shiro abnormal UnavailableSecurityManagerException

Yesterday anomaly on the title tune appears in the program

The next check is like saying SecurityManager related issues

Then I saw the code:

    @Bean(name = "securityManager")
    public SecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //设置自定义realm.
        securityManager.setRealm(getDatabaseRealm());
        //配置记住我
        securityManager.setRememberMeManager(rememberMeManager());
        SecurityUtils.setSecurityManager(securityManager);
        return securityManager;
    }

SecurityUtils.setSecurityManager (securityManager) before this line is commented out
and see inside SecurityUtils

public static SecurityManager getSecurityManager() throws UnavailableSecurityManagerException {
        SecurityManager securityManager = ThreadContext.getSecurityManager();
        if (securityManager == null) {
            securityManager = securityManager;
        }

        if (securityManager == null) {
            String msg = "No SecurityManager accessible to the calling code, either bound to the " + ThreadContext.class.getName() + " or as a vm static singleton.  This is an invalid application configuration.";
            throw new UnavailableSecurityManagerException(msg);
        } else {
            return securityManager;
        }
    }

getSecurityManager () It is the exception thrown

In SecurityManager join the line that begins with the disappearance of abnormal

        SecurityUtils.setSecurityManager(securityManager);

Then I think the reason may appear before the code changes I added a method to control layer multi-threaded processing and configuration:

package com.tansuo365.test1.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.task.TaskExecutor;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.ThreadPoolExecutor;

@Configuration
@EnableAsync
public class AsyncConfig {

    @Bean
    public TaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor executor = newThe ThreadPoolTaskExecutor is ();
         // Set the number of core threads 
        executor.setCorePoolSize (. 5 );
         // set the maximum number of threads 
        executor.setMaxPoolSize (10 );
         // set the queue capacity 
        executor.setQueueCapacity (20 is );
         // Set the thread active time (sec ) 
        executor.setKeepAliveSeconds (60 );
         // set the default thread name 
        executor.setThreadNamePrefix ( "danhao-" );
         // set deny policy 
        executor.setRejectedExecutionHandler ( new new ThreadPoolExecutor.CallerRunsPolicy ());
         // wait for all tasks to close before the end of the Thread Pool
        executor.setWaitForTasksToCompleteOnShutdown(true);
        return executor;
    }
}

    @Async
    @RequestMapping("/getChukuNumber")
    public ListenableFuture<String> genBillCode(String type) throws Exception {
        StringBuffer billCodeStr = new StringBuffer();
        billCodeStr.append(chukudanPrefix);
        billCodeStr.append(DateUtil.getCurrentDateStr());
        String todayMaxChukuDanNumber = chukuZongService.getTodayMaxChukuDanNumber();
        if (todayMaxChukuDanNumber != null) {
            billCodeStr.append(StringUtil.formatCode(todayMaxChukuDanNumber));
        } else {
            billCodeStr.append("0001");
        }
        return new AsyncResult<>(billCodeStr.toString());
//        return billCodeStr.toString();
    }

If you want to enable but also in the springboot filling Note:

//@EnableCaching
@SpringBootApplication
@MapperScan(value = {"com.xxxxxxx.test1.mapper"})
@EnableAsync//开启异步任务
public class Test1Application {

    public static void main(String[] args) {
        SpringApplication.run(Test1Application.class, args);
    }

}

The end of the problem
