### 1.问题报错 ###

--------------------

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.geekplus.hephaestus.wms.shelfscore.ShelfScoreTests2': Unsatisfied dependency expressed through field 'shelfScoreSyn'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.geekplus.hephaestus.wms.api.shelfscoring.ShelfScoreSyn' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: \{@org.springframework.beans.factory.annotation.Autowired(required=true)\}

--------------------

### 2.问题描述： ###

--------------------

遇到这个问题，首先提示Dependency annotations

package com.geekplus.hephaestus.wms.shelfscore;
    
    import com.geekplus.hephaestus.library.sys.AlgoSysConfigUtils;
    import com.geekplus.hephaestus.wms.HephaestusWmsApiApplication;
    import com.geekplus.hephaestus.wms.api.shelfscoring.ShelfScoreFacade;
    import com.geekplus.hephaestus.wms.api.shelfscoring.ShelfScoreSyn;
    import com.geekplus.hephaestus.wms.api.shelfscoring.entity.ShelfScoreResult;
    import com.google.common.collect.ImmutableList;
    import org.junit.Before;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.test.context.junit4.SpringRunner;
    
    import java.util.HashMap;
    import java.util.List;
    import java.util.Map;
    
    /**
     *
     * @author: zhangyu
     */
    
    @RunWith(SpringRunner.class)
    @SpringBootTest(classes = {HephaestusWmsApiApplication.class})  // 指定启动类
    @ComponentScan(basePackages = {"com.geekplus"})
    public class ShelfScoreTests2 {
    
        @Before
        public void prepare() {
            AlgoSysConfigUtils.setValue("hephaestus.debug.enabled", "true");
        }
    
    
        @Autowired
        private ShelfScoreSyn shelfScoreSyn;
    
        @Test
        public void testUpdateShelfScore() {
            shelfScoreSyn.execute();
        }
    }

里面引用了， private ShelfScoreSyn shelfScoreSyn;但是在另外一个类中：

package com.geekplus.hephaestus.wms.api.impl.shelfscoring;
    
    import com.geekplus.hephaestus.dataplatform.common.dao.rms.AthenaBaseShelfMapper;
    import com.geekplus.hephaestus.dataplatform.common.dao.wms.BaseShelfMapper;
    import com.geekplus.hephaestus.dataplatform.common.entity.rms.AthenaBaseShelf;
    import com.geekplus.hephaestus.dataplatform.common.entity.wms.BaseShelf;
    import com.geekplus.hephaestus.library.sys.AlgoSysConfigUtils;
    import com.geekplus.hephaestus.wms.api.shelfscoring.ShelfScoreSyn;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Component;
    import org.springframework.stereotype.Service;
    
    import java.util.List;
    import java.util.Map;
    import java.util.stream.Collectors;
    
    /**
     * 将rms的货架数据同步到wms货架数据上
     *
     */
    // @Service
    public class ShelfScoreSynImpl implements ShelfScoreSyn {
        // 查询rms的货架数据同步到wms货架数据上
        @Autowired
        private AthenaBaseShelfMapper athenaBaseShelfMapper;
    
        @Autowired
        private BaseShelfMapper baseShelfMapper;
    
        @Override
        public void execute() {
            /*
               1.从数据库查询货架位置信息
               2.把数据插入到wms
               3.返回插入的值
             */
            List<AthenaBaseShelf> athenaBaseShelfList = athenaBaseShelfMapper.selectBaseShelf();
            Map<String, AthenaBaseShelf> athenaBaseShelfMap = athenaBaseShelfList.stream().collect(Collectors.toMap(AthenaBaseShelf::getShelfCode, e -> e));
            List<BaseShelf> baseShelfList = baseShelfMapper.selectWmsBaseShelf();
            List<BaseShelf> updatedBaseShelfList = updateBaseShelf(athenaBaseShelfMap, baseShelfList);
            for (BaseShelf baseShelf : updatedBaseShelfList) {
                System.out.println(baseShelf);
            }
        }
    
        private List<BaseShelf> updateBaseShelf(Map<String, AthenaBaseShelf> athenaBaseShelfMap, List<BaseShelf> baseShelfList) {
            int shiftParameter = AlgoSysConfigUtils.getIntegerValue("hephaestus.shelfscoring.shiftParameter", 1000);
            for (BaseShelf baseShelf : baseShelfList) {
                if (athenaBaseShelfMap.keySet().contains(baseShelf.getShelfCode())) {
                    AthenaBaseShelf athenaBaseShelf = athenaBaseShelfMap.get(baseShelf.getShelfCode());
                    if (athenaBaseShelf.getLocationX() != null || athenaBaseShelf.getLocationY() != null || athenaBaseShelf.getLocationX() > 0 || athenaBaseShelf.getLocationY() > 0) {
                        int shiftLocationX = athenaBaseShelf.getLocationX() * shiftParameter;
                        int shiftLocationY = athenaBaseShelf.getLocationY() * shiftParameter;
                        if (!(baseShelf.getLocax() == shiftLocationX && baseShelf.getLocay() == shiftLocationY)) {
                            baseShelf.setLocax(shiftLocationX);
                            baseShelf.setLocay(shiftLocationY);
                            baseShelfMapper.updateWmsBaseShelf(baseShelf);
                        }
                    }
                }
            }
            return baseShelfList;
        }
    }

### 3.解决问题： ###

--------------------

它没有交给spring进行管理：ShelfScoreSynImpl ,在上面加个注释就好了，把它交给spring管理。

当加了@service之后，就没有这种异常了。
