泛型方法+反射，解决重复代码问题

1.泛型方法声明

放在返回结果前，进行修饰，传参List infoList 进行参数的泛型支持

public <T> List<SigmaInstance> generateInstancesByDataInfoList(List<T> infoList,
                                                              Map<Long, GroupInfo> groupMap,
                                                              Map<String, AppInfo> appMap) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {
}

2.使用范例

/**
     * 基于传递过来的对象列表，不同对象获取不同的属性写到internalAddress属性中去
     * @param infoList
     * @param groupMap
     * @param appMap
     * @param <T>
     * @return
     * @throws NoSuchMethodException
     * @throws InvocationTargetException
     * @throws IllegalAccessException
     */
    public <T> List<SigmaInstance> generateInstancesByDataInfoList(List<T> infoList,
                                                              Map<Long, GroupInfo> groupMap,
                                                              Map<String, AppInfo> appMap) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {
        List<SigmaInstance> sigmaInstances = Lists.newArrayList();
        String getGroupIdMethodName = "getGroupId";
        for (T devopsInstanceInfo:infoList) {
            Method groupMethod = devopsInstanceInfo.getClass().getMethod(getGroupIdMethodName);
            Long groupId = (Long) groupMethod.invoke(devopsInstanceInfo);
            GroupInfo devopsGroupInfo = groupMap.get(groupId);
            if (null == devopsGroupInfo){
                LOG.warn("Get devopsGroupInfo error,devopsInstanceInfo: {}",JsonUtils.toJSONString(devopsInstanceInfo));
                continue;
            }
            AppInfo devopsAppInfo = appMap.get(devopsGroupInfo.getAppEnName());
            if (null == devopsAppInfo){
                LOG.warn("Get devopsAppInfo error,devopsGroupInfo: {}",JsonUtils.toJSONString(devopsGroupInfo));
                continue;
            }
            SigmaInstance sigmaInstance = new SigmaInstance();
            sigmaInstance.setGroupEnName(devopsGroupInfo.getGroupName());
            sigmaInstance.setAppEnName(devopsAppInfo.getAppEnName());
            sigmaInstance.setPlatform(Platform.DEVOPS);
            sigmaInstance.setEnv(generateEnvTypeByDevopsGroup(devopsGroupInfo));
            Method getInternalAddressMethod = devopsInstanceInfo.getClass().getMethod(fieldMethodNameMap.get(devopsInstanceInfo.getClass()));
            sigmaInstance.setInternalAddress((String) getInternalAddressMethod.invoke(devopsInstanceInfo));
            sigmaInstance.setUseType(useTypeMap.get(devopsInstanceInfo.getClass()));
            sigmaInstance.setCreateTime(new Date());
            sigmaInstance.setCreateUser(DevopsProcessor.class.getSimpleName());
            sigmaInstance.setUpdateTime(new Date());
            sigmaInstance.setUpdateUser(DevopsProcessor.class.getSimpleName());
            sigmaInstances.add(sigmaInstance);
        }
        return sigmaInstances;
    }
