使用 .war 将 SpringBoot 应用程序部署到 ec2，出现 404 错误

问题描述 投票：0回答：1

我有一个带有角度前端和 MySQL 数据库的 Spring Boot 应用程序。我正在尝试将它部署到 ec2，但我不明白为什么我会收到 404。

这是我的build.gradle：

plugins {
    id 'java'
    id 'war'
    id 'org.springframework.boot' version '2.7.8'
    id 'io.spring.dependency-management' version '1.0.15.RELEASE'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'


apply plugin: 'war'
war {
  enabled = true
  archiveFileName = "${archivesBaseName}.war"
  destinationDirectory = file("../")          // Project workspace directory
}

repositories {
    mavenCentral()
}

dependencies {
    implementation project(':MealPlan')

    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-security'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    runtimeOnly 'com.mysql:mysql-connector-j'
    
    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
    implementation 'org.springframework.boot:spring-boot-starter-tomcat'
    
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'org.springframework.security:spring-security-test'
}

tasks.named('test') {
    useJUnitPlatform()
}

这是我的应用程序.properties：

#### PORT CONFIG ####
server.port=8092

#### MYSQL DATASOURCE ####
spring.datasource.url=jdbc:mysql://localhost:3306/mealprepdb?useSSL=false&&useLegacyDatetimeCode=false&serverTimezone=US/Mountain
spring.datasource.username=mealprep
spring.datasource.password=mealprep
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

spring.jmx.default-domain=MealPlanner

这是我的 app.java:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@SpringBootApplication
public class MealPlannerApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(MealPlannerApplication.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(MealPlannerApplication.class, args);
    }
    
    @Bean
    public PasswordEncoder configurePasswordEncoder() {
       return new BCryptPasswordEncoder();
    }

}

感谢任何帮助，如果您需要查看其他内容，请告诉我。

到目前为止，我已经尝试更改生成的 war 文件名和 application.properties 中的默认域，并且我已经尝试在 build.gradle 中使用和不使用这两行进行部署

providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
implementation 'org.springframework.boot:spring-boot-starter-tomcat'

还有一些我想不起来的事情。两天来我一直在努力解决这个问题。

刚找到ec2实例上的tomcat日志

06-Mar-2023 18:10:33.353 INFO [localhost-startStop-32] org.apache.catalina.core.ApplicationContext.log Initializing Spring embedded WebApplicationContext

我还有 3 个其他应用程序在运行，所以这并不奇怪，但它似乎无法识别最新的应用程序。

我在 catalina.log 中找到了相关的堆栈跟踪

与其手动将 Spring BOOT 应用程序放置到 EC2 实例上，不如使用 AWS Elastic Beanstalk。这使您可以以简化的方式上传和部署 Web 应用程序。

您可以使用 Maven 将您的 Spring BOOT 项目打包成一个 JAR。生成 JAR 后，您就可以上传到 Elastic Beanstalk，无论如何都会将应用程序放置在 EC2 实例上。

将应用程序部署到 AWS Elastic Beanstalk 后，您需要设置一些配置值，例如服务器端口等。我已经成功部署了使用 org.springframework.security.* 包的 Spring Boot 应用程序。

要查看使用 AWS SDK for Java V2 的简单 Thymeleaf UI 和 Java 类部署 Spring BOOT 应用程序的示例，请参阅此示例。

创建您的第一个 AWS Java Web 应用程序

注意最后有关于如何将 JAR 部署到 Elastic Beanstalk 的说明。
