Spring Boot Web应用程序无法在Tomcat上运行-404错误

Question

注意：有与此类似的问题，但没有一种解决方案适合我。 我花了几天时间尝试使它生效。

我已将WAR文件部署到Tomcat，“ Tomcat Web应用程序管理器”显示该文件已启动。 单击Web应用程序“ / forecaster”时，出现404错误。 从调试器（IntelliJ）运行时，该Web应用程序可以工作。 该WAR文件名为“ forecaster.war”，我尝试过的路径为： http：// localhost：8080 / forecaster / http：// localhost：8080 / forecaster / forecast / http：// localhost：8080 / forecaster /预测/ 1

“ Catalina.sh启动”输出：

Using CATALINA_BASE:   /Library/Tomecat 
Using CATALINA_HOME:   /Library/Tomecat 
Using CATALINA_TMPDIR: /Library/Tomecat/temp 
Using JRE_HOME:        /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home 
Using CLASSPATH:       /Library/Tomecat/bin/bootstrap.jar:/Library/Tomecat/bin/tomcat-juli.jar 
Tomcat started.

的build.gradle：

buildscript {
    ext {
        springBootVersion = '1.4.3.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath("org.springframework.boot:spring-boot-devtools:1.4.3.RELEASE")
        classpath("org.springframework:spring-jdbc:4.3.5.RELEASE")
    }
}

apply plugin: 'war'

jar {
    baseName = 'forecaster'
    version = '0.0.3-SNAPSHOT'

    testCompile('org.springframework.boot:spring-boot-starter-test')

ForecasterApplication.java：

@SpringBootApplication(exclude=DataSourceAutoConfiguration.class)
public class ForecasterApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(ForecasterApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(ForecasterApplication.class, args);
    }
}

ForecastController.java：

package com.brian.project.forecaster.controller;

@Controller
public class ForecastController {

   @Autowired
   private DatabaseRepository databaseRepository;

   @RequestMapping(value = "forecast/{id}")
   public String getForecastForChain(@PathVariable Integer id, Model model) throws JsonProcessingException, IOException
   {

      model.addAttribute("futureForecastData", "Say 404 again I dare you...");
      model.addAttribute("storeName", "test store name");

      return "forecast";
   }
}

我最终按照这里的说明进行操作，而不是使用IntelliJ。

https://spring.io/guides/gs/spring-boot/#_run_the_application

要在本地运行该应用程序：

./gradlew build && java -jar build/libs/forecaster/forecaster-0.0.3-SNAPSHOT.jar

为了进行战争，我将其添加到build.gradle文件中：

war {
    baseName = 'forecaster'
    version = '0.0.3-SNAPSHOT'
}

然后我跑了：

./gradlew build

这在此处生成了WAR文件：

建立/库/预报/预报-0.0.3-SNAPSHOT.jar

然后将其复制到外部Tomcat8服务器（其中/ external-test /是已安装到/ Library / Tomcat / webapps的已安装samba文件夹）：

cp build/libs/forecaster/forecaster-0.0.3-SNAPSHOT.war /external-test/forecaster.war

现在，它可以使用以下URL：

HTTP：//本地主机：8080 /预测器/预测/ 1
