【问题描述】：
我运行一个 WAMP 服务器和一个包含 Angular 应用程序和 Springboot 应用程序的 tomcat 服务器。我有 404，而我认为我满足所有要求，不会出现此类问题。同时，我的前端应用程序正在返回 cors 错误。
- 在我的pom xml中添加依赖来生成war
- 更新我的主类以允许战争生成
- 管理对公共路线的访问
- 处理 cors 管理
- 在 WebSecurity 中管理 Cors
我有这个 pom.xml ：

我还在 application.properties 中定义了一些参数（甚至是上下文路径）：
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql://localhost:3306/my-db
spring.jpa.hibernate.ddl-auto=update
server.port=8080
spring.h2.console.enabled=true
server.servlet.context-path=/springboot-proxy
没什么特别的。由于要建jar，所以不忘修改主类：
@SpringBootApplication
public class SpringbootProxyApplication extends SpringBootServletInitializer {
// allow to generate a war file
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(SpringbootProxyApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(SpringbootProxyApplication.class, args);
}
这很好。由于它是一个休息 API，我还添加了一个 get 调用以用于测试目的：
@Slf4j
@RestController
@RequestMapping("/ws")
public class DummyController {
@GetMapping
public String dummy() throws IOException {
return "Hello World";
}
}
我实现了 Spring Security，我希望这些路由是公开的，所以我实现了配置方法
@Override
protected void configure(HttpSecurity http) throws Exception {
// define public & private entry points
http
.cors().and()
.csrf().disable()
.authorizeRequests()
.antMatchers(HttpMethod.GET, "/ws").permitAll()
.antMatchers(HttpMethod.POST, "/ws/**").permitAll()
在运行我的 mvn clean 包时，我会构建我的 API。我确实使用tomcat管理器上传了我的jar。它工作正常。当然，我还添加了 Cors 管理...
我在我的网络安全中实现了这一点：
public CorsConfigurationSource corsConfigurationSource() {
final CorsConfiguration corsConfiguration = new CorsConfiguration();
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
corsConfiguration.setAllowedOrigins(Collections.singletonList("*"));
corsConfiguration.setAllowedMethods(Collections.singletonList("*"));
corsConfiguration.setAllowCredentials(true);
corsConfiguration.setAllowedHeaders(Arrays.asList("Authorization", "Cache-Control", "Content-Type"));
source.registerCorsConfiguration("/**", corsConfiguration);
return source;
}
如果还不够：
@Configuration
public class WebConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry
.addMapping("/**")
.allowedMethods("*")
.allowedOrigins("*");
}
}
在我面前我有这样的回应：
Access to XMLHttpRequest at 'http://localhost:8080/springboot-proxy/ws/getCategories' from origin 'http://localhost' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
当我尝试从我的 dummyController 调用 get 方法时，我遇到了一个不错的 404 错误。我真的不明白出了什么问题...
