Question

我有实体文件ad.java：

    package com.realestate.data.domain;

import java.util.Date;

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document
public class Ad {

    @Id
    private String id;
    private String city;
    private int price;
    private String phonenumber;
    private int roomnumber;
    private Date dateinsert;
    private Date datepublish;
    private String freedescribetext;

    public String getPhonenumber() {
        return phonenumber;
    }

    public void setPhonenumber(String phonenumber) {
        this.phonenumber = phonenumber;
    }

    public void setId(String iD) {
        id = iD;
    }

    public String getCity() {
        return city;
    }
    public void setCity(String city) {
        this.city = city;
    }
    public int getPrice() {
        return price;
    }
    public void setPrice(int price) {
        this.price = price;
    }
    public int getRoomnumber() {
        return roomnumber;
    }
    public void setRoomnumber(int roomnumber) {
        this.roomnumber = roomnumber;
    }
    public Date getDateinsert() {
        return dateinsert;
    }
    public void setDateinsert(Date dateinsert) {
        this.dateinsert = dateinsert;
    }
    public Date getDatepublish() {
        return datepublish;
    }
    public void setDatepublish(Date datepublish) {
        this.datepublish = datepublish;
    }
    public String getFreedescribetext() {
        return freedescribetext;
    }
    public void setFreedescribetext(String freedescribetext) {
        this.freedescribetext = freedescribetext;
    }
    public String getId() {
        return id;
    }


}

我也有控制器和存储库等。

AdRepository.java

package com.realestate.data.repository;

import org.springframework.data.mongodb.core.MongoOperations;
import org.springframework.data.mongodb.repository.MongoRepository;

import com.realestate.data.domain.Ad;

public interface AdRepository extends MongoRepository<Ad, String>, MongoOperations {

}

servlet-context.xml

web.xml

<?xml version="1.0" encoding="UTF-8"?>

        <servlet-name>appServlet</servlet-name>

</web-app>

root-context.xml实际上是空的：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <!-- Root Context: defines shared resources visible to all other web components -->

</beans>

现在我收到以下错误：

`Servlet /ads threw load() exception org.springframework.data.mapping.PropertyReferenceException: No property execute found for type com.realestate.data.domain.Ad`.

谢谢

Answer 1

我无法解释原因，但是如果我从

更改存储库的实现

public interface AdRepository extends MongoRepository<Ad, String>, MongoOperations{}

到

public interface AdRepository extends MongoRepository<Ad, String>{}

问题消失了。

也许MongoRepository和MongoOperations会造成某种冲突，我不知道。
