No persistent classes found for query Class:from Com.vrv.paw.domain.User

In the consolidation spring+hibernate times this error, the Sessionfactory configuration is as follows:

    <BeanID= "Sessionfactory"class= "Org.springframework.orm.hibernate4.LocalSessionFactoryBean">.......<!--Hibernate class files that are configured automatically by scanning annotations -        < Propertyname= "Packagestoscan">//Last found to be a mistake at the place            <List>                <value>Sys.model</value>            </List>        </ Property>
.......    </Bean>

As in the XML configuration above, Packagetoscan is configured to configure the Hibernate class in an annotated manner, as in the following way:

Package Sys.model;import Java.io.serializable;import Java.util.date;import javax.persistence.column;import Javax.persistence.entity;import Javax.persistence.id;import Javax.persistence.table;import Javax.persistence.temporal;import Javax.persistence.TemporalType;@Entity @table (name = "User")public class UserInfo implements Serializable {private static final long serialversionuid = 8427996478439081619L;    fields private String ID;    private String name;    Private String pwd;    Private Date Createdatetime;    Private Date Modifydatetime;         /** Full Constructor */public UserInfo (string ID, string name, string pwd, date createdatetime, date modifydatetime) {        This.id = ID;        THIS.name = name;        This.pwd = pwd;        This.createdatetime = Createdatetime;    This.modifydatetime = Modifydatetime; }@Id @Column (name = "Id", unique = true, Nullable = false, Length = $)Public String GetId () {return this.id;    } public void SetId (String id) {this.id = ID; }@Column (name = "Name", unique = true, Nullable = false, length = +)Public String GetName () {return this.name;    } public void SetName (String name) {this.name = name; }@Column (name = "PWD", nullable = false, length = +)Public String getpwd () {return this.pwd;    } public void SetPwd (String pwd) {this.pwd = pwd; } @Temporal (Temporaltype.timestamp)//If this is the temporaltype.date, then the time is stored in the database will be "2015-07-16 00:00:00" This form, time and seconds are zero @    Column (name = "Createdatetime", length = 7) public Date Getcreatedatetime () {return this.createdatetime;    } public void Setcreatedatetime (Date createdatetime) {this.createdatetime = Createdatetime; } @Temporal (Temporaltype.timestamp) @Column (name = "Modifydatetime", length = 7) public Date Getmodifydatetime ()    {return this.modifydatetime;    } public void Setmodifydatetime (Date modifydatetime) {this.modifydatetime = Modifydatetime; } @Override Public String toString () {return ' [ID: ' + ID + ' name: ' + name + ' PassWord: ' + pwd + ' Createda    Tetime: "+ createdatetime +" Modifydatetiem: "+ modifydatetime +"] "; }}

But the way I used to integrate the *.hbm.xml

The most convenient way to do this is to use "mappingdirectorylocations"

    <BeanID= "Sessionfactory"class= "Org.springframework.orm.hibernate3.LocalSessionFactoryBean">.......< Propertyname= "Mappingdirectorylocations">            <List>                <value>Classpath:com/vrv/paw/domain</value>            </List>        </ Property>
   </Bean>

Extended:

Mappingresources, Mappinglocations, mappingdirectorylocations
The difference between them:
1. Mappingresources: Specify the specific mapping file name under Classpath

<name= "mappingresources">       <value  ></value>   </Property>   

2. Mappinglocations: You can specify any file path, and you can specify a prefix: classpath, file, and so on

 <  property  name  = "Mappinglocations"  >  Span style= "color: #0000ff;" ><  value  > /web-inf/ Petclinic.hbm.xml </ >  </ property  >  

<name= "mappinglocations">       <value  ></value>   </Property>   

You can also specify by using a wildcard character, ' * ' to specify a file (path) name, ' * * ' to specify multiple file (path) names, for example:

<name= "mappinglocations">       <value  ></value>   </Property>   

The above configuration is the Hbm.xml file under any maps path under the Com/company/domain package is loaded as a mapping file

3. Mappingdirectorylocations: Specifying the mapped file path

<name= "mappingdirectorylocations">  <List  >     <value>web-inf/hibernatemappings</ value >     </ List >   </  Property >   

You can also use Classpath to point out

 <  property  name  = "Mappingdirectorylocations"   <  list  >  <  value  >  classpath:/xxx/package/</  Value  >  </ list  >  </ property  >  

Summary: Annotated mode configuration of the Hibernate class and *.hbm.xml mode configuration of the class, configuration Sessionfactory when configured in a different way, which I did not notice before
