Java 将WAR部署到Tomcat（弹簧靴+；角度）

我正在尝试将带有WAR打包的Spring Boot应用程序部署到Tomcat 10。但是，当我尝试访问端点时，应用程序成功部署，结果是404找不到

WAR文件：application.WAR

Tomcat

webapps/application

文件夹由以下内容和

index.html

（角度）have

---

如前所述，我添加了一个类

AppServletInitializer

，它扩展了

SpringBootServletInitializer

，如下所示

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

在pom.xml中，我为spring boot starter tomcat、tomcat embed jasper添加了依赖项，并将打包选项设置为war。我已经分享了简化版（删除了依赖项、插件。如果需要，将添加相同的内容）

pom.xml

我们在客户端使用Angular，资源位于静态文件夹中。

环境： 弹簧靴2.1.8， 角度8， 爪哇11

我已经提到了，不幸的是，没有一个是为我工作的。任何帮助都将不胜感激

项目中的配置是正确的。正如评论中提到的，Tomcat10在alpha版本中可能存在一些问题。我使用了Tomcat 9，它工作得很好

配置如下所示

步骤1:在pom.xml中将packing选项更改为war

war

第2步：扩展SpringBootServletInitializer

步骤3:创建WAR文件

我们走了！我们可以在以下位置访问端点：

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，如下所示

3.2.3
org.springframework.boot
springbootmaven插件
org.apache.maven.plugins
maven战争插件
${maven war plugin.version}
战争
包裹
WEB-INF/**，META-INF/**
假的
目标/类/静态/
src/main/webapp
WEB-INF/**
战争
org.apache.maven.plugins
maven战争插件

这不是一个真正的答案，只是一个简单的想法：打开start.spring.io并创建一个“示例项目”，该项目使用打包WAR以及java和spring启动版本生成一个工件。编译它并尝试在tomcat上部署，确保它按预期工作（这样您就可以确保tomcat正常），然后尝试比较创建的工件并查看差异。打开environment.ts文件，检查后端项目的基本URL。您是否在主类中使用

@SpringBootApplication

注释？您的主类应该扩展

SpringBootServletilizer

，并实现一个main来实际启动SpringApplication…您可以试试Mark所说的。另外，检查它是否在另一个版本的Tomcat中工作。9或8。10是最新版本，它仍处于alpha阶段。请确保您的

服务器.contextPath

配置正确，请参阅此

server:
  servlet:
    context-path: /application

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);
    }
}

mvn clean install 

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