java - 将 WAR 部署到 Tomcat(Spring Boot + Angular)

Question

我正在尝试将带有 WAR 打包的 Spring Boot 应用程序部署到 Tomcat 10 .应用程序已成功部署，但是，当我尝试访问端点时，它会导致 404 Not Found。

WAR 文件:application.war

http://localhost:8080/application/api/abc -> 404 Not Found (Spring Boot Endpoint)
http://localhost:8080/application/abc -> 404 Not Found (Angular URL which calls /api/abc)

Tomcat webapps/application文件夹包含以下内容和 index.html ( Angular )有<base href="/">

---

讨论 here , 我添加了一个类 AppServletInitializer延伸SpringBootServletInitializer如下

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

在 pom.xml 中，我添加了对 spring-boot-starter-tomcat、tomcat-embed-jasper 的依赖并设置打包选项作为war。我已经分享了简化的(删除了依赖项，插件。如果需要，将添加相同的)

pom.xml

我们在客户端使用 Angular，资源位于静态文件夹中。

环境: Spring 启动 2.1.8， Angular 8,Java 11，

我已经提到过，不幸的是，他们都不适合我。任何帮助将不胜感激

1. Create a Deployable War File
2. Spring Boot War Deploy
3. Can not access deployed WAR file on Tomcat

Answer 1

项目中的配置是正确的。如评论中所述，Tomcat 10 可能存在一些问题，因为它处于 alpha 版本中。我用过 Tomcat 9，它运行良好。

配置如下。

第 1 步: 在 pom.xml

中将打包选项更改为 war

<packaging>war</packaging>

第 2 步: 扩展 SpringBootServletInitializer

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

/**
 * This is a helper Java class that provides an alternative to creating a {@code web.xml}.
 * This will be invoked only when the application is deployed to a Servlet container like Tomcat, JBoss etc.
 */
public class ApplicationWebXml extends SpringBootServletInitializer {

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

第 3 步: 创建 WAR 文件

mvn clean install 

我们开始吧!我们可以访问端点

http://localhost:8080/context-path/endpoint OR
http://localhost:8080/war-filename/endpoint

我们还可以为 war 创建配置文件如下
