spring boot 关闭默认的spring security

spring boot 和activiti集成的时候，关闭默认开启的security。

package com;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.orm.jpa.vendor.HibernateJpaSessionFactoryBean;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication(exclude = {
		org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class,
		org.activiti.spring.boot.SecurityAutoConfiguration.class })
@ServletComponentScan(basePackages = {"com.activiti.filter"})
public class DemoActiviti0108Application {
	
	@Bean
    public HibernateJpaSessionFactoryBean sessionFactory() {
        return new HibernateJpaSessionFactoryBean();
    }

	public static void main(String[] args) {
		SpringApplication.run(DemoActiviti0108Application.class, args);
	}

}
