Springboot-Get the application context ApplicationContext and build the tool class

1. Implement Applicationcontextaware interface

Import Com.simply.zuozuo.util.ApplicationContextUtils; Import Lombok.
Data;
Import lombok.extern.slf4j.Slf4j;
Import org.springframework.beans.BeansException;
Import Org.springframework.context.ApplicationContext;
Import Org.springframework.context.ApplicationContextAware;
Import org.springframework.lang.Nullable;

Import org.springframework.stereotype.Component; /** * @author Created by Tan Jian on 2018/4/13 0013. Friday.
 11:29. *©all Rights Reserved.  * * @Slf4j @Component @Data public class Applicationcontextawareimpl implements Applicationcontextaware {/** * Implement this interface to initialize the application context * The interface is executed after the @postconstruct method is executed * <p> * Then the mapper address is scanned and loaded, which is specified in requestmapping  Path * * @param applicationcontext Application context * @throws beansexception Beans Exception/@Override public void Setapplicationcontext (@Nullable applicationcontext applicationcontext) throws Beansexception {Log.info ("Application
        Sequence context: [{}] ', ' initiating initialization '; Applicationcontextutils.applIcationcontext = ApplicationContext;
        Log.info ("Application context GetId: [{}]", Applicationcontext.getid ());
        Log.info ("Application context Getapplicationname: [{}]", Applicationcontext.getapplicationname ());
        Log.info ("Application context Getautowirecapablebeanfactory: [{}]", applicationcontext.getautowirecapablebeanfactory ());
        Log.info ("Application context GetDisplayName: [{}]", Applicationcontext.getdisplayname ());
        Log.info ("Application context GetParent: [{}]", applicationcontext.getparent ());
        Log.info ("Application context Getstartupdate: [{}]", applicationcontext.getstartupdate ());

        Log.info ("Application context getenvironment: [{}]", applicationcontext.getenvironment ());
    Log.info ("Application context: [{}]", "initialization Complete"); }
}

2. Building Tool Class

Import Org.springframework.context.ApplicationContext;

/**
 * @author Created by Tan Jian on 2018/4/13 0013. Friday. 11:47.
 *©all Rights Reserved.
 * * Public
class Applicationcontextutils {public


    static applicationcontext ApplicationContext;

    /**
     * Get bean/public
    static Object gets (String name) {return
        Applicationcontext.getbean (name) by name;
    }


    /**
     * Get bean by type
    /public static Object getting (class<?> clazz) {
        return Applicationcontext.getbean (Clazz);
    }

    /**
     * To determine if a bean exists *
    /public static Boolean has (String name) {
        return Applicationcontext.containsbean (name);
    }
