我正在加载.war文件，并将其作为Web应用程序添加到嵌入式Tomcat服务器。

@Bean
public EmbeddedServletContainerFactory servletContainerFactory() {

    LOGGER.info("Adding web app");

    return new TomcatEmbeddedServletContainerFactory() {

        @Override
        protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) {

            String appHome = System.getProperty(Environment.APP_HOME);

            String targetFileName = "web-0.0.1-SNAPSHOT.war";
            InputStream resourceAsStream = getClass().getClassLoader().getResourceAsStream(targetFileName);

            LOGGER.info(System.getProperty("user.name"));
            LOGGER.debug("Loading WAR from " + appHome);

            File target = new File(Paths.get(appHome, targetFileName).toString());

            try {

                LOGGER.info(String.format("Copy %s to %s", targetFileName, target.getAbsoluteFile().toPath()));
                java.nio.file.Files.copy(resourceAsStream, target.getAbsoluteFile().toPath(), StandardCopyOption.REPLACE_EXISTING);

                Context context = tomcat.addWebapp("/", target.getAbsolutePath());
                context.setParentClassLoader(getClass().getClassLoader());

            } catch (ServletException ex) {
                throw new IllegalStateException("Failed to add webapp.", ex);
            } catch (Exception e) {
                throw new IllegalStateException("Unknown error while trying to load webapp.", e);
            }

            return super.getTomcatEmbeddedServletContainer(tomcat);
        }
    };
}

到目前为止，这是可行的，但是如果我访问http：// localhost：8080 /
web，我会得到

2017-03-04 11:18:59.588  WARN 29234 --- [nio-8080-exec-2] o.s.web.servlet.PageNotFound             : Request method 'GET' not supported

和回应

Allow: POST

我敢肯定，我所要做的就是允许该GET方法启用，/web并希望war可以通过Web浏览器访问从加载的文件提供的静态Web内容。

如何/在何处配置端点以允许GET请求？

我想介绍一个WebController在描述本教程。

@Controller
public class WebController {

   private final static Logger LOGGER = Logger.getLogger(WebController.class);

   @RequestMapping(value = "/web", method = RequestMethod.GET)
   public String index() {
       LOGGER.info("INDEX !");
       return "index";
   }
}

在日志输出中，我可以看到它已正确映射：

RequestMappingHandlerMapping : Mapped "{[/web],methods=[GET]}" onto public java.lang.String org.ema.server.spring.controller.dl4j.WebController.index()

但这并不能改变我无法访问该网站的事实。

我还配置了InternalResourceViewResolver：

@Configuration
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter {

    private final static Logger LOGGER = Logger.getLogger(MvcConfiguration.class);

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        LOGGER.info("configureViewResolvers()");
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();

        resolver.setSuffix(".html");
        registry.viewResolver(resolver);
    }


    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

}

web.xml

由于我使用纯Java配置所有内容，因此该文件定义不多：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">

    <display-name>Easy Model Access Server</display-name>

    <listener>
        <listener-class>org.ema.server.ServerEntryPoint</listener-class>
    </listener>

    <context-param>
        <param-name>log4j-config-location</param-name>
        <param-value>WEB-INF/classes/log4j.properties</param-value>
    </context-param>

    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/web/*.html</url-pattern>
    </servlet-mapping>

</web-app>

复制

如果要重现此代码，则可以从github签出整个代码。您需要执行的所有操作：

mkdir ~/.ema
git clone https://github.com/silentsnooc/easy-model-access
cd easy-model-access/ema-server
mvn clean install
java -jar server/target/server-*.jar

这将克隆，构建并运行服务器。

目前~/.ema需要目录目录。服务器启动时将在其中复制WAR。
