Springcloud学习笔记34--文件存储信息新增功能(post方式提交,@RequestBody注解接收raw格式的application/json,JsonUtil工具类)

1.controller

利用OssDetailsDto实体类接收多个参数，同时利用@RequestBody注解接收postman测试所发的raw格式的application/json)

@Api(tags="bs_file_store")
@RestController
@RequestMapping("/test/bsFileStore")
@Slf4j
public class BsFileStoreController extends JeecgController<BsFileStore, IBsFileStoreService> {
    @Autowired
    private IBsFileStoreService bsFileStoreService;/**
     *   添加
     *
     * @param ossDetailsDto
     * @return
     */
    @AutoLog(value = "bs_file_store-添加")
    @ApiOperation(value="bs_file_store-添加", notes="bs_file_store-添加")
    @PostMapping(value = "/add")
    public Result<?> add(@RequestBody OssDetailsDto ossDetailsDto) {

        return Result.OK(bsFileStoreService.add(ossDetailsDto)?Result.OK("添加成功"):Result.error("添加失败！"));
    }
}

2.service接口及其实现类

(1)service接口

public interface IBsFileStoreService extends IService<BsFileStore> {/**
     * 新建存储
     * @param ossDetailsDto
     * @return
     */
    boolean add(OssDetailsDto ossDetailsDto);
}

(2)实现类

@Service
@DS("multi-datasource1")
@Slf4j
public class BsFileStoreServiceImpl extends ServiceImpl<BsFileStoreMapper, BsFileStore> implements IBsFileStoreService {
    @Autowired
    private BsFileStoreMapper bsFileStoreMapper;

    @Autowired
    private PmOsInfoMapper pmOsInfoMapper;

    @Autowired
    private PmLocalstoreInfoMapper pmLocalstoreInfoMapper;

    @Autowired
    private PmOsClustersMapper pmOsClustersMapper;

    @Autowired
    private PmOsBucketMapper pmOsBucketMapper;

    private final String LOCAL=StoreTypeEnum.LOCAL.getCode();
    private final String OSS=StoreTypeEnum.OSS.getCode();

    @Override
    @Transactional(rollbackFor = Exception.class)   //数据库事务操作
    public boolean add(OssDetailsDto ossDetailsDto) {
        String type = ossDetailsDto.getStoreType();
        String osName = ossDetailsDto.getOsName();
        if(OSS.equals(type)){
            PmOsInfo osInfo=new PmOsInfo();
            BeanUtils.copyProperties(ossDetailsDto,osInfo );
            pmOsInfoMapper.insert(osInfo);
            //集群关系插入
            ossDetailsDto.getClusters().forEach(i->{
                i.setOsName(osName);
                pmOsClustersMapper.insert(i);
            }) ;

        }

        return true;
    }
}

3.postman测试

application/json格式的测试数据生成

JsonUtil工具类:

package org.jeecg.modules.util;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;

import lombok.extern.slf4j.Slf4j;
import org.jeecg.modules.dto.OssDetailsDto;
import org.jeecg.modules.entity.PmOsClusters;

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

@Slf4j
public class JsonUtil {
    private static ObjectMapper objectMapper=new ObjectMapper();

    static {
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);
    }

    public static <T> String obj2JsonStr(T t) throws JsonProcessingException {
        if(t instanceof  String ){
            return (String) t;
        }
        return objectMapper.writeValueAsString(t);
    }

    public static <T> T jsonStr2Obj(String str,Class<T> clazz) throws IOException {
        if(str==null){
            return null;
        }

        //若反序列化类型为String,则直接返回
        if(String.class.getTypeName().equals(clazz.getTypeName())) {
            return (T) str;
        }
        return (T) objectMapper.readValue(str, clazz);
    }

    public static <T> T jsonStr2Obj(String str,TypeReference typeReference) throws IOException{
        if(str==null){
            return null;
        }
        //若反序列化类型为String,则直接返回
        if(String.class.getTypeName().equals(typeReference.getType().getTypeName())) {
            return (T) str;
        }
        return (T) objectMapper.readValue(str, typeReference);
    }

    public static String formatJsonStr(Object o) throws IOException{
        //判断是否为空
        if(o==null){
            return null;
        }
        Object tmp=o;
        //若输入参数为String类型，则尝试转换为Object,转换失败则直接返回
        if(tmp instanceof String){
            String tmpStr=(String) tmp;
            if(tmpStr.length()==0){
                return tmpStr;
            }
            try {
                tmp=jsonStr2Obj(tmpStr, Object.class);
            } catch (JsonProcessingException e) {
                log.warn("反序列化失败，无法反序列化[{}]",tmpStr);
                return tmpStr;
            }
        }
        try {
            return objectMapper.writerWithDefaultPrettyPrinter().writeValueAsString(tmp);
        } catch (JsonProcessingException e) {
            //若转格式化失败，则返回toString
            log.warn("",e);
            return tmp.toString();
        }
    }

    public static String jsonGenerate() throws JsonProcessingException {
        OssDetailsDto ossDetailsDto=new OssDetailsDto();
        ossDetailsDto.setStoreType("1");
        ossDetailsDto.setOsDesc("hello");
        ossDetailsDto.setOsName("fleptest1014");
        ossDetailsDto.setLocalPath("d:/test");
        ossDetailsDto.setEndpointFirst("l27.0.0.1");
        ossDetailsDto.setAccessKey("aaa");
        ossDetailsDto.setSecretKey("sss");
        ossDetailsDto.setStatus("1");
        List<PmOsClusters> osClustersList=new ArrayList<>();
        PmOsClusters pmOsClusters=new PmOsClusters();
        pmOsClusters.setOsName("lucky01");
        pmOsClusters.setStatus("1");
        osClustersList.add(pmOsClusters);
        ossDetailsDto.setClusters(osClustersList);
        String s = obj2JsonStr(ossDetailsDto);
        return s;
    }

    public static void main(String[] args) throws Exception {
        System.out.println(jsonGenerate());
    }


 }

测试json实例:

{"id":null,"osName":"fleptest1014","osDesc":"hello","storeType":"1","endpointFirst":"l27.0.0.1","endpointSecond":null,"endpointThird":null,"localPath":"d:/test","pathDesc":null,"accessKey":"aaa","secretKey":"sss","status":"1","clusters":[{"id":null,"osName":"lucky01","clusterName":null,"status":"1","createBy":null,"createTime":null,"updateBy":null,"updateTime":null}],"buckets":null}
