404 Not found Spring 启动与 Tomcat 的战争

Question

我有 Spring boot 应用程序。这适用于嵌入式服务器。我可以使用 Postman 来测试 API。

现在我想在 Tomcat 8 上部署它，我创建 root.war 文件并将maven install 其放入 Tomcat/webapps/ 我运行 tomcat 没有任何错误。但是当我使用与邮递员相同的网址时，它给我 404 未找到。

我用于两者（嵌入式和 tomcat）的 url 示例：localhost:8080/auth/registration

我尝试server.context-path在 application.properties 中设置但没有结果。

我相信问题出在项目的配置中。

这是我的 pom.xml

编辑

我还发现 spring boot 可以编译为 JAR，这是比 war 更好的方法。如果更好的话如何更改 pom.xml 以在 jar 中编译。

所以我尝试按照下面的建议创建 jar 。我运行这个并java -jar得到 org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatEmbeddedServletContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.HttpEncodingAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.http.encoding-org.springframework.boot.autoconfigure.web.HttpEncodingProperties': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/ValidationException

Answer 1

步骤1：

添加/更新以下依赖项pom.xml（范围为provided），以告诉 Spring Boot 不要使用其嵌入式 Tomcat。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

第2步：

<properties>
      <packaging>war</packaging>
</properties>

步骤3：

SpringBootApplication 类应如下所示：

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}
