修改sa-token检查token的报错信息

1.创建一个类去实现 NotLoginExceptionMapper

import cn.dev33.satoken.exception.NotLoginException;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype
@Component
public class CustomNotLoginExceptionMapper implements NotLoginExceptionMapper {

    @Override
    public ResponseEntity<Object> toResponse(NotLoginException e) {
        // 自定义处理逻辑，例如返回自定义的错误信息或进行其他操作
        String errorMessage = "您没有登录";
        return new ResponseEntity<>(errorMessage, HttpStatus.UNAUTHORIZED);
    }
}

2.启动类添加注解确保自定义的类可以被扫描到

@ComponentScan("com.example") // com.example替换为上面那个类的包路径

3.将之作为bean在启动类注册

@SpringBootApplication
@ComponentScan("com.example")
public class YourApplication {

    public static void main(String[] args) {
        SpringApplication.run(YourApplication.class, args);
    }

    @Bean
    public CustomNotLoginExceptionMapper customNotLoginExceptionMapper() {
        return new CustomNotLoginExceptionMapper();
    }

}
