您好，我最近使用STS4创建了一个微服务post API调用，该调用已成功构建和部署。localhost:8080/demo/链接正在打开。但其下的其余映射失败，未找到404。我已经添加了请求映射和post映射，但仍然不能正常工作。有人能修复代码吗？

PFB代码：- POM:-

下面是swagger的配置:-

package com.example.demo;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration  
//Enable Swagger  
@EnableSwagger2 
public class SwaggerConfig {
  
  @Bean  
  public Docket api() {  
     //creating constructor of Docket class that accepts parameter DocumentationType  
     return new Docket(DocumentationType.SWAGGER_2);  
  }
}

下面是rest控制器：

package com.example.demo.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.example.demo.model.MyResponse;
import com.example.demo.service.dao.DemoServiceDAO;
import com.example.demo.service.impl.DemoServiceImpl;

@RestController
@Validated
@RequestMapping(value ="/newcall", method = RequestMethod.POST)
public class DemoController {
  Logger logger =LoggerFactory.getLogger(DemoController.class);
  
  @PostMapping(value ="/newResp", headers ="Accept=Application/JSON", produces="Application/JSON")
  public MyResponse newResp(@RequestBody String myInput) {
    MyResponse myResponse = null;
    try {
      DemoServiceDAO demoServiceDAO = new DemoServiceImpl();
      logger.debug("Started getValue() method...");
      myResponse=demoServiceDAO.getValue(myInput);
      logger.debug("Completed getValue() method...");
      
    }
    catch(Exception e){
      logger.debug("Exception occurs",e);
      e.printStackTrace();
      System.out.println("Exception occurs");
    }       
    return myResponse;
  }
}

以下是应用程序：

package com.example.demo;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@SpringBootApplication
@ComponentScan(basePackages = "com.example.*")
@EnableSwagger2
public class DemoApplication extends SpringBootServletInitializer {

  public static void main(String[] args) {
    Logger logger =LoggerFactory.getLogger(DemoApplication.class);
    SpringApplication.run(DemoApplication.class, args);
  }
}

这里是app.properties:-

    logging.file.name=opt/var/logs/demoService.log
    logging.file.path=opt/var/logs
    logging.level.web=DEBUG
    spring.jmx.default-domain=demo
    server.servlet.context-path=/demo
    management.endpoints.web.exposure.include=*
    management.endpoint.health.show-details=always
    
    springfox.documentation.swagger-ui.base-url=true
    management.endpoint.info.enabled: true
    springfox.documentation.swagger-ui.enabled=true
    springfox.documentation.open-api.enabled=true
    spring.security.user.name = user
    spring.security.user.password = password

来自http://localhost:8080/demo/的输出

     "_links" : {
       "profile" : {
          "href" : "http://localhost:8080/demo/profile"
        }
     }

没有任何日志，我们只能猜测，但是看着你的控制器，我看到了一些奇怪的事情。你能试一下下面的方法吗？

@RestController
@Validated
@RequestMapping("newcall")
public class DemoController {
  Logger logger =LoggerFactory.getLogger(DemoController.class);
  
  @PostMapping("/newResp", consumes = "application/json", produces = application/json)
  public MyResponse newResp(@RequestBody String myInput) {
    MyResponse myResponse = null;
    try {
      DemoServiceDAO demoServiceDAO = new DemoServiceImpl();
      logger.debug("Started getValue() method...");
      myResponse=demoServiceDAO.getValue(myInput);
      logger.debug("Completed getValue() method...");
      
    }
    catch(Exception e){
      logger.debug("Exception occurs",e);
      e.printStackTrace();
      System.out.println("Exception occurs");
    }       
    return myResponse;
  }
}
