我有一个带有启动控制器的Spring Boot应用程序和一个Angular应用程序作为前端。 目前它们都在localhost中运行,并且SpringSecurity已启用。 最初,由于Cors,我无法从Angular到Spring进行getRequest。我在我的restContoller中添加了@CrossOrigin,现在我可以执行从angular到Spring的Get请求。 现在,我对发布请求有同样的问题。我想将一些表单数据从angular发送到Spring,但是在Chrome中总是出现错误。我也在这里添加了@CrossOrigin,但是我仍然遇到问题。 如果我尝试与邮递员进行邮寄请求,则效果很好
zone.js:3243从源'http://localhost:4200'在'localhost:8080 / rest / contact'处对XMLHttpRequest的访问已被CORS策略阻止:协议方案仅支持跨源请求:http,数据,chrome,chrome扩展名,https。
contact.component.ts:51 HttpErrorResponse {headers:HttpHeaders,status:0,statusText:“ Unknown Error”,url:“ localhost:8080 / rest / contact”,ok:false,...}
这是我的安全配置:
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private CustomUserDetailsService userDetailsService;
@Override
protected void configure (AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService)
.passwordEncoder(getPasswordEncoder());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors();
http
.authorizeRequests()
.antMatchers("/admin/**").authenticated()//.hasAnyRole("ADMIN","USER")
.and().formLogin().loginPage("/login").permitAll()
.and().logout();
http.csrf().disable();
//http.headers().frameOptions().disable();
}
private PasswordEncoder getPasswordEncoder() {
return new PasswordEncoder() {
@Override
public String encode(CharSequence charSequence) {
return charSequence.toString();
}
@Override
public boolean matches(CharSequence charSequence, String s) {
return encode(charSequence).equals(s);
}
};
}
}
我的Cors配置:
@Configuration
public class CorsConfiguration {
@Bean
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurerAdapter() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
};
}
}
我的休息控制器:
@RestController()
@CrossOrigin(origins = "http://localhost:4200/**", maxAge = 3600)
public class GymRestController {
private final GymRepository gymRepository;
GymRestController (GymRepository gymRepository) {
this.gymRepository = gymRepository;
}
@GetMapping("/rest/gyms")
public List<Gym> findAll() {
return gymRepository.findAll();
}
@PostMapping ("/rest/contact")
public void submitContact(@RequestBody ContactForm contactForm) {
System.out.println(contactForm);
}
}
和我在angular中的on Submit方法
onSubmit() {
this.submitted = true;
if (this.messageForm.invalid) {
return;
}
this.success = true;
this.contactModel.fromName = this.messageForm.get('name').value;
this.contactModel.fromMail = this.messageForm.get('email').value;
this.contactModel.subject = this.messageForm.get('subject').value;
this.contactModel.message = this.messageForm.get('message').value;
let url = "http://localhost:8080/rest/contact";
// let url = "https://cors.io/?localhost:8080/rest/contact"
this.http.post(url, this.contactModel).subscribe(
res => console.log("success"),
error => console.log(error),
() => console.log("complete")
);
}
我一直在尝试3天,以使它正常运行 任何帮助将不胜感激

跟随Spring io链接: https://spring.io/blog/2015/06/08/cors-support-in-spring-framework
如果您使用的是Spring Boot,建议仅声明一个WebMvcConfigurer bean,如下所示:
@Configuration
public class MyConfiguration {
@Bean
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurerAdapter() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
};
}
}
您可以轻松更改任何属性,以及仅将此CORS配置应用于特定的路径模式:
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/api/**")
.allowedOrigins("http://domain2.com")
.allowedMethods("PUT", "DELETE","POST")
.allowedHeaders("header1", "header2", "header3")
.exposedHeaders("header1", "header2")
.allowCredentials(false).maxAge(3600);
}
以上,您可以将http://domain2.com替换为您的本地主机或所需的主机/ URL。

我终于找到了解决方案。我必须在Spring Security中启用cors并禁用csrf
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.cors().and()
.authorizeRequests()
.antMatchers("/admin/**").authenticated()//.hasAnyRole("ADMIN","USER")
.and().formLogin().loginPage("/login").permitAll()
.and().logout();
http.csrf().disable();
http.headers().frameOptions().disable();
}
我必须从控制器中删除@CrossOrigin,并添加了以下配置:
@Configuration
public class CorsConfiguration {
@Bean
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurerAdapter() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedMethods("*")
.allowedOrigins("http://localhost:4200");
}
};
}
}
