Springboot请求方法'POST'不受支持
我刚刚开始学习用于REST API开发的Java Spring Boot。使用下面的代码,GET方法可以正常工作,但POST无法正常工作。
@RestController@RequestMapping("/api/users")
public class UsersController {
@Autowired
private UserRepository userRepository;
@RequestMapping(method = RequestMethod.GET)
public List<User> getAll() {
return userRepository.findAll();
}
@RequestMapping(method = RequestMethod.POST)
public String saveUser() {
return "Saved";
}
}
在Postman应用程序中使用Content-Type
as 测试了POST方法application/json
错误,
{ "timestamp": 1497116929266,
"status": 405,
"error": "Method Not Allowed",
"exception": "org.springframework.web.HttpRequestMethodNotSupportedException",
"message": "Request method 'POST' not supported",
"path": "/api/users/"
}
在日志中,我可以看到,

适用于Maven的Java和springboot版本,
<parent> <groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.4.RELEASE</version>
<relativePath/>
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
回答:
最后,通过使用maven命令运行项目来解决该问题。
而不是使用IDE的运行按钮运行项目,而是转到IDE中的终端并执行命令
mvn spring-boot:run
由于它是一个REST
实现,因此我现在可以访问它们,
GET /api/users/ or /api/usersPOST /api/users/ or /api/users
像魅力一样工作!
