Java 原因：org.springframework.data.mapping.model.MappingException:在com.common.model.EmployeeTerritory上找不到属性territoryID！-弹簧靴

我正在开发

Spring Boot MongoDB

示例。在本例中，我试图通过SpringDataMongo存储库查询获取TerritoryID，但遇到以下错误。请引导

仅用于澄清目的。我并不认为这是一个明确的答案

也许你误解了我。您必须遵守bean的java命名约定

@Document(collection="employee-territories")
    public class EmployeeTerritory {

    @Id
    private ObjectId id;
    @Field
    private String EmployeeID;
    @Field(value="TerritoryID")
    private Integer TerritoryID;
    // setters and getters
 }

应该是

 @Document(collection="employee-territories")
 public class EmployeeTerritory {

     @Id
     private ObjectId id;
     @Field
     private String employeeID;
     @Field(value="TerritoryID")
     private Integer territoryID;
     // setters and getters
 }

---

我重复一遍，这可能是您出现异常的原因。

我能够解决此错误。请参阅下面我的代码片段。根据spring data mongo文件（参考第12.1.1节）：

您的Mongo DB字段使用驼峰大小写字母及其各自的setter和getter，但根据doc“标识符的默认字段名为'\u id'，可以通过

@field

注释进行自定义。”

如果您愿意通过任何字段获取数据，则需要对所有字段应用类似的逻辑

使用下面的，将工作

@Document(collection="employee-territories")
public class EmployeeTerritory {

    @Id
    private ObjectId id;
    @Field("EmployeeID")
    private Integer employeeID;
    @Field("TerritoryID")
    private Integer territoryID;

    public ObjectId getId() {
        return id;
    }
    public void setId(ObjectId id) {
        this.id = id;
    }
    public Integer getEmployeeID() {
        return employeeID;
    }
    public void setEmployeeID(Integer employeeID) {
        this.employeeID = employeeID;
    }
    public Integer getTerritoryID() {
        return territoryID;
    }
    public void setTerritoryID(Integer territoryID) {
        this.territoryID = territoryID;
    }
}

您是否尝试过将类中的字段命名为“territoryId”？这不是一个愚蠢的问题。使用

territoryId

并添加getter/setter（spring可能会使用它们）。对spring进行一些调试可能有助于out@RC. 奇怪的是，我们的建议最终被接受为正确答案，不是吗？@RubioRic你应该习惯它；）（如果你真的“不喜欢”，你可以否决这个答案）@javaHelper，这很奇怪。异常似乎是指模型org.springframework.data.mapping.model.MappingException。模型映射。我不相信你的评论。有人否决了我的澄清？谢谢你的回答：）什么？？？但这就是我45分钟前在评论中提出的解决方案！javatechnology和javaHelper都鄙视它。00
