AWS服务器Spring Boot REST API状态500不支持请求方法“GET”

Question

我的 Rest API 在本地运行良好，但当我放入相同的 JAR 并从云服务器运行它时，我只能调用 GET API 而不能从 Postmen 调用 POST API。

下面是我的代码。

RestController

@CrossOrigin(origins = "*", maxAge = 3600)
@RestController
@RequestMapping("/api/test")
public class TestController {

@GetMapping("/all")
public String allAccess() {
    return "Public Content.";
}

@PostMapping("/testpostA")
public ResponseEntity<?> testPostA() {
    return ResponseEntity.ok(new MessageResponse("Test POST successfully!"));
}

@PostMapping("/testpostB")
public String testPostB() {
    return "String return POST successfully.";
}
}

WebSecurityConfigurationAdapter

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(
    // securedEnabled = true,
    // jsr250Enabled = true,
    prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
UserDetailsServiceImpl userDetailsService;

@Autowired
private AuthEntryPointJwt unauthorizedHandler;

@Bean
public AuthTokenFilter authenticationJwtTokenFilter() {
    return new AuthTokenFilter();
}

@Override
public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
    authenticationManagerBuilder.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}

@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}

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

@Override
protected void configure(HttpSecurity http) throws Exception {
    System.out.println("============================ Inside WebSecurityConfig ===========================Ken");
    http.csrf().disable().authorizeRequests().anyRequest().permitAll();
}}

最后，网络应用程序：

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

在本地运行相同的 JAR 文件，调用所有 POST 和 GET API 没有问题。但是，当我们将同一个 JAR 移动到 AWS EC2 云实例并运行它时，我们只能调用 GET API。在调用任何 POST API 时，Postmen 控制台会抛出以下错误：

但是，调用 GET API 时没有问题：

服务器控制台输出 - 没有错误：

更新 - 第 1 轮

使用 wget 测试，错误 500 也是如此。没有更多信息。

更新 - 第 2 轮 使用 wget POST 进行测试，并在修改 WebSecurityConfig 之后进行测试。这是截图：

服务器控制台在 wget POST 时包含警告：

WebSecurityConfig 的更新代码：

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Override
public void configure(HttpSecurity http) throws Exception {

    http.cors().and().csrf().disable();
}
}

Answer 1

试试这样的配置：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class CorsConfig {

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedMethods("HEAD", "GET", "PUT", "POST", "DELETE", "PATCH");
            }
        };
    }
}

Answer 2

问题是由于 Nginx 反向代理处理造成的。在 localhost 中，我使用的是 HTTP，但在开发服务器中，我们只使用 HTTPS。因此，我对所有 RESTful API URL 使用了 HTTPS。
