代码调整

import变化

import org.apache.commons.lang.StringUtils;
改为
import org.apache.commons.lang3.StringUtils;

CollectionUtils变化

        set.addAll(CollectionUtils.arrayToList(str.split(",")));
//        set.addAll(CollectionUtils.arrayToList(str.split(",")));//2.0.5

验证变化

Length变为Size

//import org.hibernate.validator.constraints.Length;
import org.checkerframework.checker.units.qual.Length;

注解修改

    //@Length(min = 1, max = 100, message = "发送对象不能为空")
    @Size(min = 1, max = 100, message = "发送对象不能为空")

Shiro

提示ShiroFilterFactoryBean不存在

 //@Bean
    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean factory(SecurityManager securityManager) {

跨域问题

使用addAllowedOrigin导致跨域不成功，提示不允许使用*

//        corsConfiguration.addAllowedOrigin("*");
        //原本是addAllowedOrigin,改为addAllowedOriginPattern
        corsConfiguration.addAllowedOriginPattern("*");

增加启动配置

  @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowCredentials(true).allowedOriginPatterns("*");
            }
        };
    }
