尝试在外部在tomcat 9上运行带有rest控制器的spring boot war文件

【中文标题】尝试在外部在tomcat 9上运行带有rest控制器的spring boot war文件

【英文标题】：Trying to run a springboot war file with rest controller on tomcat 9 externally

【发布时间】：2019-07-08 07:04:04

【问题描述】：

我一直在尝试部署 springboot 应用程序。我尝试了一个，可以成功地将带有rest控制器的springboot部署到嵌入式tomcat。现在我正在尝试另一种方法，我想将它打包为一个 Web 应用程序项目并部署到 tomcat。我能够部署它，但它不能正确解析休息控制器路径并给出 http 404 错误。我正在使用 gradle build 来执行此操作。

contextpath 属性不起作用。

我的应用程序在 http://localhost:8080/projectName/Welcome.jsp 启动。我需要在外部提供这个。它试图通过点击我在 jsp 中的链接移动到 http:localhost:8080/students。

这给出了错误 - 类型状态报告

我的休息控制器很简单

@RestController
@RequestMapping(value="/students")
public class StudentController 

private StudentServiceImplWithoutDB studentService;

@Autowired
public StudentController(StudentServiceImplWithoutDB studentService) 
    this.studentService = studentService;



@GetMapping
public List<StudentVO> getAll()

    List<StudentVO> studentVO= studentService.getAllStudents();
    return studentVO;

我需要为战争设置任何路径或属性吗？几乎相同的应用程序在简单的 java 应用程序中嵌入 tomcat 就像一个魅力

【问题讨论】：

我认为您需要从 compile("org.springframework.boot:spring-boot-starter-web") exclude module: "spring-boot-starter-tomcat" 等依赖项中删除嵌入式 tomcat

它不起作用。它仍然存在上下文 404 问题

你必须这样做 在 Spring Boot 中禁用嵌入式 Tomcat 将包类型更改为 WAR 在主应用程序类中扩展 SpringBootServletInitializer 将 WAR 文件上传到 Tomcat webapps 目录

【参考方案1】：

首先你必须在gradle中提供tomcat作为provideRunTime，然后将包类型更改为war，然后在主类中扩展SpringBootServletInitializer，将war文件上传到tomcat web文件夹

按照这些步骤

先在gradle中添加

providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'

更改包类型

apply plugin: "war"

在主类中扩展 SpringBootServletInitializer 类

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;

@SpringBootApplication
public class Application extends SpringBootServletInitializer 

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

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