How should i solve Exception “Unable to resolve path” while executing a query in hibernate?

Question

I am trying to test a simple application that uses hibernate and annotations.I have the follwing database tables with the following foreign key constraints.

create table user_info 
(
mobile_number varchar(16) primary key, 
gender char(1),
language varchar(4))


create table user_order_info
(order_id integer(16) not null primary key auto_increment,   
mobile_number varchar(16) not null,
location_name varchar(32) not null, 
foreign key(mobile_number) references user_info(mobile_number),

create table user_queue_order_info
(queue_id integer(16) not null primary key auto_increment,
order_id integer(16),   
mobile_number varchar(16) not null,  
order_value integer(8) not null,   
foreign key(mobile_number) references user_info(mobile_number),
foreign key(order_id) references user_order_info(order_id) on delete cascade)

And the respective entity table of the above table are as follows:

@Entity
@Table(name = "user_info")
public class UserInfo implements Serializable {         
private String mobileNumber;    
private char gender;
private String language;
    //getters and setters and constructors
}


@Entity
@Table(name = "user_order_info")

public UserOrderInfo implements Serializable {  
private long orderId;
private String locationName;        
private UserInfo userInfo;
    //getters and setters and constructors
}


@Entity
@Table(name = "user_queue_order_info")

public class UserQueueOrderInfo implements Serializable {   

private long queueId;   
private int orderValue; 
private UserInfo userInfo;
private UserOrderInfo userOrderinfo;
    //getters and setters , constructors

The problem is whenI try to use UserOrderInfoDao to access the database by using the following method, exception is coming.

public UserOrderInfo UserOrderInfoByMobileNumber(String mobileNumber ) {
List<UserOrderInfo> userOrderInfoList =    sessionFactory.getCurrentSession().createQuery("from UserOrderInfo where userInfo.mobileNumber='"+mobileNumber+"'").list();
    if(!userOrderInfoList.isEmpty()){
        return userOrderInfoList.get(0);
    }
    return null;
}

When i try to debug by tracing the exception,the exception coming is:

Exception Unable to resolve path [userInfo.mobileNumber], unexpected token [userInfo] [from com.appls.entity.UserOrderInfo where userInfo.mobileNumber='7770909090']

why is this problem is coming?I am waiting for your valuble suggestions.

And I have done the mappings in getters and setters in the following way:

@Id 
@Column(name = "mobile_number")
public String getMobileNumber() {
    return mobileNumber;
}

Same for other fields also.

Entity for User_info is

    private String mobileNumber;        
private char gender;
private String language;

@Id 
@Column(name = "mobile_number")
public String getMobileNumber() {
    return mobileNumber;
}
public void setMobileNumber(String mobileNumber) {
    this.mobileNumber = mobileNumber;
}

@Column(name = "gender")
public char getGender() {
    return gender;
}
public void setGender(char gender) {
    this.gender = gender;
}

@Column(name = "language")
public String getLanguage() {
    return language;
}
public void setLanguage(String language) {
    this.language =language;
}

public UserInfo() {
    super();        
}


public UserInfo(String mobileNumber){
    super();
    this.mobileNumber = mobileNumber;
}

public UserInfo(String mobileNumber, char gender, String language) {
    super();
    this.mobileNumber =mobileNumber;
    this.gender = gender;
    this.language = language;

}   

@Override
public String toString() {
return "{\"mobileNumber\": \"" + this.mobileNumber
            + "\", \"gender\": \"" + this.gender
            + "\", \"language\": \"" + this.language }";
}

Answer 1

either change private String mobileNumber; including getter/setter

as private String mobile_number;

Or annotate it

@Column(name="mobile_number")
private String mobileNumber;  

Same with private String locationName; and private String orderValue;

Query should be like createQuery("from UserOrderInfo userOrderInfo where userOrderInfo.userInfo.mobileNumber='"+mobileNumber+"'").list()

Answer 2

您应该将您的mobileNumber字段更改为DB中的mobile_number或注释中的pojo。
