如何使用SPRING DATA从MONGODB中按值数组获取文档？

我的文档

{
    "id": "5b18fdef89d67e272025f2e3",   
    "date": "2018-05-10 11:31:37",
    "active": true,
    "obsolete": false,
    "tenant": {
        "id": "5ad847e54925fb0fa4424e1a"
    },
    "plan": {
        "id": "5ad7115f7b4152204c86fce6"
    },
    "log": [
        "5b18fdef89d67e272025f2e4"
    ],
    "lineItem": [
        "5b18fdef89d67e272025f2e5",
        "5b18fdef89d67e2720259899",
        "5b18fdef89d67e272025sd5s"
    ]
}
{
        "id": "5b18fdef89d67e272025f232",   
        "date": "2018-05-12 11:31:37",
        "active": true,
        "obsolete": false,
        "tenant": {
            "id": "5ad847e54925fb0fa4424e1a"
        },
        "plan": {
            "id": "5ad7115f7b4152204c86fce6"
        },
        "log": [
            "5b18fdef89d67e272025f23434"
        ],
        "lineItem": [
            "5b18fdef89d67e272025f111",
            "5b18fdef89d67e2720259222",
            "5b18fdef89d67e272025s333"
        ]
    }

我想按lineItem数组过滤文档。如果我将lineItem的值设置为“ 5b18fdef89d67e2720259222”，则它将是包含相同lineitem的返回文档。

模型类

@Document(collection = "trn_inventory")
public class Inventory {
    @Id
    private String id;
    private String date;
    private List<String> lineitem;

    private String tenant, plan;
    private List<String> log;
    private boolean active, obsolete;
    //getters and setters

}

存储库

@Repository
public interface InventoryRep extends MongoRepository<Inventory, String> {  
    public List<Inventory> findByLineitemIn(String lineitem);
}

我在存储库中犯了错误。花了很长时间后，我自己找到了（愚蠢的编码器）。问题在于 findByLineitemIn 方法的参数是应该为列表类型的字符串。

这是已更正的存储库...

@Repository
public interface InventoryRep extends MongoRepository<Inventory, String> {  
    public List<Inventory> findByLineitemIn(List<String> lineitem);
}

这有多愚蠢。不是吗？我认为这将对像我这样的其他编码人员有所帮助。 ;）
