不支持请求方法“GET”出现意外错误（类型=不允许的方法，状态=405）

Question

我的场景如下：有几个实体，我需要为每个实体“按 Id ”发送定制设计的 email。 For example, I am trying to send the email by this URL for "babs" entity: http://localhost:8081/api/v1/test/babss/sendmail/b1d0c331-35ac-430d-87ca-1718b06351c3

BaBS 的示例实体：

    import com.fasterxml.jackson.annotation.JsonBackReference;
import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.*;
import javax.persistence.*;
import java.util.UUID;

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@Builder
@Entity
@Table(name = "babs")
public class BaBs {

@Id
@Column(name = "id")
private UUID id;

@Column(name = "accountCode")
private String accountCode;

@Column(name = "accountName")
private String accountName;

@Column(name = "eMail")
private String eMail;

@ManyToOne
@JsonBackReference
@JoinColumn(name = "accountid")
private Account account;

}

email 寄送服务

    import gokhan.mutabakatcore.models.BaBs;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

@Component
public class SentBaBsEmail {

@Autowired
private JavaMailSender sender;

public HttpStatus mailBaBs(BaBs baBs) throws MailException {
    SimpleMailMessage mail = new SimpleMailMessage();
    mail.setTo(baBs.getEMail());
    mail.setSubject("Trial Mail for Sending BaBs");
    mail.setText("Normally Details from Object ");
    sender.send(mail);
    System.out.println("eMail sent");
    return HttpStatus.GONE;
}

}

BaBS对应部分Controller

    import gokhan.mutabakatcore.models.BaBs;
import gokhan.mutabakatcore.services.BaBsService;
import gokhan.mutabakatcore.utils.SentBaBsEmail;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.HttpServletRequest;
import javax.validation.Valid;
import java.util.Collections;
import java.util.List;
import java.util.Optional;
import java.util.UUID;
import java.util.function.Function;

@RestController
@RequestMapping("/api/v1/test/babss")
public class BaBsController {
private final BaBsService baBsService;

public BaBsController(BaBsService baBsService) {
    this.baBsService = baBsService;
}

@Autowired
SentBaBsEmail baBsEmail;

@RequestMapping(value = "/sendmail/{Id}", method = { RequestMethod.GET, RequestMethod.POST })
public ResponseEntity<?> eMailBaBsByCustomerId(@PathVariable("Id") UUID uuid){
    try{
        if (!baBsService.findById(uuid).equals(Optional.empty())){

            // Converts Optional Object to Normal Object
            BaBs baBs = (BaBs) toList(baBsService.findById(uuid));
            baBsEmail.mailBaBs(baBs);
            return new ResponseEntity(baBs ,HttpStatus.CREATED);
        }
        return new ResponseEntity<>("Unrecorded BaBS!", HttpStatus.BAD_REQUEST);
    } catch (Exception e) {
        return new ResponseEntity<>(HttpStatus.NOT_FOUND);
    }
}
}

Application.properties 邮件部分

    #SMTP Email Properties
spring.mail.host=mail.xyz.com
spring.mail.port=587
spring.mail.username=info@xyz.com
spring.mail.password=password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.starttls.enable=true
spring.mail.properties.mail.starttls.required=true

相关 POM.xml 依赖项

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

我得到的错误：

    This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Method Not Allowed, status=405).
Request method 'GET' not supported
org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'GET' not supported

如果你能告诉我这个问题，我将不胜感激......
