Question

我一直在尝试部署springboot应用程序。我尝试了一个，可以将带有rest控制器的springboot部署到嵌入式tomcat中。现在，我再尝试将其打包为Web应用程序项目并部署到tomcat。我能够部署它，但是它不能正确解析以休息控制器路径并给出http 404错误。我正在使用gradle build进行此操作。

contextpath属性不起作用。

我的应用程序在http://localhost:8080/projectName/Welcome.jsp上启动。我需要从外部给它。单击我在jsp中的链接后，它会尝试移动到http：localhost：8080 / students。

这给出了错误-类型状态报告

消息/学生

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？对于简单的Java应用程序，几乎相同的应用程序都具有嵌入的tomcat的魅力

Answer 1

首先，必须在将包类型更改为war之后，在gradle中提供tomcat作为ProvideRunTime，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

首先添加gradle

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

更改程序包类型

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);
  }
}
