spring-boot - 将spring boot项目打包部署成war success with profile，但是访问页面时无法访问页面

Question

在我从 gradle 构建成功获取 war 文件后，我部署到 tomcat 容器，这也成功了。但是当我尝试访问 localhost:9999/fdr/test 时，它告诉我 This site can't be reached

我使用的 Tomcat 版本是 apache-tomcat-9.0.22。我已经更改了 build.gradle 文件以在 dependencies 部分下添加 providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'。另外为了让 Tomcat 知道我使用的配置文件，我在 application.properties 中添加了 spring.profiles.active=@activeProfiles@ 并且还有 application-dev .properties 在 src\main\resource 文件夹中。我生成war文件的方式是./gradlew -PactiveProfiles=dev clean build，生成war文件后，我把它放在Tomcat下的webapps文件夹中，然后启动它

对于build.gradle

plugins {
    id 'org.springframework.boot' version '2.1.6.RELEASE'
    id 'java'
    id 'war'
}

apply plugin: 'io.spring.dependency-management'

group = 'com.vincent.wartest'
version = '0.0.1'
sourceCompatibility = '1.8'

configurations {
    developmentOnly
    runtimeClasspath {
        extendsFrom developmentOnly
    }
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

processResources {
    filter org.apache.tools.ant.filters.ReplaceTokens, tokens: [
            activeProfiles: activeProfiles
    ]
}



dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-jdbc'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compileOnly 'org.projectlombok:lombok'
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
    annotationProcessor 'org.projectlombok:lombok'
    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    implementation('mysql:mysql-connector-java:8.0.13')

}

结构如下:

                    └───phoenix
                            PhoenixApplicationTests.java

由于代码是由 Intellij 自动生成的，它创建了一个名为 ServletInitializer.java 的类，其内容如下

package com.vincent.wartest.phoenix;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(PhoenixApplication.class);
    }

}

在com.vincent.wartest.controller中，它有简单的 Controller 类

import lombok.extern.slf4j.Slf4j;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/fdr")
@Slf4j
public class PhoenixController {

    @GetMapping(value="/test")
    public ResponseEntity<String> test(){
        LOGGER.info("Logger test");
        return new ResponseEntity<>("First test", HttpStatus.OK);
    }
}

预期结果:在tomcat上部署后，访问http://localhost:9999/fdr/test时，页面应该显示First test，并响应代码是 200 OK(通过在 Chrome 上检查 F12)

实际结果:当我访问该页面时，我得到 This site can't be reached via Tomcat is running properly

更新:这是 catalina.out

它实际上加载了我的开发配置文件，我配置了 server.port=9999，所以我预计它会在端口 9999 上启动我的页面。

来自您的日志:

Deployment of web application archive [C:\Users\zhibo\Desktop\apache-tomcat-9.0.22\webapps\phoenix-0.0.1.war] has finished in [4,388] ms

在 tomcat 上，应用程序根上下文以 war 名称命名，在本例中为:phoenix-0.0.1。所以你的申请将在

http://localhost:9999/phoenix-0.0.1/fdr/test

如果您想将版本保留在上下文路径中，最好将 war 命名为 phoenix##0.0.1.war。所以你的申请将在

http://localhost:9999/phoenix/0.0.1/fdr/test
