标签： mongodb gradle spring-boot

我正在使用Spring Data MongoDB，以下是我的存储库+模型：

public interface postJobRepository extends Repository<postJob,String> {
    List<postJob> findAll();
    Optional<postJob> findOne(long id);
    postJob save(postJob saved);
}

这是我的模特：

@Document
public final class postJob {

    @Id
    private long id;
    private  int userid;
    private String Summary;
    private String Category;
    private String SubCategory;
    private String Description;
    private String ReferenceDocs;
    private  int Budget;
    private String INR;
    private String Location;
    private String City;
    private String State;
    private String Duration;
    private String dateTimeOfPost;
    private String Status;
    private String Private;

    public int getUserid() {
        return userid;
    }
    public String getSummary() {
        return Summary;
    }
    public String getCategory() {
        return Category;
    }
    public String getSubCategory() {
        return SubCategory;
    }
    public String getDescription() {
        return Description;
    }
    public String getReferenceDocs() {
        return ReferenceDocs;
    }
    public int getBudget() {
        return Budget;
    }
    public String getINR() {
        return INR;
    }
    public String getLocation() {
        return Location;
    }
    public String getCity() {
        return City;
    }
    public String getState() {
        return State;
    }
    public String getDuration() {
        return Duration;
    }
    public String getDateTimeOfPost() {
        return dateTimeOfPost;
    }
    public String getStatus() {
        return Status;
    }
    public String getPrivate() {
        return Private;
    }

    public void update(int userid, String summary, String category, String   subCategory, String description,
                       String referenceDocs, int budget, String iNR, String location, String  city, String state, String duration,
                       String dateTimeOfPost, String status, String private1) {

        this.userid = userid;
        Summary = summary;
        Category = category;
        SubCategory = subCategory;
        Description = description;
        ReferenceDocs = referenceDocs;
        Budget = budget;
        INR = iNR;
        Location = location;
        City = city;
        State = state;
        Duration = duration;
        this.dateTimeOfPost = dateTimeOfPost;
        Status = status;
        Private = private1;
    }
    public postJob() {

    }
}

但是，当我运行应用程序时，我得到以下异常：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'postJobController' defined in file [D:\Development\postJob\bin\postJob\postJobController.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [postJob.postJobService]: : Error creating bean with name 'postJobServiceImp' defined in file [D:\Development\postJob\bin\postJob\postJobServiceImp.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [postJob.postJobRepository]: : Error creating bean with name 'postJobRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property findOne found for type postJob!; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'postJobRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property findOne found for type postJob!; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'postJobServiceImp' defined in file [D:\Development\postJob\bin\postJob\postJobServiceImp.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [postJob.postJobRepository]: : Error creating bean with name 'postJobRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property findOne found for type postJob!; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'postJobRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property findOne found for type postJob!

2 个答案:

答案 0 :(得分：0)

你的问题措辞非常糟糕......

我从异常中看到的是，postJobRepository似乎期望PostJob具有名为findOne的属性。由于这显然不存在，因此您会遇到此异常。

请提供PostJob和PostJobrepository的代码以获取更详细的答案

更新：

将您的存储库更改为：

public interface postJobRepository extends Repository<postJob,Long> {

  List<postJob> findAll();
  Optional<postJob> findOne(Long id);
  postJob save(postJob saved);
}

存储库的第二个参数是id postJob

的类型

同时在postJob Long类型long而不是spark

中设置ID

最后一个建议：类名应以大写字母开头

答案 1 :(得分：0)

当您从Repository延伸时，您必须提供两个泛型：

  • 模型的类型（postJob）
  • ID的类型（带@Id）字段的注释

在您的情况下，@Id带注释的字段为long，而您的存储库则从Repository<postJob, String>延伸。这会导致麻烦，因为现在Spring无法找到具有findOne()参数的String方法。

要解决此问题，您必须修复通用并从Repository<postJob, Long>扩展。

请注意，字段名必须以小写字母开头（与INR，Budget，Summary，Location，...不同，并且类名称开始用大写字母（与postJob不同）。

我不确定这是否会导致其他问题，但有些框架需要正确的字段/ getter / setter命名才能工作。
