Question

我的Spring Boot应用程序中出现异常PageNotFound: Request method 'POST' not supported。

这是我的控制者：

@RestController
public class LoginController {

UserWrapper userWrapper = new UserWrapper();

@RequestMapping(value = "/api/login", method = RequestMethod.POST, headers = "Content-type: application/*")
public @ResponseBody ResponseEntity getCredentials(@RequestBody UserDTO userDTO) {

    User user = userWrapper.wrapUser(userDTO);
    if (userDTO.getPassword().equals(user.getPassword())) {
        return new ResponseEntity(HttpStatus.OK);
    } else {
        return new ResponseEntity(HttpStatus.BAD_REQUEST);
    }
  }
}

我在localhost:8080/api/login发送邮件请求，但它不起作用。你有什么想法吗？

修改

UserDTO：

public class UserDTO implements Serializable {

private String email;
private String password;
//getters and setters

我和json发送：

{
   "email":"email@email.com",
   "password":"password"
}

Answer 1

我通过禁用CSRF解决了这个问题。

@Configuration
class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
    }
 }

我解决了我的问题。我从RequestMapping中删除了标题，并为@Autowired添加了UserWrapper注释，现在一切正常。

如果您使用的是JPA，则会出现此问题。 Spring引导存储库内置了所有请求。因此您的请求必须匹配存储库请求这是我发现的唯一具有可用Spring Boot POST的示例 https://dzone.com/articles/crud-using-spring-data-rest 关键是您必须匹配存储库休息调用

您的存储库Iterface看起来像这样加上任何覆盖没有impl类

public interface UseerRepository extends  CrudRepository<User, Integer>{
}

您的控制器将如下所示。请注意请求值 / users 它是末尾带有S的实体名称

@RestController
public class LoginController {

@RequestMapping("/api/login")//this will return the login page
public String home() {
    return "login";
}
UserWrapper userWrapper = new UserWrapper();
//this will do the post
@RequestMapping(value = "/users", method = RequestMethod.POST,    headers = "Content-type: application/*")
public @ResponseBody ResponseEntity getCredentials(@RequestBody UserDTO userDTO) {

User user = userWrapper.wrapUser(userDTO);
if (userDTO.getPassword().equals(user.getPassword())) {
    return new ResponseEntity(HttpStatus.OK);
} else {
    return new ResponseEntity(HttpStatus.BAD_REQUEST);
}
  }
}

您的应用程序配置文件应如下所示通知@ComponentScan no basepackage = {“com”}如果您这样做，那么您的JPA无法正常工作

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.context.annotation.PropertySource;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration;


@Configuration
@ComponentScan
@EnableJpaRepositories
@Import(RepositoryRestMvcConfiguration.class)
@EnableAutoConfiguration
@PropertySource("application.properties")
public class Application {

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

如果要覆盖存储库POST请求在控制器或服务类中执行，我希望我解释得很好，但该示例确实有效，您不必再编写大量原始代码了
