在tomcat中部署后无法访问Spring Boot应用程序

我已经使用Spring Boot" title="Spring Boot">Spring Boot创建了一个RESTAPI。我正在使用gradle作为构建工具。我已经使用嵌入式容器测试了该应用程序，并且运行良好。我可以通过访问我的应用程序localhost:8080/foo/bar。

现在，我已将其部署到tomcat，没有任何错误。

Mar 17, 2016 1:58:47 PM org.apache.catalina.startup.HostConfig deployWAR
INFO: Deploying web application archive /usr/local/apache-tomcat-7.0.65/webapps/foo.war

INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

但是我现在无法通过访问该应用程序localhost:8080/foo/bar。我可以看到tomcat正在运行localhost:8080

这是build.gradle文件。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.3.RELEASE")
    }
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'
apply plugin: 'war'
war {
    baseName = 'foo'
}
repositories {
    mavenCentral()
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
configurations{
    providedRuntime
}
dependencies {
   compile 'org.springframework.boot:spring-boot-starter-web'
    providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
     compile 'com.google.code.gson:gson:2.6.2'
     compile 'org.springframework:spring-webmvc:4.2.5.RELEASE'
     compile 'org.json:json:20151123'
     providedRuntime 'javax.ws.rs:javax.ws.rs-api:2.0.1'
     providedRuntime 'javax.servlet:javax.servlet-api:3.1.0'
     providedRuntime 'javax.servlet:jstl:1.2'
     testCompile("junit:junit")
}
task wrapper(type: Wrapper) {
    gradleVersion = '2.11'
}

我有一个application.properties包含以下代码的文件

server.context-path=/foo

并且我在控制器中的请求映射设置为

    @CrossOrigin
    @RequestMapping("/bar")
    public String bar(){
       // Code
    }
@SpringBootApplication
public class FooApplication {
    public static void main(String[] args) {
        SpringApplication.run(FooApplication.class, args);
    }
    // Used when deploying to a standalone servlet container
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(FooApplication.class);
    }
}

回答：

要部署SpringBoot应用程序，您必须具有一个扩展org.springframework.boot.context.web.SpringBootServletInitializer和覆盖的配置类。org.springframework.boot.context.web.SpringBootServletInitializer.configure(SpringApplicationBuilder

application)

因此，当将应用程序部署在JEE Servlet容器中时，Spring Boot应用程序将被正确部署并提供服务。

@Configuration
public class AppServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
}

的Application.class是相同的类中SpringApplication.run(Application.class,

args);的主方法
