我试图将使用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:我的计算机是运行OS X Yosemite 10.10.3，带有Oracle Java JDK 8 1.8.0_45，Gradle 2.4和Apache Tomcat 7.0.47的Mac。我使用IntelliJ IDEA 14.1.4作为开发平台。
我从遵循此guide开始，我得到了一个 jar ，该 jar 启动了一个可以按预期工作的嵌入式容器。然后，我关注了在另一个guide末尾链接的有关converting a Spring Boot JAR Application to a WAR的文档。我遵循了Section 59.4 "Packaging executable jar and war files"中的说明，然后遵循了Section 74.1 "Create a deployable war file"中的说明。根据该站点其他面临相同问题的其他成员的帖子(here，here，here和here，仅举几例)，我现在应该可以创建一个创建WAR并将其部署到我的 Tomcat 不幸的是，这种情况并非如此。
该项目包含以下3个Java文件:Application.java，Greeting.java和GreetingController.java。第一个如下:
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“gradle war”任务，则会生成一个大约8 Mb的WAR文件。我可以成功地将其部署到本地Tomcat，但是当我将浏览器指向http://localhost:8080/rest/hello?name=World时，我得到的是空白页面，而不是带有预期JSON的页面。如果运行任务“gradle build”或“gradle bootRepackage”，则将同时获得JAR和WAR及其原始版本。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，可能对他们有所帮助。原始版本的大小均约为8 Mb，而JAR和WAR的大小均为12 Mb。如果同时部署两个WAR，则不会收到任何错误消息，但在浏览器中也没有任何结果。这里有人建议说web.xml可能会丢失，实际上没有WAR实际包含这样的文件。我之所以这样说是因为我的Tomcat不是很新，并且出于某种原因，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
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，则没有任何改变。
到底是怎么回事？我想念什么？您能给我解释一下问题是什么，该怎么做才能在Tomcat上成功部署此玩具服务？提前谢谢了。
由于上述日志并没有真正帮助，因此我尝试重新启动Tomcat守护程序，并获得了更有意义的信息。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:giu 24, 2015 11:11:49 AM org.apache.catalina.core.AprLifecycleListener init

如果我尝试使用Web服务，则
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/2015:11:23:20 +0200] "GET /rest/hello?name=World HTTP/1.1" 404 5
由于我觉得这些日志并没有真正的帮助，因此我尝试关闭并启动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:giu 24, 2015 11:36:56 AM org.apache.catalina.startup.HostConfig deployWAR

通过查看这些日志，我感觉到Spring的自动魔术过程中出现了一些故障，但是不幸的是，我不知道该如何解决该问题。有什么帮助吗？
最佳答案
您正在使用什么版本的Java？ gradle文件指示您打算使用Java 8，但是此错误表明您不打算使用Java 8。
java.lang.NoSuchMethodError: java.lang.reflect.Parameter.isNamePresent()
The Parameter class was not introduced until java 8。您的tomcat使用哪个Java版本？
