将WAR部署到Tomcat(Spring Boot + Angular) [英] Deploy WAR to Tomcat (Spring Boot + Angular)
本文介绍了将WAR部署到Tomcat(Spring Boot + Angular)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将带有 WAR 打包的Spring Boot应用程序部署到 Tomcat 10 .该应用程序已成功部署，但是，当我尝试访问端点时，结果为 404未找到.
WAR文件: application.war
http://localhost:8080/application/api/abc->找不到404(Spring引导端点)http://localhost:8080/application/abc->找不到404(调用/api/abc的角度URL) Tomcat webapps/application 文件夹包含以下内容，而 index.html (角度)具有< base href ="/">
如
环境:Spring Boot 2.1.8，角度8Java 11，
不幸的是，我已经提到他们都没有为我工作.任何帮助将不胜感激
解决方案
项目中的配置正确.如评论中所述，Tomcat 10可能与alpha版本一样存在问题.我已经使用了Tomcat 9，它运行正常.
配置如下.
步骤1: 将 pom.xml
中的打包选项更改为 war < packaging> war</packaging>
步骤2: 扩展了 SpringBootServletInitializer
import org.springframework.boot.builder.SpringApplicationBuilder;导入org.springframework.boot.web.servlet.support.SpringBootServletInitializer;/***这是一个辅助Java类，提供了创建{@code web.xml}的替代方法.*仅在将应用程序部署到Tomcat，JBoss等Servlet容器时才调用此方法.*/公共类ApplicationWebXml扩展了SpringBootServletInitializer {@Override受保护的SpringApplicationBuilder configure(SpringApplicationBuilder应用程序){返回application.sources(ApplicationApp.class);}} 第3步: 创建 WAR 文件
mvn全新安装 然后我们去！我们可以通过以下地址访问端点:
http://localhost:8080/context-path/endpoint或http://localhost:8080/war-filename/endpoint 我们还可以如下创建 war 的配置文件
< properties>< maven-war-plugin.version> 3.2.3</maven-war-plugin.version></properties>< build>< plugins>< plugin>< groupId> org.springframework.boot</groupId>< artifactId> spring-boot-maven-plugin</artifactId></plugin></plugins>< pluginManagement>< plugins>< plugin>< groupId> org.apache.maven.plugins</groupId>< artifactId> maven-war-plugin</artifactId>< version> $ {maven-war-plugin.version}</version><执行><执行><目标>< goal> war</goal></goals>< phase>包装</phase></execution></executions><配置>< warSourceIncludes> WEB-INF/**，META-INF/**</warSourceIncludes>< failOnMissingWebXml> false</failOnMissingWebXml>< warSourceDirectory> target/classes/static/</warSourceDirectory>< webResources><资源>< directory> src/main/webapp</directory>< includes>< include> WEB-INF/**</include></includes></resource></webResources></configuration></plugin></plugins></pluginManagement></build><个人资料><个人资料>< id> war</id>< build>< plugins>< plugin>< groupId> org.apache.maven.plugins</groupId>< artifactId> maven-war-plugin</artifactId></plugin></plugins></build></profile></profiles> I am trying to deploy the Spring Boot Application with WAR packaging to Tomcat 10. The application gets deployed successfully, however, when I try to access the endpoints it results in 404 Not Found.
WAR File: 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 folder consists of following and index.html (Angular) have <base href="/">
As discussed here, I have added a class AppServletInitializer which extends SpringBootServletInitializer as follow
@Configuration
public class AppServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(AutomationwhizApp.class);
}
}
In pom.xml, I have added the dependency for spring-boot-starter-tomcat, tomcat-embed-jasper and set packaging option as war. I have shared the simplified (removed dependency, plugins. will add the same if required)

We are using Angular on the client-side and resources are located in the static folder.
Environment: Spring Boot 2.1.8, Angular 8, Java 11,
I have already referred, unfortunately, none of them is working for me. Any help would be Appreciated
解决方案
The configuration was correct in the Project. As mentioned in the comment, there might be some issue with Tomcat 10 as it was in the alpha version. I have used Tomcat 9 it was working fine.
The configuration are as below.
Step 1: Change the packing option to war in pom.xml
<packaging>war</packaging>
Step 2: extends 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);
}
}
Step 3: Create WAR file
mvn clean install
And there we go! We can access the endpoints at
http://localhost:8080/context-path/endpoint OR
http://localhost:8080/war-filename/endpoint
We can also create the profile for war as below
<properties>
<maven-war-plugin.version>3.2.3</maven-war-plugin.version>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
