springboot-31-springboot静态注入

springboot中 使用 @Autowired 注入时, 是可以为静态变量进行注入的

package com.iwhere.footmark.tools;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Component;

/**
 * 测试静态注入
 * @author wenbronk
 * @time 2017年8月30日 上午9:40:00
 */
@Component
public class StaticTest {

    private static StringRedisTemplate redis;
    @Autowired
    public void setRedis(StringRedisTemplate redis){
        StaticTest.redis = redis;
    }
    
    public static void setGet() {
        String key = "abc";
        ValueOperations<String, String> opsForValue = redis.opsForValue();
        opsForValue.set(key, "static_test_value");
        String string = opsForValue.get(key);
        System.out.println(string);
    }
    
}

然后, 调用的方式为: 

    @Autowired
    private TestService TestService;

    @RequestMapping("/")
    public String test() {
    //    String test = TestService.test();
        StaticTest.setGet();
        return test;
    }

也可以在 application.yml中的常量, 使用静态注入: 

package com.iwhere.footmark.properties;

import java.util.ArrayList;
import java.util.List;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

/**

        List<String> result = new ArrayList<>();
        result.add(bgmUrl);
        result.add(bgmUrl2);
        result.add(bgmUrl3);
        return result;
    }

    public static Integer getFootDefaultLevel() {
        return footDefaultLevel;
    }

    public static void setFootDefaultLevel(Integer footDefaultLevel) {
        ConstanceProperties.footDefaultLevel = footDefaultLevel;
    }

    public static Integer getFootMarkGeoLevel() {

    }

    public static Integer getFootMarkMax() {
        return footMarkMax;
    }

    public static void setFootMarkMax(Integer footMarkMax) {
        ConstanceProperties.footMarkMax = footMarkMax;
    }

    public static String getTemplateCode() {
        return templateCode;
    }

    public static void setTemplateCode(String templateCode) {

    }

    }

    public static void setDefaultImgUrl(String defaultImgUrl) {

    }

    public static String getBgmUrl2() {
        return bgmUrl2;
    }

    public static void setBgmUrl2(String bgmUrl2) {
        ConstanceProperties.bgmUrl2 = bgmUrl2;
    }

    public static String getBgmUrl3() {
