Question

我有Spring启动应用程序。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，我用maven install创建root.war文件并把它放到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，它会让我找不到404。

我同时用于（嵌入式和tomcat）的网址示例：localhost:8080/auth/registration

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

我认为问题在于项目的配置。

这是我的pom.xml

EDITED

此外，我发现Spring boot可以编译为JAR，比战争更好。如果更好的是如何更改pom.xml以便在jar中进行编译。

所以我尝试按照下面的建议创建jar。我用java -jar运行它并得到了 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

add these in pom.xml

<modelVersion>4.0.0</modelVersion>
<groupId>com.muna.manas</groupId>
<artifactId>core-java</artifactId>
<version>0.1.0-SNAPSHOT</version>
<packaging>jar</packaging>

The most important aspect here is the type – to create an executable jar, double check the configuration uses a jar type.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <classpathPrefix>libs/</classpathPrefix>
                <mainClass>
                    org.baeldung.executable.ExecutableMavenJar
                </mainClass>
            </manifest>
        </archive>
    </configuration>
</plugin>

Answer 2

步骤1：

将以下依赖项添加/更新到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>

步骤2：

<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);
    }

}
