工具类-注入service

工具类中这样子注入是失败的，空指针。因为ClientMasterDataService没有被实例化

@Resource
private ClientMasterDataService clientMasterDataService;

通过构造注入

public class AuthorityUtils {

    private ClientMasterDataService clientMasterDataService;

    public AuthorityUtils(ClientMasterDataService clientMasterDataService){
        this.clientMasterDataService = clientMasterDataService;
    }

/**
 * 根据集团id，公司id，获取权限
 * @param groupId
 * @param companyId
 * @return
 * @throws Exception
 */
public ResultModel<MasterDataOperateDTO> postDataEntity(Long groupId,Long companyId) throws Exception {
    Long groupId1 = null;
    Long companyId1 = null;
    if (groupId != null) {
        groupId1 = groupId;
    }
    if (companyId != null) {
        companyId1 = companyId;
    }
    return clientMasterDataService.getMasterDataOperator(RequestUtil.getCurrentUserName(), groupId1, companyId1);
 }
}
