我正在嘗試使用 Spring Boot 設置一個簡單的 Web CRUD 應用程序。我知道我應該是 spring boot servelet 初始值設定項，但是在日志中，我懷疑它沒有正常運行，因為它沒有記錄我寫的內容。最終目標是讓我能夠訪問http://localhost:8080/LNU-Project/和 home.jsp 顯示。這是 github 上的鏈接。https://github.com/rjpruitt16/LNU-Project/tree/master/src/mainWebAppInitializer.javapackage com.project.LNUProject; import com.project.LNUProject.config.WebConfig; import lombok.extern.slf4j.Slf4j; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; import org.springframework.web.context.support.AnnotationConfigWebApplicationContext; import org.springframework.web.servlet.DispatcherServlet; import javax.servlet.ServletContext; import javax.servlet.ServletException; import javax.servlet.ServletRegistration; @Slf4j @SpringBootApplication public class WebAppInitializer extends SpringBootServletInitializer { private static final String DISPATCHER_SERVLET_NAME = "dispatcher"; public static void main(String[] args) { SpringApplication.run(WebAppInitializer.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(WebAppInitializer.class); } @Override public void onStartup(ServletContext servletContext) throws ServletException { log.info("onStartUp"); // create the spring application context AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext(); context.register(WebConfig.class); // create the dispatcher servlet DispatcherServlet dispatcherServlet = } }

請按照以下步驟在外部 tomcat 上部署 Spring Boot 應用程序：
需要打包一個 WAR 應用程序而不是一個 JAR。為此，我們將 pom.xml 更改為以下內容：
<packaging>war</packaging>
添加Tomcat依賴：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
最后，我們通過實現(xiàn)SpringBootServletInitializer接口來初始化Tomcat所需的Servlet上下文：
@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);
}
}

該文檔明確指出您必須在 pom.xml中將包裝標簽從pom更改為war
