java Spring+Spring安全请求只接受contenttype xwwwformurlencoded

Question

这是我第一次决定用完整的Java代码配置编写基于Spring Boot和Spring Security的应用程序，我遇到了无法超越的奇怪问题。我正在尝试用Postman测试API，我的请求只有在使用内容类型为application/x-www-form-urlencoded时才会被接受。下面我将粘贴我的所有当前配置

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

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    private UserService userService;

    @Autowired
    public SecurityConfig(UserService userService) {
        this.userService = userService;
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userService);
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder(11);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/register/**").permitAll()
                .anyRequest().authenticated()
            .and()
                .formLogin()
            .and()
                .cors()
            .and()
                .csrf()
                    .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
    }

}

@RestController
public class UserController {
    ...    

    @PostMapping(value = "/register")
    public ResponseEntity<Object> registerUser(
            @RequestBody UserRegistrationDto newUser, BindingResult bindingResult) {
       ...
    }

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class UserRegistrationDto {
    private String username;
    private String firstName;
    private String lastName;
    private String email;
    private String password;
    private String passwordRepeat;
}

如果我想登录，我只能用上面提到的内容类型登录。对于应用程序/json我得到了403响应状态。对于/registration端点，如果我从方法参数中删除@RequestBody，那么它可以与应用程序/x-www-form-urlencoded请求一起工作，但是如果我保留它，那么对于这个内容类型，我会得到415，但是如果我尝试使用应用程序/json则会看到403。我还尝试在该端点上方添加@PreAutorize（“permitAll（）”）注释，将httpBasic（）添加到Spring安全配置中，从而将响应状态从403更改为401

我尝试过向该端点发送两个不同的JSON：

{
    "username":"test", 
    "firstName":"Test", 
    "lastName":"Test", 
    "email":"test@test.com",
    "password":"test",
    "passwordRepeat":"test",
    "_csrf":"8b7d4680-5be4-482a-9138-b4eb92a358c1"
}

{
    "newUser": {
        "username":"test", 
        "firstName":"Test", 
        "lastName":"Test", 
        "email":"test@test.com",
        "password":"test",
        "passwordRepeat":"test"
    },
    "_csrf":"8b7d4680-5be4-482a-9138-b4eb92a358c1"
}

当然，每次我都要确保\u csrf与我的API返回的匹配

我使用的是Spring Boot 2.0.1。发布和Spring Security 5.0.3。释放
