configuration supplied by web.xml or the WebApplicationInitializer alternative cannot be supplied in application-context.xml 这篇关于如何用应用程序上下文配置文件替换web.xml?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
