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 {@Beforepublic void prepare() {AlgoSysConfigUtils.setValue("hephaestus.debug.enabled", "true");}@Autowiredprivate ShelfScoreSyn shelfScoreSyn;@Testpublic 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@Autowiredprivate AthenaBaseShelfMapper athenaBaseShelfMapper;@Autowiredprivate BaseShelfMapper baseShelfMapper;@Overridepublic void execute() {/*1.从数据库查询货架位置信息2.把数据插入到wms3.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。
