网状物将Spring Boot RESTful Web服务部署到Tomcat时仍然缺少xml

王曜文
2023-03-14

我试图将一个用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：我的电脑是一台运行OS X Yosemite 10.10.3的Mac，带有OracleJavaJDK 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。

我从遵循这个指南开始，我得到了一个罐子，它启动了一个嵌入式容器，并按预期工作。然后，我遵循了另一个指南末尾链接的关于将Spring Boot JAR应用程序转换为WAR的文档。我遵循了第59.4节“打包可执行的jar和war文件”中的说明，然后是第74.1节“创建可部署的war文件”中的说明。根据这个网站上其他几个面临同样问题的成员的帖子（这里，这里，这里和这里，仅举几个例子），我现在应该能够创建一个创建战争并将其部署在我的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，问候语。java和问候控制器。java。第一个是：

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));
    }
}

该项目还包含以下生成。渐变文件：

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”，我将生成一个大约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我得到了一个空白页面，而不是页面与预期的JSON。如果我运行任务“gradle build”或“gradle bootRepackage”，我会得到一个JAR和一个WAR及其原始版本。我提到这些命令是因为我在任何地方都没见过它们，知道它们可能会很有用。原始版本的大小都在8 Mb左右，而JAR和WAR的大小为12 Mb。如果我部署了两个WAR，我不会收到错误消息，但是在浏览器中也不会有结果。这里有人暗示web.xml可能丢失了，事实上没有战争真正包含这样的文件。我这么说是因为我的Tomcat不是最近的，出于某种原因，我认为Spring Boot必须自动从上面的代码和注释中创建一个web.xml。

正如@dunni在评论中所建议的，这里是我的Tomcat日志文件。首先，catalina。日志：

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。日志：

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。日志：

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'

以上内容就是我在部署WAR之后得到的。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.

到底是怎么回事？我错过了什么？你能给我解释一下问题出在哪里，我该怎么做才能在Tomcat上成功部署这个玩具服务吗？非常感谢提前。

由于上面的日志没有真正的帮助，我尝试重新启动Tomcat守护进程，得到了一些更有意义的东西。现在我有以下文件：catalina。日志，卡塔琳娜。退出主机管理器。日志（空），启动。stderr（空），启动。stdout，本地主机访问日志。txt（空），localhost。日志和管理器。日志（空）<代码>卡塔琳娜。日志和catalina。out现在包含以下内容：

launchd.stdout包含：

并且localhost. log包含：

giu 24, 2015 11:11:52 AM org.apache.catalina.core.ApplicationContext log
INFO: Spring WebApplicationInitializers detected on classpath: [org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration@2d5eb959]

如果我尝试使用Web服务，localhost_access_log.txt将更新为：

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/2015:11:23:20 +0200] "GET /rest/hello?name=World HTTP/1.1" 404 5

因为我觉得这些日志并没有真正的帮助，所以我尝试关闭并启动Tomcat。在本例中，我在catalina中发现了一些有趣的东西。日志和catalina。输出。前者：
