The difference between cross-domain configuration between Spring boot 2.0 and previous versions 2.0

1. Introduction

After spring boot was upgraded to 2.0, it was found that inheriting WebMvcConfigurerAdapter to achieve cross-domain obsolete, then we followed the trend.

2. Global configuration

　　Before 2.0, cross-domain request codes were supported:

 1 import org.springframework.context.annotation.Configuration;  
 2 import org.springframework.web.servlet.config.annotation.CorsRegistry;  
 3 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;  
 4   
 5 /** 
 6  * 说明：跨域请求 
 7  * 
 8  * @author WangBin 
 9  * @version v1.0 
10  * @date 2018/1/21/ 
11  */  
12 @Configuration  
13 public class CorsConfig extends WebMvcConfigurerAdapter {  
14   
15     @Override  
16     public void addCorsMappings(CorsRegistry registry) {  
17         registry.addMapping("/**")  
18                 .allowedOrigins("*")  
19                 .allowCredentials(true)  
20                 .allowedMethods("*")  
21                 .maxAge(3600);  
22     }  
23 }  

Version 2.0 is as follows:

 1 import org.springframework.context.annotation.Configuration;  
 2 import org.springframework.web.servlet.config.annotation.CorsRegistry;  
 3 import org.springframework.web.servlet.config.annotation.EnableWebMvc;  
 4 import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;  
 5   
 6 /** 
 7  * 说明：跨域请求 
 8  * 
 9  * @author WangBin 
10  * @version v1.0 
11  * @date 2018/1/21/ 
12  */  
13 @Configuration  
14 @EnableWebMvc  
 15  public  class CorsConfig implements WebMvcConfigurer {  
 16    
17      @Override  
 18      public  void addCorsMappings(CorsRegistry registry) {  
 19          // Set the path that allows cross-domain   
20          registry.addMapping("/**" )  
 21                  // Set to allow cross-domain requests The domain name   
22                  .allowedOrigins("*" )  
 23                  // Whether the certificate is no longer enabled by default   
24                  .allowCredentials( true )  
 25                  // Set the allowed method   
26                 .allowedMethods("*" )  
 27                  // Cross-domain allowed time   
28                  .maxAge(3600 );  
 29      }  
 30 }
