springboot+shiro遇到的问题

问题：

No SecurityManager accessible to the calling code, either bound to the
org.apache.shiro.util.ThreadContext or as a vm static singleton. This
is an invalid application configuration.

解决：

package com.demengshop;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Component;


@SpringBootApplication
@Component	//在启动类加上这个注解
public class WebApp {
    public static void main(String[] args) {
        SpringApplication.run(WebApp.class,args);
    }
}
