英文:
Springboot Cors config - MyApplication and WebConfig
问题
我的Spring Boot应用程序最终有两个类，它们都有CORS配置。
我认为其中一个是不必要的。有人能解释为什么会有两个吗？
MyApplication类：
@EntityScan("com.nz.myapp")
@SpringBootApplication(exclude = {SecurityAutoConfiguration.class})
public class MyApplication {
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurer() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
};
}
}
WebConfig类：
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
}
英文:
My Spring Boot application has ended up with two classes that both have cors configuration in them.
I presume one of them is unnecessary. Can someone explain why there is both?
MyApplication:
@EntityScan("com.nz.myapp")
@SpringBootApplication(exclude = {SecurityAutoConfiguration.class })
public class MyApplication {
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurer() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
};
}
WebConfig
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
}

WebMvcConfigurerAdapter已被弃用，不应再使用它。只需使用WebMvcConfigurer的实现：
@Configuration(proxyBeanMethods = false)
public class WebConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
}
然而，以后您可能仍然会在SecurityFilterChain中设置CORS配置，因此WebMvcConfigurer更可能用于设置资源处理程序和格式化程序。
英文:
The WebMvcConfigurerAdapter is deprecated, you shouldn't use it anymore. Just stick with an implementation of WebMvcConfigurer:
@Configuration(proxyBeanMethods = false)
public class WebConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**");
}
}
However, later on you might set CORS configuration inside your SecurityFilterChain anyway, so the WebMvcConfigurer might more likely be used to set up resource handlers and formatters.
