【问题描述】：
我正在尝试将使用 Spring Boot 构建的 RESTful Web 服务部署到 Tomcat 实例中，但收效甚微。
我的软件配置如下：我的电脑是运行OS X Yosemite 10.10.3的Mac，有Oracle Java JDK 8 1.8.0_45、Gradle 2.4和Apache Tomcat 7.0.47。我使用IntelliJ IDEA 14.1.4作为开发平台。
我首先关注guide，然后我得到了一个 jar，它启动了一个按预期工作的嵌入式容器。然后我按照链接在另一个guide 末尾的关于converting a Spring Boot JAR Application to a WAR 的文档进行操作。我按照Section 59.4 "Packaging executable jar and war files" 中的说明进行操作，然后按照Section 74.1 "Create a deployable war file" 中的说明进行操作。根据该网站其他几个面临同样问题的成员的帖子（here、here、here 和here，仅举几例），我现在应该可以创建一个创建一个 WAR 并将其部署在我的 Tomcat 上。不幸的是，事实并非如此。
该项目包含以下 3 个 Java 文件：Application.java、Greeting.java 和 GreetingController.java。第一种如下：
package hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
第二个文件包含以下内容：
package hello;
public class Greeting {
private final long id;
private final String content;
public Greeting(long id, String content) {
this.id = id;
this.content = content;
}
public long getId() {
return id;
}
public String getContent() {
return content;
}
}
最后，后一个文件是：
package hello;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
@RequestMapping("/hello")
public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
return new Greeting(counter.incrementAndGet(), String.format(template, name));
}
}
该项目还包含以下 build.gradle 文件：
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.4.RELEASE")
}
}
apply plugin: 'war'
apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'spring-boot'
sourceCompatibility = 1.8
targetCompatibility = 1.8
war {
baseName = 'rest'
// version = '0.1.0'
}
repositories {
mavenLocal()
mavenCentral()
}
configurations {
providedRuntime
}
dependencies {
compile("org.springframework.boot:spring-boot-starter-web")
providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
testCompile("junit:junit")
}
现在，如果我运行任务“gradle war”，我会生成一个大约 8 Mb 的 WAR 文件。我可以成功地将它部署到我的本地 Tomcat，但是当我将浏览器指向 http://localhost:8080/rest/hello?name=World 时，我得到了一个空白页面，而不是带有预期 JSON 的页面。如果我运行任务“gradle build”或“gradle bootRepackage”，我会得到一个 JAR 和一个 WAR 以及它们的原始版本。我之所以提到这些命令，是因为我在任何地方都没有看到它们，知道它们可能很有用。原始版本的大小都在 8 Mb 左右，而 JAR 和 WAR 的大小均为 12 Mb。如果我同时部署两个 WAR，我不会收到任何错误消息，但浏览器中也没有任何结果。这里有人建议 web.xml 可能丢失，实际上没有 WAR 实际上包含这样的文件。我这么说是因为我的 Tomcat 不是很新，出于某种原因，我认为 Spring Boot 必须从上面的代码和注释中自动创建一个 web.xml。
正如@dunni 在 cmets 中所建议的，这里是我的 Tomcat 日志文件。首先catalina.log：
giu 24, 2015 10:35:01 AM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive /usr/local/apache-tomcat-7.0.47/webapps/rest.war
然后localhost.log:
giu 24, 2015 10:35:02 AM org.apache.catalina.core.ApplicationContext log
INFO: Spring WebApplicationInitializers detected on classpath: [org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration@4dfaba52]
最后是manager.log：
giu 24, 2015 10:34:43 AM org.apache.catalina.core.ApplicationContext log
INFO: HTMLManager: list: Listing contexts for virtual host 'localhost'
giu 24, 2015 10:34:44 AM org.apache.catalina.core.ApplicationContext log
INFO: HTMLManager: list: Listing contexts for virtual host 'localhost'
giu 24, 2015 10:35:02 AM org.apache.catalina.core.ApplicationContext log
INFO: HTMLManager: list: Listing contexts for virtual host 'localhost'
以上内容是我部署WAR后得到的。如果我随后尝试连接到 http://localhost:8080/、http://localhost:8080/rest/、http://localhost:8080/rest/hello 或 http://localhost:8080/rest/hello?name=World，则没有任何变化。
发生了什么事？我错过了什么？你能解释一下问题是什么，我该怎么做才能在 Tomcat 上成功部署这个玩具服务？非常感谢。
由于上述日志没有真正的帮助，我尝试重新启动 Tomcat 守护程序，我得到了一些更有意义的东西。现在我有以下文件：catalina.log、catalina.out、host-manager.log（空）、launchd.stderr（空）、launchd.stdout、localhost_access_log.txt（空）、localhost.log 和 manager.log（空） . catalina.log 和 catalina.out 现在包含以下内容：

如果我尝试使用 Web 服务，localhost_access_log.txt 会更新为：
217.20.22.194 - - [24/Jun/2015:11:23:16 +0200] "GET / HTTP/1.1" 200 11444
217.20.22.194 - - [24/Jun/2015:11:23:19 +0200] "GET /rest/ HTTP/1.1" 404 5
217.20.22.194 - - [24/Jun/2015:11:23:19 +0200] "GET /rest/hello HTTP/1.1" 404 5
217.20.22.194 - - [24/Jun/2015:11:23:20 +0200] "GET /rest/hello?name=World HTTP/1.1" 404 5
由于我感觉这些日志并没有真正的帮助，我尝试关闭和启动 Tomcat。在这种情况下，我在catalina.log 和catalina.out 中发现了一些有趣的东西。前者：

通过查看这些日志，我感觉 Spring 的自动魔法过程中出现了一些问题，但不幸的是我不知道是什么以及如何解决它。有什么帮助吗？

在 Servlet-3.0 兼容的应用程序中不需要 web.xml。 SpringBootServletInitializer 完成了这项工作。 tomcat 日志文件中是否还有任何日志消息？

@dunni 感谢您的回复，我认为我需要一个
web.xml（并且 Spring Boot 正在从项目中的 Java 代码和注释中生成一个），因为我的 Tomcat 不是很新。感谢您建议查看日志文件（顺便说一下，我将添加到我的问题中）：我不应该在深夜发布任何内容，否则我会错过这些琐碎的事情。跨度> -
我将我的 Tomcat 更新到最新的 8 版本（8.0.23），但仍然没有运气......
