mongodb - org.springframework.beans.factory.UnsatisfiedDependencyException:

Question

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);
}

这是我的模型:

@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，当我运行该应用程序时，出现以下异常:

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!

Answer 1

从Repository扩展时，您必须提供两个泛型:

模型的类型(postJob)

ID的类型(带有@Id的字段)注释

在您的情况下，带 @Id注释的字段是 long，而您的存储库是从 Repository<postJob, String>扩展的。这会造成麻烦，因为现在Spring无法找到具有 findOne()参数的 String方法。

要修复它，您必须修复通用类并从 Repository<postJob, Long>扩展。

请记住，字段名必须以小写开头(不同于 INR， Budget， Summary， Location，...)，并且类名必须以大写字母开头(与 postJob不同)。

我不确定这是否会导致其他问题，但是某些框架需要正确的字段/获取者/设置者命名才能工作。
