如何在Tomcat 7中制作可部署的Spring Boot 1.2.3 WAR文件

Question

构建可部署的war包的Spring Boot应用程序所需的配置是什么，可以在运行在Java 8上的Tomcat 7中部署。

经过数小时的调试，我能够得到war文件，但是一旦部署到Tomcat上，它并没有被正确地部署，并且API无法访问，返回404错误。

catalina日志文件如下：

INFO: Deploying web application archive /var/lib/tomcat7/webapps/test.war
May 13, 2015 1:10:57 PM org.apache.catalina.startup.HostConfig deployDirectory
INFO: Deploying web application directory /var/lib/tomcat7/webapps/ROOT

你看到了吗？http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file - makasprzak

是的，我尝试了提到的步骤，但仍然得到相同的日志。没有收到错误消息，但其余调用不可访问。 - Nilesh Bhosale

.sources(this.application) 对我来说看起来有问题。应该是 .sources(Application.class)。 - Andy Wilkinson

Answer 1

移除静态字段application并将configure方法的返回值更改如下：

return application
            .showBanner(true)
            .parent(Global.class)
            .sources(Application.class)
            .profiles("container")
            ;

若要创建可部署的Tomcat 7 war文件，请阅读此指南：

1. <packaging>war</packaging>

2. 覆盖：SpringBootServletInitializer.configure

   @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);
       }
   }
   

3. 修改 pom.xml

   <properties>
       <tomcat.version>7.0.78</tomcat.version>
       <servlet-api.version>3.0.1</servlet-api.version>
   </properties>
   
   <dependencies>
       <dependency>
           <groupId>javax.servlet</groupId>
           <artifactId>javax.servlet-api</artifactId>
           <version>${servlet-api.version}</version>
           <scope>provided</scope>  <!-- provided: tomcat/lib/servlet-api.jar -->
       </dependency>
       <dependency>
           <groupId>org.apache.tomcat</groupId>
           <artifactId>tomcat-juli</artifactId>
           <version>${tomcat.version}</version>
           <scope>runtime</scope> <!-- runtime: tomcat/bin/tomcat-juli.jar -->
       </dependency>
       <!-- 删除以下依赖:
        <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-tomcat</artifactId>
           <scope>provided</scope>
       </dependency>
       -->
   </dependencies>

@SpringBootApplication public class ApiApplication extends SpringBootServletInitializer {

@SpringBootApplication public class ApiApplication继承SpringBootServletInitializer {

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

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

}
