What's Wrong?

删除模型时没有删除s2_model_rela表中模型的关联关系，导致指标探索时出现空指针异常

private static void dfs(ModelSchemaResp model, Map<Long, ModelSchemaResp> modelMap,
            Set<Long> visited, Set<Long> modelCluster) {
        visited.add(model.getId()); // model is null
        modelCluster.add(model.getId());
        for (Long neighborId : model.getModelClusterSet()) {
            if (!visited.contains(neighborId)) {
                dfs(modelMap.get(neighborId), modelMap, visited, modelCluster);
            }
        }
    }

应该还有其他地方也会有类似的异常

What You Expected?

删除模型时应同步删除s2_model_rela表中模型的关联关系，并且应该添加判空处理

private static void dfs(ModelSchemaResp model, Map<Long, ModelSchemaResp> modelMap,
            Set<Long> visited, Set<Long> modelCluster) {
        visited.add(model.getId());
        modelCluster.add(model.getId());
        for (Long neighborId : model.getModelClusterSet()) {
            if (!visited.contains(neighborId) && modelMap.containsKey(neighborId)) {
                dfs(modelMap.get(neighborId), modelMap, visited, modelCluster);
            }
        }
    }
