今天配置了跨域，但是出现了一下错误

java.lang.IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.

翻译的意思为：

解决办法为：allowedOrigins替换成.allowedOriginPatterns

未替换的代码为：

package com.example.springboot.config;

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

@Configuration
public class CorsConfig extends WebMvcConfigurerAdapter {

    static final String ORIGINS[] = new String[]{"GET", "POST", "PUT", "DELETE"};

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").
                allowedOrigins("*").
                allowCredentials(true).
                allowedMethods(ORIGINS).
                maxAge(3600);
    }
}

替换后的代码为：

package com.example.springboot.config;

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

@Configuration
public class CorsConfig extends WebMvcConfigurerAdapter {

    static final String ORIGINS[] = new String[]{"GET", "POST", "PUT", "DELETE"};

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").
                allowedOriginPatterns("*").
                allowCredentials(true).
                allowedMethods(ORIGINS).
                maxAge(3600);
    }
}

单纯记录自己出现的问题。
