我正在为我的Spring控制器运行集成测试。测试包括一个配置文件(view-configuration.xml),tilesConfigurer其中包含我收到错误的bean No URL for ServletContext resource。以下是错误跟踪,配置,测试和项目结构:

鉴于-configuration.xml文件:

<mvc:resources location="/resource/" mapping="/static/**"></mvc:resources>

<bean id="tilesViewResolver"
    class="org.springframework.web.servlet.view.tiles3.TilesViewResolver">
</bean>
<bean id="tilesConfigurer"
    class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
    <property name="definitions">
        <list>
            <value>/WEB-INF/layout/default.xml</value>
        </list>
    </property>
</bean>

测试

@RunWith(value=SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = { "file:WebContent/WEB-INF/dispatcher-servlet.xml",
    "classpath:com/zerosolutions/configuration/service-configuration.xml",
    "classpath:com/zerosolutions/configuration/security-configuration.xml",
    "classpath:com/zerosolutions/test/datasource_test.xml",
    "classpath:com/zerosolutions/configuration/view-configuration.xml"})
public class TestingFrontController {

@Autowired
private WebApplicationContext wac;

private MockMvc mockMvc;

@Before
public void setUp(){
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}

@Test
public void getLoginSignupPage() throws Exception{
    mockMvc.perform(get("/login"))
    .andExpect(status().isOk())
    .andExpect(forwardedUrl("login"));
}

}

项目结构:

为什么它无法找到资源?

用户回答回答于

当Spring TestContext Framework加载一个ApplicationContext带有注释的测试时@WebAppConfiguration,它实际上加载了一个WebApplicationContext需要a的测试ServletContext。在集成测试中,Spring MockServletContext为您创建了一个resourceBasePathset,其中value包含@WebAppConfiguration注释中属性的值。

如果您已经阅读了Javadoc @WebAppConfiguration,您会注意到默认路径是src/main/webapp

因此,答案是您不遵循WAR项目的Maven约定。换句话说,src/main/webapp它不是您的Web内容的根。相反,在你的项目中WebContent

更改以下声明@WebAppConfiguration应解决您的问题。

@WebAppConfiguration("WebContent")

我尝试了Sam提供的解决方案。它对我不起作用。

所以我尝试将tiles.xml放到资源文件夹中,因为我知道它只需要能够在上下文中找到它。

我知道这不是解决问题的正确方法。但它对我有用。

@Bean
public TilesConfigurer tilesConfigurer() {
    final TilesConfigurer configurer = new TilesConfigurer();
    configurer.setDefinitions("classpath:tiles.xml");
    configurer.setCheckRefresh(true);
    return configurer;
}
