The main thing is this sentence (org.hibernate.MappingException: Error reading resource: com / test / hibernate / bean / User.hbm.xml), what is causing this problem?

vampireii

User.hbm.xml is wrong, must be declared for element type "hibernate-mapping".

This is it


<? xml version = "1.0" encoding = 'UTF-8'?>
<! DOCTYPE hibernate-mapping PUBLIC "-// Hibernate / Hibernate Mapping DTD 3.0 // EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping package = "com.test.hibernate.bean">

    <class name = "User" table = "user">
        <id name = "id" column = "id" type = "java.lang.Integer">
            <generator class = "native" />
        </ id>
        <property name = "username">
            <column name = "username" type = "java.lang.String" />
        </ property>
        <property name = "password">
            <column name = "pwd" type = "java.lang.String" />
        </ property>
    </ class>
    
</ hibernate-mapping>

airwalk

<property name = "username" type = "java.lang.String">
            <column name = "username" />
        </ property>
Is your type wrong? Look again, can you?

冰火共舞

I did it upstairs and it was such a problem
"Hibernate: insert into user (username, pwd) values ​​(?,?) Select scope_identity ()"
org.hibernate.exception.GenericJDBCException: could not insert: [com.test.hibernate.bean.User]

Don't understand why

airwalk

When you write the save () method, user.id must also be assigned. If you don't want to set the id, you need to write HQL to implement.

Thank you upstairs, solved. Primary key problem
